Ozone and climate: a review of interconnections

Stratospheric ozone has been depleted over the last 25 years following anthropogenic emissions of a number of chlorine- and bromine-containing compounds (ozone-depleting substances, ODSs), which are now regulated under the Montreal Protocol. The Protocol has been effective in controlling the net growth of these compounds in the atmosphere. As chlorine and bromine slowly decrease in the future, ozone levels are expected to increase in the coming decades, although the evolution will also depend on the changing climate system
