Sweet Spots and Argiculture

This was posted on Watts Up With That.  I am re-posting because I agree, some some minor caveats.  The caveats are the sweet spots, those Goldilocks conditions that amaze, but tend to not last long.  There are cycles that are unavoidable and have to be adapted to when they arise.

Controlling soil carbon and moisture is key to limiting unwanted climate change.  Grasslands need grass and the herds are part of that cycle.  Forest need trees and glaciers need snow.  You can't convert everything to fields and parking lots and not expect climate change.  Got to find those sweet spots.
