Calculations suggest that Global warming caused by the doubling of CO2 will be less than 0.6K

Guest essay by Saburo Nonogaki It has been said that the averaged earth surface temperature would be 255K if no green-house-effect(g-h-e) gases were contained in the atmosphere, and is 288K at present where the atmosphere contains g-h-e gases. The estimation of 255K is based on the earth’s long-term radiative equilibrium and Stefan-Boltzmann’s law which states…

The Collection of Evidence for a Lower Climate Sensitivity Continues to Grow – now up to 14 papers lower than IPCC

By Patrick J. Michaels and Paul C. “Chip” Knappenberger Nic Lewis and Judith Curry just published a blockbuster paper that pegs the earth’s equilibrium climate sensitivity—how much the earth’s average surface temperature is expected to rise in association with a doubling of the atmosphere’s carbon dioxide concentration—at 1.64°C (1.05°C to 4.05°C, 90% range), a value…
