EPA chief Lisa Jackson is not pleased that Congressional Republicans aim to halt the EPA's regulation of greenhouse gases, The Hill reports.

Bills have been floated in both Houses of Congress that would curtail the EPA's foray into limiting emissions of carbon dioxide and other so-called greenhouse gases. 

EPA Administrator Jackson counters that the President would "veto any legislation ... that would take away the EPA's greenhouse gas authority."

On the House side, Energy and Commerce Chairman Fred Upton (R-Mich.), he of the curlicue light bulbs, is introducing narrowly targeted legislation that would prevent use of the Clean Air Act to create a "cap-and-trade energy tax."  Fox News notes

The bill would nullify all of the steps the EPA has taken to date on the issue, including a threshold finding that greenhouse gases constitute a danger to the public health and welfare.

Democrats such as Sen. Barbara Boxer of California say the EPA is seeking to reduce pollution that damages the health of families and children.

This so-called "endangerment finding" sets the clock ticking on a vast array of taxes and regulation that EPA will have the power to impose across the economy, and all with little or no political debate.

This is a momentous decision that has the potential to affect the daily life of every American, yet most of the media barely noticed, and those that did largely applauded. When America's Founders revolted against "taxation without representation," this is precisely the kind of kingly diktat they had in mind.
