According to Tim Flannery’s Climate Council, Aborigines ate the megafauna, so highly flammable scrub grew up and they had to develop hazard reduction burning. Then the Industrial Revolution changed our climate so that it’s impossible to do mild burning, and now we get extreme weather that creates unstoppable megafires. 

On the other hand, according to Scott Mooney and eighteen other scientists, Aborigines had no effect on Australian fire regimes which varied according to the climate in Greenland (this is not a typo) as evident in ice cores. They say that more biomass burnt in warmer periods and human influence on fire regimes began after Europeans arrived in Australia. 

Objective scientific analysis of the relevant data reveals that both views...
