@0101010001110100 Thanks for the warning! FYI, wet bulb *globe* temperatures (which this map reports) aren't the same thing as wet bulb temperatures.

When you hear about certain wet bulb temperatures being unsurvivable, the assumption is one has already found shade and that is the wet bulb temperature out of direct sunlight. Or put another way, those fatality limits are if the wet bulb temperature in shade is over a threshold, then it's fatal.

Wet-bulb *globe* temperatures are slightly different: they're the weather forecast in direct sunlight. Moving to shade helps get you into a lower wet-bulb temperature.

So this is Bad, but it's not *quite* as catastrophic as it sounds like.

"Findings

The final dataset included more than 11.5 million tested isolates. Raw antibiotic-resistance data included nine pathogens and 43 types of antibiotic agents. Significant correlations between PM2.5 and antibiotic resistance were consistent globally in most antibiotic-resistant bacteria (R^2=0.42–0.76, p<0.0001), and correlations have strengthened over time. Antibiotic resistance derived from PM2.5 caused an estimated 0.48 (95% CI 0.34–0.60) million premature deaths and 18.2 (13.4–23.0) million years of life lost in 2018 worldwide, corresponding to an annual welfare loss of US$395 (290–500) billion due to premature deaths."

 

Air pollution (PM2.5) can be a direct vector of antibiotic resistant bacteria, and caused approx 0.5M deaths in 2018, per new study.

Just published in The Lancet Planetary Health (peer-reviewed scientific journal):
"Association between particulate matter (PM)2·5 air pollution and clinical antibiotic resistance: a global analysis" (by Zhenchao Zhou, PhD, Xinyi Shuai, BSc, et al.)
https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(23)00135-3/fulltext

"The major air pollutant, in the form of particulate matter (PM)2.5, has been shown to contain diverse antibiotic-resistant bacteria and antibiotic-resistance genes, which are transferred between environments and directly inhaled by humans, causing respiratory-tract injury and infection. [7, 8, 9] PM2.5 could also increase cell-membrane permeability to enhance the efficiency of horizontal gene transfer, accelerating the evolution and exchange of antibiotic-resistance elements in bacterial pathogens. [10, 11]"

@ComradePorkRoll
In 2000, I went to Burning Man, which is, if you don't know, a festival that is held on the dry lake bed in a desert, at the end of summer, at which there is no general provision of water. You are warned when you buy your ticket that your hydration is your problem, and that the average human adult in that environment requires two gallons of potable water a day not to die, so you'd better figure out how long you're going to be there and bring enough water for yourself.

I'd never been camping before under such circumstances, but the person I was attending with had a great bit of advice that worked well for me. He insisted that I get a Camelback, which is a water backpack with a drinking tube.

I made a point of never leaving my tent, not even for a trip to the loo, without having my Camelback on my back. The pragmatic upshot was that drinking water was always as near as my right shoulder. Sipping from the tube became habitual.

I've never been so hydrated in my life.

First credible flood warnings in my area.

Some context: The region in which I live, after catastrophic flooding in the middle of the 20th century, domesticated and tamed all of the rivers. We have a system of dams and other flood control that mostly keeps our water levels very stable. New Englanders do not understand how artificial the stability of our water levels is, and the kinds of floods we used to have here before all the dams were built to make sure that never happens again.

But now we're getting rainfall like never before, and it's not like our dams are any better maintained than our bridges are - and our bridges are a known scandal.
