A federal appeals court has dismissed arguments against federal environmental regulations on greenhouse gas emissions. The Obama administration's clean car standards and industrial facility pollution permits survived the historic court battle. The three-judge appeals court panel unanimously ruled that climate change caused by carbon emissions does present a danger. The ruling builds on a 2007 Supreme Court decision to allow the federal government to use the Clean Air Act to control greenhouse gas emissions. Big business coalitions have already promised further legal action to stop the regulations that they claim will hamper the economic recovery. Pacifica's Dan Fritz reports.
