Thanks for sharing. I think without being able to compare this study to results from the same region over years, it could be difficult to pin this on our damaged ozone (i.e., maybe this has always been happening, and this is just the first study of its kind...?). The article doesn't make that very clear... regardless, the study in itself is interesting and upsetting.
