Arctic climate change marked by warmer, wetter conditions

At least since satellite observations began four decades ago, climbing temperatures have chipped away at Arctic sea ice causing earlier spring melting and later autumn freezing. Because ice reflects more sunlight than water does, shrinking sea-ice cover means that Arctic waters soak up more solar energy, which affects climate both regionally and globally. Now, a new study has documented how Arctic warming leads to wetter air and increased cloud cover, particularly during autumn and winter, which spurs even more warming in a self-reinforcing cycle.
