Sellers: IceBridge is probably one of the most important
field campaigns we have running right now.
The world is warming, and it's warming faster in the north,
around the Arctic, than anywhere else. By a factor of two-and-a-half. It's two-and-a-half times
increase in warming here compared to the global average.
So this is where it's all happening. And as a consequence,
the ice is melting fast. It's melting on the Arctic Ocean,
and the ice mass on top of Greenland is melting and falling into the Atlantic.
So we're mapping that using aircraft and satellites where we can.
And of course we've got people on the ground checking against these data as well.
So this is ground zero for global warming. We're doing a lot of work here
we've put a lot of effort into it, and I think it's paying off in terms of
improved understanding.
