A new study from Dartmouth College shows how warming in the Arctic is rapidly changing an important landscape.

The research, by Ph.D candidate Rebecca Finger Higgens, says lakes in the Arctic tundra are shrinking as global temperatures rise.

Finger Higgens spent a summer in Greenland studying these lakes, which are scattered across a vast glacial landscape of rolling hills and low shrubs.

"It's a place where one degree of temperature change can make a really big difference."

Arctic temperatures have risen around 2.5 degrees celcius since 1985.
