As climate change continues warming the planet, a new and invisible killer is emerging: extreme wet bulb temperatures. This refers to a potentially lethal combination of heat and humidity that, until now, have appeared somewhat infrequently around the world. But models predict that they are likely to become an increasingly big problem in the coming years.
In this episode we explore the intersection between climate science and meteorology to tell you where in the world is most at risk of these increasingly dangerous conditions.
Weathered is a show hosted by weather expert Maiya May and produced by Balance Media that helps explain the most common natural disasters, what causes them, how they’re changing, and what we can do to prepare.

As a construction worker in Florida I would go to jail and be called inhumane if I brought my dog with me in same hot environment that we are expected to work in day after day.
Physical labourers and farmers that have to work from dawn to dusk, day in day out (7 days a week), year in year out, in these hot and humid conditions?? Yet they are among the most beneficial to society?? If they stopped working because of the weather, we'll suffer. If they continue working, they'll suffer, probably die, and in certain areas replacements are hard to come by.
I had heat stroke twice last summer. Turns out lack of salt can also cause dehydration 😅 i was drinking water like a fiend but no electrolytes
Good point
I don't know how you work in those heat conditions
I have been doing construction for 25 years and that is why I will no longer do construction
I remember hearing about when the Crystal Cave in Mexico was discovered. It was found 2000ft underground by a mining operation. When it was found, the ambient temperature was 118degF and the place was filled with groundwater. The miners pumped out the groundwater from the cave to explore it. However, being underground surrounded by water, the relative humidity in the cave was 100%. This being at 118degF meant the wet bulb temperature was 118degF. Everyone who entered the cave had to wear a full-body air conditioned suit not only because it was hot and humid enough that the body could not cool effectively, but because the wet bulb temperature was so high above the average human body temperature, anyone who tried to breathe that air without the suit would have water condense in their lungs. It was so humid in that cave you could've legit drowned breathing the air in it!
When I saw this my first thought was that the moisture in the lungs was most dangerous not the heat .
Thanks for that insight. I never knew this. I did enter a deep cave that had a lot of heat and moisture- going deep down, but did not know how bad it can get. It's incredible how well-balance the earth is, but humans are throwing it out of balance the moment they say, "There is no God"-- they do whatever they want.
🟥♨️🟥 The cave now is permanently sealed off.
@@marsflee3815dont generalize things, there are a lot of atheist do care a lot about nature, and there are also doomsayer that also religious and doing nothing, either you belive in god or no, some people take this things seriously unrelated to their believe
Is this why I'm finding it harder to breathe in the summer because of my asthma but it seems every year it's getting worse and in tine months i used to be ok I'm not now
I survived a heat stroke and what people don't realize is it's not over just because your body cools. Stay out of those extremes is far more important than just coming back down from that heat.
High internal temperatures cause real damage to organs and can cause your body to not cool effectively in the future. I suffer in 75+ F temps now compared to as a kid playing very hard in 95+ F. I lost my ability to cool so much that I have to finish my showers with cold water for 1-2 minutes and then still sit in front of a fan for another 10-20 minutes just to cool back down. That's with taking showers that feel barely warm to the touch. My warm showers are cold to other people.
Thank you for this. I had an asthma attack for the first time due to being in 90 temps for a few hours. It felt like my whole respiratory system was inflamed. I’ve been in cool temps the past few days but the asthma problems linger. Thanks for the explainer.
Heat stroke is highly terrifying because the organ damage it caused is permanent. And once body temperature rises beyond 43°C, positive feedback loop will kick in, constantly heating the body in a vicious cycle until you died.
I did not know that about heatstroke, thank you for sharing this!
Cold showers close your blood vessels and make you conserve heat. You need to open the blood vessels as much as you can with a warm shower not cold to cool down. Things that help blood vessels to be more flexible like vitmin e vimtin c vitimin k and ceyenne pepper helps blood vessels to open up. Letting heat escape better from the body. Cold showers are great for if youre cold all the time as they constict the blood vessels and send heat back into the core.
Believe it or not the air conditioner that everyone has grown accustomed too is the danger not the heat.
And the vast majority of people say they love the hot weather, for the longest time growing up, I’ve never understood why
@@Helieos45bullshit
let human wave russia because it goddamn hot downhere
I work outside about half the year and my industry is incredibly resistant to changing the way we work. I've been to the emergency room more than once because of it, and last year someone died. The OSHA fine was barely a slap on the wrist.
Thank the right-wingers around the world for their continued weakening of the ability of agencies like OSHA and the CDC to enforce and uphold regulations.
@@jaykanta4326 every time my mom cries about how close I came to dying that one time or the other time or the third time or the forth time or the times I don't go to the emergency room because I can't afford it and workers compensation always wants to fight I tell her not to vote for people who make it possible for my company to kill me, but she gets mad.
I'm so sorry you're being subjected to this 😑
Those of you complaining about the Right Wing need to realize many of them are controlled opposition.
The Dems are of zero improvement because they promiie with big, placate with little things, then make laws and regs that make leadership in government and conglomerates very rich.
Suggest you try watching Russell Brand. We need to meet in the middle to fight the powe.
Avoid getting caught up in the illusion that what happens is 'one party's fault.'
How about more rail instead of tax rebates for EVs that only the rich can afford? We need equity, durability, and systemic change.
We certainly could use a lot more restoration agriculture and rainwater harvesting education, for one.
Common sense says you quit a job that kills people and won't change.
UPS won't put AC in the delivery trucks. The class action against them is going to be huge.
I see a lot of comments saying things like "I did this or that in hot temps and it didn't bother me" but they seem to have missed the entire point of the video somehow. It's not just the temperature, it's the temperature plus the humidity in the air. If the air is hot and dry then you can sweat through it and be fine, just drink lots of water. If it's hot and wet tho, then you're up the creek sans paddle because your sweat will not evaporate at a meaningful rate. AC and a dehumidifier will help, but they aren't always available, especially if you're working outside.
