- 00:00:34,267 --> 00:00:37,011
- Over the past 250 years -
- 2
- 00:00:37,061 --> 00:00:44,394
- - We've made the biggest
- scientific experiment ever.
- 3
- 00:00:44,444 --> 00:00:47,939
- Since the Industrial Revolution -
- 4
- 00:00:47,989 --> 00:00:54,612
- - We have sent 1.4 trillion tons of coal
- straight out into the atmosphere.
- 5
- 00:00:54,662 --> 00:01:01,619
- It has changed life on earth,
- especially in the Arctic.
- 6
- 00:01:01,669 --> 00:01:07,834
- The world's melting snow and ice
- has caused climate change -
- 7
- 00:01:07,884 --> 00:01:12,296
- - threatening life on earth.
- 8
- 00:01:12,346 --> 00:01:17,051
- But the worrying vision of the future
- need not be written in stone.
- 9
- 00:01:17,101 --> 00:01:20,888
- It has long existed
- alternative to fossil fuels.
- 10
- 00:01:20,938 --> 00:01:27,103
- We recently discovered a way
- to remove carbon dioxide from the atmosphere -
- 11
- 00:01:27,153 --> 00:01:31,774
- - which gives us a chance
- to reverse climate change.
- 12
- 00:01:31,824 --> 00:01:35,445
- If we manage to return
- climate change -
- 13
- 00:01:35,495 --> 00:01:40,283
- - It would be an accomplishment that lacks
- in the history of humanity.
- 14
- 00:01:40,333 --> 00:01:42,869
- But the clock is ticking.
- 15
- 00:01:42,919 --> 00:01:47,540
- The researchers say we have to
- Take the measures immediately.
- 16
- 00:01:47,590 --> 00:01:52,879
- The seriousness of the situation requires us
- listens to the impartial experts.
- 17
- 00:01:52,929 --> 00:01:58,551
- They've presented facts like those
- have devoted their lives to developing.
- 18
- 00:01:58,601 --> 00:02:01,220
- It's their turn to be heard.
- 19
- 00:02:01,270 --> 00:02:05,349
- They are scientists,
- researchers and innovators -
- 20
- 00:02:05,399 --> 00:02:13,007
- - who have found solutions for that
- preserve life in our common world.
- 21
- 00:02:14,867 --> 00:02:18,929
- ROCKY MOUNTAINS
- COLORADO
- 22
- 00:02:29,006 --> 00:02:34,278
- Some projects require
- manual sampling.
- 23
- 00:02:37,348 --> 00:02:41,410
- One of them applies
- CO2 emissions over a longer period.
- 24
- 00:02:43,312 --> 00:02:50,086
- Someone must venture out
- and take the test every Tuesday.
- 25
- 00:02:51,779 --> 00:02:57,468
- I am the one who can go out with
- the snow car and make the measurements.
- 26
- 00:02:58,745 --> 00:03:03,307
- The long-term protocol
- should be conducted as always.
- 27
- 00:03:04,625 --> 00:03:07,912
- Monitoring and registering
- what we do with our atmosphere -
- 28
- 00:03:07,962 --> 00:03:10,456
- - Is an important but difficult task.
- 29
- 00:03:10,506 --> 00:03:15,253
- The last 50 years have
- dedicated researchers from all over the world -
- 30
- 00:03:15,303 --> 00:03:17,755
- -rest every week to the same places-
- 31
- 00:03:17,805 --> 00:03:24,095
- - to measure the greenhouse gases
- that causes climate change.
- 32
- 00:03:24,145 --> 00:03:27,849
- We are at just over 3 400 meters,
- up on Niwot Ridge.
- 33
- 00:03:27,899 --> 00:03:31,352
- It is located in the front edge
- of Rocky Mountains in Colorado.
- 34
- 00:03:31,402 --> 00:03:39,051
- This NOAA station for
- long-term sampling of CO2 values.
- 35
- 00:03:40,828 --> 00:03:45,533
- These glass cubes
- used to take the samples.
- 36
- 00:03:45,583 --> 00:03:50,872
- When we have filled them with air
- We send them to our office.
- 37
- 00:03:50,922 --> 00:03:53,875
- On NOAA's lab in Boulder
- the samples are analyzed
- 38
- 00:03:53,925 --> 00:03:57,420
- - along with similar
- tubes from the rest of the world.
- 39
- 00:03:57,470 --> 00:04:01,924
- The reason why the samples
- usually taken so high
- 40
- 00:04:01,974 --> 00:04:07,555
- - is that the air is so well mixed here.
- The sample corresponds to the whole atmosphere.
- 41
- 00:04:07,605 --> 00:04:09,766
- There is a small opening in the ceiling.
- 42
- 00:04:09,816 --> 00:04:14,729
- When I turn on the pump
- sucked the air into the tubes.
- 43
- 00:04:14,779 --> 00:04:19,484
- These measure the carbon cycle
- and the greenhouse gases
- 44
- 00:04:19,534 --> 00:04:23,637
- -There CO2 and methane are the largest.
- 45
- 00:04:24,664 --> 00:04:30,519
- When they took the first test in 1968
- showed it at 322 ppm.
- 46
- 00:04:32,380 --> 00:04:35,291
- We don't know what
- this sample shows yet-
- 47
- 00:04:35,341 --> 00:04:42,490
- - but it's probably around 408.
- And that's an increase.
- 48
- 00:04:44,976 --> 00:04:50,039
- Now I stop everything and everything
- do the work for next week's test.
- 49
- 00:05:05,329 --> 00:05:12,161
- One of NOAA's assignments from the beginning
- was to measure CO2 in the atmosphere
- 50
- 00:05:12,211 --> 00:05:15,623
- - and other gases
- which affects the carbon cycle.
- 51
- 00:05:15,673 --> 00:05:20,545
- Two kinds of samples are collected
- weekly from all over the world.
- 52
- 00:05:20,595 --> 00:05:23,423
- We want to see how the gases
- change over time.
- 53
- 00:05:23,473 --> 00:05:26,909
- To do that, we take
- constantly new samples.
- 54
- 00:05:28,019 --> 00:05:31,597
- Right now we have 60 collection points.
- 55
- 00:05:31,647 --> 00:05:37,520
- The samples are mostly taken in remote places,
- far from inhabited areas.
- 56
- 00:05:37,570 --> 00:05:42,650
- With this equipment we measure
- 57
- 00:05:42,700 --> 00:05:49,907
- It's carbon dioxide, methane,
- carbon monoxide, molecular hydrogen
- 58
- 00:05:49,957 --> 00:05:52,744
- - nitrous oxide and sulfur hexafluoride.
- 59
- 00:05:52,794 --> 00:05:57,415
- The system is running five days a week.
- 60
- 00:05:57,465 --> 00:06:02,086
- I assemble the air samples
- the manifold and start the measurement.
- 61
- 00:06:02,136 --> 00:06:04,572
- Then I can leave.
- 62
- 00:06:29,705 --> 00:06:33,910
- I am the head of NOAA's Global
- Greenhouse Gas Reference Network.
- 63
- 00:06:33,960 --> 00:06:37,455
- The goal of the global network
- 64
- 00:06:37,505 --> 00:06:41,834
- - is to produce data
- fully calibrated
- 65
- 00:06:41,884 --> 00:06:44,754
- - carefully checked
- and documented.
- 66
- 00:06:44,804 --> 00:06:49,509
- The information is equally reliable
- in a hundred years or more.
- 67
- 00:06:49,559 --> 00:06:56,516
- So, according to climate change
- continues in the future
- 68
- 00:06:56,566 --> 00:07:01,312
- - there is information for the researchers
- which they can rely on.
- 69
- 00:07:01,362 --> 00:07:04,691
- Then they can diagnose
- what really happened
- 70
- 00:07:04,741 --> 00:07:08,677
- - and how climate change
- really works.
- 71
- 00:07:09,579 --> 00:07:16,077
- The modern CO2 measurements
- started by Dave Keeling-
- 72
- 00:07:16,127 --> 00:07:23,167
- - at the oceanographic institution.
- In 1956 he took samples along the west coast.
- 73
- 00:07:23,217 --> 00:07:29,173
- He saw that in the afternoon,
- wherever he was -
- 74
- 00:07:29,223 --> 00:07:32,009
- - so was the concentration
- the same everywhere.
- 75
- 00:07:32,559 --> 00:07:35,972
- Then he was struck by the thought
- that there may be something
- 76
- 00:07:36,022 --> 00:07:38,349
- - We can call
- "Background concentration".
- 77
- 00:07:38,399 --> 00:07:43,146
- He began regular measurements
- at Mauna Loa in Hawaii
- 78
- 00:07:43,196 --> 00:07:45,423
- -and also on the Antarctic coast.
- 79
- 00:07:47,033 --> 00:07:52,864
- Towards the end of the last ice age,
- between 20,000 and 11,000 years ago
- 80
- 00:07:52,914 --> 00:07:59,829
- - increased CO2 levels by 80 ppm,
- from about 200 to 280.
- 81
- 00:07:59,879 --> 00:08:05,043
- It went slow. It took 6,000 years
- for the CO2 level to rise by 80 ppm.
- 82
- 00:08:05,993 --> 00:08:07,236
- Sixteen years.
- 83
- 00:08:08,721 --> 00:08:14,469
- Before the industries arrived, before 1850,
- the CO2 level was around 280 ppm.
- 84
- 00:08:14,519 --> 00:08:18,931
- And today we see an increase
- by 2 ppm per year.
- 85
- 00:08:18,981 --> 00:08:25,480
- That increase is due
- 100 percent on man.
- 86
- 00:08:25,530 --> 00:08:32,528
- The increase we see today,
- compared to the geological history
- 87
- 00:08:32,578 --> 00:08:35,264
- - I should almost call
- an explosion.
- 88
- 00:08:36,999 --> 00:08:42,938
- It is instant,
- from a geological time perspective.
- 89
- 00:08:46,759 --> 00:08:50,963
- Carbon dioxide has risen dramatically
- since the industrial revolution.
- 90
- 00:08:51,013 --> 00:08:53,574
- What does that really mean to us?
- 91
- 00:08:54,851 --> 00:08:59,889
- We know too much
- carbon dioxide damages the climate.
- 92
- 00:08:59,939 --> 00:09:03,351
- It changes the weather behavior
- and life support system -
- 93
- 00:09:03,401 --> 00:09:06,587
- - which we depend on
- to survive.
- 94
- 00:09:08,406 --> 00:09:12,235
- We have always known that toxicity
- associated with fossil fuels-
- 95
- 00:09:12,285 --> 00:09:16,197
- - But we always thought
- that it would attack the human
- 96
- 00:09:16,247 --> 00:09:19,909
- -or other living individuals.
- 97
- 00:09:19,959 --> 00:09:24,122
- It is not until my lifetime
- 98
- 00:09:24,172 --> 00:09:26,749
- - as it has become
- frighteningly obvious-
- 99
- 00:09:26,799 --> 00:09:31,671
- - the accumulation of CO2 in the atmosphere
- has got the heat to rise.
- 100
- 00:09:31,721 --> 00:09:38,761
- The greenhouse effect affects
- life on the planet as a whole.
- 101
- 00:09:38,811 --> 00:09:42,390
- Once I understood it
- in the mid 90s
- 102
- 00:09:42,440 --> 00:09:46,752
- - we needed to start talking about it,
- which we have done since then.
- 103
- 00:09:51,240 --> 00:09:54,652
- When we're talking about
- dangerous global warming
- 104
- 00:09:54,702 --> 00:10:01,993
- - we mean when it's about
- two degrees Celsius warmer
- 105
- 00:10:02,043 --> 00:10:04,787
- - compared with
- pre-industrial time.
- 106
- 00:10:04,837 --> 00:10:07,749
- This is when we start to see the worst
- 107
- 00:10:07,799 --> 00:10:11,586
- - and maybe irrevocably
- effects of climate change:
- 108
- 00:10:11,636 --> 00:10:16,924
- Melting Polaris,
- which gives rising sea levels.
- 109
- 00:10:16,974 --> 00:10:22,972
- Permanently dry at warmer
- latitudes and much more.
- 110
- 00:10:23,022 --> 00:10:27,060
- It will be disaster
- about the larger ice melts
- 111
- 00:10:27,110 --> 00:10:30,897
- - on Greenland and West Antarctica.
- 112
- 00:10:30,947 --> 00:10:35,151
- Then all major coastal towns are affected
- in the world of flooding.
- 113
- 00:10:35,201 --> 00:10:36,944
- The areas on land are decreasing.
- 114
- 00:10:36,994 --> 00:10:41,199
- The result is environmental refugees,
- when people leave those regions.
- 115
- 00:10:41,249 --> 00:10:47,246
- People leave the tropics because
- it gets too hot man.
- 116
- 00:10:47,296 --> 00:10:54,003
- The crops in the tropics are affected
- the heat and production will decrease.
- 117
- 00:10:54,053 --> 00:10:57,673
- In short, it becomes a world
- with less surface
- 118
- 00:10:57,723 --> 00:11:01,719
- - less food and water,
- stuck with more people.
- 119
- 00:11:01,769 --> 00:11:06,123
- That's the recipe for
- a national security disaster.
- 120
- 00:11:19,620 --> 00:11:25,159
- I have worked with
- to measure carbon dioxide for over 30 years.
- 121
- 00:11:25,209 --> 00:11:30,081
- If only we had done something
- ate this for 20 years ago-
- 122
- 00:11:30,131 --> 00:11:33,400
- - I had done something else today,
- but I am left.
- 123
- 00:11:36,955 --> 00:11:40,091
- Looking at the relationship
- between carbon dioxide and sea level
- 124
- 00:11:40,141 --> 00:11:43,052
- - is there
- a couple of interesting moments:
- 125
- 00:11:43,102 --> 00:11:48,057
- When CO2 levels rise to 400 ppm
- 126
- 00:11:48,107 --> 00:11:54,272
- - the heat may loose large ice blocks
- from Antarctica and Greenland.
- 127
- 00:11:54,322 --> 00:11:57,650
- The ice blocks are
- what we call marine based.
- 128
- 00:11:57,700 --> 00:12:01,696
- The base of the ice deck in western Antarctica
- is below sea level
- 129
- 00:12:01,746 --> 00:12:04,282
- - Because it
- is stuck in the sediment.
- 130
- 00:12:04,332 --> 00:12:07,285
- Once it starts to melt
- it becomes a runaway train.
- 131
- 00:12:07,335 --> 00:12:09,895
- No one knows how to stop it.
