On December 2, 2009, The Center for Biological Diversity and 350.org took an historic step in the desperate fight against climate catastrophe:  They petitioned the Environmental Protection Agency to establish a national pollution cap for greenhouse gases under the Clean Air Act.  They put out a call for organizations to join them, and we, the Amherst 350 Coalition, did.  You can read the letter to the EPA, and the list of organizations signing on – including ours – here.  There were 117 organizations as of Dec 28.