I live in a part of BC that gets very hot in the summer, over 40 degrees some days but it's usually quite dry so it's been manageable. Over recent years tho it's been getting noticeably more humid and I've definitely been feeling the difference. Things are gonna get rough folks, and I think it will happen much sooner than most estimates since many of them assume we'll make some real changes to prevent the worst, while I assume we won't.
Thanks for commenting. I was about to say the same. The video's entire point is that humans have a point - apparently about 31 C wetbulb - where sweat doesn't evaporate enough to cool us any more. *_At that point we cook!_*
@@LabGecko I'm going to try what she did in the video later this summer, the bit where she's got a thermometer wrapped in a wet cloth and she's twirling it around in her bathroom.
I'm curious to try that on my deck once it gets hot around here, which should be anytime now altho the Spring has actually been pretty chilly so far and I'm still wearing a sweater most days, plus a coat in the evenings.
Be interesting to see what sort of numbers we get here in the Summer tho using that method compared to a regular dry thermometer.
Not only are we not making the necessary changes, we're inventing new ways to justify capitalism making things actively worse, "because carbon capture eventually" or whatever other dumb shit the corporations have been propagandizing about. I mean, when you are relying on solutions to climate change being touted and invested in by Bill Gates, it is both absolutely safe and frankly necessary to remind yourself that you aren't even taking climate change seriously at all anymore, you've just decided to sidestep into a fantasy la la land.
@@MrRemnants Interesting that you've had a chilly spring as well. We've had one here in Finland as well. We actually had days last week when it suddenly just dropped below zero (celcius) and even snowed for a bit 😂
I doubt our weather phenomena are related but it's a good reminder that climate change isn't just about rising temperatures but about weather getting all kinds of fucked up.
@@LabGecko It's actually worse than that. You don't even have time to really start cooking, your vital organs just shut down and you die. Very unceremoniously.
After that the cooking is interrupted by all kinds of cool microbes that eat you up 😁
I’m traveling since 3 months through SE Asia, and even though I’m from a tropical country I can’t understand how people manage this amount of heat/humidity in their everyday life. I started to have headaches, dizziness (feeling like tripping) joint problems like never before… Water is not enough… Massive respect for the people who live in these areas
During a period of six months, I had the opportunity to engage in employment in Haikou, China. I recall experiencing emotional distress upon exiting the shower due to my inability to achieve a state of thermal equilibrium. No air, no windows that opened. I experienced a weight loss of thirty eight pounds (135 lbs to 97 lbs) over a period of six months, and afterwards returned home as a result of enduring serious ailments that necessitated a three-year recovery process. Upon returning to my residence, I observed a notable disparity in my vocal timbre compared to the one I possessed before to departure. Remarkably, my voice had acquired a quality reminiscent to an individual who had engaged in habitual smoking for a duration of twenty-five years, despite the fact that only six months had transpired.
@@mimishandleyou coulda said that without pulling out the thesaurus
LOL, I totally agree.@@boenarrow

And everyday i am still debating people whether climate change is real or not..
we are doomed.. i don't see any other outcome, we start to change when it's too late. While some of us have been shouting the same thing for the last 50 years.
It's over, i don't see it anymore.
Lol
I am writing this as of May 2024 and Southeast Asia where I live is currently suffering an abnormal heat wave. It's been getting worse and worse within my lifetime and I am 52 years old. 35 C is the COOLER temp now and it's reaching 38 to 45 C at its hottest, WITH 60%+ humidity. It's not funny when yet another citizen from the global North / First World insists to ME that climate change is fake. Like, what am I and millions of my fellow Filipinos and Southeast Asians here... just figments of someone's imagination?
If it happens once, the likelihood of it happening again is exponential. Please never underestimate these hot conditions. The decline is sudden and feels horrible. I survived this only because I knew how to stop it by laying in a bed of ice that i spilled out of a cooler in a barely-coherent state. Don’t be me.
Where?
To clarify, once a person has experienced high levels of heat exposure we tend to me more susceptible to future levels of heat stress. Same for cold exposure. Don't take my word for it though - I learned it in the US Army Spec Ops survival course.
Hopefully this comment stays high up, because it is 100% accurate. I've suffered heat exhaustion a few times now, and I better know my limits now, but it is scary how fast it can creep up on you. This is not something you can "push through" - you have to actively cool down if you can.
@@LabGecko I AM going to take your word for it. What are you suggesting, that I go out and experience it for myself? I don't want to.
the crazy part is that what Kim Stanley Robinson predicted would happen in 2025 in Ministry for the Future, a deadly wet bulb event in India, already happened last year
The past two weeks here in Northeast Thailand, along the Mekong River, have been unbearable. Temps between 40 and 45 daily and high humidity. Very little wind except for an hour or two before dusk. I've lived here 18 years and never experienced anything like this. Old folks are dropping like flies.
wow - intense -something is happening
Come on down to Malaysia for a short holiday. Our current daily temperature falls between 32 - 34°C only. No heatwaves. We have plenty of public places with air con to cool down like shopping malls, in public buses & trains and certain restaurants. Or you can travel to Cameron Highlands or Genting Highlands which are sitting high in mountains with cool temperature around 23°C if you prefer much cooler environment.
@@Dellylo304ficus Can I ask how Malaysia produces its energy? I mean, where does the air con get its energy from?
