2018 Arctic sea ice melt season just got a big headstart

Close, but no cigar. That assessment, though unscientific, well describes May 2018 sea ice extent in the Arctic Ocean – a month some polar experts thought could be one for the record books.

At the month’s mid-point, freakishly warm weather brewed above the northern ocean. But in the end, May 2018 staggered over the finish line in second place, and far from a photo finish at 12.2 million square kilometers (4.7 million square miles). That’s 310,000 square kilometers (120,000 square miles) greater than the all time May record set in 2016.

Yet the fact that so much debate swirled around May this year is news enough, as it’s often a month overlooked by the sea ice community and by the media, with May falling between March’s winter maximum sea ice extent and September’s summer minimum. But attention is shifting as global warming escalates.

“Now, what’s happening in winter and spring is starting to become very, very interesting,” says Mark Serreze, director of the National Snow and Ice Data Center which tracks and analyzes sea ice. September, he says, is no longer the only hot topic: “We’re seeing these big heatwaves over the North Pole in the middle of winter. Wow. That’s not supposed to happen and yet [it has] the last four winters.”
