Last year I showed these two slides so that
0
0
3000
00:15
demonstrate that the arctic ice cap,
1
3000
2000
00:17
which for most of the last three million years
2
5000
2000
00:19
has been the size of the lower 48 states,
3
7000
2000
00:21
has shrunk by 40 percent.
4
9000
2000
00:23
But this understates the seriousness of this particular problem
5
11000
3000
00:26
because it doesn't show the thickness of the ice.
6
14000
3000
00:29
The arctic ice cap is, in a sense,
7
17000
2000
00:31
the beating heart of the global climate system.
8
19000
3000
00:34
It expands in winter and contracts in summer.
9
22000
3000
00:37
The next slide I show you will be
10
25000
3000
00:40
a rapid fast-forward of what's happened over the last 25 years.
11
28000
4000
00:44
The permanent ice is marked in red.
12
32000
2000
00:46
As you see, it expands to the dark blue --
13
34000
3000
00:49
that's the annual ice in winter,
14
37000
2000
00:51
and it contracts in summer.
15
39000
2000
00:53
The so-called permanent ice, five years old or older,
16
41000
2000
00:55
you can see is almost like blood,
17
43000
3000
00:58
spilling out of the body here.
18
46000
4000
01:02
In 25 years it's gone from this, to this.
19
50000
4000
01:06
This is a problem because the warming
20
54000
3000
01:09
heats up the frozen ground around the Arctic Ocean,
21
57000
3000
01:12
where there is a massive amount of frozen carbon
22
60000
3000
01:15
which, when it thaws, is turned into methane by microbes.
23
63000
3000
01:18
Compared to the total amount of global warming pollution in the atmosphere,
24
66000
4000
01:22
that amount could double if we cross this tipping point.
25
70000
4000
01:26
Already in some shallow lakes in Alaska,
26
74000
3000
01:29
methane is actively bubbling up out of the water.
27
77000
2000
01:31
Professor Katey Walter from the University of Alaska
28
79000
3000
01:34
went out with another team to another shallow lake last winter.
29
82000
4000
01:48
Video: Whoa! (Laughter)
30
96000
2000
01:50
Al Gore: She's okay. The question is whether we will be.
31
98000
3000
01:53
And one reason is, this enormous heat sink
32
101000
2000
01:55
heats up Greenland from the north.
33
103000
3000
01:58
This is an annual melting river.
34
106000
3000
02:01
But the volumes are much larger than ever.
35
109000
3000
02:04
This is the Kangerlussuaq River in southwest Greenland.
36
112000
3000
02:07
If you want to know how sea level rises
37
115000
2000
02:09
from land-base ice melting
38
117000
2000
02:11
this is where it reaches the sea.
39
119000
2000
02:13
These flows are increasing very rapidly.
40
121000
2000
02:15
At the other end of the planet, Antarctica
41
123000
2000
02:17
the largest mass of ice on the planet.
42
125000
2000
02:19
Last month scientists reported the entire continent
43
127000
2000
02:21
is now in negative ice balance.
44
129000
2000
02:23
And west Antarctica cropped up on top some under-sea islands,
45
131000
4000
02:27
is particularly rapid in its melting.
46
135000
3000
02:30
That's equal to 20 feet of sea level, as is Greenland.
47
138000
4000
02:34
In the Himalayas, the third largest mass of ice:
48
142000
2000
02:36
at the top you see new lakes, which a few years ago were glaciers.
49
144000
4000
02:40
40 percent of all the people in the world
50
148000
2000
02:42
get half of their drinking water from that melting flow.
51
150000
2000
02:44
In the Andes, this glacier is the
52
152000
2000
02:46
source of drinking water for this city.
53
154000
2000
02:48
The flows have increased.
54
156000
2000
02:50
But when they go away, so does much of the drinking water.
55
158000
3000
02:53
In California there has been a 40 percent
56
161000
2000
02:55
decline in the Sierra snowpack.
57
163000
2000
02:57
This is hitting the reservoirs.
58
165000
2000
02:59
And the predictions, as you've read, are serious.
59
167000
3000
03:02
This drying around the world has lead to
60
170000
2000
03:04
a dramatic increase in fires.
61
172000
2000
03:06
And the disasters around the world
62
174000
3000
03:09
have been increasing at an absolutely extraordinary
63
177000
2000
03:11
and unprecedented rate.
64
179000
2000
03:13
Four times as many in the last 30 years
65
181000
2000
03:15
as in the previous 75.
66
183000
2000
03:17
This is a completely unsustainable pattern.
67
185000
4000
03:21
If you look at in the context of history
68
189000
3000
03:24
you can see what this is doing.
69
192000
5000
03:29
In the last five years
70
197000
2000
03:31
we've added 70 million tons of CO2
71
199000
2000
03:33
every 24 hours --
72
201000
2000
03:35
25 million tons every day to the oceans.
73
203000
2000
03:37
Look carefully at the area of the eastern Pacific,
74
205000
3000
03:40
from the Americas, extending westward,
75
208000
2000
03:42
and on either side of the Indian subcontinent,
76
210000
3000
03:45
where there is a radical depletion of oxygen in the oceans.
77
213000
4000
03:49
The biggest single cause of global warming,
78
217000
2000
03:51
along with deforestation, which is 20 percent of it, is the burning of fossil fuels.
79
219000
4000
03:55
Oil is a problem, and coal is the most serious problem.
80
223000
3000
03:58
The United States is one of the two
81
226000
2000
04:00
largest emitters, along with China.
82
228000
2000
04:02
And the proposal has been to build a lot more coal plants.
83
230000
4000
04:06
But we're beginning to see a sea change.
84
234000
2000
04:08
Here are the ones that have been cancelled in the last few years
85
236000
3000
04:11
with some green alternatives proposed.
86
239000
2000
04:13
(Applause)
87
241000
1000
04:14
However there is a political battle
88
242000
3000
04:17
in our country.
89
245000
2000
04:19
And the coal industries and the oil industries
90
247000
2000
04:21
spent a quarter of a billion dollars in the last calendar year
91
249000
3000
04:24
promoting clean coal,
92
252000
2000
04:26
which is an oxymoron.
93
254000
2000
04:28
That image reminded me of something.
94
256000
2000
04:30
(Laughter)
95
258000
3000
04:33
Around Christmas, in my home in Tennessee,
96
261000
2000
04:35
a billion gallons of coal sludge was spilled.
97
263000
3000
04:38
You probably saw it on the news.
98
266000
2000
04:40
This, all over the country, is the second largest waste stream in America.
99
268000
4000
04:44
This happened around Christmas.
100
272000
2000
04:46
One of the coal industry's ads around Christmas was this one.
101
274000
3000
04:49
Video: ♪♫ Frosty the coal man is a jolly, happy soul.
102
277000
3000
04:52
He's abundant here in America,
103
280000
2000
04:54
and he helps our economy grow.
104
282000
2000
04:56
Frosty the coal man is getting cleaner everyday.
105
284000
4000
05:00
He's affordable and adorable, and workers keep their pay.
106
288000
4000
05:04
Al Gore: This is the source of much of the coal in West Virginia.
107
292000
4000
05:08
The largest mountaintop miner is the head of Massey Coal.
108

