"Seriously though, anyone care to do the math on the impact of 1bn trees wrt. CO2 absorption?"
That should be a fairly simple calculation, as children to your post have shown ...
More interesting (and difficult) is the carbon costs of actually planting the trees in the first place ... 40% of the trees were saplings[1] that were moved and planted with labor that was fed and moved, etc.
I have no idea how those figures pencil out - if the best-case absorption is 1.5 lbs/tree per year, is it obvious that less than 100-150 lbs of carbon is spent in planting the tree ?
