Someone needs to clue this clown in the recorded history of the state of California isn’t that long a time period.
Let’s go back a few thousand years.
There is also the fact that California ranks as the 4th driest state and is among the most populated.
Actually, I think the author made that point - that this is the worst drought in the history of the state of California - but California has only been a state for a little over a century and a half. The author makes the point that the 20th century saw an unusually high level of precipitation for the region. Using proxy data (growth ring data from old-growth trees, etc.), it becomes clear that drought is the normal condition for California. In fact, in the last millenia or so, California has had droughts that lasted decades, and in one case, centuries.
