For edge cases around both stars, the outgoing longwave radiation (left column) for the cold planet scenarios is blocked by the presence of CO2 clouds, which dominate the influence of H2O clouds (Figure 3). For the potentially habitable scenarios, the lack of CO2 clouds has the opposite effect. Habitable planets are substantially darker than nonhabitable planets (right column) due to the lower albedo of the ocean compared to the highly reflective H2O and CO2 ices and differences in cloud cover.
