Recent EOS article highlights what a little chemistry, meteorology, and billions of dollars in satellite remote sensing can do. Cant link to the article so I searched for this less than perfect article:

The ozone hole will recover in 2068, and signals for this recovery may not be visible until 2018.
This problem is similar to what we see with CO2. Add now, deal with it for decades to centuries.
Remember, we turned off most ozone depleting chemicals, but it will still take another 59 years for recovery. Is it any wonder that most scientists agree that global warming is for real? The time scale may be large and the effects seemingly small for now, but add a hundred years and there will be serious climate changes.
