A glacier in the north of Greenland is melting faster and in a different way than scientists previously thought, and this has troubling implications for the future speed of global sea-level rise. The new discovery was published in the Proceedings of the National Academy of Sciences Monday.
Peterman Glacier Photo: Andreas Muenchow, University of Delaware Associated Press: Daily tides stoked with increasingly warmer water ate a hole taller than the Washington Monument at the bottom of one of Greenland’s major glaciers in the last couple years, accelerating the retreat of a crucial part of the glacier, a new study found. And scientists worry that…

Scientists studying one of Greenland’s largest glaciers say it is a worrying sign that glaciers perched in the ocean could contribute more rapidly to sea level rise than currently forecast.
A closer look at the junction where a Greenland glacier crunches into the ocean floor, known as its grounding line, has revealed less stability amid the shifting of tides – and therefore a greater rate of melting – than previously estimated thanks...
