NASA’s James Hansen originally warned that 350 PPM CO2 was the tipping point, and that we would all burn up and drown unless CO2 was reduced to those levels.
Data shows the exact opposite. All of Cleveland’s hottest days occurred below 350 PPM, with the hottest day occurring the week of Hansen’s 1988 Congressional testimony. Since that summer in 1988, Cleveland hasn’t had any really hot days.
The Arctic warmed ten degrees from 1900 to 1947, with CO2 below 310 PPM. It is 100% certain that Arctic warming has nothing to CO2 levels.
If the Antarctic ice regions and the major Greenland icecap should reduce at the rate of the present melting, he said, the oceanic surfaces would rise to catastrophic proportions.

Arctic warming prior to the 1940’s troubled Hansen, so he simply erased it.
Global warming appeals to the left because :
- It blames humans
- The solution is more government control
- The solution is more taxes
- The solution is less personal freedom
- The solution is wealth redistribution
It has nothing to do with science.