@@melodicseaweed387Well, we're a gas & petroleum exporter. Our petroleum & gas are among the cheapest in the South East Asian region. 😊
@@Dellylo304ficus So your country is contributing to the suffering in NE Thailand even though you have loads of sun and could get much of your power from solar 🤔
I have lived in South Florida on and off for 60 years of my 65. I plan to retire in 2 years and I’m out of here as fast as I can sell, I’ve taken to calling Miami ,Phoenix east with humidity. I know I’m older but the heat is getting worse I trained for Ironman triathlons down here up to 15 years ago can’t imagine doing it now. Without air conditioning this place is unliveable.
People usually retire to Florida finding it less demanding on aging body
As an ex-Phoenician who's lived there in 2 different x's, it's more humid there than ever before. The monsoon season used to be brief during the summer; now it's all summer long. It may get to Miami levels eventually.
I used to live in Europe and moved back to Singapore recently. The heat and humidity is far worse than i remember it to be and its only March. Been feeling sick with Heat Exhaustion this week.
Last year in Shanghai, China for the first time in my life I experienced the heat in a way that I just wanted to run from it. I had to work outdoors, in the sun and I couldn’t think, my brain was literally getting hot and it felt like I was a lab rat which was put into a microwave. That was scary and, again, for the first time in my life, I’m not looking forward to summer
Yeah that was probably their artificial sun
Why don't you look at historical temperatures and see that it's been just as hot in the distant past.....
The only time I experienced heat stroke was in Shanghai during summer, I threw up on the sidewalk when I was presented with a few flights of stairs to climb to my destination. I couldn’t do it, I was exhausted from just walking. It’s no joke there. Now I’m living in tokyo and the wet bulb temp is happening more and more. It’s truly scary
@@Tcat586 Yes, China has a very clear continental climate, some cities in the north get to -40° in winter and +40° in summer
temperature is not the problem. It’s the combination with humidity. And the humidity is increasing.
One of the things that I, at least, have seldom heard about in relation to your last question deals with *vernacular* architecture and building methods. Think of the way old homes were built on the island of Santorini, for example, or the thick adobe walls of old houses in the desert southwest region of the United States, or the passive "air cooling" methods used in homes through out the Arabian desert regions. Modern home construction methods, at least in the United States, are a horrible, unsustainable failure.
"Horrible, unsustainable failure" pretty much describes the whole western city layout idea, with its preponderance of asphalt and over-reliance on cars ( *another* unsustainable mess), and its dearth of trees, sidewalks, protected bikeways, and public transport options.
It all comes full circle, and we must deal with climate change in a multi-prong approach that considers *all* of the things that are contributing to the big problem.
well said
It happend arround the world. I live in Panama, in a tropical wet country and the house design have change to asume that you will have AC... that its so narrow minded!!!... cement without gardens, small windows without good air flow, no shade over the windows.... and we have El Niño.... I can believe how much blind people can be, there is not enough energy in the world to have AC in every house...
Simple vernacular does not help if it is hot AND humid, say, 42C and 95%+ humidity. The classical physics of evaporation and heat radiation forbids cooling. In areas with seasonal patterns one can go underground. in tropical areas this may not be possible.
What could help is a relatively new fabric with selective IR transmissibility, invented at the MIT. It can cool up to a difference of 10C, even in humid conditions
All about "Consumerism" and the Profit Margins.
@@monnoo8221 they also have a new house paint that actually cools the area around it because it reflects so much sunlight
Many here talk about their anecdotal experiences with climate and related changes, but the point is the entire biosphere, not just us/people and our personal observations.
I think these events occur more than we know. I didn't know this science but it's exactly what I've been trying to explain to my son for years. The physical affects of "wet bulb" happen more frequently than studied. I live in the heart of Texas, and our wet bulb conditions wobble quite a bit. I believe we've had a few "events" already this summer. When it happens, it feels like a microwave outside.
Japan has been providing small community housing compound for the elderly and poor that can't afford air conditioning.
It looks like America's homeless shelters, just beds along one wall and tables to play games along the other, but it does save lives and run less air conditioning.
If a person lives alone they encourage people to use the community housing even if they can afford air conditioning so they put less stress on the power grid just to cool one house for a single person during the hottest seasons.
A lesson that the U.S. should take heed of. Once again, the coming summer in the U.S. will claim the lives of hundreds of U.S. citizens, most of them elderly.
That's f---ing terrifying. Do you have any idea the conditions that people in actual homeless shelters experience? There's (many, many) good reasons homeless people establish tent camps instead of homeless shelters, and why the only way to actually resolve those homeless camps is by resolving homelessness itself (literally giving them individual homes) and not shelter solutions. Shelters are literally more likely to make homelessness worse, simply perpetuating the problem; one by failing to provide actual housing-first solutions, and two by providing horrible conditions where sexual assault, violence, theft, abuse, etc etc can be concentrated. If our solution to climate change becomes "treat ppl the same way we do homeless people; out of sight, out of mind" then we might as well just give up any pretense of taking climate change seriously right now and have a year long party before nuking the entire surface of the planet with every available nuke, and save ourselves and all the other lifeforms the horror of the next few centuries.
AC is not a solution. When the power goes out, which is more likely on a hot day, everyone is trapped and going to die.
@@aluisious Yep, find a better solution. Elevation, shade and breeze are quick fixes.
Japan also has the highest gdp to debt ratio. Socialism comes at longterm economic costs. The USA could manage its debts if it reduces its foreign military bases, which are also contributing to climate change and reduce its aid to other countries.
The terrifying part is that millions of people keep denying that the problem even exists. I live in Alberta and I was completely floored by some of the absolute insanity I saw online from my fellow Albertans. Even with huge swathes of the province in flames there were people claiming that the fires aren't real and it's all a hoax simply because they personally could smell any smoke. When I responded to one person with the fact that where I was in Edmonton the smoke was so thick you could see maybe a block. Of course, instantly I was attacked and accused of being a shill for Big Climate whatever the hell that is and being in on it. Of course, the Jewish space laser thing was making the rounds as well. Some of the more imaginative ones from conservatives was that our Liberal Prime Minister was behind it all sending so-called eco-terrorists out into the bush to start all the fires to push his phony climate agenda. Of course, it wouldn't be Alberta if there wasn't some good old-fashioned down-home racism thrown in with Native people were behind it all to scam money out of the government. I can't help thinking we are so screwed.
