He says that two of the three climatologists who have won Nobel prizes do not agree with those who believe human activities are causing global warming. Mr. Rogers says while the trapping of greenhouse gases is a plausible theory, it is too early to conclude that it is the correct one. Oceans, he notes, hold most of the thermal mass of the Earth, and they have not been properly studied. Most scientists agree that ocean currents and winds play a big role in world temperatures, but these factors are not included in computer models that forecast global warming. In fact, the models are so primitive that the Great Lakes and the Sierras are ignored.
Predictions are so absurd that one forecasts the flooding of Death Valley.
And most global-warming models fail to include cloud cover, the most important factor determining the Earth's temperature. That's a scientific, not a political, response. The president's decision to adopt incrementalism is an acknowledgment that he and Mr. Gore can't have it all right now. But that's their goal, and principled scientists and businesspeople should oppose their ultimate objective until the facts are in.
