Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

I don't see how you're not getting this.
Yes, when you burn the trees you get electricity, but you also release as much carbon dioxide per kWh into the atmosphere as if you were to burn coal instead.
The climate does not care about where your carbon emissions come from. All carbon emissions are getting us further away from the holocene climate.
Maybe you're acting under the assumption that the trees wouldn't have grown or that they wouldn't have been cut down to make place for new trees if they hadn't been planned to be burned. Maybe that is even true under our fucked up capitalist economy. But that is just capitalism being stupid. If it is worth it to cut down trees to capture carbon, then we should fund that without also requiring the trees to be burned so all that progress is undone.
And sure, once the fossil fuel industry lies dead and atmospheric carbon dioxide concentrations are back below 280 ppm, then you can start burning biomass to keep the concentration stable. But that's a century from now. Before then, either bury the trees or don't cut them down in the first place.
Please recognise the difference between me not understanding you and me thinking that you are wrong.
All net emissions. If your process releases carbon at the end but captured the same amount of carbon at the start, you have not released any net carbon.
I'm acting under the assumption that they would have died anyway. As they do. When they decompose naturally, they release their carbon. Forests stop capturing more net carbon once they mature because they reach a point at which stuff is dying and releasing it as fast as new stuff is growing and capturing it.
The biggest problem with biomass is land use. In terms of area used per unit energy, it is terrible compared to basically every other option. Even hydro. This can be mitigated with good forestry practices, but it's a factor to be aware of and does rule biomass out as a really big contributor to a clean energy system.
Okay, glad to understand that the issue is that you didn't understand my first comment or any comment that came after it.
One last time: what I'm saying is that you bury the wood to prevent it from decomposing and releasing its carbon, as an alternative to burning it. And that as an alternate source of electricity you use something that doesn't produce as much emissions, like solar, wind, or nuclear. And if you think burying wood is bad for any reason, then setting it on fire is bad for the same reason.
At literally no point have I said burying wood is a good or bad idea, but I don't think we're going to see eye to eye here
On that we agree.
