The land weather station closest to the North Pole, at the tip of Greenland, spent more than 60 hours above freezing in February. Before this year, scientists had seen the temperature there rise above freezing in February only twice before, and then extremely briefly. Last month’s record-high temperatures have been more like those typical of May, said Ruth Mottram, a climate scientist at the Danish Meteorological Institute.

Of nearly three dozen different Arctic weather stations, 15 of them were at least 10F (5.6C) above normal for the winter.
