Additional Facts 12. The IPCC unvalidated computer model scenarios have already missed their earlier predictions, including the current global cooling.
None of the 20 plus model scenarios predicted by the IPCC accounted for the current eight year cooling that is occurring in spite of a continuous 24/7 rise in atmospheric CO2. (See the figures below).
Note the monthly global temperatures; up, down, steep rise, low rise, etc. all this despite a steady increase in CO2 that is in Earth's atmosphere 24/7, worldwide.
These charts demonstrates the lack of accuracy of the climate models and the illogic of trusting them for century-long forecasts. That the IPCC computer models cannot accurately predict Earth's past, known climate history, much less the future decades or centuries ahead, is no surprise in that the modelers did not allow for solar variations that are known to occur or for possible extraterrestrial influences that seem to correlate with climate changes better than the rise and fall of atmospheric CO2 levels. The IPCC modelers were instructed to ignore such possible effects. Yet these same models are being used to scare the public to death in order to get policies enacted just in case the science is wrong and CO2 might be having an as yet unknown effect on global warming. To take this "tilting at windmills" approach, especially because of all the known, solidly documented benefits of more, not less, atmospheric CO2, is senseless.
