Washington DC — Scientists are seeing surprising melting in Earth’s polar regions at times they don’t expect, like winter, and in places they don’t expect, like eastern Antarctica.
New studies and reports issued this week at a major Earth sciences conference paint one of the bleakest pictures yet of dramatic warming in the Arctic and Antarctica.
Alaskan scientists described to The Associated Press Tuesday never-before-seen melting and odd winter problems, including permafrost that never refroze this past winter and wildlife die-offs.
“The Arctic is experiencing the most unprecedented transition in human history,” report lead author Emily Osborne, chief of Arctic research for NOAA, said Tuesday.
The National Oceanic and Atmospheric Administration Tuesday released its annual Arctic report card, detailing the second warmest year on record in the Arctic and problems, including record low winter sea ice in parts of the region, increased toxic algal blooms, which are normally a warm water phenomenon, and weather changes in the rest of the country attributable to what’s happening in the far North.
