On the recordJune 16, 2000
on June 12, the administration's National Assessment Coordinating Office, established under the authority of the Office of the President, released the first National Assessment on Climate Change. This report entitled ``Climate Change Impacts on the United States,'' is a political document. It is not a mainstream science document. It has not been peer-reviewed. The National Assessment attempts to predict in detail climate changes region-by-region within the United States over 100 years. Yes, region by region for 100 years. The charade of this effort is criticized by the Environmental Protection Agency's web page. This morning I checked the EPA's web page for its comments on computer climate model. It states: Virtually all published estimates of how climate could change in the United States are the result of computer models. . . . These complicated models . . . are still not accurate enough to provide reliable forecasts on how the climate may change; and the several models often yield contradictory results . . . Scientists are unable to say whether particular regions will receive more or less rainfall; and for many regions they are unable to even state whether a wetter or drier climate is more likely. This is from this morning's web page. The National Assessment does not highlight the large amount of uncertainty in long-term climate forecasting.
