Recent work with coupled climate models has suggested that Antarctic sea ice has a two timescale response to stratospheric ozone loss, with a short term increase but a longer term decline. Here we explore this relationship in a large set of simulations from the Community Earth System Model and in other models participating in the Coupled Model Intercomparison Project. We find that the strength of the long-term sea ice response relationship varies considerably across climate models and find evidence that this influences their late 20th century Antarctic sea ice trends.
