Oh no Ozone!

My old pal NASA has a great resource for looking at the hole in the ozone over Antarctica.   They have daily images of the hole, which was at its largest in September 2006.   The ozone has actually begun to shrunk again, and what I love about this website is that they have piled the images together in an animation that you can show your students.  This website also shows a projection for what our ozone would have looked like if CFCs hadn’t been banned.   I think it makes a great   impact to talk about how humans created the ozone hole with CFCs but we have also begun to shrink it, with our efforts.   It shows that we can make a difference in our atmosphere.
