Ten times the fuel means 100 times the intensity
Hardly anyone is talking about these numbers yet they show just how far beyond our control the pyroconvective firestorms are and why we need to be so much smarter at preventing them. They also show how irrelevant temperatures onsite are, compared to fuel load and wind speed.
Controllable fires are 3MW per meter, but we now have loads of 70MW/m
Not only are these fires obscenely, catastrophically intense, it doesn’t matter how much fire fighting equipment we buy, how many dams we empty, they are a man-made disaster, and we’ve known for years how to prevent them. (Some would say, thousands of years). The message in here is that cool controllable burns are tiny, less damaging, and far less intense. The pyroconvective monsters are totally different creatures.
Andrew Bolt interviewed fire expert David Packham in November:
Top fire expert David Packham says forget global warming. It’s the reckless failure to burn-off fuel loads that have turned parts of Australia into death traps. Near Melbourne “we’re looking down the barrel in these areas at 1000 deaths”.
His key point is that if we increase the fuel by ten, […]
