Hi everyone today i will research on how the whole world has avoided controling or they are not preventing the Ozone layer they are just destroying it. Newman and colleagues set out to predict ozone losses as if nothing had been done to stop them. The team started with the Goddard Earth Observing System Chemistry-Climate Model, an earth system model of atmospheric circulation that accounts for variations in solar energy, atmospheric chemical reactions, temperature changes and winds, and interactions between the stratosphere, where ozone is found, and the troposphere, the layer of atmosphere closest to Earth. Their “world avoided” process that it took months of computer time to process.
The researchers let global emissions of CFCs and similar compounds in the model world increase by 3 percent per year, the rate at which they were growing before regulation in the late 1980s. Then they let the simulated world turn from 1975 to 2065.
