Glaciers worldwide are withering. Half of them will disappear by the end of this century, and much of the lost ice will vanish from mountains in Alaska, scientists say. Authors of a recent cover story in the journal Science used high-performance computers to predict the fate of 215,547 glaciers on Earth. They excluded the great […]
A proposal to cover Arctic sea ice with layers of tiny hollow glass spheres about the thickness of one human hair would actually accelerate sea-ice loss and warm the climate rather than creating thick ice and lowering the temperature as proponents claim. Sea ice, by reflecting the majority of the sun’s energy back to space, […]
New research shows two widely used computer models that predict summer melt pond formation on sea ice greatly overestimate their extent, a key finding as scientists work to make accurate projections about Arctic climate change. The finding comes from measurements made during a year-long expedition aboard the research vessel Polarstern. For the Multidisciplinary Drifting Observatory for […]
A group of University of Alaska Fairbanks faculty, students and staff has been conducting Arctic fieldwork in Utqiagvik since mid-April to measure snowmelt, but the melt only started in mid-June. This is an exceptionally late melt year. The Snow Albedo Evolution in the Arctic team, or SALVO, has been working hard through the midnight sun, […]
