And Bobby knew this shit like 20 years ago. It regularly gets into the low 100s in July and August in that region. It's not so terribly bad since it's dry heat, especially when there is wind. Arizona isn't even the highest risk area. The biggest issue in the US wet-bulb temps in the southeast.

The biggest issue in the US is wet-bulb temps in the southeast.

For people that aren’t aware, wetbulb temps essentially measure how well you can cool yourself down by sweating. Humid air means sweating is less effective since it can’t evaporate.

A wetbulb temp of 95°F (35°C) will kill someone in less than a workday if they’re not given proper breaks.

A wet bulb temp of 35°C will kill a healthy person sitting still in front of a fan.

Yeah, anything above 30°C (86 °F) is potentially fatal. 35°C is unsurvivable - and not something that happens naturally on Earth.

Yet.

It actually does! It’s not a hospitable environment, but large cave crystals form in these types of environments. 50 C, 90% humidity! cen.acs.org/physical-chemistry/geochemistry/…/i6
