00:02Greenland sits on the top of the world between the Atlantic and Arctic oceans.
00:07And it's absolutely dominated by a vast ice sheet.
00:15I'm a geographer and field biologist, and I'm going to explore the critical role this ice sheet plays for all
00:23life here.
00:25Only the very margins of this land escape the ice that covers an astonishing four-fifths of the island.
00:35The narrow terrain around the coast is mostly barren and rocky tundra, but you're never far from the edge of
00:42the ice.
00:45This ice has experienced record melting in the last few decades.
00:50And I want to find out how global warming is profoundly affecting the country's climate and way of life.
