big snip
Then one day somewhere hits 40.1C. I'm wondering if it is worth a
bet? What odds would the bookies give now on such an event?

I'd want odds of 20-1 before I'd consider a bet. 40C would be a big
increase over the current record, not just a few tenths of a degree but
about two whole degrees. It will probably be reached one day, but I
suspect not just yet.