- 132
- 00:12:10,713 --> 00:12:15,109
- We are dangerously close to it right now.
- 133
- 00:12:17,428 --> 00:12:22,341
- The next threshold is around
- CO2 levels of 600-700 ppm.
- 134
- 00:12:22,391 --> 00:12:28,222
- Then it is so hot that it does not exist
- some landis remain on the planet.
- 135
- 00:12:28,272 --> 00:12:32,001
- Then the sea level becomes
- about 80 meters higher.
- 136
- 00:12:33,111 --> 00:12:38,883
- We are heading for 600-700 ppm.
- 137
- 00:12:41,244 --> 00:12:47,033
- It is an interesting threshold moment
- regarding our relationship with the planet.
- 138
- 00:12:47,083 --> 00:12:54,332
- Should we press our climate system
- so much out of balance
- 139
- 00:12:54,382 --> 00:12:58,694
- - that we risk
- to digest all landis?
- 140
- 00:13:10,064 --> 00:13:11,557
- Yes, it has changed.
- 141
- 00:13:11,607 --> 00:13:16,270
- Iceland's nature has been affected
- of climate change.
- 142
- 00:13:16,320 --> 00:13:19,982
- It is clearly visible
- along the southern coast, for example.
- 143
- 00:13:20,032 --> 00:13:26,030
- Our largest glacier, Vatnajökull,
- or the "water glacier" -
- 144
- 00:13:26,080 --> 00:13:28,741
- - has decreased quite a bit.
- 145
- 00:13:28,791 --> 00:13:33,496
- There is an interesting observation
- which everyone notices
- 146
- 00:13:33,546 --> 00:13:36,207
- -When they drive along the southern coast today.
- 147
- 00:13:36,257 --> 00:13:41,796
- When you drive over Iceland's longest bridge,
- which is almost a kilometer
- 148
- 00:13:41,846 --> 00:13:45,383
- - You notice it almost
- There is no water underneath.
- 149
- 00:13:45,433 --> 00:13:52,748
- Why are you building such a long bridge
- over almost no water at all?
- 150
- 00:13:54,108 --> 00:13:57,937
- It depends on climate change.
- 151
- 00:13:57,987 --> 00:14:04,802
- The river has changed direction
- because of the glacier's decline.
- 152
- 00:14:06,746 --> 00:14:11,909
- Now we have a kind of monument-
- 153
- 00:14:11,959 --> 00:14:16,147
- - which symbolizes the past.
- 154
- 00:14:29,894 --> 00:14:34,457
- The Arctic is a changed place today.
- 155
- 00:14:35,233 --> 00:14:41,272
- Here is the climate change
- impact as most extreme.
- 156
- 00:14:41,322 --> 00:14:45,193
- The researchers notice
- that what is happening on the Arctic
- 157
- 00:14:45,243 --> 00:14:49,322
- - has a big impact
- on the rest of the planet.
- 158
- 00:14:49,372 --> 00:14:53,576
- I work with measuring greenhouse gases
- at the Arctic station
- 159
- 00:14:53,626 --> 00:14:58,247
- - and to find out how
- vaxthusg
- 160
- 00:14:58,297 --> 00:15:01,709
- I'm worried about it
- rising temperature in the region
- 161
- 00:15:01,759 --> 00:15:06,255
- - and the impact it can have
- on all Arctic systems.
- 162
- 00:15:06,305 --> 00:15:10,885
- I think that is extremely important
- to be aware of-
- 163
- 00:15:10,935 --> 00:15:15,556
- - that the sea ice decreased
- and all other changes
- 164
- 00:15:15,606 --> 00:15:20,127
- - can change the entire weather system,
- which has a global impact.
- 165
- 00:15:21,571 --> 00:15:28,219
- We know the changes in the Arctic
- are not limited there.
- 166
- 00:15:30,872 --> 00:15:34,534
- I have worked with the sea ice
- the past fifty years.
- 167
- 00:15:34,584 --> 00:15:39,372
- The entire Arctic has changed
- very much during that time.
- 168
- 00:15:39,422 --> 00:15:43,418
- Not enough
- that the ice has decreased in area.
- 169
- 00:15:43,468 --> 00:15:48,214
- The decrease is really visible.
- The great ice creams from
- 170
- 00:15:48,264 --> 00:15:51,801
- - with their ramparts of pack ice
- and very thick ice cover ...
- 171
- 00:15:51,851 --> 00:15:56,831
- Much of it
- dramatic scenery is gone.
- 172
- 00:15:58,316 --> 00:16:04,063
- I recently visited the Bering Sea
- for research purposes.
- 173
- 00:16:04,113 --> 00:16:08,426
- In that region is usually found
- very melted, but we saw no one.
- 174
- 00:16:10,286 --> 00:16:15,324
- HISTORICAL BLOCK ON THE SEA:
- 1.8 - 4.5 meters
- 175
- 00:16:15,374 --> 00:16:19,871
- The ice was very thin,
- maybe just 30 centimeters thick.
- 176
- 00:16:19,921 --> 00:16:23,541
- The North Sea is no longer
- a continent of ice.
- 177
- 00:16:23,591 --> 00:16:26,335
- It's just water in the summer.
- 178
- 00:16:26,385 --> 00:16:30,798
- It's a huge loss,
- not just by nature's beauty-
- 179
- 00:16:30,848 --> 00:16:36,054
- - but also with regard to
- the physics of how the planet works.
- 180
- 00:16:36,104 --> 00:16:39,140
- The ice disappears
- if the climate gets warmer.
- 181
- 00:16:39,190 --> 00:16:45,021
- It is an obvious consequence,
- but is worse than that.
- 182
- 00:16:45,071 --> 00:16:48,399
- There will be many chain reactions -
- 183
- 00:16:48,449 --> 00:16:54,680
- - that affects the planet much more
- than only the ice creams decrease.
- 184
- 00:16:56,582 --> 00:17:00,328
- The Arctic is heated three times faster
- than the rest of the world-
- 185
- 00:17:00,378 --> 00:17:05,416
- - whereupon the temperature difference between
- The Arctic and lower latitudes decrease.
- 186
- 00:17:05,466 --> 00:17:09,629
- That means the jet stream
- becomes weaker.
- 187
- 00:17:09,679 --> 00:17:13,925
- It is weakened from
- to have been an almost straight line
- 188
- 00:17:13,975 --> 00:17:19,180
- - to become more wavy
- and reach both north and south.
- 189
- 00:17:19,230 --> 00:17:24,727
- This can mean that the polar air
- reaches down to lower latitude
- 190
- 00:17:24,777 --> 00:17:27,772
- - Like that usually
- only when in a sector
- 191
- 00:17:27,822 --> 00:17:30,525
- - but in the sector
- to the east or west of the
- 192
- 00:17:30,575 --> 00:17:34,404
- - Hot air comes further north
- than it should.
- 193
- 00:17:34,454 --> 00:17:39,200
- The result is the bizarre weather
- that people have talked about.
- 194
- 00:17:39,250 --> 00:17:44,122
- When the air masses cause
- so extreme weather changes
- 195
- 00:17:44,172 --> 00:17:48,960
- - it happens to be at the latitudes
- where most food is produced.
- 196
- 00:17:49,010 --> 00:17:55,116
- Suddenly food production is affected
- of the polar changes.
- 197
- 00:17:56,809 --> 00:18:02,498
- One cannot remove as much ice
- without affecting much else.
- 198
- 00:18:05,026 --> 00:18:11,757
- Arctic's strongest sea ice divides
- the first time since the measurements began
- 199
- 00:18:13,576 --> 00:18:17,321
- Consequences
- of our actions begin to show itself.
- 200
- 00:18:17,371 --> 00:18:22,243
- Researchers' predictions
- rather than expected.
- 201
- 00:18:22,293 --> 00:18:28,332
- We may experience storms, drought,
- floods and fires -
- 202
- 00:18:28,382 --> 00:18:32,545
- - which is gradually becoming more and more
- intensive and unpredictable.
- 203
- 00:18:32,595 --> 00:18:37,717
- NEW HEATING CORDS OVER
- ALL PLANET LAST WEEK
- 204
- 00:18:37,767 --> 00:18:43,931
- THE WORLD BRINS AND SWIMMERS OVER
- CLIMATE CHANGES ARE HERE
- 205
- 00:18:43,981 --> 00:18:49,879
- BURNS IN CALIFORNIA 2018
- SEED FROM THE SPACE
- 206
- 00:18:53,616 --> 00:19:00,573
- HOT HOT MONTH AS EVER
- HAVE BEEN RECALLED ON THE EARTH
- 207
- 00:19:00,623 --> 00:19:05,978
- THE RESEARCHERS ONLY KNOW A CASE:
- IT WILL BE WORSE
- 208
- 00:19:16,848 --> 00:19:22,745
- The fires began almost simultaneously
- in several places.
- 209
- 00:19:23,896 --> 00:19:29,852
- More than 7,000 buildings were destroyed
- of which about 3,000 homes.
- 210
- 00:19:29,902 --> 00:19:32,772
- In the beginning when the fires were like the worst
- 211
- 00:19:32,822 --> 00:19:38,444
- - maybe evacuated
- 100,000 people.
- 212
- 00:19:38,494 --> 00:19:42,848
- It is a collective trauma.
- 213
- 00:19:43,958 --> 00:19:47,078
- It sounded and looked like a war zone.
- 214
- 00:19:47,128 --> 00:19:49,706
- Hanley-fire
- reached here after 24 hours.
- 215
- 00:19:49,756 --> 00:19:52,667
- It burned roughly
- same impression here in 24 hours.
- 216
- 00:19:52,717 --> 00:19:55,211
- Near 200 buildings were burned down.
- 217
- 00:19:55,261 --> 00:19:59,799
- This fire started in the evening
- and reached Santa Rosa in four hours.
- 218
- 00:19:59,849 --> 00:20:02,385
- They cannot be compared,
- besides the prints.
- 219
- 00:20:02,435 --> 00:20:06,931
- Commander who came here
- to lead the rescue work-
- 220
- 00:20:06,981 --> 00:20:10,435
- - just shook his head:
- "I've never seen anything like it."
- 221
- 00:20:10,485 --> 00:20:12,353
- "And I've been with a long time."
- 222
- 00:20:12,403 --> 00:20:19,027
- It's hardly any comfort,
- But that's where we are now.
- 223
- 00:20:19,077 --> 00:20:24,407
- With such winds, how do we protect
- citizens and infrastructure?
- 224
- 00:20:24,457 --> 00:20:29,120
- What can we do to it?
- stop as good as possible?
- 225
- 00:20:29,170 --> 00:20:36,127
- Where has suffered five years of drought
- who hit bushes and trees.
- 226
- 00:20:36,177 --> 00:20:42,925
- The wind forces up at Geyser Peak
- measured at 48 meters per second.
- 227
- 00:20:42,975 --> 00:20:47,472
- What to do when it blows so hard
- and a fire occurs?
- 228
- 00:20:47,522 --> 00:20:52,001
- One can only try to figure out
- its direction and how fast it goes.
- 229
- 00:20:55,238 --> 00:20:58,441
- I never thought that the fire
- would leave the mountains
- 230
- 00:20:58,491 --> 00:21:01,969
- -and smooth Santa Rosa with the ground.
- 231
- 00:21:02,662 --> 00:21:05,114
- Cars have been evicted.
- 232
- 00:21:05,164 --> 00:21:09,577
- Large pieces of glowing coal
- 233
- 00:21:09,627 --> 00:21:13,498
- - brought by the wind,
- a good bit in front of the fire.
- 234
- 00:21:13,548 --> 00:21:17,001
- You see trees with broken branches.
- 235
- 00:21:17,051 --> 00:21:20,112
- They have not been burned off, they were broken off.
- 236
- 00:21:21,722 --> 00:21:25,301
- natural disasters
- has become so common now-
- 237
- 00:21:25,351 --> 00:21:28,554
- - that people know
- that they will suffer.
- 238
- 00:21:28,604 --> 00:21:33,142
- It's not the question, but when.
- 239
- 00:21:33,192 --> 00:21:39,023
- It is an alarm clock for everyone.
- Climate change is here
- 240
- 00:21:39,073 --> 00:21:42,384
- -and you have to plan for it.
- 241
- 00:21:47,582 --> 00:21:52,870
- Climate change causes more
- species are endangered.
- 242
- 00:21:52,920 --> 00:21:56,332
- But that's not the first time.
- 243
- 00:21:56,382 --> 00:22:01,754
- Studies of geological findings
- has demonstrated a connection
- 244
- 00:22:01,804 --> 00:22:07,493
- - between high carbon levels and the latest ones
- five periods of mass death.
- 245
- 00:22:08,686 --> 00:22:15,977
- It's a natural law to carbon cycle
- affects the structure of life.
- 246
- 00:22:16,027 --> 00:22:19,272
- Every time a massive increase
- of the colonies have taken place -
- 247
- 00:22:19,322 --> 00:22:24,277
- - the motley weave of life has weakened
- and sometimes collapsed.
- 248
- 00:22:24,327 --> 00:22:30,825
- MIT
- ATMOSPHERE AND PLANETARY RESEARCH
- 249
- 00:22:30,875 --> 00:22:36,998
- I have worked with
- carbon cycle connection
- 250
- 00:22:37,048 --> 00:22:38,750
- -with the presence of mass death
- 251
- 00:22:38,800 --> 00:22:43,195
- - and whether the carbon cycle
- is unstable when it happens.
- 252
- 00:22:44,680 --> 00:22:49,886
- The carbon cycle is there
- life and the environment interact.
- 253
- 00:22:49,936 --> 00:22:54,265
- You can see it as a big one
- circular flow between photosynthesis
- 254
- 00:22:54,315 --> 00:22:57,727
- - which is the process as
- takes carbon dioxide out of the atmosphere
- 255
- 00:22:57,777 --> 00:23:03,107
- - converts it to oxygen
- and plant material or organic carbon.
- 256
- 00:23:03,157 --> 00:23:06,361
- The reverse reaction in the circle
- is called respiration-
- 257
- 00:23:06,411 --> 00:23:12,266
- - which is when the plant material
- converted to carbon dioxide.
- 258
- 00:23:13,459 --> 00:23:18,331
- During a completed lap
- takes the carbon cycle around 100 gigatons of coal
- 259
- 00:23:18,381 --> 00:23:22,168
- - from the atmosphere and the seas,
- and return it every year.
- 260
- 00:23:22,218 --> 00:23:26,255
- So it's 100 gigatons out,
- and 100 gigatons back in.
