Several weeks ago, Alaska Senator Lisa Murkowski blocked attempts to raise the ludicrously low cap on oil-company liability for catastrophes such as the Gulf of Mexico explosion and spill. Later, Senator Murkowski attempted to stop the EPA from implementing one of our most successful environmental laws -- the Clean Air Act -- to curb global warming. 

The EPA's recent common-sense finding that greenhouse gas pollution endangers public health -- a finding years in the making and finally ordered as a result of a Supreme Court decision -- is the first step in actually implementing the Clean Air Act to curb greenhouse pollution

Senator Murkowski's "Dirty Air Act," has been heard in the Senate; it would reverse this gain and stop the EPA from using the Clean Air Act to curb global warming.

Please sign the petition below urging your senators you oppose the "Dirty Air Act" and instruct then that they should oppose all efforts to scratch the Clean Air Act, whether standalone or included in climate legislation.
