Do you mean Canada, which is increasingly on fire? Or do you mean Scandinavia, which will become a glacier once the atlantic current shuts down next decade? Or do you mean Siberia, which currently has a record high temperature of 38C and everything is turning into a molten swamp? Or do you mean Arkhangelsk where the ecosystem will collapse because everything expects permafrost?
Do you mean any coastal city, which will flood? Do you mean places supplied by the international trade network? Do you mean places that expect the sea to contain living creatures? Do you mean places that are dependent on crops that expect temperatures to swing less than 25C back and forth in a week? Do you mean places that are open to the sky and aren't prepared for hurricane winds?
And if there is a place you've found that can weather the storm - do you mean the places where 8 billion people will try to get to but that only have room for less than 200 million total?
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.
