Sooner than predicted, parts of the world already too hot for humans

Global warming has already made parts of the world hotter than the human body can withstand, decades earlier than climate models expected this to happen.

Jacobabad in Pakistan and Ras al Khaimah in the United Arab Emirates have both repeatedly crossed a deadly threshold for one or two hours at a time, an analysis of weather station data found.

Wet bulb temperature (TW) is a measure of heat and humidity, taken from a thermometer covered in a water-soaked cloth. Beyond a threshold of 35°C TW the body is unable to cool itself by sweating, but lower levels can still be deadly, as was seen in the 2003 European heatwave that killed thousands without passing 28°C TW.

A US-UK team analysed weather station data across the world, and found that the frequency of wet bulb temperatures exceeding temperatures between 27°C TW and 35°C TW had all doubled since 1979. Though 35°C TW is thought of as a key threshold, harm and even death is possible at lower temperatures, so the team included these in their analysis.

Fat cats in their kool-aid kastles and kars ain’t going to be worrying about themselves. Not likely to worry about the rest of us. Question remains the usual: can we, will we, build a movement that threatens political gigs more than the dollar$ that keep politicians in office?

    “Los Angeles County recorded its highest-ever temperature Sunday as the weekend heat fanned wildfires across California and put additional strain on the state’s power network.” https://www.cnn.com/2020/09/06/weather/california-record-temperature/index.html
    121° high temperature at Woodland Hills official site (Pierce College) was also the highest official temperature ever recorded in L.A. County as well as Ventura, Santa Barbara and San Luis Obispo Counties.
