A new study finds the island’s ice sheet is retreating 20% more than previously thought. New research on the rate at which Greenland’s glaciers are melting shed new light on how the climate emergency is rapidly raising the chance that crucial ocean current systems could soon collapse, as scientists revealed Wednesday that the vast island […]
University of Alaska Fairbanks scientists will make several trips to Greenland over two years to study how meltwater and the ocean affect glacial ice loss. The four-year research project, funded by a $565,000 National Science Foundation grant, will create a traveling museum exhibit about the drivers of Arctic climate change. The exhibit will appear first […]
Findings raise new questions about climate dynamics During the last ice age, massive icebergs periodically broke off from an ice sheet covering a large swath of North America and discharged rapidly melting ice into the North Atlantic Ocean around Greenland, triggering abrupt climate change impacts across the globe. These sudden episodes, called Heinrich events, occurred […]
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 […]
