Emission Control Sought on Behalf of the Polar Bear

Laramie, WY – The conservation groups that successfully got polar bears listed as threatened last week were back in court today to try to get the government to limit greenhouse gas emissions.

Scientists say those gases have led to rapid melting of sea ice, which is where polar bears live.

But the government says it will not use the polar bear listing to regulate greenhouse gases. The groups, which include Greenpeace, are suing to force regulation.

Wyoming wildlife consultant Mike Lockhart has helped with a polar bear research project in Northern Alaska for the last eight years. He says he's seen the ice disappearing first-hand.

"Ice break-up just seems to be happening so much earlier now," he said.

Lockhart says he supports the environmental groups' lawsuit because the U.S. needs to get a handle on global warming.
