Summer Arctic sea ice shrank to its fourth lowest level on record this month, dispelling faint hopes of a recovery, federal scientists said.
The National Snow and Ice Data Center announced Tuesday that the Arctic hit its summer minimum last week with 1.7 million square miles of sea ice, down 240,000 square miles from 2014. That’s a difference the size of California, New York and Maryland combined.
That means there’s no recovery in Arctic sea ice, despite claims of some climate change doubters, said Stroeve and Pennsylvania State University climate scientist Michael Mann, who wasn’t part of the government measurement team.
“We remain on a trajectory that is actually ahead of model predictions,” Mann said. “Arctic sea ice is one of several aspects of climate change that his happening even faster than originally predicted.”
