'Arctic amplification' to blame for Greenland's ice melt, scientists say

Arctic amplification explains the perpetuation of melting ice in the poles: As the Earth has heated up and melted ice, darker spots in the ocean that are uncovered by the loss have absorbed more solar radiation, further warming the sea and maintaining the cycle. The warmer waters could also balance more evenly with waters farther south, impacting the speed, intensity, and consistency of the jet stream, which in turn could bring hotter air farther north
