Updated: Low Climate Sensitivity Estimated from the 11-Year Cycle in Total Solar Irradiance

Roy W. Spencer, Ph. D.
"I think the methodology I have presented is the most physically-based and easiest way to estimate climate sensitivity from the 11-year cycle in solar flux averaged over the Earth, and the resulting 11-year cycle in global surface temperatures. It conserves energy, and makes no assumptions about the temperature being in equilibrium with the forcing. "
