Unfortunately, this is one area human imagination and intuition fail. Trees are great, but the math shows they simply aren’t remotely viable as a means of bulk carbon sequestration.
I think you have to cut them down and bury them (or at least don’t burn them) for the carbon to “go away”.
That’s how it got underground to begin with.
Still until we actually 100% switch everything we could power off solar and wind to solar and wind, active carbon capture doesn’t make sense, sense we could use that clean energy for direct purposes instead of cleanup. I’m not sure we will ever have “excess energy” like that, we will always rather use it for something other than cleaning up our mess, like AI.
Basically, earth’s atmosphere was devoid of oxygen from its beginning, and it took billions of years to change that. it wasn’t until life had learned about photosynthesis before large amounts of oxygen started to accumulate in the atmosphere.
however, oxygen is a necessary prerequisite for most animal/fungus consumers, as they use oxygen to break down the organic materials. that is probably when major fossil fuel production stopped.
Nothing. You’re just asking trees to do something they’re not meant to do. Absorbing a single year of carbon emissions would require half the planet’s land area of trees. And that’s just while the trees are growing and absorbing a lot of carbon. Trees just aren’t efficient enough on a per acre basis to make a dent in carbon emissions, let alone capturing the carbon already in the atmosphere.

yes, you are correct, it makes more sense to focus on electrifying our big consumers first.
however, cleaning up could happen eventually. maybe some politician in the future will sell it as some “jobs program” or sth.
They were for several hundred million years. What changed?
The evolution of micro organisms capable of eating dead trees and emitting CO2 as a metabolic byproduct.
don’t forget the role that the Great Oxidation Event played in this.

What about sea weed? And sink it to the ocean floor?
