Hmmm. I don't know, the process described in that third article sounds like a perfectly reasonable bit of building better tools. Even if we can't be certain what the ozone layer looked like, say, 80 years ago, predicting the progress of reversal of damage that we've actually observed should be possible. (I'm not sure it'd even be a factor, really.) Whether this set of predictions will be right... well, time will tell.

Alas, that's the easy part. Figuring out what things would look like without these chemicals around is a much more difficult problem. And one more difficult to prove than any on ozone recovery - for that we just have to wait.

And while I'm asking questions. Hey, Necratoid, do you think reducing the use of CFCs is a bad idea?

Quote:... Okay. Why is there so much less depletion over the US, where we presumably have been releasing all sorts of CFCs and things? I can't believe someone hasn't come up with an answer.
"The Antarctic ozone hole is the poster child of ozone loss in our atmosphere," said author Paul Newman, a research scientist at NASA's Goddard Space Flight Center, Greenbelt, Md. And lead author of the study. "Over areas that are farther from the poles like Africa or the U.S., the levels of ozone are only three to six percent below natural levels. Over Antarctica, ozone levels are 70 percent lower in the spring. This new method allows us to more accurately estimate ozone-depleting gases over Antarctica, and how they will decrease over time, reducing the ozone hole area."
