Here’s a helpful reminder that not all Republicans oppose climate action. Former EPA administrators who served under Republican presidents Richard Nixon, Ronald Reagan, and George Bush I and II spoke out on Wednesday in support of federal efforts to regulate CO2 emissions from power plants. They appeared at a Senate hearing organized by Democrats to discuss EPA’s recently proposed power-plant rules. From USA Today:

“We have a scientific consensus around this issue. We also need a political consensus,” said Christine Todd Whitman, the former New Jersey Governor and first EPA administrator under President George W. Bush, who resigned her post after disagreeing with the White House’s direction on pollution rules.

Whitman was joined by William Ruckelshaus, the nation’s first EPA administrator under President Richard Nixon, William Reilly, who led the EPA under President George H.W. Bush, and Lee Thomas, who was administrator under Reagan. …

[T]he four EPA administrators … said the Obama administration had worked hard to make the proposal flexible and workable, using authority provided by Congress.

More from McClatchy:

Whitman … said she was frustrated by the debate over whether the EPA had the authority to take the action it did on carbon pollution.