- 261
- 00:23:26,305 --> 00:23:31,386
- Of this, we contribute 8 percent,
- with fossil fuels.
- 262
- 00:23:31,436 --> 00:23:36,808
- An increase of 8 percent compared to
- what had circulated normally.
- 263
- 00:23:36,858 --> 00:23:41,504
- That's more than what
- the volcanoes supply the system.
- 264
- 00:23:53,583 --> 00:23:59,539
- The planet is constantly working
- to restore the balances.
- 265
- 00:23:59,589 --> 00:24:02,709
- It's the water cycle,
- the nitrogen cycle and the carbon cycle.
- 266
- 00:24:02,759 --> 00:24:06,587
- You can see it
- as a constant flow.
- 267
- 00:24:06,637 --> 00:24:11,092
- One way for the planet to do it
- was to take everything
- 268
- 00:24:11,142 --> 00:24:15,471
- - that was in the dinosaurs
- and the plants on land
- 269
- 00:24:15,521 --> 00:24:20,810
- - and squeeze it together
- for oil and fossil fuels.
- 270
- 00:24:20,860 --> 00:24:27,108
- It was hidden for a very long time,
- And we are a very young species.
- 271
- 00:24:27,158 --> 00:24:30,278
- But we were curious and dug up
- 272
- 00:24:30,328 --> 00:24:35,158
- - the coal that the earth had hidden away.
- 273
- 00:24:35,208 --> 00:24:40,413
- Then we burned it up without understanding
- that it was like burning furniture
- 274
- 00:24:40,463 --> 00:24:43,232
- - Indoors with closed windows.
- 275
- 00:24:44,175 --> 00:24:48,921
- What happens is
- that the planet backs back.
- 276
- 00:24:48,971 --> 00:24:53,676
- There is a surplus
- of coal in the atmosphere.
- 277
- 00:24:53,726 --> 00:24:58,639
- It leads to the living conditions-
- 278
- 00:24:58,689 --> 00:25:02,226
- - here on earth is put out of balance.
- 279
- 00:25:02,276 --> 00:25:06,481
- As a biologist,
- when i see climate change
- 280
- 00:25:06,531 --> 00:25:11,361
- - I see rising sea levels
- and melting polaris.
- 281
- 00:25:11,411 --> 00:25:13,804
- I see that as evidence.
- 282
- 00:25:14,789 --> 00:25:20,828
- But when we look at it
- how biological organisms
- 283
- 00:25:20,878 --> 00:25:26,901
- - responds to the warmer temperatures,
- they have already started to move.
- 284
- 00:25:27,760 --> 00:25:31,506
- They move towards the poles
- to cool down.
- 285
- 00:25:31,556 --> 00:25:35,760
- They move upwards
- from lower mountain areas.
- 286
- 00:25:35,810 --> 00:25:39,013
- Whole areas of distribution are moved.
- 287
- 00:25:39,063 --> 00:25:42,975
- Sometimes they also move
- without their helpers.
- 288
- 00:25:43,025 --> 00:25:46,521
- If a plant moves north
- does not cope with its pollinators.
- 289
- 00:25:46,571 --> 00:25:53,636
- In a scientific, boring language
- you call it ecological disturbance.
- 290
- 00:25:54,871 --> 00:26:01,202
- If we change the conditions
- who created all this ...
- 291
- 00:26:01,252 --> 00:26:08,734
- Even us. Then we come ...
- It will track down.
- 292
- 00:26:11,971 --> 00:26:18,511
- When the carbon cycle is unstable
- Do the things we don't understand.
- 293
- 00:26:18,561 --> 00:26:23,558
- On the geological time scale
- are there events
- 294
- 00:26:23,608 --> 00:26:27,169
- - within the carbon cycle,
- where things changed.
- 295
- 00:26:30,364 --> 00:26:37,221
- One such was the paleocene eocene
- thermal maxima, 55 million years ago.
- 296
- 00:26:38,498 --> 00:26:43,494
- Then there is much worse,
- disastrous events
- 297
- 00:26:43,544 --> 00:26:48,082
- - in the form of mass extinction.
- The worst is called Perm-trias extinction.
- 298
- 00:26:48,132 --> 00:26:50,793
- 95% OF EVERY LIFE DOG OUT
- FOR 250 MILLION YEARS LATE
- 299
- 00:26:50,843 --> 00:26:56,090
- Then the story looks, but we do
- doing today is another problem-
- 300
- 00:26:56,140 --> 00:26:58,676
- - We know what is going on.
- 301
- 00:26:58,726 --> 00:27:04,682
- We know that we have added CO2
- by using fossil fuels.
- 302
- 00:27:04,732 --> 00:27:08,895
- Then the question is whether it is at risk
- to induce similar events
- 303
- 00:27:08,945 --> 00:27:10,980
- - as we have seen in the past.
- 304
- 00:27:11,030 --> 00:27:14,192
- I would call it
- instability in the carbon cycle.
- 305
- 00:27:14,242 --> 00:27:18,905
- When small changes
- turns into big changes.
- 306
- 00:27:18,955 --> 00:27:22,808
- It is a scientific definition
- of a disaster.
- 307
- 00:27:24,168 --> 00:27:29,982
- But at individual level is
- the loss of one's home a disaster.
- 308
- 00:27:43,626 --> 00:27:47,416
- Climate change will
- cause the world's largest refugee crisis
- 309
- 00:27:59,366 --> 00:28:04,367
- Climate change soon
- a threat to biodiversity
- 310
- 00:28:04,417 --> 00:28:09,580
- Rising temperatures threaten
- to eradicate wild animals and plants
- 311
- 00:28:09,630 --> 00:28:15,420
- Climate change is killing
- corals in the Great Barrier Reef
- 312
- 00:28:15,470 --> 00:28:22,701
- The changes threaten ancient trees,
- But that's not all
- 313
- 00:28:35,531 --> 00:28:40,928
- We are all climate refugees now
- 314
- 00:28:50,421 --> 00:28:55,209
- We can still avoid it
- dangerous break point at two degrees.
- 315
- 00:28:55,259 --> 00:28:59,297
- But for every year that we are passive-
- 316
- 00:28:59,347 --> 00:29:03,509
- - it becomes increasingly difficult
- to limit our carbon emissions
- 317
- 00:29:03,559 --> 00:29:07,872
- - and stay under
- the two-degree heating.
- 318
- 00:29:34,006 --> 00:29:37,735
- UN climate conference 2015
- Paris, France
- 319
- 00:29:40,346 --> 00:29:47,953
- World leader celebrates the Paris Agreement:
- "A big step for humanity"
- 320
- 00:29:56,946 --> 00:30:04,553
- KOLKLOCKAN:
- Time left before the budget is spent
- 321
- 00:30:17,133 --> 00:30:20,753
- We know we've sent out
- too much carbon in the atmosphere.
- 322
- 00:30:20,803 --> 00:30:23,423
- But how much is too much?
- 323
- 00:30:23,473 --> 00:30:26,843
- The researchers have come up with
- what that figure is -
- 324
- 00:30:26,893 --> 00:30:32,473
- - and has entered a carbon budget
- which shows what margin life has.
- 325
- 00:30:32,523 --> 00:30:37,854
- The budget shows where we are today,
- how much more coal we can burn -
- 326
- 00:30:37,904 --> 00:30:45,052
- - and how much must be removed
- to sustain life on earth.
- 327
- 00:30:47,789 --> 00:30:52,702
- The biggest challenge is, according to me
- dangerous climate change.
- 328
- 00:30:52,752 --> 00:30:58,666
- If we want to avoid dangerous
- climate change, we must realize
- 329
- 00:30:58,716 --> 00:31:03,629
- - that atmosphere, like human
- waste disposal site has its limit.
- 330
- 00:31:03,679 --> 00:31:08,676
- We can release about
- 800 gigatons of CO2 in the atmosphere
- 331
- 00:31:08,726 --> 00:31:12,096
- -in that limit.
- 332
- 00:31:12,146 --> 00:31:18,895
- But over the past five years
- have we already released 200 gigatons
- 333
- 00:31:18,945 --> 00:31:22,607
- - which means that in two decades
- 334
- 00:31:22,657 --> 00:31:26,611
- - We have already used up
- our limited space.
- 335
- 00:31:26,661 --> 00:31:33,701
- In Paris it was important
- that the leaders of the whole world agreed
- 336
- 00:31:33,751 --> 00:31:38,289
- - to limit the temperature increase
- well below two degrees.
- 337
- 00:31:38,339 --> 00:31:41,292
- That's the safety margin
- and it is important-
- 338
- 00:31:41,342 --> 00:31:45,213
- - that more than a hundred nations
- stand behind it.
- 339
- 00:31:45,263 --> 00:31:50,593
- If you think of the volume in
- the ball symbolizes the CO2
- 340
- 00:31:50,643 --> 00:31:57,141
- - still in the ground
- in the form of coal, oil and gas.
- 341
- 00:31:57,191 --> 00:32:00,311
- Here we have the amount of coal.
- 342
- 00:32:00,361 --> 00:32:05,400
- If we want to limit the increase
- up to two degrees globally
- 343
- 00:32:05,450 --> 00:32:10,571
- - Let's just let go
- this is a little carbon in the atmosphere.
- 344
- 00:32:10,621 --> 00:32:15,410
- At the same time we have
- much more coal left in the ground
- 345
- 00:32:15,460 --> 00:32:21,124
- - not going out into the atmosphere about
- the increase should be kept below two degrees.
- 346
- 00:32:21,174 --> 00:32:23,459
- The question is therefore
- how it should go together?
- 347
- 00:32:23,509 --> 00:32:28,673
- The next 20 years are
- an enormously important time span.
- 348
- 00:32:28,723 --> 00:32:34,429
- We must separate the financial
- growth from the growing emissions.
- 349
- 00:32:34,479 --> 00:32:38,558
- At the middle of the century, we must
- be down in zero emissions
- 350
- 00:32:38,608 --> 00:32:43,688
- - and after 2050 we need
- even negative emissions.
- 351
- 00:32:43,738 --> 00:32:47,650
- The charcoal clock only informs
- humanity about where we stand today.
- 352
- 00:32:47,700 --> 00:32:53,823
- It shows how we dispose of
- the limited space in the atmosphere.
- 353
- 00:32:53,873 --> 00:32:56,851
- It's a huge challenge
- for Humanity.
- 354
- 00:33:08,346 --> 00:33:14,135
- Science says the climate crisis
- is a problem we ourselves have created.
- 355
- 00:33:14,185 --> 00:33:17,388
- But that's also
- a problem we can solve
- 356
- 00:33:17,438 --> 00:33:23,269
- We must stop dropping coal
- and transition to renewable energy.
- 357
- 00:33:23,319 --> 00:33:28,775
- It is also vital
- to remove carbon from the atmosphere.
- 358
- 00:33:28,825 --> 00:33:34,364
- Climate change is possible
- turn back - if we act now.
- 359
- 00:33:34,414 --> 00:33:39,660
- Research has found solutions
- that can reduce the amount of coal -
- 360
- 00:33:39,710 --> 00:33:42,455
- - So we end up in level
- with pre-industrial time.
- 361

- NORWAY CALIFORNIA Redwood forest
- 362
- 00:33:45,925 --> 00:33:49,003
- There are only two measures
- that helps the atmosphere.
- 363
- 00:33:49,053 --> 00:33:52,006
- You either stop
- greenhouse gas
- 364
- 00:33:52,556 --> 00:33:54,717
- - or you lower the CO2 level.
- That's all.
- 365
- 00:33:54,767 --> 00:33:59,680
- The first one can be done through
- more efficient and cleaner energy.
- 366
- 00:33:59,730 --> 00:34:05,978
- The second is through photosynthesis.
- Either through agriculture and forestry
- 367
- 00:34:06,028 --> 00:34:09,691
- - or plankton and kelp in the seas.
- There are only two measures.
- 368
- 00:34:09,741 --> 00:34:12,944
- That way it's pretty simple.
- 369
- 00:34:12,994 --> 00:34:19,492
- Previously, all solutions have
- always just focused on energy.
- 370
- 00:34:19,542 --> 00:34:23,329
- Energy, energy and energy,
- which is fully understandable.
- 371
- 00:34:23,379 --> 00:34:28,710
- Of course it is a good idea
- to stop CO2 emissions.
- 372
- 00:34:28,760 --> 00:34:34,048
- But when the emphasis has been put on
- clean energy sources such as sun and wind
- 373
- 00:34:34,998 --> 00:34:40,371
- - He's almost ruled out
- the remaining solutions.
- 374
- 00:34:42,690 --> 00:34:44,183
- Drawdown:
- 375
- 00:34:44,233 --> 00:34:48,187
- To reverse climate change
- by pulling coal out of the atmosphere.
- 376
- 00:34:48,237 --> 00:34:54,277
- The purpose of the drawdown was to redo
- the 80 solutions we had developed
- 377
- 00:34:54,327 --> 00:34:59,991
- - could return
- global warming within 30 years.
- 378
- 00:35:00,041 --> 00:35:02,744
- From reducing to turning down.
- 379
- 00:35:02,794 --> 00:35:07,832
- The emission curve shows
- that we have a choice.
- 380
- 00:35:07,882 --> 00:35:12,754
- If we increase the scope
- of some of the solutions-
- 381
- 00:35:12,804 --> 00:35:17,633
- - we can achieve drawdown around 2050.
- 382
- 00:35:17,683 --> 00:35:25,166
- I agree with the odds
- is against us, but I must take it.
- 383
- 00:35:53,886 --> 00:35:55,546
- My name is Linwood Gill.
- 384
- 00:35:55,596 --> 00:36:00,259
- I am the chief forest guard at
- Usal Redwood Forest Company.
- 385
- 00:36:00,309 --> 00:36:03,596
- Usal Redwood Forest
- is a general forest
- 386
- 00:36:03,646 --> 00:36:07,975
- - owned by the non-profit foundation
- Redwood Forest Foundation.
- 387
- 00:36:08,025 --> 00:36:10,520
- The forest is 50,000 acres.
- 388
- 00:36:10,570 --> 00:36:17,443
- The purpose is to preserve the forest,
- partly as an economic security
- 389
- 00:36:17,493 --> 00:36:23,366
- - and to protect it
- natural environment for animals and fish
- 390
- 00:36:23,416 --> 00:36:26,452
- - but also to remove
- coal out the atmosphere.
- 391
- 00:36:26,502 --> 00:36:31,833
- It is one of ours
- main mission right now.
- 392
- 00:36:31,883 --> 00:36:37,380
- It is an important part of the fight
- against climate change.
