Oct. 2010 UAH Global Temperature Update: +0.42 deg. C Roy Spencer, Ph. D.
As the tropical tropospheric temperatures continue to cool, the global average is finally beginning to follow suit:+0.42 deg. C for October, 2010. This is the lowest monthly temperature anomaly weÂ’ve seen in what has been a very warm year.
For those following the race for warmest year in the satellite tropospheric temperature record (which began in 1979), 2010 is still within striking distance of the record warm year of 1998. Here are the 1998 and 2010 averages for January 1st through October 31:
1998 +0.57
2010 +0.54
Note that the difference between the two is not statistically significantÂ…just symbolically.
