NO This scientific assessment was prepared by hundreds of researchers examining the status and future recovery of the Earth’s protective stratospheric ozone layer. It reports that international controls on ozone-depleting substances are enabling gradual recovery of ozone concentrations towards conditions observed before significant depletion, with recovery expected around the middle of the century in many regions. The document outlines trends in atmospheric chemicals, noting declines in compounds formerly used in refrigeration, aerosols, insulation and fire suppression following global regulatory measures. It also explains interactions between ozone protection and climate processes, including the climate benefits of reducing ozone-depleting gases and the potential warming effects of substitute chemicals that are increasing in the atmosphere.