- 393
- 00:36:37,430 --> 00:36:41,259
- Usal Redwood Forest
- is a very young redwood forest.
- 394
- 00:36:41,309 --> 00:36:47,498
- Redwood can absorb more carbon
- than any other tree variety on the planet.
- 395
- 00:36:49,025 --> 00:36:56,441
- Through their needles, the trees absorb carbon
- from the carbon dioxide in the air.
- 396
- 00:36:56,491 --> 00:37:02,739
- Then the coal is stored in the trunk,
- roots and branches.
- 397
- 00:37:02,789 --> 00:37:08,227
- As far as I know, this is here
- one of the country's largest coal projects.
- 398
- 00:37:15,593 --> 00:37:20,239
- I am a bio fertilizer project manager
- at the Redwood Forest Foundation.
- 399
- 00:37:21,182 --> 00:37:24,886
- We have great concerns
- here in California-
- 400
- 00:37:24,936 --> 00:37:29,098
- - with over a hundred million dead trees.
- 401
- 00:37:29,148 --> 00:37:31,625
- We have to do something about it.
- 402
- 00:37:33,319 --> 00:37:36,606
- Here is a beetle called
- Western Pine Bark Beetle
- 403
- 00:37:36,656 --> 00:37:42,636
- - who are living on chewing themselves
- yellow and also other trees.
- 404
- 00:37:43,329 --> 00:37:45,865
- They have been here for thousands of years
- 405
- 00:37:45,915 --> 00:37:49,869
- - and have lived in harmony with the trees.
- 406
- 00:37:49,919 --> 00:37:53,498
- But because of climate change
- and the prolonged drought
- 407
- 00:37:53,548 --> 00:37:56,042
- - has millions of trees
- become very weak
- 408
- 00:37:56,992 --> 00:38:00,546
- - and has difficulty defending
- against the beetle.
- 409
- 00:38:00,596 --> 00:38:05,676
- Bio fertilizer can be a way to
- attack the problem of beetles
- 410
- 00:38:05,726 --> 00:38:08,763
- - and the dying trees
- in Sierra Nevada.
- 411
- 00:38:08,813 --> 00:38:14,644
- Bio-fertilizer is a form of coal
- which is useful in farming
- 412
- 00:38:14,694 --> 00:38:18,214
- -and gives a more prosperous soil.
- 413
- 00:38:21,242 --> 00:38:24,362
- When dry distilling the wood biomass
- 414
- 00:38:24,412 --> 00:38:31,602
- - half of the coal can
- The biomass is recovered as residual waste.
- 415
- 00:38:32,295 --> 00:38:39,001
- The biomass helps the soil through
- to bind nutrients and water.
- 416
- 00:38:39,551 --> 00:38:43,381
- It's more like a kind of construction
- who incubates life.
- 417
- 00:38:43,431 --> 00:38:46,426
- Almost half are used
- of all the coal in the plant
- 418
- 00:38:46,476 --> 00:38:49,887
- - which will be better
- use in cultivated soil.
- 419
- 00:38:49,937 --> 00:38:52,974
- It is of enormous benefit
- for agriculture.
- 420
- 00:38:53,024 --> 00:38:56,477
- We have large amounts of biomass
- need to be used.
- 421
- 00:38:56,527 --> 00:39:02,942
- The trees constitute a fire hazard
- while the fires are raging in California.
- 422
- 00:39:02,992 --> 00:39:06,863
- By producing bio fertilizer
- can we bring back some of the material
- 423
- 00:39:06,913 --> 00:39:09,073
- - to the forests safely.
- 424
- 00:39:09,123 --> 00:39:16,539
- Or we use the biomass
- in the valley, where water is really needed.
- 425
- 00:39:16,589 --> 00:39:23,838
- One of the benefits of bio fertilizer is
- that it binds water in the soil.
- 426
- 00:39:23,888 --> 00:39:28,092
- If we added biofertilizer in
- ten percent of the world's cultivation soil
- 427
- 00:39:28,142 --> 00:39:33,473
- - we should isolate
- 29 billion tons of CO2.
- 428
- 00:39:33,523 --> 00:39:38,019
- 29 billion tons with ten percent.
- And just by using
- 429
- 00:39:38,669 --> 00:39:43,090
- - "leftover residual material".
- It is significant.
- 430
- 00:39:44,992 --> 00:39:48,071
- Then we have the climate compensations.
- 431
- 00:39:48,121 --> 00:39:51,866
- For us to get them
- we must employ multiple
- 432
- 00:39:51,916 --> 00:39:55,828
- - who works with the forest
- and can attest to the clients
- 433
- 00:39:55,878 --> 00:39:59,916
- - that the coal we say we have
- actually there
- 434
- 00:39:59,966 --> 00:40:02,752
- -and stays here in the future.
- 435
- 00:40:02,802 --> 00:40:06,214
- I like to see ourselves as an example
- who can inspire others
- 436
- 00:40:06,264 --> 00:40:08,508
- - to do the same as we do.
- 437
- 00:40:08,558 --> 00:40:10,468
- This is not rocket research.
- 438
- 00:40:10,518 --> 00:40:14,722
- Carbon storage becomes
- huge in the future.
- 439
- 00:40:14,772 --> 00:40:19,310
- We need more and bigger forests.
- 440
- 00:40:19,360 --> 00:40:25,424
- Forests that should never be felled
- and remain forever.
- 441
- 00:40:42,133 --> 00:40:46,170
- My name is Kate Scow and I am a professor
- in land-air and water resources-
- 442
- 00:40:46,220 --> 00:40:48,423
- - at the University of California, Davis.
- 443
- 00:40:48,473 --> 00:40:51,092
- I am also an earth microbial ecologist.
- 444
- 00:40:51,142 --> 00:40:58,182
- The carbon cycle globally involves
- both water and terrestrial systems.
- 445
- 00:40:58,232 --> 00:41:03,337
- Soil is an important part
- of the terrestrial system.
- 446
- 00:41:04,655 --> 00:41:10,194
- Soil contains 2-3 times more carbon
- compared to the atmosphere.
- 447
- 00:41:10,244 --> 00:41:15,116
- The earth is the place there
- crops grow best.
- 448
- 00:41:15,166 --> 00:41:22,248
- That means that everything that grows
- binds CO2 via photosynthesis
- 449
- 00:41:22,298 --> 00:41:27,920
- - and miraculously creates a physical
- mass here on earth from air.
- 450
- 00:41:27,970 --> 00:41:30,114
- It still fascinates me.
- 451
- 00:41:31,557 --> 00:41:36,971
- The process captures coal,
- the plant binds CO2, it dies
- 452
- 00:41:37,021 --> 00:41:43,644
- - the plant falls to the ground and
- becomes part of the carbon cycle.
- 453
- 00:41:43,694 --> 00:41:49,859
- There is much more coal
- bound in the soil than in the atmosphere.
- 454
- 00:41:49,909 --> 00:41:56,491
- Organic farms do not produce any
- nutrients from artificial manure.
- 455
- 00:41:56,541 --> 00:42:01,204
- The manure consists of organic material.
- 456
- 00:42:01,254 --> 00:42:04,165
- It can be medium crops
- or compost
- 457
- 00:42:04,215 --> 00:42:10,129
- - as food, plant or animal remnants
- as you plow into the earth.
- 458
- 00:42:10,179 --> 00:42:13,216
- In an organic farming system
- can you add-
- 459
- 00:42:13,266 --> 00:42:19,097
- - eight times as much coal
- compared to a regular system.
- 460
- 00:42:19,147 --> 00:42:23,876
- It's really quite simple.
- 461
- 00:42:25,945 --> 00:42:30,066
- Climate change
- gives us the chance
- 462
- 00:42:30,116 --> 00:42:34,445
- - to change our behavior
- on this planet.
- 463
- 00:42:34,495 --> 00:42:39,826
- We know what we are capable of
- in the worst case, so now the question is ...
- 464
- 00:42:39,876 --> 00:42:47,108
- If we deliberately want to be
- part of the healing process ...
- 465
- 00:42:49,635 --> 00:42:54,073
- ... it can release our creativity.
- 466
- 00:42:55,516 --> 00:42:58,970
- Then maybe you realize
- that you have a garden.
- 467
- 00:42:59,020 --> 00:43:03,541
- "Oh my God,"
- I have a park nearby.
- 468
- 00:43:04,567 --> 00:43:11,215
- We should see ourselves as we
- helping to save the planet ...
- 469
- 00:43:13,201 --> 00:43:18,389
- It is much better than seeing us
- like nasty little children with matches.
- 470
- 00:43:19,290 --> 00:43:26,205
- Then you realize that we are all
- small pieces of the solution.
- 471
- 00:43:26,255 --> 00:43:29,751
- Now we send directly
- from my mentor's house.
- 472
- 00:43:29,801 --> 00:43:33,212
- The organic gardener
- Ron Finley.
- 473
- 00:43:33,262 --> 00:43:37,091
- I always want to come here
- and learn different ways -
- 474
- 00:43:37,141 --> 00:43:42,638
- - to use the small soil
- I have and grow as much as I can.
- 475
- 00:43:42,688 --> 00:43:46,225
- Culinary climate measures
- is what I want to see.
- 476
- 00:43:46,275 --> 00:43:50,396
- What I grow sucks out
- coal from the atmosphere.
- 477
- 00:43:50,446 --> 00:43:56,635
- It shows that we can return it
- back into the earth again.
- 478
- 00:43:58,371 --> 00:44:03,201
- It creates both green jobs
- and counteracts problems that-
- 479
- 00:44:03,251 --> 00:44:06,704
- - diabetes and obesity
- in the area where I live.
- 480
- 00:44:06,754 --> 00:44:11,793
- There are many plots
- and plenty of water available.
- 481
- 00:44:11,843 --> 00:44:15,254
- It's for a good cause
- and gives a nice result.
- 482
- 00:44:15,304 --> 00:44:20,176
- We pull out the toxins from the atmosphere
- 483
- 00:44:20,226 --> 00:44:23,388
- - which we ourselves have released.
- 484
- 00:44:23,438 --> 00:44:27,183
- Best way to transform them
- is to grow something edible.
- 485
- 00:44:27,233 --> 00:44:29,502
- Grow on the roof, grow in the window.
- 486
- 00:44:30,778 --> 00:44:32,814
- We know how it gets warmer.
- 487
- 00:44:32,864 --> 00:44:36,651
- A farmer must have faith in the future.
- No doomsday mentality.
- 488
- 00:44:36,701 --> 00:44:41,197
- You have to plant, water
- and believe that it will be a harvest.
- 489
- 00:44:41,247 --> 00:44:45,785
- That is the discussion I want to see
- when we talk about changing the climate.
- 490
- 00:44:45,835 --> 00:44:51,065
- It doesn't happen overnight,
- But we must start now. It's time.
- 491
- 00:45:12,737 --> 00:45:16,816
- My name is Bren Smith
- and runs Thimble Island Ocean Farm.
- 492
- 00:45:16,866 --> 00:45:21,571
- We are in the Thimble Islands
- in the Long Islands Sound.
- 493
- 00:45:21,621 --> 00:45:24,323
- I grew up in
- Newfoundland in Canada-
- 494
- 00:45:24,373 --> 00:45:27,744
- - jumped off the plug
- and have fished all over the planet.
- 495
- 00:45:27,794 --> 00:45:29,662
- In Gloucester in Newfoundland
- 496
- 00:45:29,712 --> 00:45:32,415
- - Then I worked
- on the Bering Sea for many years.
- 497
- 00:45:32,465 --> 00:45:35,543
- Then the industrialized fishery went
- at high speed.
- 498
- 00:45:35,593 --> 00:45:38,796
- We tore up whole ecosystems
- with our trawlers
- 499
- 00:45:38,846 --> 00:45:42,050
- - and chased less and less fish
- all the way out to sea.
- 500
- 00:45:42,100 --> 00:45:44,177
- It was completely unsustainable.
- 501
- 00:45:44,227 --> 00:45:49,457
- Much of the fish I pulled up
- would be food at McDonald's.
- 502
- 00:45:50,858 --> 00:45:54,729
- It was an alarm clock
- for many from my generation.
- 503
- 00:45:54,779 --> 00:45:58,399
- I was out on the Bering Sea
- when the cod market crashed.
- 504
- 00:45:58,449 --> 00:46:02,737
- Thousands of people became unemployed,
- factories were beaten again.
- 505
- 00:46:02,787 --> 00:46:07,241
- It taught me that you can build
- a culture for several hundred years
- 506
- 00:46:07,291 --> 00:46:09,410
- - But if you don't
- protects resources
- 507
- 00:46:09,460 --> 00:46:13,689
- - can collapse the ecosystem
- delete everything in a few years.
- 508
- 00:46:15,425 --> 00:46:19,921
- That was when we began to realize
- that problems like overfishing
- 509
- 00:46:19,971 --> 00:46:23,466
- - and climate change
- are not environmental issues
- 510
- 00:46:23,516 --> 00:46:26,761
- - for us who work at sea.
- They are financial problems.
- 511
- 00:46:26,811 --> 00:46:29,830
- There is neither food nor jobs
- on a dead planet.
- 512
- 00:46:32,024 --> 00:46:36,938
- When I realized it was unsustainable
- I began to look for sustainability.
- 513
- 00:46:36,988 --> 00:46:39,524
- I retrained myself to oyster fishermen.
- 514
- 00:46:39,574 --> 00:46:43,778
- The oysters taught me that nature
- have created constructions-
- 515
- 00:46:43,828 --> 00:46:47,115
- - millions of years ago
- which alleviates our harmful effects.
- 516
- 00:46:47,165 --> 00:46:51,911
- We do not need advanced technology.
- Nature gives us seaweed and seafood
- 517
- 00:46:51,961 --> 00:46:55,206
- - that binds five times more carbon
- than terrestrial plants.
- 518
- 00:46:55,256 --> 00:47:00,294
- An oyster filters 189 liters of water
- per day, which removes nitrogen.
- 519
- 00:47:00,344 --> 00:47:02,880
- My job as the ocean's chieftain
- 520
- 00:47:02,930 --> 00:47:06,217
- - is to take advantage of nature's
- constructions and cultivate them.
- 521
- 00:47:06,267 --> 00:47:08,428
- It's pretty simple.
- 522
- 00:47:08,478 --> 00:47:14,809
- It's great to grow restoration
- species is that nothing is required.
- 523
- 00:47:14,859 --> 00:47:20,690
- No fresh water, no food,
- no manure and no land.
