The way that the Petermann Glacier in Northwest Greenland is melting indicates that current models are too conservative. 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 […]
“This is unprecedented,” said one climate scientist. This past weekend, researchers at the National Science Foundation’s Summit Station observed rainfall at the peak of Greenland’s rapidly melting ice sheet for the first time on record—an event driven by warming temperatures.

“There will be substantially enhanced melting in the future—which is quite worrying,” said researchers. Researchers in Germany and Norway said Tuesday that a major portion of Greenland’s ice sheet is “at the brink” of reaching a frightening “tipping point”—the latest sign that global heating is causing irreversible damage to the world’s glaciers and that policymakers […]
Konrad Steffen, 68, died Aug. 8, 2020, when he fell into a meltwater-filled crevasse on the Greenland ice sheet. The glaciologist never worked in Alaska, but Steffen’s work influenced a scientist here, his countryman Martin Truffer. Truffer was born in Switzerland, as was Steffen. Truffer, a professor who studies glaciers at the Geophysical Institute […]
