I used to measure CO2 levels in the lab and am sure no one but a few know how CO2 is supposed to make us warmer. I am confident it cannot. Furthermore, measurements of CO2 are suspect as are temperatures. The people measureing temperature were/are activists and placed the thermometers next to heat sources and got invalid measurements. CO2 would be even harder to measure correctly and I doubt they have. In addition, NASA takes two separate measurements of average global temperature and has always gotten no rise. Only the bogus temperatures taken on land, by activists, shows any increase and still has to be rigged further by crooked scientists who make it higher than it is. CO2 must suffer the same insults, not that it matters.