- 524
- 00:47:20,740 --> 00:47:23,926
- It is the most sustainable
- food production on earth.
- 525
- 00:47:25,703 --> 00:47:29,032
- Kelp is this beautiful seagrass.
- 526
- 00:47:29,882 --> 00:47:34,287
- The gateway to the new kitchen.
- One of the fastest growing plants
- 527
- 00:47:34,337 --> 00:47:37,498
- - and sucks up five times more carbon
- than terrestrial plants.
- 528
- 00:47:37,548 --> 00:47:40,043
- It's called Sea Sequoia.
- 529
- 00:47:40,933 --> 00:47:46,674
- Kelp is just the beginning. There is
- 10,000 edible plants in the seas.
- 530
- 00:47:46,724 --> 00:47:49,802
- Parts of the plant
- we can make kelp noodles.
- 531
- 00:47:49,852 --> 00:47:56,351
- Then this can be
- manure and animal feed.
- 532
- 00:47:56,401 --> 00:48:02,732
- If cows eat seaweed feed decreases
- methane emissions by 90 percent.
- 533
- 00:48:02,782 --> 00:48:07,945
- Still, cows, sheep and goats have
- eaten kelp for hundreds of years.
- 534
- 00:48:07,995 --> 00:48:10,573
- On the Hebrides, in Maine
- and elsewhere.
- 535
- 00:48:10,623 --> 00:48:15,495
- There are incredible volumes. We can
- produce 20 tons of kelp per acre
- 536
- 00:48:15,545 --> 00:48:20,500
- - and 150,000 seafood.
- Imagine this in larger scale
- 537
- 00:48:20,550 --> 00:48:24,504
- - to an area of Washington state.
- Then you can give the whole world food.
- 538
- 00:48:24,554 --> 00:48:29,217
- Take five percent of US
- territorial waters and
- 539
- 00:48:29,267 --> 00:48:31,594
- - 50 million new jobs are created
- 540
- 00:48:31,644 --> 00:48:36,624
- - and coal equivalent
- 20 million cars are bound.
- 541
- 00:48:38,109 --> 00:48:41,020
- Our crops also soften
- acidification of the oceans.
- 542
- 00:48:41,070 --> 00:48:44,190
- Kelp creates a so-called halo effect
- 543
- 00:48:44,240 --> 00:48:50,446
- - which reduces acidification.
- Then oysters and other seafood
- 544
- 00:48:50,496 --> 00:48:56,477
- - easier to get thicker shells
- which protects better against acidification.
- 545
- 00:48:57,503 --> 00:49:03,501
- Some said that climate change
- would take a hundred years.
- 546
- 00:49:03,551 --> 00:49:05,086
- But it happens here and now.
- 547
- 00:49:05,136 --> 00:49:09,132
- As a fisherman we are lucky to be able to
- move to something similar.
- 548
- 00:49:09,182 --> 00:49:12,760
- I'm proud to help
- to arrange food for my country.
- 549
- 00:49:12,810 --> 00:49:19,083
- Maybe I'm part of that army
- who will save the planet.
- 550
- 00:49:30,661 --> 00:49:36,242
- If we send out ten large units
- CO2 in the atmosphere.
- 551
- 00:49:36,292 --> 00:49:38,494
- -And about stay there.
- 552
- 00:49:38,544 --> 00:49:43,041
- 2.5 of them end up in plants
- and 2.5 ports in the sea.
- 553
- 00:49:43,091 --> 00:49:47,128
- If the sea is acidified,
- what do you do about it?
- 554
- 00:49:47,178 --> 00:49:51,758
- Nature takes care of the problem
- by making more seafood.
- 555
- 00:49:51,808 --> 00:49:56,387
- It is the theory of marine snow,
- that small animals grow in the water
- 556
- 00:49:56,437 --> 00:49:59,766
- - They have calcium shells
- falling down.
- 557
- 00:49:59,816 --> 00:50:05,772
- The problem is that the planet wants it
- a perspective of millions of years.
- 558
- 00:50:05,822 --> 00:50:08,066
- We don't.
- 559
- 00:50:08,116 --> 00:50:12,636
- So the question is if you can
- speed up the process?
- 560
- 00:50:17,542 --> 00:50:20,703
- We need to examine all options.
- 561
- 00:50:20,753 --> 00:50:25,249
- There is more experimental
- hypotheses that need to be tested.
- 562
- 00:50:25,299 --> 00:50:32,948
- A solution can be found in it
- microscopic life cycle marine snow.
- 563
- 00:50:34,225 --> 00:50:37,178
- What do we need?
- 564
- 00:50:37,228 --> 00:50:40,890
- We need this planet
- as it was before.
- 565
- 00:50:40,940 --> 00:50:45,520
- We must regain it in that condition
- It was 200 years ago.
- 566
- 00:50:45,570 --> 00:50:51,359
- Higher levels of CO2
- increases the acidification of the oceans.
- 567
- 00:50:51,409 --> 00:50:56,739
- The garden then loses its ability
- to suck up coal from the atmosphere.
- 568
- 00:50:56,789 --> 00:50:59,617
- We have to do something about it.
- 569
- 00:50:59,667 --> 00:51:05,164
- We must help those systems
- circulating carbon
- 570
- 00:51:05,214 --> 00:51:11,963
- - between the atmosphere,
- the plants on land and seas.
- 571
- 00:51:12,013 --> 00:51:18,619
- And with marine snow
- just need some help from us.
- 572
- 00:51:19,353 --> 00:51:26,144
- The most important thing is to remove CO2
- and produce oxygen.
- 573
- 00:51:26,194 --> 00:51:31,941
- What we can do is
- to add minimal amounts
- 574
- 00:51:31,991 --> 00:51:36,404
- - iron in the seas. Very little.
- 575
- 00:51:36,454 --> 00:51:41,325
- It has nothing to do
- with the term fertilizer.
- 576
- 00:51:41,375 --> 00:51:46,205
- To give you an idea
- just need six kilos of iron
- 577
- 00:51:46,255 --> 00:51:52,295
- - to start the process in
- 100,000 square kilometers of the sea.
- 578
- 00:51:52,345 --> 00:51:55,381
- The cells create
- an organic parent tissue
- 579
- 00:51:55,431 --> 00:52:01,512
- - Which is why
- the design of marine snow.
- 580
- 00:52:01,562 --> 00:52:05,099
- When the mother tissue arises-
- 581
- 00:52:05,149 --> 00:52:10,063
- - it attracts cyanobacteria
- and heterotrophic bacteria
- 582
- 00:52:10,113 --> 00:52:14,008
- - which colonizes the particles
- and then actively growing.
- 583
- 00:52:15,118 --> 00:52:18,112
- Then we let them take care of themselves -
- 584
- 00:52:18,162 --> 00:52:24,660
- - Because they can take
- very long time.
- 585
- 00:52:24,710 --> 00:52:29,356
- We can trace the marine snow particles
- for more than four months.
- 586
- 00:52:30,049 --> 00:52:34,128
- They can float around and
- suck organic matter
- 587
- 00:52:34,178 --> 00:52:40,075
- - and when they get too heavy
- they sink to the bottom of the sea.
- 588
- 00:52:42,228 --> 00:52:48,226
- Speed of change,
- increased levels and temperatures
- 589
- 00:52:48,276 --> 00:52:51,979
- - make sure we have to act while we can.
- 590
- 00:52:52,229 --> 00:52:57,652
- I'm absolutely sure
- that we can succeed with ...
- 591
- 00:52:57,702 --> 00:53:05,142
- ... to get man to cooperate
- with nature, do not oppose it.
- 592
- 00:53:14,427 --> 00:53:19,340
- Science has long been proven
- that we have technology that works.
- 593
- 00:53:19,390 --> 00:53:22,176
- -and that it's already used.
- 594
- 00:53:22,226 --> 00:53:26,139
- It's just a matter of
- political will and size.
- 595
- 00:53:26,189 --> 00:53:31,269
- We need a lot of solutions
- going forward in parallel.
- 596
- 00:53:31,319 --> 00:53:33,521
- To solve the crisis
- 597
- 00:53:33,571 --> 00:53:38,843
- - We need to move on
- one hundred percent renewable energy now.
- 598
- 00:53:39,577 --> 00:53:46,225
- Of the top five solutions ended up
- coastal wind power in second place.
- 599
- 00:53:47,543 --> 00:53:52,874
- COASTAL WIND POWER PLANT
- ORKNEY ISLANDS, SCOTLAND
- 600
- 00:53:52,924 --> 00:53:59,447
- Wind power is more efficient than solar power,
- which was a surprise.
- 601
- 00:54:03,601 --> 00:54:07,913
- Solar power will be in place eight out of ten.
- 602
- 00:54:11,609 --> 00:54:17,398
- The sun is the largest resource we have.
- Everything else fades in comparison.
- 603
- 00:54:17,448 --> 00:54:20,568
- We've known that for a long time,
- but we have never been able to
- 604
- 00:54:20,618 --> 00:54:23,905
- - extract it economically.
- It has changed now.
- 605
- 00:54:23,955 --> 00:54:28,659
- Solar energy is already cheaper
- than fossil fuels.
- 606
- 00:54:28,709 --> 00:54:33,373
- Already installed in the 80s
- Jimmy Carter solar cells at the White House.
- 607
- 00:54:33,423 --> 00:54:35,875
- Then Reagan took them away.
- 608
- 00:54:35,925 --> 00:54:42,131
- Not until 2001, when Germany
- started with solar energy in larger scale
- 609
- 00:54:42,181 --> 00:54:45,927
- - we could start to benefit from
- economy in large scale.
- 610
- 00:54:45,977 --> 00:54:52,517
- In the end, we can provide the whole
- electricity grid with solar and wind power.
- 611
- 00:54:52,567 --> 00:54:57,463
- We just need it
- be able to store wind and sun.
- 612
- 00:54:59,157 --> 00:55:02,735
- If you want to cater for the whole
- US electricity demand with solar cell alone
- 613
- 00:55:02,785 --> 00:55:06,114
- - we would need a surface on
- 77,700 square kilometers.
- 614
- 00:55:06,164 --> 00:55:12,728
- The energy from there would suffice
- electricity networks in all states throughout the United States.
- 615
- 00:55:15,173 --> 00:55:19,752
- Mount Signal is a project that provides
- electricity to 70,000 households in San Diego.
- 616
- 00:55:19,802 --> 00:55:25,574
- The second phase of the energy will
- sent to Southern California.
- 617
- 00:55:27,018 --> 00:55:32,849
- The cost of electricity from Mount Signal
- is lower than electricity from fossil fuels.
- 618
- 00:55:32,899 --> 00:55:38,421
- The cost is also
- safe for use.
- 619
- 00:55:39,238 --> 00:55:42,608
- The price is fixed
- the next 25 years.
- 620
- 00:55:42,658 --> 00:55:47,972
- It is not offered
- from fossil energy sources.
- 621
- 00:55:48,664 --> 00:55:51,951
- We have already integrated
- much solar power in California.
- 622
- 00:55:52,001 --> 00:55:54,662
- Ten years ago, people said
- that it was impossible-
- 623
- 00:55:54,712 --> 00:56:00,543
- - but today solar energy already covers
- up to 25% of California's needs.
- 624
- 00:56:00,593 --> 00:56:06,174
- Taxpayers got none
- increased costs and everything works.
- 625
- 00:56:06,224 --> 00:56:10,286
- And we got reduced
- carbon emissions in the purchase.
- 626
- 00:56:15,483 --> 00:56:20,355
- Lately, state works
- offered to buy solar cells.
- 627
- 00:56:20,405 --> 00:56:23,566
- The attitude is changing.
- 628
- 00:56:23,616 --> 00:56:27,070
- We still underestimate
- the value of solar cells.
- 629
- 00:56:27,120 --> 00:56:32,658
- People do not know that in five years
- are the solar cells much cheaper-
- 630
- 00:56:32,708 --> 00:56:35,661
- -and can be used at night.
- 631
- 00:56:35,711 --> 00:56:37,872
- In combination with wind power
- 632
- 00:56:37,922 --> 00:56:41,417
- - we can live in an environment with
- 100 percent renewable energy.
- 633
- 00:56:41,467 --> 00:56:46,422
- It is fully feasible.
- No new inventions are required.
- 634
- 00:56:46,472 --> 00:56:48,341
- We already have the technology.
- 635
- 00:56:48,391 --> 00:56:53,346
- We just have to make sure
- that those responsible for
- 636
- 00:56:53,396 --> 00:56:57,100
- - planning of
- resource use and infrastructure
- 637
- 00:56:57,150 --> 00:57:03,923
- - Understands this technology
- becomes cheaper over time.
- 638
- 00:57:08,244 --> 00:57:13,783
- The coal is coming back.
- Clean coal, 100 percent.
- 639
- 00:57:13,833 --> 00:57:18,162
- My government is stopping
- for the war against the coal.
- 640
- 00:57:18,212 --> 00:57:22,858
- We should have clean coal. Really clean.
- 641
- 00:57:24,719 --> 00:57:27,255
- Think Progress:
- Clean energy employs multiple
- 642
- 00:57:27,305 --> 00:57:30,783
- - than fossil fuels do,
- in almost all states
- 643
- 00:57:32,018 --> 00:57:33,511
- The Independent:
- 644
- 00:57:33,561 --> 00:57:37,390
- World-leading carbon company closes
- 37 mines when solar prices fall
- 645
- 00:57:37,440 --> 00:57:39,583
- Fossil producers under pressure
- 646
- 00:57:41,486 --> 00:57:46,357
- Solar energy beats its own record
- with the cheapest electricity-
- 647
- 00:57:46,407 --> 00:57:51,029
- - "compared with
- all other technologies ever "
- 648
- 00:57:51,779 --> 00:57:54,657
- It can be difficult to communicate
- science to the public.
- 649
- 00:57:54,707 --> 00:57:57,452
- Today, we assume the challenge
- 650
- 00:57:57,502 --> 00:58:03,124
- - and adds an extra
- effort behind.
- 651
- 00:58:03,174 --> 00:58:07,003
- Interest groups funded
- of fossil fuel operators
- 652
- 00:58:07,553 --> 00:58:09,630
- -designs climate discussion-
- 653
- 00:58:09,680 --> 00:58:13,009
- - to confuse the public
- and the decision makers.
- 654
- 00:58:13,559 --> 00:58:15,261
- We must transform the entire energy sector -
- 655
- 00:58:15,311 --> 00:58:18,973
- - quit fossil fuels
- and switch to renewable energy.
