What were the factors for Climate Variability in all Earths' history? Now find any text on Global Warming or Climate Change and use the "find" tool to look for keywords like "Solar Cycles", "Grand Solar Minimums/Maximums", geoMagnetic Reversals", "cosmic/galactic radiations", "cloud coverage", "cloud nucleation", "volcanism'', ''Milankowitch Cycles'', "etc".. you will find nothing.. now how can "97% of climatologists and scientists determine that Human Activity, namely CO2, is the main cause of Global Warming (lately replaced with Climate Change)",, while completely ignoring all other factors?? What kind of "science" is that? Furthermore, find any computer model for Climate Change and see if you find those parameters above.. nothing.. how can these models "predict" the climate without those parameters (that completely dwarf CO2 by the way)? How can policy be made based on such flawed "models"?? Oh and you know what? In all those computer models, the "Solar Radiation" parameter is a Constant,, not a Variable.. again, what kind of "science" is that? Political science?
