The past droughts in California described in that article are fully accepted in the scientific community. The recently ended drought is minor in contrast though of obvious impact to people there today. CA can expect and will get a truly devastating 100 year drought with nothing we can do to avert it as a normal course of natural climatic variation sometime in the future.
I was mocking the common phenomenon of ignoramuses posting some "revelation" as if actual experts are completely unaware of whatever gets time on fox news.
