I am not a global warming denier(although I think it is overhyped like most crisis in the world) but the heat in Australia this year is mostly due to the fucked up nature of El Niño over the past couple decades coupled with a peak in the solar cycle.
The real effects of global warming are actually very difficult to notice and the majority of climate experts expect less than a 1 degree(f not c) increase over the next 100 years(which has an impact but has very little to do with what you are experiencing).
