A new study claims that, by the end of this century, some cities in the Persian Gulf will be uninhabitable by humans, thanks to extreme temperatures up to 170F (76c).
The abstract of the study:
"A human body may be able to adapt to extremes of dry-bulb temperature (commonly referred to as simply temperature) through perspiration and associated evaporative cooling provided that the wet-bulb temperature (a combined measure of temperature and humidity or degree of ‘mugginess’) remains below a threshold of 35 °C. (ref. 1). This threshold defines a limit of survivability for a fit human under well-ventilated outdoor conditions and is lower for most people. We project using an ensemble of high-resolution regional climate model simulations that extremes of wet-bulb temperature in the region around the Arabian Gulf are likely to approach and exceed this critical threshold under the business-as-usual scenario of future greenhouse gas concentrations. Our results expose a specific regional hotspot where climate change, in the absence of significant mitigation, is likely to severely impact human habitability in the future."
According to Wikipedia, the hottest temperature ever recorded was 57c (134F) in Death Valley, in 1913. 76c (170F) might not seem like much of a leap from 57c, but the cities Doha, Abu Dhabi and Bandar Abbas are all coastal cities which experience substantial Summer rainfall.
Summer rainfall and storms are natural air conditioning. When temperatures soar, evaporation, convection and storm activity remove vast amounts of excess heat from the surface and transport the heat straight up to the edge of space. The heat laden water vapour keeps rising until it condenses – the vapour simply punches straight through the bulk of the world’s greenhouse blanket, soaring into the upper reaches of the troposphere, until it finds a height at which it can dump its vast store of heat.
Anyone who has spent time in the tropics, who has seen the towering thunderheads which form in Summer, has experienced this cooling phenomenon in action. The air is always very perceptibly cooler after a major thunderstorm.
Abhu Dhabi, Bandar Abbas and Doha aren’t going to run out of “coolant” – as coastal cities, any evaporation is immediately replaced from the inexhaustible waters of the world’s oceans.
If the world warms, what is surely more likely than implausibly high maximum heatwave temperatures, is that the temperature would stay about the same, but Summer rainfall would increase.

I’ve read at least one scare piece saying it’ll be so hot the Muslims won’t be able to make the hajj to Mecca. Fail to see the downside, though! ;)
That was my overall reaction. Not that I think it likely, given the track record of the Warmist Alarmists for prognostication.
Anyone know how far from ground zero it would have to be, for the heat wave to have cooled to only 170?
We have more immediate problems. If we don’t close the ozone hole, we might all be dead by the year 2000. Oh wait..
They say that like it is a bad thing...
Senator Blutarski is right about the concentration of heat but that misses the point. The solution to this is so simple that no one can see it. All they need to do is contact the people who calculate the CPI figures and learn how to change the method of calculating temperature so that the temperature comes out to what you want it to be. Why go off on a wild tangent and complicate things unnecessarily? I am installing a limited range thermometer at my location so that the temp cannot go below forty or above seventy degrees F at any time. I got the idea by studying the latest figures on unemployment.
Bring back the use of CFC’s and that will reopen the hole in the ozone layer to let all the heat out; problem solved. Sarc/
