2011 Still Cool

The HadCrut3 global temperature is now available for April so we have the first third of the year available. So far we have this year;January (temp anomaly 0.215). Cooler than 2010, 2009, 2007, 2006, 2005, 2004, 2003, 2002, 2001, 1999, 1998, 1995, 1992, 1991, 1988. Note: 2000 = 0.210 so it was essentially equal to 2011.February (temp anomaly 0.275). Cooler than 2010, 2009, 2007, 2006, 2004, 2003, 2002, 2001, 2000, 1999, 1998, 1995. Note: 1991 = 0.272. 1987 = 0.266.  1973 = 0.263.March (temp anomaly 0.328). Cooler than 2010, 2009, 2008, 2007, 2006, 2005, 2004, 2003, 2002, 2001, 2000, 1998, 1990.April (temp anomaly 0.396). Cooler than 2010, 2009, 2007, 2005, 2003, 2002, 2001, 2000, 1998.This shows that 2011 has had an exceptionally cold start to the year – possibly the coldest for over a decade. January is the 15^th coldest, February the 13^th, March, the 14^th and April the 9^th.Compare these months to the same months in 2010.January (temp anomaly 0.599) was the 5^th warmest.February (temp anomaly 0.462) was the 6^th warmest.March (temp anomaly 0.569) was the 2^nd warmest.April (temp anomaly 0.599) was the warmest.Last year the El Nino boosted temperatures. This year La Nina has cooled them. This did not stop some claiming that 2010 would be a record year because of global warming. I predict that if 2011 turns out to be exceptionally cold it will be because of the La Nina. It seems that to some if it’s hotter than average it’s man-made global warming, but if it’s cooler it’s a natural fluctuation.Feedback: david.whitehouse@netzerowatch.com
