All polar bears across the Arctic face shorter sea ice season

Posted by External 10 days ago General
https://www.sciencedaily.com — A new study finds a trend toward earlier sea ice melt in the spring and later ice growth in the fall across all 19 polar bear populations, which can negatively impact the feeding and breeding capabilities of the bears. The paper is the first to quantify the sea ice changes in each polar bear subpopulation across the entire Arctic region using metrics that are specifically relevant to polar bear b Read More
