Record Southern Ocean sea ice extent is (very likely) caused by a combination of changing wind patterns (which acts to spread rather than aggregate the surface ice), and changes in the rate of overturning, which leads to stratification of sea-surface temperature layers. The greater ice extent is NOT a signal that the Southern Ocean is cooling -- it is unequivocally warming, as revealed by ARGO and satellite measurements, and indeed is considered the flywheel of the climate system.
