Atmospheric CO2 concentration is a LAGGING INDICATOR of climactic temperature.
Based on research by Svensmark and Calder, CO2 has nothing to do with climate. Read “The Chilling Stars” to get the real story. We’re going into a period of global cooling thanks to our very quiet star.
That's true, but doesn't change the fact that the current rise in CO2 is mostly manmade. The oceans did warm naturally maybe a degree or two over the last few centuries or so. That's enough to create a rise of 5-10 ppm in atmospheric CO2. The rest of the rise, including annual rises of 2-3 ppm are due to manmade CO2. Whether that manmade CO2 creates more warming is not reqlly in doubt, but the amount is probably small. The doomsters have to fudge the models with extra water vapor and weather pattern changes to get a lot of future warming.
