Wet Bulb Temperature. Life or death?

Unfortunately it doesn't even matter if people can stop working. If my understanding is correct 35 degree wet-bulb is basically fatal even at rest, and much lower wet bulb temperatures are fatal if one is doing working labor or in the sun. Massive and lethal weather events are going to become a reality. Since an underground or earth-covered structure stays close to a constant temperature roughly equal to the average annual temperature in a location, I'd suggest wealthy nations pay for locally-produced, earth covered heat shelters. I've half-joked that Trump's wall was really because they know the tropics will become uninhabitable and this time they don't need to build ovens if they can keep pumping out CO2 and keep the people they don't like close to the equator.

WET BULB TEMPERATURE, explained very well, thank you. I have encountered many disbelievers when confronted with 35deg C as a lethal temperature because "wet bulb" is not understood. The common response from "deniers" goes like this, " this is complete rubbish because human beings have lived and worked in parts of the world with much higher temperatures forever". This is a failure to understand both physics and physiology.

[@IKARIANOFFICIAL]

@Peter A - I'm asking this question in all sincerity here because I'm a bit ignorant on this subject. Having lived in Florida, I always noticed that it's very easy to sweat when it is hot and humid outside. Whereas when I was in Las Vegas where it was extremely hot and dry, I didn't sweat at all and felt like I was in a hot dry oven being cooked to death. So I was assuming that a hot dry place would be more dangerous than a hot humid place. So clearly I'm missing something here?

[@gregholloway2656]

@@IKARIANOFFICIAL in Florida, the sweat you were producing was not evaporating because the air already had nearly all the moisture it could hold. In Vegas, the same sweat evaporated immediately, cooling you off, and making you think you were not sweating.

[@Jay...777]

@@IKARIANOFFICIAL Let me start by saying I haven't lived in Las Vegas or Florida. However, as a general rule the human body cools itself by evaporation of sweat aka water from the its surface. A dog does something similar when it sticks it tongue out of an open mouth and pants rapidly. When humidity is very high the efficiency of this effect gets less and less as the humidity rises. At100% humidity it fails completely. At that point you are as hot as your environment. Internal body temp at rest is 37C so when the environment is at 37C you cannot exert any movement as this would generate extra energy that pushes your internal temp above 37C and you soon die, unable to cool yourself. In practice this effect starts well before 37C but don't forget it does require high humidity too. So at 35C 100% humidity your soon dead.

[@Jay...777]

@@IKARIANOFFICIAL I can only imagine that Los Vegas is very dry with little to no humidity so any sweat evaporates immediately. Whereas Florida is by the sea so humidity levels would be much higher, so sweat would linger on the skin for longer.

[@IKARIANOFFICIAL]

@@gregholloway2656 & Peter A - Thank you both for helping clear this up for me. Edit, some sites say that having sweat stay on the skin for longer helps to cool the body more than if it evaporates fast or if you dry your excess sweat off too fast. So now I'm wondering if tests have been done that show relative internal body temperatures between hot/dry climates and hot/humid climates?

For anyone doubting the seriousness of the wet bulb thermometer readings, I've spent the last 15yrs involved in underground hard rock mining in Australia. The defined safe cut-off point for workers underground is 32°C wet bulb, after which a system of safe work must be put in place to continue in the area like rotation of workers, or primarily, improving ventilation in the area. I can tell you from personal experience, 33 wet bulb is not fun to work in!

[@clivemitchell3229]

It's perhaps important to realise that people don't start dropping dead at 35°C WBT. That's when they finish dropping dead. They start quite a bit earlier. 34°C WBT kills quite a lot too. I was in Pefkos in 2003 - daytime temperature in the shade was 49°C but it was survivable because it wasn't humid. In the UK we often get humidity in the 90s but not with high temperatures. The combination kills.

[@Microtherion]

You're right. A few years ago, I'd recently heard about the whole 'wet bulb' factor in respiratory failure, and for a couple of weeks I started paying some attention to humidity - not with any great worries about it, just realising for the first time that it could really matter much at all. I was slightly shocked to repeatedly see measurements of well over 75, and often nearly 100 per cent. And we see those during fairly warm spells too. Actually, I'd be interested to know where it gets potentially dangerous: it can't be 'totally fine' at high temperatures plus 99 per cent humidity, but deadly at the same plus 100. So maybe 75 plus 40 degrees or so gets problematic? I've never heard an estimate about that...

