Climate scientists using statistical modeling have estimated an 80 percent chance that climate change was responsible for the July 2010 Russian heatwave.
The paper by Stefan Rahmstorf and Dim Coumou from Germany’s Potsdam Institute for Climate Impact Research - Increase of extreme events in a warming world - was published in Proceedings of the National Academy of Sciences on October 25, 2011 notes:
"For July temperature in Moscow, we estimate that the local warming trend has increased the number of records expected in the past decade fivefold, which implies an approximate 80% probability that the 2010 July heat record would not have occurred without climate warming."
