9 of the next 10 days in Dallas would be on that list. 3 days from last year in Seattle would be in the top 5 days on that list.
We are comparable to the extremes of a coastal eastern city, with significantly lower temperatures between the peaks. There’s not many places in the US that have never seen 106.
As for water, 80%+ of it in California is used for food that is exported elsewhere.
Strawberries in December in New York are much more at risk than humans in CA.
As for fires, nowhere in the world is safe from that, as this summer is proving.
And this isn’t to mention the wildfires or inevitable water issues.
