Bush fires, Australia and climate change : Comments
By Charles Essery, published 2/1/2020Climate change has reached cult status and with the lemming-like adoration of characters like Greta et al, backburning is judged only to increase CO2 and therefore to be outcast.

And all down to increased CO2 already at record uncharted levels as a proportion of the atmosphere!
And the annual burns that the arsonists love does add more CO2 to the atmosphere even if those fires are cool. And also with every burn, scarce soil nutrients go up in smoke and out to sea never to return, where they do nothing but harm to the natural environment and balance!
We know this as fact due to the loss of tonnage in sugar cane that is burnt just before harvest, as a year in year out, result!
How long have we grown cane in this country? Imagine if we'd grown it for forty thousand years! Why the cane fields would be barren arid wasteland!
Not only that but repeated annual burnings bake the ground over time with the result more runoff and less penetration of available moisture.
Fuel reduction which is an absolute essential is done far better with very short term, intensive herd grazing, which has the effect of chopping up hardened ground to allow better penetration of rainfall and less runoff and with that, less erosion.
Add dung beetles and all the organic material that comes with intensive short term call grazing is added to the soil as increased carbon that also adds to its ability to retain moisture.
If management teaches us anything? It teaches us there is always a better way and that way is neither black or white, just a right way!
