If one wants to look at the broader situation, at least in the US, there is the US Drought Monitor Map, which tracks the drought / dry situation, week by week, for months.
Clearly, the US Southwest is generally getting MUCH worse than the long term averages would predict.
CA is bad, but far from the worst.
https://droughtmonitor.unl.edu/Now, how bad does the overall map need to get before society generally, or the Current POTUS admin, etc. is willing to acknowledge that there's a significant problem?
"Significant" enough to risk losing an election over (re actually DOING SOMETHING ABOUT IT, via modified policy -- which in the US is FAR from often enough, considering how politics on BOTH sides, generally works.
Given the track record of the perma-doomer blogs, I wouldn't bet a fast crash doomer's money on their predictions.
