Well, there is the Indian Ocean Dipole thing at play as well. Hopefully that won't last forever and we'll see rain next winter. Some australian vegetation reacts weirdly well to fire and bounces back within a few years. Not sure this will be the case in this event though, with the extraordinary heat the fires generated their own weather systems etc, also any old growth is lost mostly.
And as some of those areas haven't seen rain for up to four years, there is no reason to think they will see much rain after this event either.
So we're looking at a few million HA more of desert developing in the next decade. Areas that will no longer be able to capture any CO2.
