Join Professor Darryn Waugh from Johns Hopkins University and UNSW for an enlightening discussion around the enduring impact of the ozone hole on climate.
The discovery of a dramatic decrease in the protective ozone layer high above Antarctica generated worldwide concern and ultimately led to the landmark 1987 Montreal Protocol banning ozone-depleting chemicals. While the initial focus on the ozone hole was increased UV radiation reaching the surface, more recently it has become clear that the ozone hole may have an impact on other aspects of the atmosphere-ocean climate system.
Darryn will discuss recent observed changes in southern hemisphere tropospheric and ocean circulations, and the connection to the ozone hole.
He will also examine simulated future changes, and when ozone is expected to recover.
