According to a new NASA study, "January 2000 to December 2009 was the warmest decade on record. Looking back to 1880, when modern scientific instrumentation became available to monitor temperatures precisely, a clear warming trend is present, although there was a leveling off between the 1940s and 1970s." But, you know, it snowed in Copenhagen during the climate summit, so WHO KNOWS IF GLOBAL WARMING IS EVEN REAL?