- 656
- 00:58:19,023 --> 00:58:24,020
- But it gets pretty awkward
- for the powerful fossil industry
- 657
- 00:58:24,070 --> 00:58:29,233
- - who have invested millions of dollars
- in creating a dependency on them.
- 658
- 00:58:29,283 --> 00:58:32,528
- They have struggled hard
- to maintain that dependency.
- 661
- 00:58:45,341 --> 00:58:48,294
- We are often asked how we can know
- 662
- 00:58:48,344 --> 00:58:52,298
- - that the increased CO2 level in the atmosphere
- depends on human activity.
- 663
- 00:58:52,348 --> 00:58:57,203
- The answer is that we leave climate footprints
- after us, around the atmosphere.
- 664
- 00:58:58,771 --> 00:59:05,436
- One such imprint is called carbon-14,
- or radioactive carbon.
- 665
- 00:59:05,486 --> 00:59:11,109
- When we burn coal, oil and gas
- we leave an imprint in the atmosphere
- 666
- 00:59:11,159 --> 00:59:15,947
- -of what we call negative carbon-14.
- 667
- 00:59:15,997 --> 00:59:20,451
- Because fossil fuels are so old
- there is no carbon 14 left anymore.
- 668
- 00:59:20,501 --> 00:59:25,456
- We can specify the quantity with precision
- fossil fuels we consume
- 669
- 00:59:25,506 --> 00:59:27,917
- - by measuring C-14 in the atmosphere.
- 670
- 00:59:27,967 --> 00:59:33,322
- It is nature's own verification
- systems we use.
- 671
- 00:59:36,350 --> 00:59:40,888
- They have convinced enough
- and have enough
- 672
- 00:59:40,938 --> 00:59:45,643
- - to make it even more difficult
- than it was before
- 673
- 00:59:45,693 --> 00:59:49,272
- - to address climate change.
- It's so depressing.
- 674
- 00:59:49,322 --> 00:59:55,653
- The agenda of many of them
- fossil fuel companies
- 675
- 00:59:55,703 --> 01:00:01,034
- - is malicious in view of
- the devastation that affects our planet.
- 677
- 01:00:08,466 --> 01:00:12,754
- I think parts of it
- well-financed climate denial
- 678
- 01:00:12,804 --> 01:00:15,631
- - performed by people
- who really know better-
- 679
- 01:00:15,681 --> 01:00:20,703
- - is a crime against humanity.
- They should be brought to justice in The Hague.
- 680
- 01:00:29,153 --> 01:00:32,940
- While the climate deniers
- has managed to delay the action -
- 681
- 01:00:32,990 --> 01:00:36,319
- - has a lot more ominous
- problem appeared.
- 682
- 01:00:36,369 --> 01:00:43,368
- Recently, researchers have seen elevated levels
- levels of methane in the atmosphere.
- 683
- 01:00:43,418 --> 01:00:46,788
- Methane is a powerful greenhouse gas
- 684
- 01:00:46,838 --> 01:00:50,958
- - with the potential to enhance
- further temperatures.
- 685
- 01:00:51,008 --> 01:00:56,089
- An increase in methane suggests
- that we are approaching a critical point.
- 686
- 01:00:56,139 --> 01:00:58,132
- But where does the gas come from?
- 687
- 01:00:58,182 --> 01:01:02,512
- And how much does it accelerate
- climate disruption?
- 688
- 01:01:02,562 --> 01:01:05,289
- The researchers are stressing
- to find out.
- 689
- 01:01:11,362 --> 01:01:15,817
- This is the University of Wyomings
- mobile laboratory.
- 690
- 01:01:15,867 --> 01:01:21,989
- Here are instruments that measure
- what is in the air we breathe now.
- 691
- 01:01:22,039 --> 01:01:27,912
- That way we can track
- emissions and gases
- 692
- 01:01:27,962 --> 01:01:31,999
- - and find out
- were the sources of the emissions
- 693
- 01:01:32,049 --> 01:01:35,653
- - And what leads to
- elevated methane levels.
- 694
- 01:01:38,181 --> 01:01:40,466
- Inside the lab
- There are a couple of instruments.
- 695
- 01:01:40,516 --> 01:01:44,220
- Here is a Proton Transfer Reaction
- Time of Flight Mass Spec.
- 696
- 01:01:44,270 --> 01:01:48,307
- It measures volatile organic matter
- such as benzene and toluene.
- 697
- 01:01:48,357 --> 01:01:53,563
- Here is a Picarro Cavity Ring-Down
- that measures the methane concentration.
- 698
- 01:01:53,613 --> 01:01:57,775
- We can read all the data
- from real-time instruments
- 699
- 01:01:57,825 --> 01:02:04,240
- - thanks to an intake on top of the car
- that draws in air to the instruments.
- 700
- 01:02:04,290 --> 01:02:09,912
- After the measurements we arrived
- that we have more methane sources
- 701
- 01:02:09,962 --> 01:02:14,500
- - in areas where we extract the gas,
- than we had expected.
- 702
- 01:02:14,550 --> 01:02:17,795
- To be able to specify
- where the methane leaks are-
- 703
- 01:02:17,845 --> 01:02:20,798
- - one must be near the sources.
- 704
- 01:02:20,848 --> 01:02:26,120
- The mobile lab helps us
- to locate the largest leaks.
- 705
- 01:02:27,647 --> 01:02:31,059
- The company has opened
- a brand new facility.
- 706
- 01:02:31,109 --> 01:02:36,898
- 22 new gas sources have been drilled
- in the middle of the settlement in Western Greeley.
- 707
- 01:02:36,948 --> 01:02:41,385
- The facility has been controversial,
- regarding size and location.
- 708
- 01:02:46,374 --> 01:02:52,622
- It is said that society does not have
- been able to keep up with what is going on there.
- 709
- 01:02:52,672 --> 01:02:55,375
- A high sound level surrounds the business-
- 710
- 01:02:55,425 --> 01:03:01,172
- - And the state probably doesn't do its best
- to facilitate communication.
- 711
- 01:03:01,222 --> 01:03:06,511
- We saw a lot of flames,
- which indicates large volumes of gas.
- 712
- 01:03:06,561 --> 01:03:11,349
- The yellow color of the flame shows
- that it is not full combustion.
- 713
- 01:03:11,399 --> 01:03:15,311
- We shall continue to investigate the sources
- 715
- 01:03:20,074 --> 01:03:24,612
- Some oil and gas producing
- regions have such a large
- 716
- 01:03:24,662 --> 01:03:28,825
- - concentration of methane in the air
- that it is visible from space.
- 717
- 01:03:28,875 --> 01:03:34,080
- It happened a few years ago
- in the region of the four corners.
- 718
- 01:03:34,130 --> 01:03:38,376
- That's the key for us
- when to find out
- 720
- 01:03:53,524 --> 01:03:59,731
- In 2014, NASA researchers identified
- in collaboration with NOAA-
- 721
- 01:03:59,781 --> 01:04:03,151
- - University of Michigan
- and other researchers
- 722
- 01:04:03,201 --> 01:04:08,197
- - a methane cloud like Delaware
- in the region of the four corners.
- 723
- 01:04:08,247 --> 01:04:14,871
- It is the largest accumulation
- methane gas throughout the United States.
- 724
- 01:04:14,921 --> 01:04:19,876
- This ranch, where we are now,
- is the approximate zero point.
- 725
- 01:04:19,926 --> 01:04:26,007
- If you could find the midpoint
- on the Delaware-shaped cloud
- 726
- 01:04:26,557 --> 01:04:28,426
- - It would very well
- be here.
- 727
- 01:04:28,476 --> 01:04:32,930
- One has been identified
- that the cause of methane cloud
- 728
- 01:04:32,980 --> 01:04:38,728
- - mainly emissions
- in connection with drilling
- 729
- 01:04:38,778 --> 01:04:43,340
- - as well as emissions from coal
- and other fossil fuels.
- 730
- 01:04:45,368 --> 01:04:51,991
- The methane cloud was identified by
- the technology that NOAA and NASA had
- 731
- 01:04:52,041 --> 01:04:54,994
- - due
- FLIR camera arrival.
- 732
- 01:04:55,044 --> 01:05:01,167
- There are infrared cameras that look
- leaks, emissions and flames
- 733
- 01:05:01,217 --> 01:05:03,753
- - which causes the methane cloud to grow.
- 734
- 01:05:03,803 --> 01:05:10,134
- You have to see the whole picture.
- It has been at least 60 years
- 735
- 01:05:10,184 --> 01:05:17,308
- - of leaks, emissions and burning
- here in the San Jaun sink.
- 736
- 01:05:17,358 --> 01:05:23,815
- Over 30,000 sources
- has got methane cloud
- 737
- 01:05:23,865 --> 01:05:27,694
- - to accumulate
- and provide evidence for
- 738
- 01:05:27,744 --> 01:05:33,032
- - what drilling for natural gas
- leads to ultimately.
- 739
- 01:05:33,082 --> 01:05:38,496
- People do not know common sources
- has created methane cloud
- 740
- 01:05:38,546 --> 01:05:42,024
- - and that they themselves daily
- have been accomplices.
- 741
- 01:05:46,512 --> 01:05:51,718
- This is a common gas source.
- This equipment is available
- 742
- 01:05:51,768 --> 01:05:55,930
- - throughout the San Juan sink
- and on many other gas fields in the United States.
- 743
- 01:05:55,980 --> 01:06:00,351
- This leaks considerably from the standard
- parts on it.
- 744
- 01:06:00,401 --> 01:06:06,816
- All that is needed here is
- a wrench and a little teflon tape.
- 745
- 01:06:06,866 --> 01:06:09,318
- A little review would fix the leak.
- 746
- 01:06:09,368 --> 01:06:16,784
- I wish I could ask
- investors in gas and oil here
- 747
- 01:06:16,834 --> 01:06:20,288
- - where I stand
- and let them see that leak.
- 748
- 01:06:20,338 --> 01:06:24,292
- Let them multiply it
- with 18,000 in the San Juan sink
- 749
- 01:06:24,342 --> 01:06:28,546
- - and make them stop obstructing
- a federal rule
- 750
- 01:06:28,596 --> 01:06:32,550
- - protect my family,
- protect taxpayers in New Mexico
- 751
- 01:06:32,600 --> 01:06:37,680
- - and offer fair and equal
- protection in all states.
- 752
- 01:06:37,730 --> 01:06:42,185
- Get them out of the boardroom
- and come here-
- 753
- 01:06:42,235 --> 01:06:45,938
- - and let them look at the leak
- which is so easy to cook.
- 754
- 01:06:45,988 --> 01:06:50,276
- When I was told
- that environmental manager Scott Pruitt-
- 755
- 01:06:50,326 --> 01:06:54,030
- - knew that there were facts
- 756
- 01:06:54,080 --> 01:06:57,700
- - that strengthened methane and
- other leaking chemicals
- 757
- 01:06:57,750 --> 01:07:01,788
- - are more harmful to children
- than they are for me.
- 758
- 01:07:01,838 --> 01:07:08,544
- Then I became so angry that he wanted
- prevent federal protection for us.
- 759
- 01:07:08,594 --> 01:07:15,218
- If anyone came to my ranch
- with intent to harm my child
- 760
- 01:07:15,268 --> 01:07:17,995
- -It would be over my dead body.
- 761
- 01:07:31,492 --> 01:07:38,324
- 250 million years ago became one
- secondary effect of methane emissions
- 762
- 01:07:38,374 --> 01:07:42,912
- - that much of life
- on the ground died out.
- 763
- 01:07:42,962 --> 01:07:46,249
- Now it is discussed around
- the methane found in the Arctic
- 764
- 01:07:46,299 --> 01:07:50,378
- - in the permafrost or in the sea of the world.
- 765
- 01:07:50,428 --> 01:07:57,868
- How fast can methane be mobilized
- and how destructive it becomes?
- 766
- 01:07:58,603 --> 01:08:04,767
- Release of ancient methane
- can lead to even more warming.
- 767
- 01:08:04,817 --> 01:08:08,730
- Will the methane be created
- an apocalyptic scenario?
- 768
- 01:08:08,780 --> 01:08:13,651
- It's a question that researchers have
- desperately trying to answer.
- 769
- 01:08:13,701 --> 01:08:18,531
- I am the head of the Center for Gas
- Hydrate, Environment & Climate.
- 770
- 01:08:18,581 --> 01:08:23,036
- We are a team with 50-60 researchers
- who works to understand us-
- 771
- 01:08:23,086 --> 01:08:27,498
- - what impact methane has on
- the global climate system.
- 772
- 01:08:27,548 --> 01:08:33,838
- Methane is stored below
- The bottom of the Arctic Ocean
- 773
- 01:08:33,888 --> 01:08:38,926
- - in places we sometimes know,
- but we usually don't know much about them.
- 774
- 01:08:38,976 --> 01:08:45,975
- We apply geophysical methods
- to quantify the reservoirs
- 775
- 01:08:46,025 --> 01:08:51,797
- - and to see how stable
- The methane hydrates are today and later.
- 777
- 01:08:57,912 --> 01:09:01,532
- Fortunately, methane has a short lifetime.
- 778
- 01:09:01,582 --> 01:09:07,455
- The earth has a natural system
- which regulates the supply of methane
- 779
- 01:09:07,505 --> 01:09:10,291
- -from the garden and out into the atmosphere.
- 780
- 01:09:10,341 --> 01:09:13,169
- The system works quite well
- 781
- 01:09:13,219 --> 01:09:17,673
- - but it changes,
- because the ocean currents change
- 782
- 01:09:17,723 --> 01:09:22,762
- - just like the garden temperature
- and the garden chemistry is changing.
- 783
- 01:09:22,812 --> 01:09:26,808
- The methane was
- in a kind of equilibrium mode
- 784
- 01:09:26,858 --> 01:09:32,438
- - but in recent years
- we have seen a large increase in methane.
- 785
- 01:09:32,488 --> 01:09:35,274
- We don't know where it comes from.
- 786
- 01:09:35,324 --> 01:09:40,780
- Of course it puts it
- pressure on science
- 787
- 01:09:40,830 --> 01:09:45,868
- - to give politicians an answer regarding
- methane in the atmosphere.
- 788
- 01:09:45,918 --> 01:09:51,874
- Where does the methane come from?
- What else becomes unstable at present?
- 789
- 01:09:51,924 --> 01:09:56,421
- We have presented some clear
- campaigns where we have measured
- 790
- 01:09:56,471 --> 01:10:02,844
- - by the seabed, in the sea,
- at the sea surface and in the air,
- 791
- 01:10:02,894 --> 01:10:08,433
- - to understand how methane is regulated
- throughout the system.
