International Treaty Designed to Restore/Protect Ozone Layer Working, Say Scientists: "Countries world wide have controlled the production and use of ozone-eating chlorine compounds, and the Earth's atmosphere appears to be recovering from losses of 'good' ozone in the upper reaches of the atmosphere. These findings were published in the journal Nature. A paper by Betsy Weatherhead, a scientist working at the NOAA Earth System Research Laboratory in Boulder, Colo., and Signe Bech Andersen, of the Danish Meteorological Institute details an apparent leveling off of ozone loss as a result of the Montreal Protocol. This international agreement was first enacted in 1987 to control ozone-depleting chemicals in the atmosphere and was since signed by 180 countries."
