The Environmental Protection Agency released a long-secret document last week that reveals the agency's conclusions on global warming while President Bush was in office. The December 2007 document says greenhouse gases are dangerous and need to be regulated under the Clean Air Act.
"The Bush administration never accepted the need to regulate greenhouse gases," EPA Administrator Lisa Jackson tells Liane Hansen. "That's why the endangerment finding was never released."
The agency's decision to release that "endangerment finding" now highlights the stark differences between the EPA under Bush and the EPA under President Obama.
