The observational records from MISR and CERES on the Terra satellite, from 2000 to present, are still too short to be definitive of long-term change. They do, however, show interesting hints of competing trends due to changes in cloud properties — effective height and albedo —that occur at different latitudes and do not necessarily cancel. If either effect ultimately dominates, it will alter the long-term rate of change of surface temperature. I’ll discuss the observational evidence for these changes, examine their potential net effect using a new radiative-convective equilibrium climate model, and note some of the challenges for future modeling.
