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