WASHINGTON (AP) — The new Congress just got to work, but House Republicans are already moving to try to block the Obama administration from taking action on global warming.

GOP lawmakers have introduced several bills that would hamstring the Environmental Protection Agency from moving forward with regulations to reduce heat-trapping pollution from factories and other sources. The bills are part of a plan by House Republicans to reverse what they consider job-killing policies of the administration.

The bills introduced by Rep. Ted Poe of Texas, Rep. Marsha Blackburn of Tennessee and Rep. Shelley Moore Capito of West Virginia would stymie the EPA in different ways.

Democratic Sen. Barbara Boxer of California, who is chairwoman of the Environment and Public Works Committee, is vowing to vigorously oppose the Republican efforts.
