James Hansen received $720,000 from OSI, Open Society Institute a Geroge Sorros group and to fund his media campaign. Then he received $250,000 from the Heinz group (Mrs. John Kerry) and supported John Kerry in 2004.
Then the hockey puck theory was kicked out from him here:
After the the GISS data error was revealed, Hansen finally agreed to make public the method he uses to generate "official" temperature records from the actual readings. That process has been revealed to be thousands of lines of source code, containing hundreds of arbitrary "bias" adjustments to individual sites, tossing out many readings entirely, and raising (or lowering) the actual values for others, sometimes by several degrees. Many areas with weak or no rising temperature trends are therefore given, after adjustment, a much sharper trend. A full audit of the Hansen code is currently underway, but it seems clear that Hansen has more explaining to do.
