Polar bears are swimming more as sea ice retreats study indicates

A study undertaken by scientists to understand swimming behavior in polar bears is showing an increase in this behavior related to changes in the amount and location of summer sea ice. The pattern of long-distance swimming by polar bears in the Beaufort Sea shows the fingerprint of climate change. Swims are occurring more often, in association with sea ice melting faster and moving farther from shore in the summer.
