Link: Polar Bears Drowning Due to Melting Ice Caps [Preview]
Description:
The Times (UK) reports that scientists have found evidence that polar bears are drowning in the large open seas left behind by melting ice floes. From the article: "The researchers were startled to find bears having to swim up to 60 miles across open sea to find food. They are being forced into the long voyages because the ice floes from which they feed are melting, becoming smaller and drifting farther apart. Although polar bears are strong swimmers, they are adapted for swimming close to the shore. Their sea journeys leave them vulnerable to exhaustion, hypothermia or being swamped by waves. According to the new research, four bear carcases were found floating in one month in a single patch of sea off the north coast of Alaska, where average summer temperatures have increased by 2-3C degrees since 1950s."
