Alek Petty from the Earth Sciences Department will be discussing why we see an increase in Antarctic sea ice cover despite the increasing effects of climate change.

The Arctic sea ice cover has experienced a rapid decrease in extent and thickness over recent decades. In contrast, the Antarctic sea ice cover has experienced a small increase. Current understanding of Antarctic sea ice is limited, however the recent sea ice trends have been linked to regional trends in the winds surrounding Antarctica. The contribution from anthropogenic climate change and the Antarctic ozone hole is still poorly understood, with natural variability probably playing a considerable role. Antarctic sea ice is a crucial component of the Earth’s climate system, so improved understanding is urgently required.
