World Avoided Ozone Full Animation
This video is also available on our YouTube channel.
Led by NASA Goddard scientist Paul Newman, a team of atmospheric chemists simulated 'what might have been' if chlorofluorocarbons (CFCs) and similar ozone-depleting chemicals were not banned through the Montreal Protocol. The comprehensive model — including atmospheric chemical effects, wind changes, and solar radiation changes — simulated what would happen to global concentrations of stratospheric ozone if CFCs were continually added to the atmosphere.
The visualizations below present two cases: 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. This animation is an update to entry #3586, adding chlorine data and creating a Robinson projection of the ozone data.

NASA Helps Identify Uptick in Emissions of Ozone-Depleting Compounds
Read moreMusic: "Hidden Movement" Universal Production Music Complete transcript available. || NASA computer models help scientists identify an uptick in emissions of CFC-11, an ozone-depleting gas, in the atmosphere. NASA and NOAA work together, as part of a long-running research partnership, monitoring efforts on stratospheric ozone. This research continues their partnership, joining scientists from MIT and the University of Bristol. ||
