And the environmental grassroots movement Step It Up held its second National Day of Climate Action this weekend. More than 1,400 events were held in all 50 states to call for a reduction of U.S. carbon emissions by 80 percent by the year 2050, the creation of millions of new “green” jobs, and a moratorium on coal-fueled power plants. Speakers addressing rallies around the country included the peace mom Cindy Sheehan in San Francisco and Democratic presidential hopeful John Edwards in New Orleans.
