Some scientists predict that climatic changes could alter historic precipitation patterns, and reduce available water supplies. Carbon dioxide loading of the atmosphere caused by fossil-fuel combustion, mostly in coal-burning power plants, threatens a significant climate change…. A National Academy of Sciences report estimates that the resulting temperature increase and reduction in precipitation could diminish water supplies by almost forty percent in the Upper Colorado Region.

OK, that was a few weeks ago, but you get my point. People have been talking about this for a very long time.
(I am so close to making some kind of joke comment about a quick turnaround in ideas after the 70’s, but maybe I should restrain myself in case other commenters take it seriously.)
And yet you pulled the joke off! (At least, I got it.)
