Computer modeling is not evidence

Re "Let evidence rule" (Letters, Feb. 20): The Roseville letter writer is right: on climate change, facts should rule.

Since 1980, the American Meteorological Society has tracked 102 different climate model projections; projections from models built by climate scientists eager to demonstrate catastrophic warming, using data from NASA and the National Oceanic and Atmospheric Association.

Richard McNider and John Christy, professors of atmospheric science at the University of Alabama in Huntsville and fellows of the American Meteorological Society, say those models have been "consistently and spectacularly wrong."

Between 1980 and today, the disparity between real world and modeled climatology has grown, meaning, the models were bad science at the start, yielded bad results and have only gotten farther from reality with their predictions.

McNider and Christy say, "The modelers insist that they are unlucky because natural temperature variability is masking the real warming." What?

Call me in one hundred million years with valid data.
