Peoples struggling with hot buildings overnight, evaporation takes energy and will cool your building, even a light spray of water on your exterior (especially concrete/paving patios) will help cool you down overnight #BuildingScience

Update on keeping cool. If you have water shortages, do the evaporation trick on your body. Wet a cloth, wring it out and put it around you. I have a sarong that I used wrap around me in the desert. Everyday was about 45 deg C. As @skribe pointed out, this does not work as well in humid places.

This is the stuff of my recurring nightmares. Sometime in my lifetime, somewhere well populated will reach wet bulb 35c. This means that evaporation temp you are getting to is so high it doesn't cool us down. A healthy adult male is projected to survive 6 hours in that.

My recurring dream is that I'm somewhere in the mid east and walk out of a hotel room to see street after street of bodies of people who didn't survive the night.

@chu @SeaFury we already get days of that here. 15 or so years ago, you might get a day or two reach 31-32C but most days would be 30C. Now, even the 'cool' days are 33C.

@skribe @chu if electricity goes out… you might have to rely on special phase change material vests … because sweating will not fix you if the wet bulb temp goes above human survival temp.

@SeaFury @skribe One of the things I appreciate about Melbourne weather is that when it is hot, it is not humid. Whereas Brisbane might not have gotten quite as hot, but you could never ever cool down by, say, walking into a shower fully clothed. (Yes, I have done this in Melbourne on days when it was over 40, before I got my aircon.)
