22. 2O abundances and surface temperature were performed at intervals of 50 My for the results shown here; for a similar model (11) a time step of 25 My yielded temperature variations within 1 to 2% of those with a 50-My time step. At each time step, and hence atmospheric composition, the state of the clouds and the radiative-convective equilibrium temperature structure of the atmosphere was determined with the coupled model for clouds and atmospheric radiative transfer.

28. j implies summation over i from 1 to n. This climate-driven variation in internal temperature will be superposed on the steady increase in temperature with increasing depth associated with long-term heat flow from the planetary interior.

33. 2O as in the model of Fig. 2 results in temperature excursions that are slightly smaller in magnitude (the early warming is by 45 K instead of 60 K). The rapid loss of clouds and subsequent cooling occurs about 100 My sooner than in Fig. 2.
