These fire tornadoes have also been seen in recent California wildfires.....just another indicator that the extremely dry forests and soils created by global warming are changing wildfire behavior in ways that make them even more dangerous.
Please explain the fact they have been documented back in the twenties (as my post points out above) and that this is then related to "climate change". As pointed out the fuel issue is all about fire management and much less about climate change. If you have a hot year (as Australia had back in the thirties continuously) as long as there is a plan to deal with the tinder large fires are generally controllable. Australia has a problem with fuel management and is susceptible to fires...put two and two together.
Sensationalism might sell to the public but the fact of the matter is this phenomenon has been around as long as large wildfires have been present (we are talking about Australia so please explain the huge fires in the late 1800's).
But go ahead, ignore all the folks who have lived down there for decades and understand the issues (as my post above points to). Just invoke the old any reason to blame it on climate change is a good thing to do argument.
