More evidence CO2 hysteria is exaggerated

Quoting Dr. Richard Lindzen writing to Anthony Watts
regarding findings in his new peer reviewed paper:

“warming from a doubling of CO2 would only be about 1°C…

This modest warming is much less than current climate models suggest for a doubling of CO2. Models predict warming of from 1.5°C to 5°C and even more…

As a result, the climate sensitivity for a doubling of CO2 is estimated to be 0.7 K (with the confidence interval 0.5K – 1.3 K at 99% levels). This observational result shows that model sensitivities indicated by the IPCC AR4 are likely greater than the possibilities estimated from the observations.”
