There isn't enough fossil fuels in the ground for us to burn to cause a 20F+ increase in annual summer temperatures globally...

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.