Indeed in the US and Canada this issue has unfortunately been politicized instead of leaving it a scientific topic. In Europe where I live, the main correlation between understanding man-made climate change is with education: highly educated people know man-made climate change is real and we need to act on this threat, this is less the case for poorly educated people. In US and Canada the main correlation is with politics: conservatives/right-wingers deny climate change while liberals/left-wingers accept this scientific fact. This is sad, as poltics is often linked to emotions and right wingers in the US/Canada will stubbornly deny reality because this would hurt their feelings (pride being one of them).
Deaths from hypothermia exceed those from heat stroke by more than 10 to 1. People adapt to hot weather by doubling their rate of perspiration over several weeks.
The greatest number of heat stroke deaths occur in normally cool areas during heat waves.
Unadapted people are exposed to extreme heat and the situation is compounded by heat retaining buildings and lack of air conditioning.
The Red Sea, Gulf of Aden and the Persian Gulf are notorious areas for extreme heat and humidity.
@@johngeier8692NOAA found that between 1988-2017, there were almost 5 times as many deaths attributable to heat compared to cold.
Just watched the movie "Don't Look Up." It's an amazingly accurate portrayal of modern life and humans' inability to deal with inevitable catastrophic events. People just don't care about data anymore. It's all about what you believe. I don't hold out much hope for our future. People are too stupid and they show no interest in learning anything.
There is hope. People are steadily leaving religion in the US, and i think part of it is because they are learning how to parse out false information. Don't be discouraged by those who stay stuck, remember that even just 0.1% of 100 million people is still 100 000 people posting online, so they'll seem numerous even if they are relatively few.
Btw, as a reference the US has a population of around 320 million people.
When I was in Death Valley the concern wasn't the heat, it was the arid air. Humidity as low as 0.25%.
In the summer it is actually against the law to pass someone broke down on the highway.
This was years ago before cell phones came into use, I saw a family of 4 broke down on the side of the road. This was not on the main highway and it might be hours before another car would come by. They tell you to carry 1 gallon of water for every passenger in your car in case you break down. This family had no water at all. I had 2 gallons in my pick-up and I gave both to the family. I said I was going to call for help for them and to drink the water. I said I would return with more after I got help on the way. I even gave them 4 Solo cups i had.
I called for help, picked up 5 gallons of water and headed back.
The family were all sitting in the shade drinking my water when I got back.
The tow truck driver showed up in about 15 minutes and gave them even more water. The dad laughed and said we were overly obsessed with water. Neither the tow truck driver or me were laughing. We knew that death from dehydration can happen in a few days in a normal environment, but out there it can happen in hours. And it's hard to feel it coming. You don't actually feel that thirsty. You just suddenly realize that you have died.
Good tip for cooling down fast with just a cold water bottle: hold it to one side of your neck/throat, basically.
You have both a major vein and major artery in your throat - (your personal) left side flows to the brain, the right flows to the body, and they're both very near the surface so holding a cold object to them works pretty quickly.
I recommend beginning with holding it on the left for a few minutes at first - to keep yourself conscious and thinking clearly before swapping to the right to help cool the body. Don't drink from the bottle until you're feeling more clear-headed again (the bottle usually warms faster, in my experience)!
thanks, I learned something
I suffered from heat exhaustion one summer in Orlando, Fl. I had neglected to drink enough water for the activities I was doing, legit felt like I was going to die but luckily I had someone there that noticed and got some ice packs on my femoral arteries and under my armpits, without that I'm sure I would have died.
ever since that day, my body cant handle heat the way I used to be able to. something changed that day, whether its phycological or physiological, I don't know but that experience scarred me for life.
I got heat exhaustion at age 11 in VA. It has affected me the rest of my life. It is the amount of humidity that causes me to be ill with heat. Dry heat does not bother me.
I’ve had bad overheating multiple times in Georgia (US)
I can’t take even warm temps like I used tio
Yeah I work outside in south Florida. An app on my wife's phone said temp 95°, feel like temp 117°. It was the day after 4th of July. Went home with a migraine. I had like 6 waters that had been frozen, but didn't help
I got heat stroke in Massachusetts, hauling ass on my bike from the parking lot to the Martha's Vineyard ferry @ Woods Hole, about 2 miles.
It was SO HOT! Physical exercise makes it 10x worse. Had to strip to underwear on the ferry. Lay down on the bathroom floor, poured cold water over myself, turned purple, thought I was going to die right there.
🥵🚵
@@Earthbound369 yes. I opened the refrigerator and layed on my back on the tile floor next to the fridge. It sucked the heat right out
81° celcius is a pretty good sauna temperature. Even without clothes that starts to get uncomfortable in say 30 minutes. I've been in a sauna that warm with clothes on but only for a few seconds at a time and even that is stifling. I can't imagine what it would be like to have that as outside temperature 😐 That sounds like an actual horror movie scenario.
Actually a sauna with 95°C isn't a problem as long as the air is dry.
But who on earth goes into a sauna with his clothes on???
There are recipes (pulled pork for example) that cooks meat at those temperatures.
@@hg6996 who on earth goes into a _dry_ sauna???
That was the felt temperature or heat index temperature. I guess the dry bulb temperature was around 40-50 °C? The problem as they said in the video was the high wet bulb temperature because of extreme heat and extreme umidity together.