- 792
- 01:10:08,483 --> 01:10:11,394
- There is a lot
- methane stored in the seabed.
- 793
- 01:10:11,444 --> 01:10:16,107
- So much to the slightest change
- can have an impact
- 794
- 01:10:16,157 --> 01:10:20,028
- - on the ocean or the atmosphere.
- 795
- 01:10:20,078 --> 01:10:22,488
- META MEASUREMENTS
- IN NORWAY ISHAVET
- 796
- 01:10:22,538 --> 01:10:26,909
- The balance here needs more focus
- and more observations-
- 797
- 01:10:26,959 --> 01:10:33,524
- - where you combine atmospheric,
- sea and climate competence.
- 798
- 01:10:35,635 --> 01:10:41,424
- In my profession I study
- how methane seeps into the sea
- 799
- 01:10:41,474 --> 01:10:44,218
- -In the Russian Sea and in the Barents Sea.
- 800
- 01:10:44,268 --> 01:10:47,680
- It is simply gas bubbles
- rising from the seabed.
- 801
- 01:10:47,730 --> 01:10:52,310
- The bubbles consist mostly of methane gas.
- 802
- 01:10:52,360 --> 01:10:58,507
- First we have gas hydrates
- which is in solid form and similar to ice.
- 803
- 01:10:59,909 --> 01:11:04,305
- The gas is also available in free form,
- which becomes gas bubbles.
- 804
- 01:11:05,081 --> 01:11:07,533
- The plumes of methane bubbles may vary.
- 805
- 01:11:07,583 --> 01:11:14,023
- In some places
- they can be 800-900 meters long.
- 806
- 01:11:15,716 --> 01:11:19,337
- Depth in these areas
- is just over 1,200 meters.
- 807
- 01:11:19,387 --> 01:11:25,051
- In shallower water reaches
- the bubbles almost up to the surface.
- 808
- 01:11:25,101 --> 01:11:29,555
- The East Siberian Sea is definitely
- interesting when studying methane
- 809
- 01:11:29,605 --> 01:11:31,599
- -As it is so shallow there.
- 810
- 01:11:31,649 --> 01:11:37,355
- There is a great chance to
- the methane bubbles reach the surface.
- 811
- 01:11:37,405 --> 01:11:44,595
- In some areas, such as Spetsbergen,
- There is methane that almost reaches the surface.
- 812
- 01:11:50,877 --> 01:11:53,830
- We've warmed up the atmosphere
- so much -
- 813
- 01:11:53,880 --> 01:11:57,441
- -We've started melting the Arctic.
- 814
- 01:11:58,134 --> 01:12:03,297
- Potentially, we are facing
- an abrupt climate scenario.
- 815
- 01:12:03,347 --> 01:12:07,844
- Today's calculations show that we
- passes the Paris agreement with raw
- 816
- 01:12:07,894 --> 01:12:10,430
- up to five degrees and more.
- 817
- 01:12:10,480 --> 01:12:16,227
- It triggers even more
- disastrous events.
- 818
- 01:12:16,277 --> 01:12:21,607
- The heating can lead to big ones
- supplement of methane in the atmosphere.
- 819
- 01:12:21,657 --> 01:12:25,528
- It should really worry us.
- 820
- 01:12:25,578 --> 01:12:29,824
- I want to add that it is one
- of many possible stressors.
- 821
- 01:12:29,874 --> 01:12:35,204
- We are approaching a high-risk
- situation where we lack experience.
- 822
- 01:12:35,254 --> 01:12:39,066
- We don't know how
- should deal with it.
- 823
- 01:12:43,971 --> 01:12:45,465
- PERMAFROST:
- 824
- 01:12:45,515 --> 01:12:52,288
- Land that has been constantly frozen
- and containing methane and CO2
- 825
- 01:13:00,154 --> 01:13:04,942
- Permafrost and methane
- are great concerns.
- 826
- 01:13:04,992 --> 01:13:11,699
- I think we should
- be more attentive
- 827
- 01:13:11,749 --> 01:13:16,270
- - on methane in general,
- in relation to the climate problems.
- 829
- 01:13:24,554 --> 01:13:28,007
- The risk is that you
- passing the breakpoint
- 830
- 01:13:28,057 --> 01:13:33,496
- - where it then becomes difficult
- reverse the trend.
- 831
- 01:13:39,694 --> 01:13:42,730
- PERMAFROST AREA
- ALASKA
- 832
- 01:13:42,780 --> 01:13:45,733
- There is a perfectly reasonable one
- feedback mechanism.
- 833
- 01:13:45,783 --> 01:13:52,323
- There are huge amounts in the permafrost
- organic matter frozen.
- 834
- 01:13:52,373 --> 01:13:57,912
- The amount potentially
- can become CO2 and methane
- 835
- 01:13:57,962 --> 01:14:05,194
- - can be four times bigger than everything
- fossil fuel we have consumed.
- 836
- 01:14:08,681 --> 01:14:11,759
- 30,000 year old methane
- bubbles up from a frozen lake
- 837
- 01:14:11,809 --> 01:14:16,180
- If we thaw up
- all frozen material
- 838
- 01:14:16,230 --> 01:14:22,895
- - the most likely emission of CO2 occurs
- and methane gas in large scale
- 840
- 01:14:29,702 --> 01:14:32,947
- I study methane emissions from lakes.
- 841
- 01:14:32,997 --> 01:14:39,353
- We are in inner Alaska where we have
- discontinuous permafrost.
- 842
- 01:14:40,171 --> 01:14:42,915
- We look at microbial methane.
- 843
- 01:14:42,965 --> 01:14:48,087
- The methane that bubbles behind me
- comes from dead plants and animal
- 844
- 01:14:48,137 --> 01:14:51,966
- - which was frozen into the permafrost
- tens of thousands of years ago.
- 845
- 01:14:52,016 --> 01:14:54,010
- As the permafrost tinar-
- 846
- 01:14:54,060 --> 01:14:59,623
- - Eat the microbes in the soil
- and make it methane.
- 847
- 01:15:01,025 --> 01:15:07,732
- The thawing permafrost
- fire on methane production.
- 848
- 01:15:07,782 --> 01:15:10,818
- Then the methane disappears
- up in the atmosphere
- 851
- 01:15:18,584 --> 01:15:23,081
- What worries us is
- that as the climate gets warmer-
- 852
- 01:15:23,131 --> 01:15:26,751
- - at a faster pace
- than the last 10,000 years
- 854
- 01:15:30,763 --> 01:15:34,300
- - and let go
- methane gas faster.
- 856
- 01:15:38,896 --> 01:15:41,682
- Highly concentrated methane
- is flammable
- 857
- 01:15:41,732 --> 01:15:44,769
- - So if it's a flame
- it is methane.
- 859
- 01:15:52,493 --> 01:15:58,408
- Many new lakes have been formed as not
- existed here 30 or 60 years ago.
- 860
- 01:15:58,458 --> 01:16:04,939
- The lakes contain 10-100 times
- more methane than the other lakes.
- 861
- 01:16:05,715 --> 01:16:09,919
- They give a picture of the methane emissions
- as we can expect-
- 862
- 01:16:09,969 --> 01:16:16,634
- - the next 10 to 50 years
- as the permafrost thaws.
- 863
- 01:16:16,684 --> 01:16:21,622
- Then comes the permafrost feedback cycle
- and it accelerates even more.
- 864
- 01:16:23,524 --> 01:16:26,978
- Is it methane? Is it permafrost?
- 865
- 01:16:27,028 --> 01:16:31,816
- Is it the organic coal in the seas
- who suddenly move again?
- 867
- 01:16:35,578 --> 01:16:41,659
- You have to ask about it
- is there feedback in the system?
- 868
- 01:16:41,709 --> 01:16:43,953
- The answer is yes.
- 869
- 01:16:44,003 --> 01:16:47,623
- It is usually common sense
- 870
- 01:16:47,673 --> 01:16:51,694
- - that the less you disturb the climate,
- The better it will be.
- 871
- 01:17:03,898 --> 01:17:09,354
- We have the solutions ready,
- but the question still remains.
- 872
- 01:17:09,404 --> 01:17:14,925
- We can mobilize and act
- collectively before it is late?
- 873
- 01:17:15,618 --> 01:17:18,554
- The will to do so
- is not really there.
- 874
- 01:17:19,747 --> 01:17:24,994
- The Paris Agreement says
- that we must reduce carbon emissions
- 875
- 01:17:25,044 --> 01:17:28,664
- - and keep the temperature
- below a certain level
- 876
- 01:17:28,714 --> 01:17:32,860
- - Although we won't
- to do that.
- 877
- 01:17:34,011 --> 01:17:40,201
- What can save us is technology
- that sucks CO2 out of the atmosphere.
- 878
- 01:17:41,561 --> 01:17:47,725
- Then you should bet
- all the resources of humanity-
- 879
- 01:17:47,775 --> 01:17:51,670
- - to develop CO2 purification methods
- which works.
- 880
- 01:17:53,114 --> 01:17:58,010
- Then we can save the world,
- So why don't we?
- 881
- 01:18:06,085 --> 01:18:09,622
- CLIMEWORKS
- GET IN CO2 FROM THE AIR
- 882
- 01:18:09,672 --> 01:18:15,461
- Direct Air Capture is machines
- which removes CO2 from the air.
- 883
- 01:18:15,511 --> 01:18:18,840
- We have worked with
- technology over the past ten years -
- 885
- 01:18:22,643 --> 01:18:25,221
- -and as economical as possible.
- 886
- 01:18:25,271 --> 01:18:31,769
- The machine consists of four containers
- and can have any size whatsoever.
- 887
- 01:18:31,819 --> 01:18:34,046
- Here the air is sucked in ...
- 888
- 01:18:34,822 --> 01:18:38,426
- ... and inside there is
- our filter construction.
- 890
- 01:18:44,582 --> 01:18:48,703
- When CO2 is captured
- ends up in a greenhouse.
- 893
- 01:18:55,218 --> 01:18:59,088
- Similar is happening nowadays,
- solid with fossil CO2.
- 894
- 01:18:59,138 --> 01:19:02,575
- In the future they will come
- to use atmospheric CO2.
- 895
- 01:19:06,145 --> 01:19:09,057
- The facility does
- that you can stop the carbon cycle.
- 896
- 01:19:09,107 --> 01:19:14,479
- The CO2 that gets into the greenhouse
- also ends up in cucumbers and tomatoes
- 898
- 01:19:17,657 --> 01:19:21,527
- But because we capture CO2 again
- the circle is closed.
- 899
- 01:19:21,577 --> 01:19:25,406
- This can be
- the missing cake bit -
- 900
- 01:19:25,456 --> 01:19:31,771
- - needed to stop the carbon cycle
- in the energy or transport sector.
- 901
- 01:19:35,007 --> 01:19:38,336
- In addition to using CO2
- in a greenhouse like this
- 902
- 01:19:38,386 --> 01:19:42,840
- - can we take CO2,
- water and renewable energy
- 903
- 01:19:42,890 --> 01:19:47,286
- - and of it produce fuel,
- for example, aviation fuel.
- 904
- 01:19:47,979 --> 01:19:51,974
- To capture one percent
- of the global CO2 emissions
- 905
- 01:19:52,024 --> 01:19:55,770
- - about 300,000 needed
- of the plants behind me
- 906
- 01:19:55,820 --> 01:19:58,064
- -Which is a very high figure.
- 907
- 01:19:58,114 --> 01:20:00,942
- But compared to today's
- the infrastructures
- 908
- 01:20:00,992 --> 01:20:07,223
- - it is an extent that we can handle,
- so it is definitely possible.
- 909
- 01:20:09,375 --> 01:20:12,495
- Hellisheidi power plant for
- geothermal energy in Iceland
- 910
- 01:20:12,545 --> 01:20:16,207
- The next project is
- a plant in Iceland-
- 912
- 01:20:22,680 --> 01:20:26,926
- Two hours later you do
- CO2 to a stone
- 913
- 01:20:26,976 --> 01:20:31,247
- - that keeps it permanently
- and safely.
- 914
- 01:20:33,274 --> 01:20:37,795
- To operate the plant
- we use geothermal heat.
- 915
- 01:20:38,821 --> 01:20:41,107
- It is abundant in Iceland.
- 916
- 01:20:41,157 --> 01:20:46,362
- It hardly gives any carbon footprint
- to operate the machinery.
- 917
- 01:20:46,412 --> 01:20:52,618
- It's a great day. We have received
- The CO2 plant to Iceland.
- 918
- 01:20:52,668 --> 01:20:57,123
- We pull CO2 out of the air,
- pumps it down underground
- 919
- 01:20:57,173 --> 01:21:01,377
- - and store it in the rock below us,
- where the carbon dioxide is bound.
- 920
- 01:21:01,427 --> 01:21:06,716
- So we take CO2 from the air
- and turn it into stone.
- 921
- 01:21:06,766 --> 01:21:13,139
- Last night was the first time that
- atmospheric CO2 was introduced into the ground.
- 922
- 01:21:13,189 --> 01:21:19,145
- We can come up
- in millions of tons of CO2 per year
- 923
- 01:21:19,195 --> 01:21:21,773
- - which can be extracted from the atmosphere.
- 924
- 01:21:21,823 --> 01:21:25,068
- As far as we know it is
- the first time in the world-
- 925
- 01:21:25,118 --> 01:21:28,404
- - as direct capture of CO2
- has been combined with
- 926
- 01:21:28,454 --> 01:21:32,308
- - with underground, safe and
- permanent storage of CO2.
- 927
- 01:21:35,795 --> 01:21:39,040
- We have a new relationship with coal.
- 928
- 01:21:39,090 --> 01:21:42,335
- Can't find us
- a new use for it?
- 929
- 01:21:42,385 --> 01:21:46,214
- Can't we have it
- in plastic or building materials?
- 930
- 01:21:46,264 --> 01:21:51,786
- We may be able to convert carbon dioxide
- to something we need every day?
- 931
- 01:22:00,194 --> 01:22:07,360
- A LOW LIGHT UP THE WAY
- 932
- 01:22:07,410 --> 01:22:12,949
- My name is Daniel Nocera and I am
- professor of energy at Harvard.
- 933
- 01:22:12,999 --> 01:22:19,122
- In the lab we invented the artificial
- and the bionic leaf.
- 934
- 01:22:19,172 --> 01:22:24,127
- They can perform
- a complete photosynthesis.
