Despite all the body's thermal efficiencies, these areas could soon be uninhabitable, according to Loughborough University climate scientist Dr Tom Matthews in The Conversation.
When air temperature exceeds 35C, the body relies on sweating to keep core temperatures at a safe level. However, when the “wet bulb” temperature – which reflects the ability of moisture to evaporate – reaches 35C, this system no longer works.
“The wet bulb temperature includes the cooling effect of water evaporating from the thermometer, and so is normally much lower than the normal (“dry bulb”) temperature reported in weather forecasts,” Dr Matthews wrote.
“Once this wet bulb temperature threshold is crossed, the air is so full of water vapour that sweat no longer evaporates,” he said.
This means the human body cannot cool itself enough to survive more than a few hours.
“Without the means to dissipate heat, our core temperature rises, irrespective of how much water we drink, how much shade we seek, or how much rest we take,” he explained.
Some areas – which are among the most densely populated on Earth – could pass this threshold by the end of the century, according to Dr Matthews.

He must not have A/C.

Phu*cking chi coms. They emit twice the CO2 than we do.

It’s been a unusually cool this summer where I’ve been

Given that temperature, climate and the body’s ability to dissipate heat explain, in part, the rise of our species, why shouldn’t these things explain our extinction?

All species go exstinct, eventually. If you can't handle the ups and downs of a climate changing by 1 degree C, you should probably find a creek to gurgle in.HHusky said:Given that temperature, climate and the body’s ability to dissipate heat explain, in part, the rise of our species, why shouldn’t these things explain our extinction?

That’s a result of climate change as wellMikeDamone said:It’s been a unusually cool this summer where I’ve been

Live in a northeast city before AC and wear a wool suit to work in August and then pop off
