Last year, global temperatures fell more sharply than any year on record. The drop of 0.65 to 0.75 degrees in 2007 offset all global warming that had occurred in the previous century. In fact, data from NASA shows the earth has been cooling since 2002 even though carbon emissions have risen at least 15 percent since then. Unfortunately, no one seems to have told Stephane Dion. The Liberal Leader recently changed his policy and proposed massive tax changes to reduce carbon emissions and supposed global warming.
