Fires in Australia were preventable

Not at all. For Blédina all the fault lies with environmentalists, his pet peeve, his obsession, his whim ...

Australian fires of 2019 and 2020 generated huge swathes of phytoplankton in the Southern Ocean

A study published on September 15 in "Nature" shows that the iron transported in the ash plumes favored blooms of microalgae that could influence the climate.

In one sense, the bad news is that CO2 emissions had been underestimated

The extreme bushfires that blazed across southeast Australia in late 2019 and early 2020 released 715 million tonnes of carbon dioxide into the air, more than double the previously estimated emissions from satellite data, according to an analysis.1 published today in Nature ... Bowman says the figure is similar to what his team calculated from the area of ​​forest burnt3, but much higher than the numbers based on previous satellite emissions measurements.

On the other hand, part of the smoke was used to feed phytoplankton

Within days, these aerosols had infused the waters with much-needed iron, nourishing phytoplankton, which absorbed the carbon equivalent of 95% of fire emissions.

The ocean seems to perform "an incredible sleight of hand - like a magician," Bowman says. But he and other researchers say more work needs to be done to understand where the carbon occupied by plankton ends up going, and whether it returns it to the atmosphere. https://www.nature.com/articles/d41586-021-02509-3

You just have to spray huge cold and poor areas with iron to detonate the phytoplankton which will absorb huge amounts of Co2 and produce food for the entire food chain and oxygen for the atmosphere. This NATURAL mechanism is impressive in efficiency (95% of the Co2 produced by Australian fires absorbed) !!!
There's no need to say, nature is really shit ...

i.e. 0,7 Gt CO2, while anthropogenic emissions are around 30 Gt per year and the biosphere annually exchanges 200 Gt in both directions ... depending on how you write it, it still doesn't give same feeling

In the longer term, the results will be zero since of course the forest will eventually grow back, it has seen others ... and will burn again. To push back then.

It is big shit and scientific swindle (pro fossil, pro lobby ...) to consider fossil and plant CO2 emissions on the same table ... Already said many times above and elsewhere on this forum...

On this coup agree with ABC ... So ...

I doubted that you would have bounced on this detail ... which only concerns the opinion of a researcher without any relativity, which is that of fallout at sea, the vast majority of this oxidized gas must have joined the atmosphere for a long time, amplifying GHGs. This is only a press article, scientific articles are more precise but "reserved for specialists".

I can give you another detail of the article which is the most important

Wildfires have long been considered net zero carbon events, as the emissions they release are recaptured as vegetation grows back - but an increase in the frequency and intensity of fires in Australia could mean that ecosystems never fully rebound. If these fires "threaten the recovery of the ecosystem, then we really have to worry," she says.

It is however the same molecule

On this coup agree with ABC ... So ...

I wonder who would have thought otherwise

Only for those who do not know how to make an eco-balance sheet correctly and who should do their self-assessment!

Who are those who know?
It can only be done on a global scale for atmospheric CO2. It's the job of https://www.ncdc.noaa.gov/global-warmin ... 2000-years, Among others.

After that depends on what we talk about.
If we focus on agricultural soils, there is potential to store if we really want to.
