More ambitious pollution cuts could save Arctic sea ice and the species that depend on it

The loss of Arctic sea ice is one of the clearest signs of human-caused climate change, and there's been nothing but blinking red alarms coming from the top of the world lately. The past four winters have seen such anemic sea ice growth that they've been the lowest four maximum sea ice extents since 1979. 
At the same time, the region’s climate has seen temperatures increase at more than twice the rate of the rest of the world, with record-shattering seasons becoming more common.
