For the first time, humans were exposed to a deadly combination of heat and humidity. Here's how long they lasted - ABC News

Reply in thread

The article is about an experiment, where people are exposed to 35°C wet bulb temperatures, but in different settings. Sometimes lower temperatures but higher humidity, sometimes vise versa, but always 35°C wet bulb temperature.

So far the assumption was, that humans can't survive a 35°C wet bulb temperature for longer than 6 hours. And at current warming this is unlikely to be naturally the case within this century.

However the experiment gives hints to believe that humans can't survive at lower wet bulb temperatures either. It looks like with lower temperatures and higher humidity, humans can get very close to that 35°C wet bulb temperature, however people seem to struggle more with higher temperatures and lower humidity.

A possible explanation could be, that while more sweat evaporates in lower humidity, the body has a limit for how much sweat it can produce. And if you keep raising the temperature, that the human body simply can't produce enough sweat to cool itself.

That's pretty much what I took away from the article. They mentioned they experiment with several people, however the article was mainly about on person in the experiment, a 30ish year old, athletic male.

Edit: add some graphs from the article. Sorry for low quality, but as you said, the layout is quite atrocious and on my phone it keeps jumping around on it's own, so I lost patience.

I thought it was because proper farming.

Like being able to support larger groups of people, where individuals could specialize in other things than hunting, gathering and whatever else was keeping the early humans busy.

On the other hand I've heard we've been possibly farming long before 10,000 BCE.

Sid Meier was apparently baffled by the decision to launch Civilization 5 without Genghis Khan: 'Sid said, What?'

The second big change is that when you transition from one age to the next—there are three ages, Antiquity, Exploration, and Modern—you'll pick a new civilization to lead, one that was at the height of its power during the age in question. So you might go from controlling Rome in Antiquity to Mongolia during the Exploration age.

Well, I still play civ4 bts, never went beyond civ5 and unless I update my hardware probably won't try civ6 and civ7 anytime soon.

But what you mean, you'll change civilization midgame? I can't wrap my head around this concept. Or does your civilization simply change it's name?

Ex-Porn Shop Staff Say Mark Robinson [Republican candidate for governor of North Carolina] Was A Regular. He Denies It.

Sorry, I am not from the US. So this guy consumed porn. And what? Relax people!

Might sound weird to prude people, but most politicians had sex before! Some may have kinks! Why do people care about other people's sex life, if they aren't attracted to them?

And what has this to do with a community called politics? I don't get it.

Edit: wow, many replies! Thank you all for educating. If this man is saying people shouldn't consume porn, then yes, you are all right and it's a controversy that makes sense to shine some light on. I didn't think about that.

I actually watched that episode last night, so that post was kinda jumping at me. What are the odds...

Sagan, a real teacher. Not only smart, there are quite a few smart people. But also able to make something complicated easily understood. To make something abstract sound straight. To make something minds can't grasp comprehensible. A beautiful ability!

It would not, though. I assume your glasses to have a larger surface than your eyes. Additionally, eyelash do are real good job in filtering the air in front of your eye.

‘Megayachts’ are environmentally indefensible. The world must ban them.

And when they're moving, they're highly inefficient as well. With a displacement ship hull designed to part the water their top speed is limited by their own length. A ship cannot overtake its own bow wake and with a length of let's say 70 meters you end up at a top speed of about 20 knots. Which isn't slow, but also not that much faster than cargo or passenger transport (maybe going 10 to 15 knots).

While a cargo ship is mostly longer and could theoretically sail faster, it is designed to be economical. It gets an engine that is most efficient at a certain speed, for example 12 knots at ahead standard, the propeller is cut for efficiency etc.

A yacht is designed to be comfortable and fast. It gets powerful engines that combust however much they need to combust. The propeller may be designed to produce less noise or vibration instead of being most fuel efficient.
