Climate scientist David H. Douglass, John Christy and Fred Singer analyzed 22 climate models and found their predictions at odds with actual warming over the past 30 years.
Singer writes "Dire predictions of future warming are based almost entirely on computer models, yet these models do not accurately understand the role of water vapor. Plus, computer models cannot account for the observed cooling of much of the past century (1940-1975), nor for the observed patterns of warming. For example, the Antarctic is cooling while models predict warming. Where models call for middle atmosphere to warm faster than the surface, the actual observations show the exact opposite."
Many top scientists point out that climate models are incapable of handling such factors as cloud cover and water vapor (the dominant greenhouse gas), thereby distorting climate predictions.
Additionally, these scientists note that the models do not reflect the actual causes of global warming. Richard Lindzen, a professor of meteorology at MIT, says the models used by the IPCC and other alarmists assign too much warming resulting from increases in atmospheric carbon dioxide (CO2), rendering the model's prediction inaccurate.
No current climate model can explain the causes of climate changes, accurately predict future climate or form a sound basis for environmental policy like man being a cause of global warming. Enviro/wackos refuse to face the facts, instead they put their faith in Reverend Gore's bible, "An Inconvenient Truth," and are herded like flocks of sheep into the world's greatest hoax, which leads the world into a great recession, maybe even a depression.
Not many of the enviro/wackos remember the great depression and the great Midwest dust bowl of the 1930s. That's just the cyclic nature of Mother Nature and it could happen any time in the future and without man's help. In those days there were more homes than cars (Model Ts) for those who don't know. I wonder if all that horse pucky with its CO2 could have caused the great dust bowl of the 30s? Ask Al Gore if you're one of his cult members.