The effect of humidity is really underappreciated. I used to live in Oman within 20 meters of the sea where the daytime breeze came from the sea and night-time in the opposite direction. In the summer the daytime relative humidity was over 90% at a stable temperature of around 41C. During the night at about 02:00 the wind direction changed and the humidity crashed to about 35%. The sea temperature exceeded 35C. It was impossible to do any outside work in the daytime as you just dripped but couldn't cool.

Great video. It affects some regions outside the tropics as well. The entire coastline of the Persian Gulf is a high risk area. The Persian Gulf has very warm sea surface temperatures (highest in the world I believe) and thus releases a lot of moisture onto the surrounding coastal areas. There this moisture meets the hot desert air which causes a dangerous mixture of humid heat. Furthermore the coastlines of Pakistan, India and southern China are risk areas outside the tropics as well.

[@MrJohnd1951]

Hi, I admire your talent for such lucid explanations. This time for me it is a recall of the past, as i worked in a met office for 32 years. before computerised sensors, we usese to measure the wet bulb and dry bulb temperatures from which we derived the relative humidity and the dewpoint temperature. The definition of wet bulb temperature (Twet) is "the temperature to which a parcel of air can be cooled by evaporating water into it". This is because as you explained that evaporation uses latent heat from the air and thus lowers its dry bulb temperature (Tdry). In practice we end up with 3 temperatures Tdry, Tdew and Twet. When the air is unsaturated, Tdry>Tdew>Twet. When the air is saturated all three temperatures become equal and humidity is 100% which usually is the case in fog. Unfortunately with the coming of computerised sensors, the use and feeling for Twet has been lost, also because in aviation only Tdry and Tdew are used. Twet is used in academic research as an airmass traces because it is more conservative. I wish to read that research paper because it becomes more serious if the threshold of fatally dangerous temperature falls below the normally reported temperature Tdry. One thing I disagree with is that I do not think that airconditioners will solve the problem in the long run. All they do is they add heat to the environmental air directly by conversion of electrical energy and all they do is advance the little time we have to make amends. Thanks for your good work. John Darmanin

[@ranty_fugue]

This problem is not limited to the tropical zone... Several years ago, I read about how the wet bulb temperature in Bandahr Mashrahr in Iran came very close to 35 degrees Celsius (it was something like 34.6). I further recall reading that various parts of the Middle East were considered to be highly at risk now, not at some point in the future. Truly a terrifying position to be in.

[@PeacemanBZ]

That's true. Within the Middle East the entire coastline of the Persian Gulf is the highest risk area. The Persian Gulf has very high sea surface temperatures (highest in the world I believe) and thus releases a lot of moisture onto the surrounding coastal areas. There this moisture meets the hot desert air which causes a dangerous mixture of humid heat.

@JustHaveaThink - I like the way you think and express thought to your viewers. At 9.20 you mention WGBT, immediately you mentioned the dynamic environmental stresses on humans, but did not mention the plethora of species. Many potentially affected species we depend on, so as I am guessing you are aware, the stresses you mentioned are felt by more than for some people at work alludes to much more risk then what was understandably stated. Agitation for a harmonious homeostasis can create a short lived peaks and troughs or another base altogether...

Just have a thing is a very depressing Channel, but its the kind of data we need to convince our self-centered selfish money grabbing politicians, industrialists and us to take action. ( Sorry I guess I'm preaching to the choir)

[@RussCR5187]

Unfortunately, I don't think the "self-centered selfish money grabbing politicians, industrialists and us" tend to make decisions based on information and data. If they did, the climate crisis would have seriously addressed decades ago. We've had more and more data, yet no hesitation in the rise of atmospheric CO2. People of all stripes tend to make decisions based more on emotion. To get the attention of the ruling elites we need to hit them where they live: in the pocket book. I particular, we need to make them afraid. Afraid of losing all their wealth and privilege. We need sustained mass demonstrations of non-violent civil disobedience. It's our only chance at this point.

nice to read others that share our view though as the pace of progress seems quite a bit too slow.

