The IPCC's catastrophic global warming claims for most skeptics border on the realm of insanity. In addition, the predictions for global temperatures by 2100 require a certain level of consensus irrationality, such as accepting runaway climate sensitivity due to never experienced positive feedback. Even the most basic predictions that are claimed by global warming proponents are totally out-of-sync with reality. The IPCC's CO2 growth predictions are such examples.
Unless atmospheric CO2 levels jump to a new growth rate immediately, the "Twilight Zone" IPCC climate science will continue to implode. (click on image to enlarge)
