00:03I've charted a helicopter to take us over the ice so we can see what this looks like at scale.
00:36The ice sheet is the accumulation of snow that's built up over thousands of years.
00:43Cores have been dug down and drilled right through the ice and retrieved samples at least
00:49a hundred thousand years old.
00:52As the ice falls, the snow falls and the ice compacts, it slowly moves out to the coast
00:58to the exterior, and that's what forms the glaciers that flow down to the ocean.
01:05Just the epic scale of this sheet is incredible, it goes on for hundreds of kilometres, way
01:12up into the distance beyond the horizon, just nothing but a sea of white.
