During October, RSS showed a large drop of 0.232 from September. It appeared that the battle for 2010 as hottest year ever was doomed. 2010 is turning out much cooler than 1998, with no hope of catching up.
But just when the battle appeared lost, the fighters at GISS got their second wind. Instead of a large drop in October temperature anomalies, they found a 0.08 rise! This keeps 2010 well ahead of their hottest year ever – 2005.
And of course, they are also keeping 2010 well ahead of 1998.
GISS is winning this battle by
making up extrapolating temperatures across vast regions where they have no data (pink below) and then reporting global temperatures to within one one-hundredth of a degree.
