Here are some excerpts from the editorial:

"The Obama administration has always had a backup plan in case Congress failed to pass a broad climate change bill. The Environmental Protection Agency would use its Clean Air Act authority to regulate greenhouse gases. Regulation, or the threat of it, would goad Congress to act or provide a backstop if it did not.

...

Now some senators seem determined to undercut the E.P.A.’s regulatory authority. These include not only Republicans who panic at any regulation, but also Democrats who say they worry about climate change but insist that the executive branch stand aside until Congress gets around to dealing with it.

...

These senators seem to have bought the hype, spun by industry, that the E.P.A. will run amok. This is not the way we read the intentions of the E.P.A. administrator, Lisa Jackson, who has promised that whatever regulations she proposes will be gradual, cost-effective and affect only the largest facilities.

Nor is it the way we read Congress’s responsibility to the country. That is to address the very real danger of climate change, not deny the government the tools it needs — and legally has — to fight it.
