WFIR-LOGO-1Supporters of President Obama’s environmental policies rallied today in Roanoke, calling for action to support reduced carbon dioxide emissions. Rally speakers say the president’s plan will lower the frequency of extreme weather by reducing global warming.  The plan calls for reduced carbon dioxide emissions at coal-fired power plants; critics say that will mean lost jobs and higher electric bills, but supporters say it’s a health issue for all of us. WFIR’s Evan Jones has the story.