@@hg6996 First off, we were specifically talking about wet temperatures and like Emilia asked who on earth hangs around in a dry sauna?
Also thank you for your explanation, I've only been to sauna since I was about 2 and distinctly remember the times when at 6 years old my grandfather would have us sit with our backs straight in a 100 degree sauna, very much not dry. So I know you can survive in a sauna above 81° my point was to try illustrate to people what that kind of temperature actually feels like.
As to why would someone go to a sauna while clothed? Well sometimes you need to do a check up, maybe add firewood, in a smoke sauna you need to go in after it's heated to open the shutters. You know all kinds of reasons depending on what kind of a sauna it is.
I have to ask though, what were you thinking, when you decided to mansplain saunas to a finn?
I’m from the south SF Bay Area. We hardly ever had humid hot days. Now we have them all the time during summer.
I used to love the weather in Freakmont. I had so many fruit trees.
I live in SE Texas right where one of those red spots sits on that map. Bracing my self for some of those 'wet bulb' days, Especially with the incompetent power management in Texas. (Talk'n at You Abbott).
yes, living in Austin and hoping to retire one day to a higher-elevation city in NM or AZ or NC one day. Walked the dog for 5 minutes at 2pm and couldn't wait to get back inside.
It's really good someone is covering the dangers of heat exposure. Seems like nearly everyone warns of the dangers of cold weather while praising hot weather associating it with fun summers and whatnot.
This winter was the warmest on record in Europe and all people could say was "such nice warm days, we can hangout in the park!"
@George Pilzer I grew up near the gulf coast in the US and it could get very hot and humid. I would see dew in the morning. I always took heat more seriously until I moved to the Midwest
I agree. For decades now, listening to all the weather forecasters all say the same words: "The forecast is for another beautiful day of hot weather!"
The words "heat/hot" & "beautiful" don't go together. Never did!
@Tcat586Haven't you ever heard of "heat stroke"??
Summers always meant endless swarms of mosquitoes to me. Didn't matter where, I'm a mosquito magnet. Cold weather suits me just fine
Also, we have got to the point where a car doubles as a cooking oven
Central Florida. It gets into the nineties here and the only reason we don't have one hundred percent humidity is because the mosquitos occupy the volume that water molecules would otherwise occupy.
😅
I'm in South Carolina. Definitely understand that 😅
As long as I can recall, I lived in southern CA. Hot but dry summers.
Why do all weather forecasters always put "hot" & "beautiful" together when virtually everybody during the summer is living in A/C homes & businesses & saying they couldn't live without it??
I moved from Melbourne to Reno. I traded low, hot, and humid for high, cool, and dry. Reno is 600 miles from Las Vegas. We do not depend on Lake Mead. Reno is west of Los Angeles!
People think of Reno as ‘sin city’ and a gambling town. Reno is primarily the gateway to California. This place is a warehouse for goods entering and exiting California.
We get some high temperatures on summer days, but only for a few hours. Temperatures cool off quickly at sundown.
Smoke from forest fires in the Sierra is nasty. People don’t know yet, but the fires will be worse in the East.
The wet bulb in east texas has been bouncing around mid to low 90s at peak parts of the day last couple of weeks. Seriously considering moving to a different state. It's so hot that the wind blast from riding a motorcycle feels more uncomfortable with more speed. Insanity.
To my fellow Veterans that had the displeasure of serving in Dhahran, Saudi Arabia... Khobar Towers (1996 destroyed by a terrorist attack killing 19 and wounding 498) I can honestly say it is the hottest place on the planet!
In the 60's student pilots like me learned to swing a wet bulb thermometer and subtract that reading from the dry bulb. Dividing the result by four gave the height of clouds in thousands of feet. It was all the weather information available to us.
Is that height above terrain or above sea level?
@@Fomites height above where the wet bulb temp was measured.
and how about weather modification, geoengineering, and HAARP? All the pilots, military, and meteorologists that did not speak out WILL face judgement!
@@duediligencedrag You gotta say it on the 6 o'clock news, or else nobody hears it.
@@paulsawczyc5019 Thank you for saying this. When I run for president I'll make sure to be on national 6 o'clock news stations :)
For the first time, I hung a shade over the hottest side of my house. It really kept the sun off and cooled the home. My electric bill was lowered. If more people did this we could use less electricity.
We built a patio-covering which REALLY helped thermo-regulation.
What fascinates me is it turns out that using a very white material, and calcium carbonate, yep, seashells, works really well, on your roof can keep your roof much cooler and it's as helpful for keeping the earth's temperature down as the equivalent area covered with snow up north, but of course it's year-round. I want to do some experiments with this.
@@alexcarter8807 I have got to remember this, absolutely genius.

@@Pistolita221just screenshot it that’s what I did
Excellent video, thank you. But I feel that it’s important to mention the Great Lakes region. Specifically the area of Southwestern Ontario where I grew up. The actual temperature is surprisingly high, at times even higher than desert areas. But it’s the humidity levels that are truly shocking. Guesstimate that for half of the summer, it’s so humid that you kinda feel soggy, like your walking around under heavy water and your skin cannot breathe. When it’s really bad you feel like you can’t take a full breath. It’s oppressive! Being Canadian you expect to receive cold weather advisory texts from the government in the winter BUT the last few years people have received a tremendous amount of heat warning advisory warnings. Southwestern Ontario cities have had to create cooling stations (for those that do not have air conditioning) and misting stations for anyone just walking around outside. Not what most people outside of Canada first picture!
I’m very surprised that this area, even if looked at from the American side of the water, was not highlighted for the combination of the 3 factors and almost unbelievable “feels like” temperature. That area has always been hot and humid but the temperature and humidity rise higher every year. When I was a wee girl central air/air conditioning was considered a luxury. These days it’s a necessity! like a furnace in winter. Honestly it’s pretty terrifying.
