The headline in the Globe was certainly ominous -- "Clark's Hydro policy threatens to collapse B.C.'s climate change progress, scientist says."

The purported policy change seemed scary -- the government might roll back the requirement for BC Hydro to be able to meet domestic electricity requirements in drought conditions. And the scientist's description of the consequences is also quite a fright -- BC Hydro will be forced to rely on coal-fired electricity if the policy change goes through.

This week, the House voted to shut down the carbon regulation program at the Environmental Protection Agency, but the Senate rejected four different measures that would have stopped or delayed EPA action. The EPA, as mandated by the Supreme Court, has been moving forward with regulations that would require carbon polluters to apply for EPA permits and to use the best available method to start limiting carbon emissions.

During the State of the Union address earlier this week, President Barack Obama spoke at length about clean energy, with nary a mention of climate change. This is the new environment in which America's energy policy is being made.

Just two years ago, Democrats were rallying to combat climate change, one of the most worrying challenges the country faces. But now, Obama has apparently given up his plan to openly fight climate change during his presidency. It's hard to imagine how, even in a second term, he would choose to re-fight the lost battle to create a cap-and-trade system.

A year ago, it seemed possible -- likely, even -- that President Barack Obama would sweep into the international negotiations on climate change at Copenhagen and make serious progress on the tangle of issues at stake. The reality was quite different. This year, the expectations for the United Nations Climate Conference in Cancun are less exuberant.

A chill is coming to Washington. A wave of climate change deniers were elected to office this week, and come January, we can expect a freeze in all reasonable and productive discussion about the fate of the planet.

Last year, the political discussion about climate change and carbon regulation was complicated and bogged down, but at least it was happening.

Who are the deniers?

Grist has pulled together a list of the climate deniers headed into power in the Senate. “Overall, the Senate next year will be more hostile to climate action than ever before,” the site’s staff says.

Congress comes back into session next week, but environmentalists and climate change activists have given up on the legislature. Instead, activists are planning to spur popular concern about these issues, until calls for change are so loud that Congress must listen.

Today, climate change reformer Bill McKibben will ask President Obama to reinstall a solar panel that first graced the White House roof during the Carter presidency. In the months to come, advocates hope to lead more radical direct actions that force more Americans to confront the issues at hand -- and hopefully pressure change from the bottom up.

Yesterday, Senate Majority Leader Harry Reid (D-NV) introduced a limited energy bill that responds to the oil spill and promotes energy efficiency. Reid's action is a signal that the Senate will not pass climate legislation before November, although Sen. John Kerry (D-MA) said that a climate bill could come up in the lame-duck session following the election.

"The Senate's climate bill is officially dead," Kate Sheppard writes at Mother Jones. "And given that Democrats will almost certainly hold fewer seats in Congress next year, major action on the climate is unlikely to be revived anytime soon."

This summer, Americans are cranking up their air conditioning. At the same time, Senators are letting climate legislation cool its heels in Washington. Ultimately, both of these summer trends are contributing to climate change. Air conditioning dumps greenhouse gases into the environment, and without climate legislation that caps the country’s carbon emissions, America’s share of global carbon levels will only continue to grow.
