The visualizations below present two cases, from several different viewing positions: the 'world avoided' case, where the rate of CFC emission into the atmosphere is assumed to be that of the period before regulation, and the 'projected' case, which assumes the current rate of emission, post-regulation. Both cases extrapolate to the year 2065.

Brief Explanation for the Colors:
* Reds depict high concentration and dark blues show low concentrations of ozone. You can see the pulses of the ozone layer over the poles due to the seasons. The complete depletion is predicted by the 2050s if CFC had not been regulated.
