'We've never seen anything like this': Arctic sea ice hit a stunning new low in May

It's the fourth monthly record, five months into this year.

The 2016 race downward in Arctic sea ice continued in May with a dramatic new record.

Another way to put it is this: The Arctic Ocean this May had more than three Californias less sea ice cover than it did during an average May between 1981 and 2010. And it broke the prior record low for May by a region larger than California, although not quite as large as Texas.
