Climate Impacts of Waxman-Markey (the IPCC-based arithmetic of no gain)

By Chip Knappenberger -- May 6, 2009

Editor Note: Using mainstream models and assumptions, Mr. Knappenberger finds that in the year 2050 with a 83% emissions reduction (the aspirational goal of Waxman-Markey, the beginning steps of which are under vigorous debate), the temperature reduction is nine hundredths of one degree Fahrenheit, or two years of avoided warming by 2050. A more realistic climate bill would be a fraction of this amount. The author will respond to technical questions on methodology and results and invites input on alternative scenarios and analyses.

“A full implementation and adherence to the long-run emissions restrictions provisions described by the Waxman-Markey Climate Bill would result only in setting back the projected rise in global temperatures by a few years—a scientifically meaningless prospect.” (from below)

The economics and the regulatory burdens of climate change bills are forever being analyzed, but the bills’ primary function—mitigating future climate change—is generally ignored.…
