OKLAHOMA CITY (AP) - One of U.S. Sen. Jim Inhofe's opponents in the debate about global warming criticized the Oklahoma Republican for comments he made last week about the issue.

Sen. Barbara Boxer, D-Calif., said Inhofe _ an avowed critic of the theory that human activity is responsible for global warming _ is choosing to ignore the advice of the world's leading scientists, The Oklahoman reported from its Washington bureau.

Boxer is now the chairman of the Senate's Environment and Public Works Committee, which Inhofe led until the GOP lost control of the Senate after the last election.

“There are always people who will say HIV doesn't cause AIDS,” Boxer said Monday during a speech on the Senate floor. “There are always those who will say cigarette smoking doesn't cause cancer. … You can come down to this floor and say everything is beautiful, but you're not in touch with reality.”

During his speech Friday, Inhofe said the media, environmental groups and “Hollywood” liberals, among others, have exaggerated the causes and effects of global warming.

Inhofe maintains that a growing number of scientists are agreeing with him and have questioned computer models used to predict future temperatures and water levels.

Boxer is a key proponent of legislation, sponsored by Sen. Joe Lieberman, I-Conn., and Sen. John Warner, R-Va., that would mandate limits on greenhouse gas emissions.

Boxer said Inhofe is “not being honest with the facts” and said the global warming issue “is about God's creation, which is in jeopardy.”

Inhofe, speaking after Boxer on Monday, challenged some of her assertions and said proposals to cap greenhouse gas emissions can hurt economic activity while having little effect in limiting emissions.

He also said weather-related disasters, including the recent California wildfires, have incorrectly been attributed to having been caused by global warming.
