Is the Polar Bear Threatened?

The Interior Department has barely two weeks to issue a ruling on whether the polar bear qualifies for protection under the Endangered Species Act, a federal judge decided this week. As the New York Times reports, Judge Claudia Wilken of Oakland, Calif., "rejected the government's contention that the case was too complicated to decide before June 30." Environmentalists argue that the melting of the Arctic icecap, which is reducing the polar bear's habitat, represents a serious threat to the species. The Times continues:

At a news conference earlier this month, the White House spokeswoman, Dana Perino, said environmentalists were inappropriately trying to use existing environmental laws, like the Endangered Species Act and the Clean Air Act, to address climate change. The result, Ms. Perino said, would be a "regulatory train wreck."

In related news, a dozen advocacy groups sued the federal government this week to compel it to protect gray wolves in the Rockies under the Endangered Species Act. The feds had previously protected that population of the animal, but it withdrew its endangered status in March, according to the Associated Press.

As I blogged in late March, the current administration has been more reluctant than its recent predecessors to grant protection to species not already listed as threatened or endangered, and environmental groups have sued it in efforts to broaden the act's reach. A U.S. News photo gallery shows several of the species that one group seeks to protect. In several cases, climate change is one of the threats these species face.

Few scientists now doubt that climate change is occurring, according to a new survey. The best partial solution could be to use less energy, as U.S. News just pointed out in its cover story. Technological advances could help, too, as could widespread individual actions. My colleague Bret Schulte previously laid down 10 ways we can each combat global warming. They're not written in stone tablets, but perhaps they should be.

polar bears

i think that it would be so sad to have another species gointothe endangered catagory.if there something that we can do to prevent the polar bear to not become endangered??my answer is yes,because all we have to do is : carpool more often,have factories such as mills,ie. lumber mills strain more of the chemicals out so it doesn't effect the polar bears enviroment.

Historic high populations

It is tough to call them endangered. The biggest problem with this issue is that villages need the right to shoot nuisance bears. Relocation does not work. THey are great navigators, and one was recently shot in Fort Yukon, 250 miles South of where they are normally found. They go where they find food, and will return time and time again. With such an explosion in their populations, they certainly are not endangered. It is the people who are at risk. Alaskans really don't need outsiders to tell them how to manage their wildlife.

ESA as a policy proxy

All the fuss over the Polar bear listing underscores the absence of other regulatory measures to deal with the emerging problem of climate change. See my April 29 and March 2 entries on www.esablawg.com, the law blog discussing the Endangered Species Act.

Thinking Harder

This blog is the public workshop of U.S. News writer and editor Ben Harder. In articles published in the magazine, he has covered a range of sciences, including medicine, human behavior, prehistory, and evolution. Here, he can explore those and other scientific fields more fully and more informally than is possible in print. He'll share whatever seems noteworthy or potentially useful, and he invites readers to do the same.

WTOP Audio

On Feb. 24, 2008, Ben discussed the link between artificial light and cancer on WTOP radio. Listen to the interview at WTOP News. He again talked about light pollution on WTOP on March 22, exploring its environmental effects.