I really appreciate this video. I actually have a degree in atmospheric science, but was not aware of the details about the wetbulb temperature threshold the body can handle. I am from Georgia, which I always thought of as being super hot. I now live in mid-Missouri, and I thought I had become much less heat tolerant or something, but this makes me think it's just the wetbulb difference.
How have you found the atmospheric science degree to be? Did you find a job in that field somewhere and do you feel it's valuable and pays well?
What a waste lmfao
Degree in atmosphere science and no idea about wet bulb? Hmm
Suddenly, I love the unstable atmosphere of the southeast in the summer. Pretty much by midafternoon most days you’re gonna get storms pop up and it makes the temperature drop by a good ten degrees
and sometimes it just makes it steamier
Someone also from the southeast here, YEAH! It's amazing going outside after a storm here (considering I'm also someone more physically and mentally adapted to cold environments, my body produces a lot of heat on it's own and I don't need damn more!) bc it's nice, cool, and properly damp. mmmmm.
@@quasar42069 I like that it prevents it from getting hotter than it is, but it does get supper muggy afterwards
That’s pretty naive. It’s nice until the second the sun comes back out the. It’s worse than before. During the summer rain tends to come in smaller showers so it never lasts long enough.
Maybe other years but not this year. With El niño, in Florida it used to have every day an afternoon shower to cool. Now we get these huge storms that roll in for a half an hour lots of thunder and lightning with no rain. Then back to more heat. It's going to be a brutal summer this year
I think it is nuts, that we have these channels like PBS Terra here, trying to get these warnings out about the way our planet is changing, what it means for us humans, and how to save the lives of older people, and vulnerable people, by explaining this to all of us. But we have people that want to say this isn't a problem. And it's always the not so well educated in these subjects that think like that. And it's a pretty large percentage of the population. And you cannot get any of them to watch anything that refutes what they believe.
There is overwhelming evidence this global warming cultism is all complete BS. You are just one of the ignorant sheeple repeating those lies The oceans have risen nearly 400 feet since last ice age without the so-called evil man-made CO2. But individuals like you are clueless to this reality and will even ignore those facts. Truth is ice ages are a greater threat to mankind than interglacial warming. Much of northern half of North American continent was covered in glaciers a mile thick. How much food do you grow under such conditions? Answer zero.
There is video here on YT showing ice core drilling study after which they insert a highly accurate temperature probe down the hole which can detect temperature variations over thousands of years. Reality check. There were periods of greater global warmth than today subsequent to last ice age. The real issue is more people are living in regions that were once considered inhospitable but made hospitable by invention of air conditioning and refrigeration. Also, obesity is increasing in U.S. along average age so heat tolerance is greatly reduced.
You want me to cite credible sources I will but most individuals such as yourself will only seek out information that supports their existing beliefs.
The real issue threatening humans is global overpopulation and resource depletion. If you don't think doubling population from 4 billion to 8 billion over last 50 years isn't an issue then you really have no common sense. The elites realize that overpopulation is an issue because the lack of resources will eventually hurt them through greater global conflict. They also know that mandating levels of procreation will be futile. The easiest way to limit population growth is to eliminate abundant cheap energy.
Yet, the science informants ignore telling us the facts about the global next gen drone shell, the experimental artificial sun, and all the white phosphorus weapons, to name but a few unmentioned facts.
How about the Terraformers set up for Nasa to make streams on Mars, and the led water marbles NASA has been experimenting with, but claim, to have just, "found" coincidentally on The Moon? That has nothing to do with stressing the environment?
ss eugenics drones are NOT protecting the vulnerable~ only, the opposite, actually...how long must the govts scientists experiment on the human genome for nasa?!?
So, the short version of what you're saying is that there's far too many stupid, ignorant morons out here running around loose. Hasn't that ALWAYS been the problem?
My sibs & cousins! 🙄
I'm from Eastern India,the summer temparatures go beyond 40° easily. One thing I've noticed is when the humidity goes beyond 50% it becomes uneasy. I have never experienced this kind of heat .
When humidity hits 95% or more, the "feels like" grows exponentially with temperature. At that humidity, 40° will feel like 80°, and 50° will feel like 190°. It doubles at roughly every 9°.
Get out of India. Climate change is gonna kill hundreds of millions of people
Get out of India or any parts of south asia.
Here in Kerala during noon it's 42 degrees and humidity 62%😑
So glad i live in way northern Michigan, artesian flowing well 24/7//365. Nice and cool most of the time,lots of game and great fishing!!!life is sooo good😊
I think it's crucial that web bulb information be given in weather forecasts. It seems to be equally important as dew point, which is yet a different measure of humidity
So right. %RH is almost entirely meaningless to humans. Wet bulb temperature is what we should always use, as it directly measures total heat (sensible plus latent). Dry bulb temperature only measures sensible heat. Useless, since humans live in the real world, and we can ONLY cool using latent heat transport via sweating.
The weather forecasts now show the same weather we've always had only in the color red instead of blues to psychologically manipulate the viewers into thinking normal weather is red-hot.... Ridiculous what people will fall for.
Bro I would be happy if they just gave the dew point instead of relative humidity.
I've heard the phrase 'The heat index is .,' or, the 'Real feel temperature is ..,.'. Before, I discounted the panic in the weather reporters voices as 'overly dramatic'. Now I understand how vulnerable people actually are in summer heat waves. Sobering.
Do the Dew
Actually, over 20 years ago, the IPCC already predicted that a continued warming would lead to ever increasing regions on earth where it's just too hot to be able to survive.
Mankind didn't stop climate change and here we are.
Honestly, thank the oil industry and the military industrial complex the world over.
Mankind didn't create it, either.
