"Global warming hysteria is based to a large extent on the unproven predictions of climate models. These numerical models are based on many simplified approximations of very complicated physical processes and phenomena. My biggest concern is their [computer models'] lack of ability to adequately handle water vapor and clouds, which are much more important as climate factors than anthropogenic [human] contributors. Until we can realistically simulate types of clouds, their optical thicknesses, and their altitudes, which we have a difficult time doing for short-term weather forecasts, I can't have much faith in climate models."
