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 […]

Breakup happened on the Yukon River here at its first settlement in the United States at around 2 a.m. on Saturday, May 7, 2022.
