Projections vs. Predictions: global warming models

Is there a difference between a “projection” and a “prediction?”  Well in the field of science, specifically with reference to global warming, there’s a world of difference according to Dr. Patrick Michaels of the Cato Institute.  In a column in the Washington Times, Michaels revealed that recent climate models are so fraught with errors and exaggerated assumptions, particularly with respect to temperature and precipitation, that they couldn’t even simulate 25-year temperature averages as the greenhouse effect changed over the last 100 years.  Since such so-called “projections” are more like “predictions,” it’s little wonder Michaels maintains that such global warming models are no different than tossing two dice on a craps table in Atlantic City!
