Steady erosion of Earth’s protective ozone layer has occurred during the past several decades, associated with emissions of industrially produced CFCs (chlorofluorocarbons). International legislation has essentially banned the production of CFCs, which should lead to recovery of the ozone layer in 50 to 100 years. Recently, scientists have found that subtle changes in Earth’s climate may also play a role in ozone depletion.

This talk will examine future prospects for Earth’s ozone layer, drawing upon research activities at JPL and Caltech in the three “pillars” of atmospheric sciences — laboratory measurements, atmospheric observations, and computer modeling.
