You're using the word soaring with Death Valley that has a long history of 50C+ temperatures. It may be more frequent, but hardly soaring. I'm not sure what local is in this context either, but Death Valley has a particular geography that helps it reach such high temperatures that aren't present in the surrounding areas. If you're worried about people living in this region, then looking at Death Valley isn't a good indicator. There is a long history of farming less than 100 miles away and that really isn't threatened.
