That's the part you don't get. The "right conditions" are spreading far and wide due to climate change.
Australia has been in a drought for a long time. It's not the first time that's happened and it won't be the last. It's got nothing to do with GW/CC/CD!
Does the exclamation mark make it true?
Australia hasn't been in drought for very long, by historical Australian standards. What's different the last few years is that it's been hotter, rather than drier, leading to big fuel loads and higher fire dangers on the hottest days - which are hotter, more common, and less widely separated.
The weather pattern we are seeing is exactly that predicted a decade ago to occur around now, due to climate change. Angry denials and the use of exclamation marks by demonstrably ignorant Internet users don't do much to counter a prediction that frighteningly accurate.
