Charney climate sensitivity
WebThe concept of climate sensitivity described in this report, sometimes called the "Charney Sensitivity", envisions the equilibrium sensitivity of Earth's climate to forcing as the equilibrium response of the climate system to a doubling of concentrations including all fast feedbacks —that includes changes in water vapor, clouds, sea ice, and …
