Then study Paleontology, and Paleoclimatology, then study weather records and discover that satellite temperatures are not accepted for establishing record high or low temperatures, weather records don't go back more that a few decades making them too limited a data set to compare to 4 billion years of earth's history, study the science of meterology and pay close attention the orographic weather section, and the fact that the atmosphere is never uniform or static and neither is the climate. NASA has some great satllite imagery showing higher concentrations of CO2 downwind of rain foressts and jungles than downwind of human populated areas. You guessed it, CO2 is not uniformly distributed through the atmosphere. Then check out OSHA regulations on workplace exposure to CO2, they don't get worried until CO2 is measured at 10,000 parts per million, not so deadly as the courts have ruled. Makes 400 parts per million look pretty insignificant. Yeah. a lot of science to learn and follow to the truth.
