Futurology

Yeah, just get a good ecosystem going and every now and then, collect extra decaying matter and dump it in deep landfills to further reduce carbon escape. Hopefully the pit will be deep enough to stop the decay and prevent instant (in geological terms) biogas formation.

Ok, I guess that is not very viable. Just go with normal forests then. But that won't match the predicted numbers because predictions didn't consider reduction of net Carbon -ive of the forests as they came closer to equilibrium.

We need way more trees than we previously thought, way sooner than we previously thought. Now, even more since the average temps have already increased, further changing the forest efficiency.
