Antarctic Sea Ice Area in CMIP6
Fully coupled climate models have long shown a wide range of Antarctic sea ice states andevolution over the satellite era. Here, we present a high-level evaluation of Antarctic sea ice in 40 modelsfrom the most recent phase of the Coupled Model Intercomparison Project (CMIP6). Many models capturekey...

Fully coupled climate models have long shown a wide range of Antarctic sea ice states andevolution over the satellite era.

Many models capturekey characteristics of the mean seasonal cycle of sea ice area (SIA), but some simulate implausiblehistorical mean states compared to satellite observations, leading to large intermodel spread. Summer SIAis consistently biased low across the ensemble.
