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 260,000 square kilometers (100,000 square miles) below the previous record for June, set in 2010. And it was 1.36 million square kilometers (525,000 square miles) below the 1981-2010 long-term average, according to the National Snow and Ice Data Center.
