WebAug 11, 2011 · “Global climate sensitivity including the slow surface albedo feedback is 1.5oC per wm-2 or 6oC for doubled CO2, twice as large as the Charney fast-feedback sensitivity.” This “Hansen Upgrade” is represented by the green line on the semi-log (base 2) scale. The sensitivity of 6oC for a doubling of CO2 yields an Amplification Factor of 5.0. WebThe Charney Sensitivity indicates about 3°C warming for a doubling of CO₂. We can expect about 1.5°C warming from our current level of CO₂. At 440 ppm CO₂ we should expect about 2°C ...
