The flow of Greenland’s glaciers toward the sea may have increased significantly in the past decade, but a new report in Nature finds that rate of increase is unlikely to continue. “The loss of ice has doubled in the past 10 years, but it’s not going to double again,” said lead author Faezeh Nick, a glaciologist at the University Centre in Svalbard, in Longyearbyen, Norway, in an interview.
That conclusion, based on a new, sophisticated computer model, makes the worst-case scenario of sea level rise — an increase of 6 feet or so, on average, by 2100 — look less likely to play out.
That’s the good news. The bad news is that, in the model at least, the slowdown doesn’t necessarily bring glaciers back to their original, stately rate of flow.
