Extending the PAMIP protocol for assessing the climate response to regional sea ice change across all Arctic regions
Climate models predict that sea ice cover will shrink--even disappear-- in most regions of the Arctic basin by the end of the century, inducing local and remote responses in the surface climate via dynamical changes in the atmospheric circulation. The atmospheric-only experiment designed and perform...
