From: General circulation and global heat transport in a quadrupling CO2 pulse experiment
Time series obtained from 4 × CO2PLS experiment for (a) atmospheric CO2 concentrations, (b) deviations in the global mean surface air temperature (GMST) and hemisphere-averaged surface air temperature, (c) deviations in global mean potential temperature in the upper and lower oceans, (d) deviations in hemisphere-averaged potential temperature in the upper and lower oceans, from corresponding means of the pre-industrial runs. (e–h) As in (a–d), respectively, for 4 × CO2CDR experiment. Blue and red shaded portions indicate 50-year periods when forcing was switched on (ON50Y) and off (OFF50Y) for (a–d), respectively, and ramp-up and ramp-down periods for (e–h), respectively. Units are represented on the scales in each panel.
