Sellers: IceBridge is probably one of the most important

4
00:00:12.030 --> 00:00:16.020
field campaigns we have running right now.

5
00:00:16.040 --> 00:00:20.020
The world is warming, and it's warming faster in the north,

6
00:00:20.040 --> 00:00:24.030
around the Arctic, than anywhere else. By a factor of two-and-a-half. It's two-and-a-half times

7
00:00:24.050 --> 00:00:28.030
increase in warming here compared to the global average.

8
00:00:28.050 --> 00:00:32.070
So this is where it's all happening. And as a consequence,

9
00:00:32.090 --> 00:00:36.070
the ice is melting fast. It's melting on the Arctic Ocean,

10
00:00:36.090 --> 00:00:40.080
and the ice mass on top of Greenland is melting and falling into the Atlantic.

11
00:00:40.100 --> 00:00:44.090
So we're mapping that using aircraft and satellites where we can.

12
00:00:44.110 --> 00:00:48.090
And of course we've got people on the ground checking against these data as well.

13
00:00:48.110 --> 00:00:52.110
So this is ground zero for global warming. We're doing a lot of work here

14
00:00:52.130 --> 00:00:56.130
we've put a lot of effort into it, and I think it's paying off in terms of

15
00:00:56.150 --> 00:00:56.150
improved understanding.

00:00:56.170 --> 00:00:59.150
