Australian and US experts warn that super outbursts of fire thunderstorms could change the earth’s climate

Fire thunderstorms – which occur in pyrocumulonimbus clouds – not only create their own weather system, but can also be strong enough to actually change the climate, according to scientists from Australia and the United States.
- Fire thunderstorms during the Black Summer in Australia released as much energy as around 2,000 Hiroshima-sized atomic explosions
- Buildings of fire thunderstorms could be strong enough to change the climate, scientists say
- Measurement of the phenomenon as it occurs in North America and Australia was used to validate the “nuclear winter” theory
A “super-burst” of fire thunderstorms – also known as pyroCb events – during the Australian Black Summer Fires of 2019-20 released the energy of about 2,000 Hiroshima-sized nuclear weapons, according to a study recently published in the journal Nature Climate and Atmospheric Science .
“The energy released was just huge,” said Rick McRae of the University of New South Wales, a co-author of the paper.
“It doesn’t matter what units you use, they are big numbers, much bigger than we are used to handling.”
Mr. McRae and a team of researchers – including scientists from the U.S. Naval Research Laboratory in Washington – quantified the magnitude of the PyroCb super-eruption Black Summer and concluded that the fires injected as much smoke into the stratosphere as a medium-sized volcanic eruption. This smoke stayed in the stratosphere for more than a year.
Is fire now in a climate feedback loop?
According to McRae, fire thunderstorm super-bursts are now emerging as a potential feedback loop in the climate system.
He said climate change could lead to an increase in the frequency and intensity of extreme fire events, which in turn could change the climate.

I think this excuse for climate forecast failure is wise – it frames any pause or drop in global temperatures as a temporary reprieve caused by our negligent destruction of the planet, and builds on the long-term excuse that the global Temperature rise is predicted by the highly sensitive climate models is masked by aerosol pollution.
Aerosols have long been a convenient excuse, in my opinion, for why global temperatures have not risen. They allow climate scientists to increase their predictions of forced CO2 warming as long as they offset the predicted CO2 effect by increasing the predicted cooling effect of aerosols.
Of course, if global temperatures do indeed drop, it will be fascinating to see how long they can hold up such excuses with a grave expression.
