New paper finds climate sensitivity to CO2 is only 0.43C, about 7 times less than the IPCC claims

The Hockey Schtick
A new paper published in the Open Journal of Atmospheric and Climate Change by renowned professor of physics and expert on spectroscopy Dr. Hermann Harde finds that climate sensitivity to a doubling of CO2 levels is only about 0.43C, about 7 times less than the IPCC claims, but in line with many other published low estimates of climate sensitivity. 

The paper further establishes that climate sensitivity to tiny changes in solar activity is comparable to that of CO2 and by no means insignificant as the IPCC prefers to claim. "
