Cloud cover modeling is, or was last I checked, wholly inadequate. It seems entirely possible we could tip over into an ice age. If the whole planet became shrouded in fog, insolation would be reflected back without being converted to IR first, so not trapped by CO2. As temperature falls, ice spreads from the poles. Cloud cover dissipates. Ice takes up the job of reflecting insolation. Brrrr.
