>if you drink enough water it’s no problem If you learned such a thing you learned incorrectly. Mojave is dry. The article mentions this, but the relevant measure is the "wet-bulb temperature", which combines heat and humidity. The name comes from the technique of wrapping a thermometer in a water soaked cloth and passing air over it, so that it takes into account evaporation. Thus the wet-bulb temperature is the lowest temperature that can be reached through evaporative cooling alone. No matter how much adaption you have to the heat, nobody can exercise and do normal (let alone strenuous) continuous outdoor activity with a wet-bulb of 90°F or so, and ~95°F wet-bulb is about the absolute limit of how much a human can survive longterm (ie., someone could still last an hour or two), even just lying in the shade. No amount of water you drink can help you if the air is at saturation already. So there is genuine concern that parts of the world will literally become uninhabitable without universal mechanized cooling or other extreme adaptive measures (going underground say). And while the general focus is humans, of course every other animal is the same plus or minus some number of degrees.
