The Environmental Protection Agency has announced that “[t]otal emissions of the six main greenhouse gases in 2006 were equivalent to” slightly over 7 billion metric tons(!) of carbon dioxide. (A metric ton is about 2,200 pounds, or 10% heavier than a standard ton.) The good news? Thanks to a warm winter and a cool summer, emissions were down 1.1% from 2005.
