   Even using his own data set, Hansen was off by a factor of 4:

     You should really look at mid troposphere as that is where the greatest warming trend should have been observed and it’s also uncorrupted by urban height island effects. So was he out by nearly one order of magnitude? (Although the article probably refers to F and not C.)

       @Will: If you re-plot the same timeline (1986 to 2006 – Hansen’s 20-year time frame) using UAH, you get 0.4 degrees of warming, which is 0.1 degrees less than GISS. This puts Hansen off by a factor of 5.

       That agrees with my original “eye ball” calculation, assuming we’re talking in centigrade. 😉

   The first snow of winter has fallen across London and the Home Counties, causing delays to flights and rail services.

   Steve, the article also provided this-

   “Hansen said the average US temperature has risen from 1 to 2 degrees since 1958 and is predicted to increase an additional 3 or 4 degrees sometime between 2010 and 2020.”

   How can this be reconciled with his 1999 pronouncements of no warming in the US?
   Hansen predicts up to 6 degrees of warming between 1958 and 2010, or about 1 F per decade.

   I suspect Hansen may be an idiot savant, but evidence for the latter stubbornly refuses to reveal itself.

     Because the US is not the globe.