"...the psychopath is a mutation akin to a human shaped spiritual tapeworm, which is wreaking havoc among the lives of billions of people on this planet and a disease more deadly than any pandemic, a predator more dangerous than the most insatiable carnivore, and a cultivator of human misery more wrathful and sadistic than any monotheistic god - imaginary or otherwise."

In these models, were they looking at local temperature changes, or were they modelling local effects of a change in global average temperatures? There's a big difference when you're talking about equatorial regions, where there will be very little change in temperatures, as the poles are expected to absorb most of the delta-T.

4:00 - june 2024: 1000 people die in 51.8C heat in Mecca (latitude: 21.4N). Virtually zero humidity required for 50C+ to have a lethal temperature.

[@NimbleBard48]

Yeah, I randomly stumbled upon this older video and went down to comments to see if someone mentioned this. And that is the Middle-east. We still didn't get the aggregated number for the recent heatwave in India - which is still ongoing. So far we've seen separate news about over a hundred deaths since March to May and then some news in May, June about hundreds more. I bet we will get the numbers later this year when some article sums it all up. In 2015 indian-pakistani heatwave we had over 2k dead and this heatwave seems so be slightly worse...

[@Kevin_Street]

Thank you for this video, and thank you for breaking down the information in such an easy to understand way. It's really sobering. This is the future we're headed for, right now. A future where heat waves regularly kill millions of people, at least several times a year. And there's the effect of living for so long in heat that's right at the edge of human survivability, and what that does to individuals and societies. Then there's the urban heat island effect, which could make average temperatures higher in the cities than the countryside, and on and on.

@@donutemptycircle8717 I'm a competition paragliding pilot - wet bulb is a huge indicator of the strength of our thermals. Think about it. More water in the air == more energy in the air. Water after all is just hydrogen + oxygen. You know, the stuff they put the Space Suttle into orbit with 🙂😜

Wet bulb temperature. Great information thanks. I encourage everyone I know to carry an oral thermometer so they can diagnose heatstroke and hypothermia. I knew temperatures above 100 were deadly when not respected but did not know the precise 95 degree wet bulb temperature number. Thanks.

[@andrzejkawa5491]

[@piotrd.4850]

@Just Have Think - around 1:20 - yes, climate is not weather. NO - computers don't change a thing. Computational complexity for most problems (like protein folding) is non-polynomial and however much hardware you throw at the problem, you are NOT making noticeable dent. Also - 7% of more water - remember ,that water vapour is potent greenhouse gas and water itself has about 800x heat capacity. Funny thing is, that we are not exactly SURE of mechanism of heat death but on the other hand ,we have enough experience in casual disposal EXTREMELY efficient humidity absorption materials. As for 'air conditioned building' - well, you know, just 1.5m below ground you have steady temperature equal to about AVERAGE one on given latitude.

[@xxwookey]

How on earth do put out 1.5 of these videos every week, Dave?

[@TheSpecio]

Yes, who actually finances this? Production costs a lot of money and you can hardly do it alone, even on a full-time basis.

[@xxwookey]

@@TheSpecio I think Dave financed it himself for the first year and a half or so, then more recently got a patreon. It's almost all time, rather than money, given that you have the skills and software (and a computer and camera/mic obviously). I'm guessing he doesn't watch much TV and much of his free time goes on this. Dave's set of skills is very impressive: research, reasonableness, script, delivery, video editing and effects. I'd like to know what software he uses for the 'animated page throwdown with shadows' type stuff which is what makes his videos so classy. Maybe he has acquired some assistance (or more time/less job) given the extra 'another think' videos, which otherwise just seems like making life difficult for yourself.

[@JustHaveaThink]

Hi xxwookey. Your synopsis is about right (much better than silly old Grindup Baker ) :-). I use Adobe for all the editing and animation (Photoshop, Acrobat, After Effects and Premiere Pro.) The animated fly-ins are done in After Effects, which has a limited 3D facility. Thanks for your feedback. Much appreciated.

[@JustHaveaThink]

Hi TheSpecio. I'm supported 100% by the kind people on my Patreon page. That's all. I do all the work myself so there's no-one else to pay.
