E.P.A. Limit on Gases to Pose Risk to Obama and Congress

The New York Times reports:

With the federal government set to regulate climate-altering gases from factories and power plants for the first time, the Obama administration and the new Congress are headed for a clash that carries substantial risks for both sides.

While only the first phase of regulation takes effect on Sunday, the administration is on notice that if it moves too far and too fast in trying to curtail the ubiquitous gases that are heating the planet it risks a Congressional backlash that could set back the effort for years.
