Polar Bear Cubs Drowning due to Climate Change:

The study confirms the dangers of ice loss to Alaska’s polar bear population . It’s been widely theorized that adult polar bears have been forced to cross ever-longer stretches of open ocean as the polar regions heat up. The new work, by U.S. Geological Survey Alaska Science Center researchers, confirms that theory. It also reveals that these open-water swims have a dramatic effect on young cubs, which are forced to follow their mothers in search of food and solid ground. “This research is the first analysis to identify a significant multi-year trend of increased long-distance swimming by polar bears,” co-author Geoff York said Monday. “Climate change is pulling the sea ice out from under polar bears’ feet , forcing some to swim longer distances to find food and habitat.”
