We found evidence of a catacIysmic
cIimate shift 1 0,000 years ago.
:06:08
The concentration of these naturaI
greenhouse gases in the ice cores. . .
:06:12
. . .indicates that runaway warming
pushed Earth into an ice age. . .
:06:15
. . .which Iasted two centuries.
:06:19
I'm confused.
:06:21
I thought you were taIking about
gIobaI warming, not an ice age.
:06:25
Yes, it is a paradox. . .
:06:26
. . .but gIobaI warming can trigger
a cooIing trend. Let me expIain.
:06:31
The Northern Hemisphere owes its
cIimate to the North AtIantic Current.
:06:36
Heat from the sun arrives at the equator
and is carried north by the ocean.
:06:40
But gIobaI warming is meIting the poIar
ice caps and disrupting this fIow.
:06:46
EventuaIIy it wiII shut down.
And when that occurs. . .
:06:49
. . .there goes our warm cIimate.
:06:51
Excuse me. When do you think this
couId happen, professor? When?
:06:57
I don't know. Maybe in 1 00 years,
maybe in 1 000. But what I do know is. . .
:07:01
. . .that if we do not act soon,
our chiIdren and grandchiIdren. . .
:07:04
. . .wiII have to pay the price.
:07:08
And who's going to pay the price
of the Kyoto Accord?
:07:11
It wouId cost the worId's economy
hundreds of biIIions of doIIars.
:07:15
With aII due respect,
Mr. Vice President. . .
:07:17
. . .the cost of doing nothing
couId be even higher.
:07:20
Our cIimate is fragiIe.
:07:22
At the rate we're burning fossiI fueIs
and poIIuting the environment. . .
:07:26
. . .the ice caps wiII soon disappear.
:07:28
Professor HaII. . .
:07:31
. . .our economy is every bit as fragiIe
as the environment.
:07:34
Perhaps you shouId keep that in mind
before making sensationaIist cIaims.
:07:39
WeII, the Iast chunk of ice
that broke off. . .
:07:42
. . .was about the size of Rhode IsIand.
:07:44
Some peopIe might caII that
pretty sensationaI.
:07:49
Stop global warming!
Stop global warming!
:07:53
I'm at the GIobaI Warming Conference
in New DeIhi. . .
:07:56
. . .where, if you can beIieve it,
it's snowing.
:07:58
The coIdest weather on record
has thrown the city into chaos. . .
