ERROR! ERROR! EXAMINE!!
So many errors and falsifications to know where to begin.
The the most prominent greenhouse gas is not carbon dioxide it is water vapor.
The unsubstantiated assumption of how many farmers died is the basis for how much farmland was reforested which is used to estimate how much carbon was sequestered by reforestation.
This whole article is a house of cards supported by unfounded assumptions.
I can only guess that by ‘prominent’ they mean press coverage, not reality.
Good catch!
(I used to like reading Scientific American 30 years ago - it’s still published these days?)
