Seminar Abstract:

Antarctic stratospheric ozone depletion (“the ozone hole”) has been a recurring human caused environmental impact for more than 30 years. Thanks to the phase-out of many of the chemicals responsible for stratospheric ozone depletion in the 1980’s and 1990’s we should start to see a recovery in the ozone layer over the current decade, and we are looking for the first signs of this environmental success. We will present some recent measurements from inside the ozone hole, discuss its current state, and address the forecasts and challenges for a complete recovery of the ozone hole.