As Earth approaches the peak of her FIFTH Interglacial Warming Period over the last 420,000 years, we're reminded that all four prior periods experienced hotter temps and higher seal level rise as the result of greater glacial melt, even those humans made no contributions! These cycles are both NORMAL and NATURAL phenomena produced by variations in eccentricity, axial tilt, and precession combined to result in cyclical variations in the intra-annual and latitudinal distribution of solar radiation at the Earth's surface, and that this orbital forcing has resulted in nearly 10,000 of such periods dating back to 1 billion years.
So long as you remain highly myopic, focusing on the last 30,000 years, YOU WILL NEVER SEE IT.
By viewing a 500,000 year span of time, however, comparing the current period with previous ones, it becomes abundantly clear that we're in nothing more than a normal and natural Interglacial Warming Period.
And, yes, I have performed time-phased analysis of full-cycle rises, peaks, falls and troughs for all five Interglacial Warming Periods occurring over the last half a million years, along with Fourier transform analysis of the contributing factors. Looks like Earth is in a double-period, where the two most prominent contributors are located close enough to cause a period, but not close enough to produce a single peak. This last occurred 220,000 years ago, and before then, 595,000 years ago, both when the eccentricity was high but the axial tilt was low. This condition results in warming periods with subdued but prolonged forcing. Our current period has a prolonged and low eccentricity, the lesser factor, but high axial tilt.
There exists absolutely ZERO indication in the data to suggest the current period is being caused by anything other than Milankovitch cycles, except for a minor accentuation of CO2, but without causing any additional temperature rise over the previous four periods of the last half million years.
The audacious claims of the "climate crisis" people attempting to extort governments for trillions is absolutely astounding, if not mildly infuriating to data scientists whose adherence to numerical integrity isn't troubled by trying to cram the data into some agenda.
Which means it’s gonna get a lot more crowded here in New England
@Kelly Harbeson Because scientists are liberal, aesthetic virtue signaling cucks too worried about their own fantastical sense of professional respectability and "not wanting to cause mass hysteria / be alarmist" and not actually progressive or genuine critical thinkers. Again, they've always been too worried about being perceived as "biased" by a demographic segment of the broader population that is utterly right-wing biased themselves, so I honestly have no idea why the technocratic consensus is to try and communicate rationally without any emotion or passion. Like, yo, dumbasses, real humans aren't logical, rational creatures devoid of emotion. Lmao. If you want to communicate the need to overhaul our entire socioeconomic-ethnic system to prevent literal global catastrophe, maybe you should be ACTUALLY COMMUNICATING THAT. But alas, scientific principles apparently dictate they can't conclude with sociological conclusions in non-sociological papers. That leaves the IPCC to be left to say what every scientist WANTS and WANTED to say, but couldn't, because of degenerate, dumbass conservative logic about "being alarmist."
Also, even considering my above statement, it's genuinely moronic to assume that no scientists and none of their climate papers made the claim that massive overhaul was necessary. They just don't say explicitly or directly. They do it in dumb, beating-around-the-bush scientific ways of, again, maintaining their perception of being some kind of aloof, purely technocratic entity. Conversely, if you actually talk to them as actual people, outside of their written statements in published papers and surveys, they are incredibly straightforward about what needs done, and have been for the past 50-60 years: end the fossil fuel industry, and, ideally, end capitalism itself entirely, as capitalism is fundamentally what is responsible for said hydrocarbon industries and for how it has been possible for them to evade being obliterated 60 years ago: because it's profitable for shareholders, and under capitalism it is anathema for a government to do or even THINK OF DOING anything that can be perceived as "redistribution of shareholder wealth." By gosh golly, that smacks of communism, don'tchaknow!!!!1!
Honestly, the ultimate issue is that America has wed itself to capitalism thoroughly, rendering any alternative to capitalism and any problems that require solving the problem of capitalism simply utterly and entirely politically infeasible to even suggest to red scare-laden Ameriboos.

What a crock! It has been colder than normal on the West Coast of the US
@@GFY11 The OP was talking about a 20 year time span, not the past month.
The map for the 6 out of 10 makes sense to me. It's all river valley floors. Mississippi but also the Illinois, Ohio, Wabash and Tennessee River valleys. Lots of surface water and somewhat protected from prevailing winds. And the climate in a lot of that area is classified subtropical. Even Chicago makes sense. When the conditions are just right (or really wrong), humid air can be carried in from the lake and just sit on the city. Plus, summers are consistently getting warmer and there's already a massive heat island effect there.
There's also a thing called corn sweat or evapotranspiration that explains Chicago as everywhere from Western Nebraska to central Ohio and Michigan for hundreds of miles is pumping up thousands of gallons of water per acre into the air every day. And wet bulbs have reached 30.5C/87F in various locations such as Bettendorf, IA, Rochester, MN, and Decatur, IL in various heat waves from such an agricultural event.
@@Eibarwoman I've never heard of the term corn sweat (which I admit struck me as funny), but I get that. I have noticed how heavy the air can feel from the moisture during summer if I make a pit stop driving between cities. I live in Springfield just west of Decatur and we've had some of those same heat events.
And they all build on each other too. The corn sweat, geography, prevailing winds and heat islands. Then add in the moist air coming up from the gulf right up the valley. We're right in the crosshairs.
Chicago is a concrete jungle, as are most large cities
@@infinitejest441 There's also the stuff lurking in places like far Southern Will County which grows in stalks and spews water and a big body of water next to Chicago which also amplifies humidity. The urban heat island when combined with lake humidity and corn transpiration is a troublesome hazard.

Hbomberguy has Flat-Earth, Vaccine-Denial and YOUR Beliefs... covereddd.
