The summer sea ice cover over the Arctic raced towards oblivion in June, crashing through previous records to reach a new all-time low.
The Arctic sea ice extent was a staggering 100,000 square miles below the previous record for June, set in 2010. And it was 525,000 square miles below the 1981-2010 long-term average, according to the National Snow and Ice Data Center.
That means a vast expanse of ice — an area about twice the size of Texas — has vanished over the past 30 years, and the rate of that retreat has accelerated.
Aside from March, each month in 2016 has set a grim new low for sea ice cover, after a record warm winter.