- 935
- 01:22:24,177 --> 01:22:29,115
- Sunlight, air and water
- they convert into fuel and food.
- 936
- 01:22:30,224 --> 01:22:32,969
- Think about photosynthesis.
- 937
- 01:22:33,019 --> 01:22:38,307
- What is it doing?
- It makes life's building blocks.
- 938
- 01:22:38,357 --> 01:22:44,897
- The building blocks are CO2,
- water and sunlight.
- 939
- 01:22:44,947 --> 01:22:48,067
- Then we build all this.
- 940
- 01:22:48,117 --> 01:22:53,364
- Wood, food, starch and biomass.
- 941
- 01:22:53,414 --> 01:22:56,826
- It's an incredible transformation.
- 942
- 01:22:56,876 --> 01:23:02,957
- Photosynthesis is complicated,
- but we really listened to nature.
- 943
- 01:23:03,007 --> 01:23:06,377
- And we did that for 30 years.
- 944
- 01:23:06,427 --> 01:23:09,130
- What makes me so happy-
- 945
- 01:23:09,180 --> 01:23:12,258
- - is that we are not just
- can make it artificially-
- 946
- 01:23:12,308 --> 01:23:16,220
- - but also ten times better
- than the real photosynthesis.
- 947
- 01:23:16,270 --> 01:23:20,391
- We developed catalysts
- that covered the artificial leaf.
- 948
- 01:23:20,441 --> 01:23:24,312
- They split the water
- in hydrogen and oxygen.
- 949
- 01:23:24,362 --> 01:23:27,815
- The second part of the invention
- is the bionic leaf.
- 950
- 01:23:27,865 --> 01:23:33,071
- It takes nitrogen from bacteria
- and manufactures fuel.
- 951
- 01:23:33,121 --> 01:23:37,408
- Depending on the genes
- i put into the bacterium
- 952
- 01:23:37,458 --> 01:23:41,788
- - I can get the bacterium
- to manufacture materials, medicines
- 953
- 01:23:41,838 --> 01:23:44,624
- - and we've shown
- that they can make fertilizers.
- 954
- 01:23:44,674 --> 01:23:51,672
- We can use all kinds of water.
- Plain water, sea water ...
- 955
- 01:23:51,722 --> 01:23:56,135
- You only have my artificial leaves
- one can do it in the garden.
- 956
- 01:23:56,185 --> 01:24:01,307
- We don't have to dig it up like that
- are there and release more CO2.
- 957
- 01:24:01,357 --> 01:24:04,394
- The artificial leaf
- in collaboration with the bionic
- 958
- 01:24:04,444 --> 01:24:09,065
- - takes CO2 out of the air and uses
- sun and water to make fuel.
- 959
- 01:24:09,115 --> 01:24:14,529
- So we don't add any more
- CO2 to the atmosphere.
- 960
- 01:24:14,579 --> 01:24:18,533
- Another thing is the cost.
- 961
- 01:24:18,583 --> 01:24:24,622
- I-countries have added fantasy sums
- to build what they have today.
- 962
- 01:24:24,672 --> 01:24:30,086
- It is difficult to abandon one billion
- investment that you have paid off.
- 963
- 01:24:30,136 --> 01:24:32,004
- That's what it's all about.
- 964
- 01:24:32,054 --> 01:24:36,784
- Therefore, guidelines are required
- and good collaborations.
- 965
- 01:24:37,477 --> 01:24:42,807
- And that the public gets to know
- that they have alternative
- 966
- 01:24:42,857 --> 01:24:46,585
- -and that the world can change.
- 968
- 01:24:55,828 --> 01:25:01,492
- The green economy creates
- already millions of jobs.
- 969
- 01:25:01,542 --> 01:25:06,998
- It will surpass the economy
- from the fossil fuel industry.
- 970
- 01:25:07,048 --> 01:25:13,296
- The challenge to reverse the climate crisis
- provides new opportunities for everyone.
- 971
- 01:25:13,346 --> 01:25:18,451
- It's now more profitable
- than ever to be green.
- 972
- 01:25:21,354 --> 01:25:27,560
- Until recently, more was earned
- to create problems
- 973
- 01:25:27,610 --> 01:25:31,773
- - even coming up with solutions.
- 974
- 01:25:31,823 --> 01:25:36,944
- The solutions therefore required
- subsidies that hardly existed.
- 975
- 01:25:36,994 --> 01:25:40,281
- The alternatives were altruism or belief.
- 977
- 01:25:44,794 --> 01:25:50,166
- Then a transition took place where the profit
- from the solutions became bigger-
- 978
- 01:25:50,216 --> 01:25:54,796
- - than the benefits of the problems,
- which is not so easy to understand.
- 979
- 01:25:54,846 --> 01:25:58,591
- It does not mean altruism
- Not needed, it's something great.
- 980
- 01:25:58,641 --> 01:26:03,763
- But altruism will not be required
- to take the step towards a world-
- 981
- 01:26:03,813 --> 01:26:09,018
- - where we turn the heating,
- because it is cheaper.
- 982
- 01:26:09,068 --> 01:26:12,480
- It's more profitable, more affordable
- and creates more jobs.
- 983
- 01:26:12,530 --> 01:26:16,567
- It's the most amazing
- which has happened for several years.
- 984
- 01:26:16,617 --> 01:26:20,405
- And it will only grow
- as the years go by
- 985
- 01:26:20,455 --> 01:26:22,907
- - Because engineers
- and designers
- 986
- 01:26:22,957 --> 01:26:28,413
- - which are largely unknown,
- works diligently to develop
- 987
- 01:26:28,463 --> 01:26:34,819
- - a new way for man
- to relate to the planet.
- 988
- 01:26:44,896 --> 01:26:52,503
- ORKNEY ISLANDS
- SCOTLAND
- 989
- 01:26:53,446 --> 01:26:57,150
- Here at Orkney we have
- a very strong maritime tradition.
- 990
- 01:26:57,200 --> 01:27:01,237
- Ever since the 70's has
- the oil and gas industry in Aberdeen
- 991
- 01:27:01,287 --> 01:27:05,742
- - been important to the economy
- and created tens of thousands of jobs.
- 992
- 01:27:05,792 --> 01:27:08,703
- But in recent years we have seen
- a large turnaround
- 993
- 01:27:08,753 --> 01:27:12,123
- - concerning the oil and gas industry
- and the oil price.
- 994
- 01:27:12,173 --> 01:27:17,462
- But we have many experienced people
- from offshore jobs on the way in.
- 995
- 01:27:17,512 --> 01:27:20,173
- They find new jobs
- within renewable energy
- 996
- 01:27:20,223 --> 01:27:22,283
- -hos company like us.
- 997
- 01:27:25,394 --> 01:27:29,390
- Tides are almost
- a completely unused energy source.
- 998
- 01:27:29,440 --> 01:27:34,854
- We believe we have the potential to achieve
- a capacity of at least 100 gigawatts.
- 999
- 01:27:34,904 --> 01:27:41,844
- That means low-carbon energy
- to millions of households.
- 1000
- 01:27:43,079 --> 01:27:48,242
- Here we see the world's most powerful,
- floating tidal generator.
- 1001
- 01:27:48,292 --> 01:27:53,230
- It is a floating platform
- with two fixed rotors.
- 1002
- 01:27:57,218 --> 01:28:01,047
- When the rotors spin
- electricity is produced
- 1003
- 01:28:01,097 --> 01:28:04,217
- - brought up to the machine,
- where it is conditioned.
- 1004
- 01:28:04,267 --> 01:28:11,265
- Then the electricity is transformed
- and carried out into the power grid.
- 1005
- 01:28:11,315 --> 01:28:15,878
- It's like a wind turbine,
- fixed with two rotors instead of one.
- 1006
- 01:28:17,113 --> 01:28:19,941
- A few weeks ago
- we made great progress.
- 1007
- 01:28:19,991 --> 01:28:24,070
- We had our first 24 hours
- with uninterrupted electricity production.
- 1008
- 01:28:24,120 --> 01:28:27,365
- It actually worked
- far better than expected.
- 1009
- 01:28:27,415 --> 01:28:33,287
- The device itself generated over
- 18 megawatt hours during the day.
- 1010
- 01:28:33,337 --> 01:28:38,209
- We are moving towards more traditional ones
- methods in renewable energy.
- 1011
- 01:28:38,259 --> 01:28:42,547
- We put the tide on the map as
- a competitive alternative
- 1012
- 01:28:42,597 --> 01:28:45,574
- - Worldwide,
- and the world needs.
- 1013
- 01:28:47,518 --> 01:28:51,139
- The turbine is 63 meters in total.
- 1014
- 01:28:51,189 --> 01:28:54,726
- We convert the energy on board
- so that it is completely clear-
- 1015
- 01:28:54,776 --> 01:28:58,021
- - to be exported straight out
- in the UK electricity grid.
- 1016
- 01:28:58,071 --> 01:29:04,193
- We aim for
- tens of thousands of tidal turbines.
- 1017
- 01:29:04,243 --> 01:29:06,237
- It's a complete system
- 1018
- 01:29:06,287 --> 01:29:08,973
- - for production
- of low carbon energy.
- 1019
- 01:29:12,085 --> 01:29:15,038
- EMEC was built as a test lab
- 1020
- 01:29:15,088 --> 01:29:20,543
- - because we know there are huge
- amounts of energy in the world's oceans.
- 1021
- 01:29:20,593 --> 01:29:23,171
- We try to find a way
- to extract it.
- 1022
- 01:29:23,221 --> 01:29:27,300
- We realized that it was important
- to have a test center
- 1023
- 01:29:27,350 --> 01:29:30,470
- - where we could find out
- how this would happen.
- 1024
- 01:29:30,520 --> 01:29:35,058
- From the test center we have cables
- leading straight to the sea
- 1025
- 01:29:35,108 --> 01:29:40,229
- - like the developers of the machines
- can connect.
- 1026
- 01:29:40,279 --> 01:29:42,673
- Then the electricity is brought in
- 1027
- 01:29:43,783 --> 01:29:46,486
- - and straight out
- in our national electricity grid.
- 1028
- 01:29:46,536 --> 01:29:50,806
- They create electricity from seawater.
- 1029
- 01:29:51,916 --> 01:29:56,496
- Now we have the Penguin device here,
- made by the company Wello Oy.
- 1030
- 01:29:56,546 --> 01:30:01,334
- Their machine basically consists of
- a large pendulum inside the ship.
- 1031
- 01:30:01,384 --> 01:30:04,712
- As the ship moves
- spins the pendulum horizontally.
- 1032
- 01:30:04,762 --> 01:30:06,756
- It generates energy.
- 1033
- 01:30:06,806 --> 01:30:10,593
- The sea is ruthless and
- always trying to damage the equipment
- 1034
- 01:30:10,643 --> 01:30:15,473
- - so to bring out equipment that is
- reliable, robust, efficient, profitable ...
- 1035
- 01:30:15,523 --> 01:30:17,767
- All the developers wrestle with that.
- 1036
- 01:30:17,817 --> 01:30:21,062
- But we have already managed to create gold.
- 1037
- 01:30:21,112 --> 01:30:23,898
- We've actually transformed
- sea water for energy.
- 1038
- 01:30:23,948 --> 01:30:27,944
- It's huge, because people
- has questioned it for years.
- 1040
- 01:30:55,271 --> 01:30:58,850
- No one can claim that the researchers
- have not warned us-
- 1041
- 01:30:58,900 --> 01:31:03,187
- - and said that we must reduce
- greenhouse gas emissions.
- 1042
- 01:31:03,237 --> 01:31:04,939
- It should be crystal clear.
- 1043
- 01:31:04,989 --> 01:31:07,734
- How many breakpoints can we pass-
- 1045
- 01:31:13,164 --> 01:31:18,703
- - or that most of life
- on the planet does not manage?
- 1046
- 01:31:18,753 --> 01:31:23,207
- It must not go so far.
- And we're so fucking close now.
- 1047
- 01:31:23,257 --> 01:31:29,005
- Either we hold the course
- and drowning, burning up
- 1048
- 01:31:29,055 --> 01:31:32,675
- - and starve to death
- as a result of the climate crisis.
- 1051
- 01:31:40,942 --> 01:31:43,561
- Or has the game just begun?
- 1052
- 01:31:43,611 --> 01:31:50,151
- After all, we have the knowledge and solutions that
- can turn global warming.
- 1053
- 01:31:50,201 --> 01:31:54,489
- Don't mitigate or reduce it.
- We can turn it around.
- 1054
- 01:31:54,539 --> 01:31:57,784
- When setting high goals
- new opportunities are opened.
- 1055
- 01:31:57,834 --> 01:32:01,662
- It opens the imagination
- and opens for innovations.
- 1056
- 01:32:01,712 --> 01:32:04,749
- It does not exclude anything,
- rather the opposite.
- 1057
- 01:32:04,799 --> 01:32:08,002
- It's not that it exists
- a single solution
- 1058
- 01:32:08,052 --> 01:32:15,134
- - but in collaboration one can achieve
- results with 80% of the solutions.
- 1059
- 01:32:15,184 --> 01:32:20,848
- Each solution has great advantages
- that makes the world better for everyone.
- 1060
- 01:32:20,898 --> 01:32:27,063
- We lose nothing to realize
- that climate change is going on-
- 1061
- 01:32:27,113 --> 01:32:31,383
- - and that we are affected.
- So what's the problem?
- 1062
- 01:32:37,749 --> 01:32:42,370
- We are the first generation
- who see climate change -
- 1063
- 01:32:42,420 --> 01:32:45,873
- - and the last one
- with a chance to fix it.
- 1064
- 01:32:45,923 --> 01:32:47,834
- Despite all the evidence
- 1065
- 01:32:47,884 --> 01:32:53,047
- - fossil fuels are still used
- at an ever increasing rate.
- 1066
- 01:32:53,097 --> 01:32:59,804
- Science has given us the truth,
- based on real research.
- 1067
- 01:32:59,854 --> 01:33:06,936
- It's time to start listening and
- apply the solutions available.
- 1068
- 01:33:06,986 --> 01:33:11,524
- Time is out soon. Ice melts.
- 1069
- 01:33:11,574 --> 01:33:18,031
- Resolution measures must be taken now.
- There is no other option.
- 1070
- 01:33:18,081 --> 01:33:23,661
- The opportunity is within our reach.
- Now we take it.
- 1071
- 01:33:23,711 --> 01:33:26,998
- It's up to each of us -
- 1072
- 01:33:27,048 --> 01:33:32,778
- - to save our unique blue planet
- for future generations.
