The megadrought California is enduring right now is the worst in more than a millennium.

In the last two decades, we have only sporadically not been in a state of drought, and the first three months of 2022 were the driest on record. Now, nearly every inch of California is experiencing severe or extreme drought, or even worse: A thick, donut-shaped ring in the Central Valley is in an exceptional drought — the highest drought designation the U.S. Drought Monitor gives.
