Interesting, will read later. Odd that TX has the greatest depletion. As a NE resident, was under impression Ogallala was back to 2010 levels after 2012 drought hit it bad.
Technically our planet will be fine even if there is manure in human water supplies.
We could even go insane and nuke ourselves into oblivion by having every society launch every nuclear weapon at one another.
Even in the face of such a catastrophe the Earth would be here afterward. Albeit in a vastly different form that is incompatible with human life.
Climate change is basically our way of saying that the environment for human life is being adversely impacted. Doesn't really matter how because if we don't start to make the environment better for human life we won't be able to live on this planet any longer.
