Their argument is not predicated on a 20F+ temp rise globally; their argument is about regions.

Most of the increase in local temperatures are overnight lows in the Winter. I'm not sure there's any peer-reviewed mechanism to suggest that daytime Summer highs will increase 20F+ due to greenhouse gases in any parts of the world.

So your argument that this statement by them: "If you live in a region that usually was 90F in the summer and is now >110F regularly, that’s going to cause problem." is hyperbole, then? Okay, going with that, what temperature range would you find credible, as to describe a region that is seeing wilder swings in summer highs?

Somewhere on the order of 1-2C if you start from the 1850s.

		I'm not talking about global, look at individual countries: - Andora (5C/9F) - Montenegro (5C/9F) - Japan (4C/7F) - Italy (4C/7F) - Spain (3C/5.4F) Even with current rates I think we'll easily hit a 20F increase in several regions.
