WebI have run two sets of experiments with the CESM model: The fully coupled model: pre-industrial control. 1%/year CO2 ramp scenario for 80 years. The slab ocean model: pre-industrial control with prescribed q-flux. 2xCO2 scenario run out to equilibrium. Our main first task is to compute the two canonical measures of climate sensitivity for this ... WebThe robustness of TCRE is tested using an Earth System Model (GFDL-ESM2G) forced with 7 different constant rates of carbon emissions (2 GtC/yr to 25 GtC/yr), including low emission rates that have been largely unexplored in previous studies. We find the range of TCRE resulting from varying emission pathways to be 0.76 to 1.04 ºC/TtC.
