According to my calculations and
estimates, the number of individuals around Australia whose arson has
contributed to the current bushfire crisis has now passed 200.

This figure is not presented as a
counter-argument to those who blame the fires on climate change. Most
people (I hope) understand that trees tend not to spontaneously combust,
no matter what the air temperature is; when we talk about bushfires
starting naturally, we are talking about lightning strikes igniting
tinder. The climate change argument posits that the more extreme weather
conditions – higher temperatures, drought and so forth – make fires,
however started, much more destructive and much more difficult to
control and extinguish. These are debates to be had between
climatologists, forestry experts and firefighters.
