Prescribed burns are used to reduce bushfire risk. A new study suggests it has the opposite effect (www.abc.net.au)

Interesting, certainly runs counter to prevailing narrative.

fix carbon anymore (yay fungi)

I've not made the time to get all up in my fungals, but i know a lot more understanding is coming out. Whats the deal?

For the rest of the thought, i've pictured it as a net loss, with a little uptake, a bit like the zoomed in hockey stick graph shows the yearly changes with the seasons. But i haven't any evidence to point to, if any exists.

For context, i live near bush and see the effects, so this all is just like, my opinion man... Ithink it retards growth, but there is definite regreening as you say, a lot though seems to be invasive weeds, so i don't know if the biomass actually increases that much. I suppose a tree ring study would show whether but offs effect biomass increase or noy.

So I might be wrong here, I have no formal training in the carbon cycle and am not nor have ever been a biologist but I was under the impression that coal basically no longer can be made as it comes from a time before lignin (the stuff what makes plants woody) could be broken down by organisms. Now, barring unusual geological events, plants die and fall into the soil where the vast majority of their substance is metabolised by fungi which use it for energy emitting co2 in the process.

So if you take some area and forest it, there is now a mass of carbon bound into plant stuff, but since it reaches a steady state quickly it isn't really sequestering any after that. This is why carbon capture is sort of a farce, as captured carbon in its ideal form is coal.

Oh gawd. Lignin and fungi i'd forgotten all about that. Biology was never my strong suit!

Yeah, i like your phrasing here. By no means a bad thing to promote, but not the simple silver bullet solution to net zero/GHG reduction the marketing departments of large emitting companies make it out to be.

My apologies I lied to you.

That information is wrong, coal is still being formed today. Although mostly in bogs, which provide an environment where decay doesn't happen.

About a million to 10 million times slower than we are using it though, and the rate is declining relatively as bogs are cleared or mined for peat/moss and our coal use increases year on year.

[–] Gorgritch_umie_killa@aussie.zone 1 points 1 week ago

All good! I thought about peet bogs, but its been so many years since i went through the formation of coal, i wasn't sure enough to suggest it.
