In my Dec. 3 copy of the weekly e-newsletter of the Center for Biological Diversity is a commentary on the plight of polar bears in the melting Arctic. Sad. You can see for yourself below. /Gary
ENDANGERED EARTH ONLINE:
Conditions for polar bears in the melting Arctic are worse than imagined.
Since sea ice hit a record low in 2007, scientists studying satellite images had hoped it was recovering. But two weeks ago, a survey revealed that ice shown by satellites to be relatively old and thick is actually thin and fragile — multiyear layers of ice once up to 33 feet thick now can’t even support a single bear, leaving the iconic animal with fewer and fewer places of refuge in the summer.
Polar bears need thick ice for breeding, traveling, denning, hunting, and feeding — without it, they can drown and starve.
And the shrinking sea ice is already having a grisly impact. Witnesses have spotted at least seven cases of polar bears, desperate for sustenance, eating their own cubs this year around Churchill, Manitoba. The Hudson Bay winter sea ice isn’t appearing till weeks later than it used to, and the polar bears can’t hunt the seals they depend on to fatten up for winter.
