Over the hundreds of thousands of years of our existence on the planet, modern humans have managed to adapt to a huge range of climates—from the arid heat of the Sahara Desert to the icy chill of the Arctic. But we have our limits. If temperatures and humidity rise high enough, even a robustly healthy person sitting still in the shade with access to water will succumb to the heat.
High temperatures prompt the human body to produce sweat, which cools the skin as it evaporates. But when sky-high humidity is also involved, evaporation slows down and eventually stops. That point comes when the so-called the wet-bulb temperature—a measure that combines air temperature and humidity—reaches 35 degrees Celsius .
Raymond and his co-authors examined temperature data from more than 7,000 weather stations around the world going back to 1979. They found that extreme humid heat occurs twice as often now as it did four decades ago and that the severity of this heat is increasing. Many places have hit wet-bulb temperatures of 31 degrees C and higher. And several have recorded readings above the crucial 35-degree-C mark.
Given the paucity of weather stations in some of the involved places, such as parts of Pakistan, “there’s probably even higher [wet-bulb] values out there,” says Raymond, who now works at NASA’s Jet Propulsion Laboratory. The highest extremes were typically only reached for an hour or two, so they do not yet necessarily hit the limit of human tolerance. But such events will start to last longer and cover larger areas in a warmer future.
So they can move. Like humanity always has. Next
Weather manipulation..they're going to kill us one way or another
Yeah… and then it’ll be a number of minutes of exposure. The ever diminishing spiral of “Boy, we sure f’d ourselves on this one!” “I think we really should’ve … cough… cough… puke… have heat stroke .., expire…!” Children… “uh, what we’re you saying?”
the 7 billions of ppl on this planet farting too much
Mexicano, anyone?
HabitatFHGB Habitat Loss for Humanity
We need to quit using fossil fuels. If it can kill us its probably terrible for the environment
'Why are we here. Just to suffer'
From 2006:
Umm...
'Research has suggested' a lot of things
Meanwhile ClimateCult has been trending and conservatives are crying about the Global Warming 'Propaganda Machine' 🙄🙄🙄🙄🙄
Again? Do you realize that you're lying? Again.
BS !
The real war is coming. No army, tank, ICBM will be able to attack the hurricanes, sweltering heat, tornados, rising sea levels, forest fires, droughts, etc. We're in deep trouble and it scares the HELL out of me that there are tons of people who think global warming is fake.
And if we wait until the coming decades…
You endorsed joe biden who broke records selling oil! Thanks for that!
Good.
Reforest the Texas coastline to forty miles inland.
Yes, but think of the shareholder value that was created! ♥️
