Global Warming Due to 2xCO2
qEstimated by computer models:
q      (1) Direct Greenhouse effect: warms up global surface temperature by 1.25°C
q      (2) Water vapor feedback produces another 2.5°C warming
q      (3) Snow-Albedo feedback produces another 0.6°C warming
q     (4) Cloud feedback is uncertain.
