North Pole totally ice-free this summer

Polar scientists say that “for the first time in human history, ice is on course to disappear entirely from the North Pole this year.” The scientists “believe the chances of a totally ice-free North Pole this summer are greater than 50:50 because the normally thick ice formed over many years at the Pole has been blown away and replaced by huge swathes of thinner ice formed over a single year.”
