@shoshin Npt sure where this guy is getting his info from. New trees sequester carbon at a greater rate than old trees since they grow faster where old trees of most species tend to not really get bigger very fast at all. Yes a small sapling in the first few years wont sequester very much at all that quickly accelerates in a logistic like curve.

The way to sequester the largest quantity of carbon is to cut down old growth and constantly replace it with new growth every 50 years or so.

Now im not saying we should cut down all old forests, there are concerns other than CO2 at play here. But if we are talking about CO2 then the comments here are misleading.
