While doing some historical studies in preparation for an article in Cato’s Regulationmagazine, we found that we once discovered the information equivalent of antimatter, namely, “anti-information”.
This breakthrough came when we were reviewing the first “National Assessment” of climate change impacts in the United States in the 21st century, published by the U.S. Global Change Research Program (USGCRP) in 2000. The Assessments are mandated by the Global Change Research Act of 1990. According to that law, they are, among other things, for “the Environmental Protection Agency for use in the formulation of a coordinated national policy on global climate change…”
One cannot project future climate without some type of model for what it will be. In this case, the USGCRP examined a suite of nine climate models and selected two for theAssessment. One was the Canadian Climate Model, which forecast the most extreme warming for the 21st century of all models, and the other was from the Hadley Center at the U.K Met Office, which predicted the greatest changes in precipitation.
