Global Temperature in 2011, Trends, and Prospects |
Our analysis of 2011 global temperature is available on my web site. http://www.columbia.edu/~jeh1/mailings/2012/20120119_Temperature.pdf This may be my final e-mail. Last year, in a moment of temporary insanity, I agreed to participate in Chesapeake Climate Action Network's annual polar bear plunge this Saturday. One of my sisters claims that a padded wagon is on the way. If I catch pneumonia Anniek may shoot me. If you want to join the fun (it can't really be all that bad, and it's for a good organization), info can be found by clicking here. ~Jim Excerpt: Oklahoma-Texas-Northern Mexico in 2011 and the Moscow region in 2010 provide examples of summer heat anomalies that exceeded 3σ relative to the 1951-1980 climatology. In the 1951-1980 period of climatology the area with temperature anomaly exceeding +3σ was only a few tenths of one percent. However, the area covered by such extreme anomalies has increased with global warming. +3σ anomalies covered 7% of the area with observations in Jun-Jul-Aug 2009, 13% in 2010, and 9% in 2011 (Hansen et al., 2012). Increased occurrence of such extreme anomalies as a result of global warming, by more than a factor of 10, implies that we can attribute such recent extreme anomalies, including that in Texas and Oklahoma, to global warming. |
