Hot on the heels of the Lewis and Curry paper, we have this new paper, which looks to be well researched, empirically based, and a potential blockbuster for dimming the alarmism that has been so prevalent over climate sensitivity. With a climate sensitivity of just 0.43°C, it takes the air out of the alarmism balloon.
The Hockey Schtick writes: 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.
The following is a Google translation from the German EIKE site with an overview of the main findings of the paper, followed by a link to the full paper [in English].
Currently climate sensitivity (discussed for example here ) is claimed by the IPCC mid-value to be 3.0 C (AR4) as the most probable value, but others have determined much lower values of 1.73C or 1C or even 0.43C. Prof. Hermann Harde, renowned physicist and Spektral analytiker has determined from his new paper the climate sensitivity is 0.43 C
