Arctic amplification: Why Greenland’s ice is quickly melting

During summer 2015, Greenland experienced its highest rate of glacier melt. A new study, published on June 9 in “Nature Communications,” shows the record-high melt is linked to the anticipated effects of a phenomenon known as Arctic amplification.

Arctic amplification refers to the faster warming of the Arctic compared to the rest of the Northern Hemisphere as sea ice disappears. It is fueled by a feedback loop: rising global temperatures are melting Arctic sea ice, leaving dark open water that absorbs more solar radiation, and that warms the Arctic even more.
