It’s no news that Greenland is in serious trouble — but now, new research has helped quantify just how bad its problems are. A satellite study, published last week in the journal Geophysical Research Letters, suggests that the Greenland ice sheet lost a whopping 1 trillion tons of ice between the years 2011 and 2014 alone. And a big portion of it came from just five glaciers, about which scientists now have more cause to worry than ever.
It’s the latest story in a long series of increasingly worrisome studies on ice loss in Greenland. Research already suggests that the ice sheet has lost at least 9 trillion tons of ice in the past century and that the rate of loss has increased over time. Climate scientists are keeping a close eye on the region because of its potentially huge contributions to future sea-level rise (around 20 feet if the whole thing were to melt) — not to mention the damage it’s already done. Ice loss from Greenland may have contributed as much as a full inch of sea-level rise in the last 100 years and up to 10 percent of all the sea-level rise that’s been documented since the 1990s.
