A recent AP News press release featured ESSIC Professor Ross Salawitch for his recent United Nations report, “Scientific Assessment of Ozone Depletion: 2018”.
The report states that Earth’s ozone layer is finally healing from damage caused by aerosol sprays and coolants. AP News details the history of the infamous “ozone hole”, asking Salawitch how this healing will affect climate change.
Salawitch reports that the ozone hole has actually shielded Antarctica from some of the larger effects of global warming— Antarctica has heated up, but not as much as it would without ozone depletion.
Salawitch is a professor in UMD’s Department of Atmospheric & Oceanic Science and the Department of Chemistry and Biochemistry. His research focuses on quantification of the effects of human activity on atmospheric composition with major topics of current interest are stratospheric ozone depletion and recovery, air quality, and the global carbon cycle.
