Polar bear habitat at center of Alaska drilling debate

Native Alaskans and environmentalists have filed a suit to prevent the federal government's sale of drilling leases in Alaska's Chukchi Sea. The sales, set to begin Wednesday, will allow drilling in about 30 million acres, including critical polar bear habitat, environmentalists say. A decision on whether to list polar bears as "threatened" under the Endangered Species Act (ESA) is expected this week as well.
The potential designation has left the Pacific Legal Foundation, a conservative public-interest law firm, poised to challenge "any arbitrary, unjustified ESA listing" of the iconic Arctic bear, setting up a likely court battle. Property-rights advocates and business groups have been weighing in as well.
Researchers differing over the impact of climate change also affects the debate. Hundreds of prominent scientists are urging Congress to pass legislation that would curb global warming in order to protect wildlife, including polar bears. But other experts say the data used to bolster the argument for ESA listing – in particular computer modeling showing declines in polar bear populations because of climate change and other factors – are based on "questionable assumptions."
All of this is uncharted territory for government-ordered species protection, which typically is based on numbers dwindling toward extinction.
Polar bear populations in fact may be larger than they were decades ago. By some estimates there were as few as 5,000 polar bears in the 1950s when hunting for sport and profit was far less regulated. Today, scientists believe there are 20,000 to 25,000 polar bears, though this is still about 60 percent below historic levels. And many scientists say the loss of Arctic sea ice, which bears rely on for hunting and denning, is accelerating to record levels due to global warming. As a result, US Geological Survey scientists recently warned that projected changes in sea-ice conditions could lead to the loss of about two-thirds of the world's polar bear population by midcentury.
"Global warming is already causing serious damage and disruptions to wildlife and ecosystems, and reliable projections call for significant additional damage and disruptions," more than 600 scientists warned in a letter to members of Congress last week.
