compared to when TSI is reduced, with snowball states not simulated for the MAR and RECT
geographies through CO 2 reduction alone with TSI fixed at 94%. Similarly, ice-free states are
more readily simulated with CO 2 increases compared to TSI increases for the same global
forcing. This trend is principally related to the zonal pattern of radiative forcing induced by each
method of altering … Cloud fractions are highest over regions of vigorous convection over the …
