2012b: Mitigation of 21st century Antarctic sea ice loss by stratospheric ozone recovery
[1] We investigate the effect of stratospheric ozone recovery on Antarctic sea ice in the next half-century, by comparing two ensembles of integrations of the Whole Atmosphere Community Climate Model, from 2001 to 2065. One ensemble is performed by specifying all forcings as per the Representative C...
