Extended Data Figure 5: Surface albedo map used for the Earth baseline case.
From: Increased insolation threshold for runaway greenhouse processes on Earth-like planets
This map does not include the effect of the ice albedo, which is computed directly by the GCM. The albedo of Greenland and Antarctica, in particular, was set to 0.35. The altitude of these regions was, however, left unchanged, explaining in part the temperature contrasts around these areas in Fig. 1.
