Assume that ice albedo feedback gives a feedback parameter = 0.5 W/m 2 C. Estimate

Question:

Assume that ice albedo feedback gives a feedback parameter λ = 0.5 W/m2 C. Estimate the corresponding addition to the change in temperature under adoubling of atmospheric CO2 in the absence of other feedbacks. Assume that water vapor and the lapse rate feedback together contribute a feedback parameter λ = 1 W/m2 ◦C. Estimate the temperature change with this feedback alone, and compare to the combined temperature change when both feedbacks are included.
