Temperatures over Greenland Fast Approaching 400,000 Year High, Risk 15-19 Feet of Additional Sea Level Rise

It’s getting hot over Greenland. Not the kind of hot we think of as each summer rolls along. But the kind of hot that melts massive two-mile-high slabs of ice. How hot? Within a decade or two, Greenland temps could reach their highest levels in at least 400,000 years. And that’s a problem. A big fracking problem.

Why?

Because a mere 1 degree Celsius of warming separates Greenland from temperatures last seen during the warmest interglacial of the last million years. During that time, sea levels were 6-13 meters higher than today — a staggering 19-44 feet. Melt came from both West Antarctica and Greenland, but until this week we didn’t know what melt portion came from which glacier system. For a study published Wednesday in Nature has pinned down the extent of the Greenland ice sheet of 400,000 years ago. And this new knowledge gave researchers the ability…
