Correction for drifting satellite increases Armstrong lead
Adjustments to allow for a drifting satellite have found UAH temperatures to be flatter than previously estimated. As a consequence, Armstrong’s bet is safer than before. Gore’s forecast errors to date are 16% larger than the errors from Armstrong’s no-change forecast, and the no-change forecast of global mean temperatures has so far been more accurate than the Gore/IPCC forecast for 67% of the months covered by the bet.
