text: Climate Models: On the Global Warming Policy Foundation blog, David Whitehouse discusses the failure of the IPCC to discard models that clearly have no predictive value. The average of the models used greatly overestimate the increase in temperatures from additional CO2. The continued use of these models illustrates a failure in IPCC methodology procedures. Discarding models that greatly overestimate warming would result in a significant reduction in the upper bound of climate sensitivity estimates. Such action would render many climate issues, such as species extinction, moot. The huge amounts of money provided by climate alarm would shrink, endangering many climate researchers.
