In explaining his refusal, EPA administrator Stephen Johnson last week wrote that California had not proved "compelling and extraordinary conditions" allowing it to be granted a waiver under the federal Clean Air Act because the rest of the nation also suffers the effects of global warming. Mr. Johnson told the Associated Press:
"I'm not saying that California isn't experiencing problems as a result of global climate change.... There are in fact other parts of the country that are actually worse."
Environmentalists and California officials disagree with Johnson's interpretation, contending that California has been granted Clean Air Act waivers in the past to deal with problems that are happening elsewhere, such as diesel pollution. The AP story points out:
"Critics also contend that California does, in fact, have uniquely worse problems from global warming compared with other states, including wildfire risks, air pollution, and water supply shortages."
