I thought about this and had an idea that I don't know if it can work, but I couldn't find any major problem with it.

Specifically, what if we start burying dead trees or those who reached peak mass in places where conditions will transform them into coal in 100(00..) of years?

That way carbon is captured and stored until we burn them again.

I am not sure that coal can be made this way again. There are fungi and bacteria now which break down the lignin in cellulose, which there was not during the carboniferous period. That was 60 million years of dead trees not breaking down fully and being compacted underground to make that coal, and it won't happen next time because the lignin will be eaten.

If deforestation is still occurring (net result that we are cutting down more trees than we are planting) then cutting down more trees doesn't solve the problem.

We do in fact need people to just start planting trees.

Of course. My point was to answer to the parent comment that said planting trees cannot be a long term solution.
