Fig. 4From: A review of progress towards understanding the transient global mean surface temperature response to radiative perturbationRelation between global mean surface air temperature and TOA net radiation changes from the preindustrial control simulation in the MIROC3.2 (medres) AOGCM experiments. Black crosses: 1pctCO2 experiment (every year for 1–140 years); blue crosses: abrutp4xCO2 experiment (every year for 1–150 years); red crosses: const4xCO2 experiment (every 20-year average for 141–3680 years); blue line: linear regression for the 150-year abrupt4xCO2 experiment; blue circles: equilibrium temperature response to 4xCO2 estimated by Gregory’s method for 10 abrupt4xCO2 20-year-long ensemble experiments (that start from different initial conditions in the preindustrial control simulation)Back to article page
