1% CO2 forcing: FAMOUS vs. HadCM3
From experiments with instantaneous increases to 4xCO2, we know that XDBUA’s climate sensitivity (as specified by Gregory et al., GRL 31 (2004)) is 1.10±0.09W/m^2, compared to 1.32±0.08W/m^2 for HadCM3. ADTAN, or XBYVS were 0.89±0.07W/m^2.
A 1%/yr CO2 increase scenario has also been run. Plots showing changes in surface temperature (deg C) and precipitation (mm/day) after 100 years are given below.
