The Antarctic ozone hole is about one-third to blame for Australia's recent series of droughts, scientists say.

Writing in the journal Science, they conclude that the hole has shifted wind and rainfall patterns right across the Southern Hemisphere, even the tropics.

"The ozone hole results in a southward shift of the high-latitude circulation - and the whole tropical circulation shifts southwards too," explained Columbia's Sarah Kang.

Of particular interest was the southward migration of the Southern Hemisphere jet stream.
Interesting, though admittedly, I don't quite understand all of it (get the jet stream and stuff sort of, but not that well versed in well much of any science :P). If you read on, apparently they feel that this Ozone hole, combined with natural cycles and greenhouse gasses, is causing the drought issue with Australia.

Obviously this isn't much of a debate piece, but figured it was interesting information for anyone curious.