Video: Don Blankenship: Let me be clear about it. Al Gore,
109
301000
2000
05:15
Nancy Pelosi, Harry Reid, they don't know what they're talking about.
110
303000
4000
05:19
Al Gore: So the Alliance for Climate Protection
111
307000
2000
05:21
has launched two campaigns.
112
309000
2000
05:23
This is one of them, part of one of them.
113
311000
3000
05:26
Video: Actor: At COALergy we view climate change as a very serious
114
314000
2000
05:28
threat to our business.
115
316000
2000
05:30
That's why we've made it our primary goal
116
318000
2000
05:32
to spend a large sum of money
117
320000
2000
05:34
on an advertising effort to help bring out and complicate
118
322000
3000
05:37
the truth about coal.
119
325000
2000
05:39
The fact is, coal isn't dirty.
120
327000
2000
05:41
We think it's clean --
121
329000
2000
05:43
smells good, too.
122
331000
2000
05:45
So don't worry about climate change.
123
333000
3000
05:48
Leave that up to us.
124
336000
2000
05:50
(Laughter)
125
338000
1000
05:51
Video: Actor: Clean coal -- you've heard a lot about it.
126
339000
2000
05:53
So let's take a tour of this state-of-the-art clean coal facility.
127
341000
6000
05:59
Amazing! The machinery is kind of loud.
128
347000
3000
06:02
But that's the sound of clean coal technology.
129
350000
4000
06:06
And while burning coal is one of the leading causes of global warming,
130
354000
3000
06:09
the remarkable clean coal technology you see here
131
357000
3000
06:12
changes everything.
132
360000
2000
06:14
Take a good long look: this is today's clean coal technology.
133
362000
3000
06:19
Al Gore: Finally, the positive alternative
134
367000
2000
06:21
meshes with our economic challenge
135
369000
2000
06:23
and our national security challenge.
136
371000
2000
06:25
Video: Narrator: America is in crisis -- the economy,
137
373000
2000
06:27
national security, the climate crisis.
138
375000
3000
06:30
The thread that links them all:
139
378000
2000
06:32
our addiction to carbon based fuels,
140
380000
2000
06:34
like dirty coal and foreign oil.
141
382000
2000
06:36
But now there is a bold new solution to get us out of this mess.
142
384000
3000
06:39
Repower America with 100 percent clean electricity
143
387000
3000
06:42
within 10 years.
144
390000
2000
06:44
A plan to put America back to work,
145
392000
2000
06:46
make us more secure, and help stop global warming.
146
394000
3000
06:49
Finally, a solution that's big enough to solve our problems.
147
397000
3000
06:52
Repower America. Find out more.
148
400000

150
411000
2000
07:05
One of the fastest ways to cut our dependence
151

on old dirty fuels that are killing our planet.

Narrator: Repower America. It's time to get real.
155
430000

07:26
Al Gore: There is an old African proverb that says,
156
434000
3000
07:29
"If you want to go quickly, go alone.
157
437000
2000
07:31
If you want to go far, go together."
158
439000

ABOUT THE SPEAKER
Al Gore - Climate advocateNobel Laureate Al Gore focused the world’s attention on the global climate crisis. Now he’s showing us how we’re moving towards real solutions.
Why you should listen
Former Vice President Al Gore is co-founder and chairman of Generation Investment Management. While he’s is a senior partner at Kleiner Perkins Caufield & Byers, and a member of Apple, Inc.’s board of directors, Gore spends the majority of his time as chair of The Climate Reality Project, a nonprofit devoted to solving the climate crisis.
He is the author of the bestsellers Earth in the Balance, An Inconvenient Truth, The Assault on Reason, Our Choice: A Plan to Solve the Climate Crisis, and most recently, The Future: Six Drivers of Global Change. He is the subject of the Oscar-winning documentary An Inconvenient Truth and is the co-recipient, with the Intergovernmental Panel on Climate Change, of the Nobel Peace Prize for 2007 for “informing the world of the dangers posed by climate change.”
Gore was elected to the U.S. House of Representatives in 1976, 1978, 1980 and 1982 and the U.S. Senate in 1984 and 1990. He was inaugurated as the 45th Vice President of the United States on January 20, 1993, and served eight years.
