McNider and Christy: Why Kerry Is Flat Wrong on Climate Change
...For instance, in 1994 we published an article in the journal Nature showing that the actual global temperature trend was "one-quarter of the magnitude of climate model results." As the nearby graph shows, the disparity between the predicted temperature increases and real-world evidence has only grown in the past 20 years.

When the failure of its predictions become clear, the modeling industry always comes back with new models that soften their previous warming forecasts, claiming, for instance, that an unexpected increase in the human use of aerosols had skewed the results. After these changes, the models tended to agree better with the actual numbers that came in—but the forecasts for future temperatures have continued to be too warm. ...
