New paper finds climate sensitivity to CO2 is 73% less than claimed by IPCC

The Hockey Schtick
"A new peer-reviewed paper published in Gondwana Research finds from paleoclimate proxies that climate sensitivity is only 0.8°C for a doubling of CO2 concentration from 280 to 560 ppm, 73% less than claimed by the IPCC. The paper adds to many other peer-reviewed papers finding the IPCC estimates of CO2 climate sensitivity are greatly exaggerated."
