Global Warming Blamed for Walrus Deaths

According to this article, they are having a tough time due to disappearing ice.

Unlike seals, walruses cannot swim indefinitely. The giant, tusked mammals typically clamber onto the sea ice to rest, or haul themselves onto land for just a few weeks at a time.

But ice disappeared in the Chukchi Sea this year because of warm summer weather, ocean currents and persistent eastern winds, Garlach-Miller said.

As a result, walruses came ashore earlier and stayed longer, congregating in extremely high numbers, with herds as big as 40,000 at Point Shmidt, a spot that had not been used by walruses as a "haulout" for a century, scientists said.

Walruses are vulnerable to stampedes when they gather in such large numbers. The appearance of a polar bear, a hunter or a low-flying airplane can send them rushing to the water.

Sure enough, scientists received reports of hundreds and hundreds of walruses dead of internal injuries suffered in stampedes. Many of the youngest and weakest animals, mostly calves born in the spring, were crushed.

Disappearing ice? That couldn't be happening. Didn't some judge in England take issue with Al Gore's movie? Why only a contrarian pinhead would take the side of the entire scientific establishment. over a smart judge in England wouldn't they?

No wait, actually he didn't disagree with the basic premise of man made global warming according to this article in the Times of London.

Despite finding nine significant errors the judge said many of the claims made by the film were fully backed up by the weight of science. He identified “four main scientific hypotheses, each of which is very well supported by research published in respected, peer-reviewed journals and accords with the latest conclusions of the IPCC”.

In particular, he agreed with the main thrust of Mr Gore’s arguments: “That climate change is mainly attributable to man-made emissions of carbon dioxide, methane and nitrous oxide (‘greenhouse gases’).”

The other three main points accepted by the judge were that global temperatures are rising and are likely to continue to rise, that climate change will cause serious damage if left unchecked, and that it is entirely possible for governments and individuals to reduce its impacts.
