Across Greenland's vast white landscape, small teams of researchers from around the world are searching for clues about the potential effects of global warming on Greenland's ice. They're measuring the movement of glaciers, the density of the snow pack, the thickness of the ice and more, trying to gauge how much will melt and when. Greenland's Inuit people have been witness to the rapidly changing landscape. The Inuit have countless terms in their language to describe ice in all its varieties, and its disappearance directly affects their lives. Associated Press photographer Brennan Linsley recently spent some time on the massive Arctic island, documenting the researchers, the residents, and the varied ice that dominates the landscape.
