Between 1955 and 2000 stratospheric ozone decreased and tropospheric ozone increased. Model analysis shows that these ozone changes each drove warming of the Southern Ocean through distinct mechanisms and together account for ~30% of the net subsurface Southern Ocean heat content increases over the same period, with the larger contribution from tropospheric increases.
