As the pomp and circumstance subsides as the first day of the Copenhagen confab  comes to a close, the Obama Administration is in full promotion mode on U.S. work on climate—despite decidedly  tepid  prospects for U.S. legislation to control greenhouse emissions.
The multifaceted message is being delivered in multimedia at live events , a fancy pavilion , and on a swanky Web site . (By contrast, journalists complained at U.N. climate meetings during the Bush Administration that it was difficult to get questions answered by the Administration.)
Here's their pitch: America has sped up regulations  for carbon emissions for cars. It's boosted energy research way up (including, as seen today, rather wild research .) The full House of Representatives has passed a bill and the Senate has passed one in committee, allowing Obama some credibility when he committed  the United States to a 17% cut in 2005 emissions by 2020, if Congress acts.
Today the Administration went the final step, announcing  that EPA has legally determined greenhouse gasses to be a danger to human health under the Clean Air Act.
"The Clean Air Act can complement a legislative solution," said EPA Administrator Lisa Jackson in a press conference. Regulations on large emitters have yet to be announced, but now they can be. But EPA lawyers will be even busier than they were preparing the determination just announced—the first  in a series of expected lawsuits was filed today by the Competitive Enterprise Institute. Next year energy-intensive industries will have to start measuring their greenhouse pollution under the new rules.
As a side note, today White House spokesman Robert Gibbs was asked about why the President moved his Copenhagen visit to the end of the meeting: "Based on development primarily with the Chinese and the Indians," he said, Obama felt, "some agreement was likely to need some help from world leaders."
