Nobody is outside much at those temperatures. Especially over 40C - even fully covered, with breathable wicking clothes, which historically would be normal, in the ME, you'd best be drinking and sweating a lot, to stay cool. If not, it could be deadly.
Also, temperatures don't cause sunburn, but heatstroke. So, WTF does that have to do with anything? Sunburn is about UV-B overexposure, mostly, and which skin pigmentation is a very good proxy for resistance or sensitivity to that.
You can get seriously sunburned when it's only about 80F/27C, on a a UV heavy day (which have been getting more common, lately, as Earth's EM field has been weakening). As a descendant of mostly central and western Europeans, I know first hand.
