Short summary
At present, man-made halogens and natural oceanic substances both contribute to the observed ozone depletion. Emissions of the anthropogenic halogens have been reduced, whereas emissions of the natural substances are expected to increase in future climate due to anthropogenic activities affecting oceanic processes. We assess the impact of these oceanic substances on ozone by weighting their emissions with their potential to destroy ozone for current conditions and future projections.
