Congress should pass major climate change legislation to stave off cumbersome regulations from the EPA, Rep. John Dingell (D-Mich.) said today.

Noting that the the EPA's "endangerment finding" requires the agency to regulate greenhouse gases if Congress doesn't act, Dingell warned his colleagues to be wary of the executive bureaucracy.

"If you want something to shudder at, I beg you to take a look at that," Dingell said. "We will see better than 300 kinds of regulations coming from federal and state bodies."

Lawmakers should be "scared to death" by such the prospect of such regulation, Dingell added.

Dingell's support for the legislation has been critical. The long-serving Michigan Democrat was chairman of the House Energy and Commerce Committee before Rep. Henry Waxman (D-Calif.), the legislation's lead author, staged a coup of sorts after the 2006 midterm election. So Dingell's support comes in spite of both personal grudges and his energy-intensive district's concerns.