Also known as dew point temperature, the meteorological term. It is basic meteorological knowledge that warm air has the ability to hold more water vapor than cold air, and that if you cool a parcel of air below the dew point temperature, condensation will occur. Heating up a parcel of cold air will dry out the air, until eventually enough evaporation will humidify the air again and the process repeats itself.
Not quite. The dew-point is the temperature at which water vapor in the air will start to condense out.
The wet-bulb temperature, however, is the temperature that you can reach _by evaporative cooling._ They are certainly related, as both are a function of the water-vapor content and dry-bulb temperature of the air, but they are not the same.
I finished grad school and changed careers 25 years ago, so it's been a while since I've looked at any of this. But my sense is that the wet-bulb-temperature of a given parcel of air will be higher than the dew-point, since I expect evaporation to cease before the water-vapor content reaches the point where it starts condensing out.
Because of a genetic disorder, fibromyalgia and being a type 1 diabetic, I’m heat intolerant. I go from being perfectly comfortable to unbearably hot (surface of the sun) in no time at all & once I’m that hot, it takes me forever to cool off. I’m always super careful as the weather gets warmer.
Wow that sounds incredibly tough to live with. You should look into moving to a state that doesn't have frequent high heat spells, like the west coast or extreme northeast, Maine, Vermont
I'm sorry that you're in that position of medical issues.
Had heat stroke in a diving suit while waiting for others to get ready. My body shifted into low speed within seconds and nothing I could do would make my muscles move faster. Very odd experience.
No you didn't. Heat stroke is BODY temp of 105, and near 1/2 die. The remainder tend to have permanently damaged brain and organ function.
What you had was heat exhaustion, hyperthermia at a lower level, where brain function , sweating, etc. cease for only a short period.

I’m not surprised to find we are at highest risk of a wet-bulb event. Our heat indexes are consistently in the triple-digits, even up to 123F.
If you live in the Texas Gulf Coast SSE of Houston, be extremely careful. It doesn’t have to be wet-bulb conditions to take you down. Be especially careful if you’re over 65, as I am. I learned that I’m not as heat-resistant as I used to be. It was a very unpleasant surprise.
I know I don’t speak for all my fellow boomers, but we do need to stop doing our own stunts. Stay out of the heat, if you can. Stay hydrated, and don’t forget to eat.

@@kimlibera663 Water vapor levels are limited by temperature. Water vapor is not a driver of temperature. Therefore something else is driving temperature upwards.
@@jaykanta4326 I did not say water vapor drives temp. It does drive climate & it is being reported that water vapor content is up (via evaporation). Warm air will allow more storage of water vapor in the air aka it's not the heat, it's the humidity.

How about the staff at our favorite eating establishment? Tons of humidity from cooking and dish-washing, plus the heat and humidity from food prep. Or, when you have 25 or more water-vapor-producing-humans in an older school classroom in August, complete with houseplants? What about anyone working the greenery with machinery; when does the sweat start burning your eyes because you are wearing safety glasses? I worked in a greenhouse during a power outage; 118 deg F in the shade - all I did was hose down myself and anything leafy for the good part of a summer afternoon. How about anyone working on a roof, or repairing the asphalt street?
I'm a warehouse worker and the building and trailers I work in are always more extreme in temperature than the outside atmosphere. On an 85 degree (F) day 90% humidity, a trailer is nearly 100 degrees and the concrete absorbs and expells the moisture everywhere. We're expected to work full 8-12 hour days in this extreme environment. I predict we'll eventually see laws prohibiting companies to make employees work a certain amount during the hottest days. The crazies part is I live in New England so it doesn't even get as bad as other parts of the US. Best of luck to all the labor workers.

Planting more trees might help in some areas, but of course this really has to be large scale and we need to commit to it over the long term. Trees do help to sequester CO2, and this could make a difference. Trees might help to cool urban areas with a lot of concrete that soaks up that dreadful heat and radiates it back to us. They also might help turn arid deserts into more friendly places for grasses, plants, and other trees which can reduce temperatures. At this rate though, I think we're making the earth much friendlier (temp-wise) to reptiles than to mammals. That chart she showed with historical temps matching humans' time on earth was pretty telling.
you can't just plant trees and expect them to survive. One of the issues we're seeing in the US West is that massive expanses of trees are just dying. Every year we find thousands of acres of dead trees because they're too dry.
And make sure those trees are diverse and native
It’s astonishing what a difference trees can make in the local temperature. I don’t carry a thermometer around, but going into a neighborhood with a lot of trees is such a relief in the summer. It can go from unbearable to comfortable immediately.
Agreed. We need more shade in general across human settlements. As humans (especially white people), the sun's UV rays can cause a lot of harm to our eyes and skin, so having shade from trees and other structures not only helps with the temperature, but protects us from melanoma and eye damage.
@@wolvesrfun People can save an incredible amount of money on cooling costs by having trees planted around their house. You have both direct shade and transpiration effects, which literally sucks heat out of the air nearby. So when someone cuts down a large tree, they not only increase their bills, but their neighbor’s bills.
Ive been wanting to control my AC by wet bulb temperature for years. It baffles me that no thermostat can do it.

Some thermostats control for both humidity and temperature... I know that Carrier makes such a design, there are others.
@@9UaYXxB like which brands? Are any retrofittable to my AC?
THERMOstats only respond to temperature. That's why they have that name. In order to respond to humidity as well it would need an additional sensor.
I was born and raised in FL and the weather changes hourly there. It’ll be hot and sunny at 2 pm, by 3 pm it’ll be cool and cloudy, followed by a sunny thunderstorm.
Although I let town climate activists put a climate change sign in front of my house this report leaves me wondering. As a kid I used to live in Orlando Fla for about 6 months in the early 1960s.. The summer days were routinely hot and humid. All I can recall of the south is hot wet weather with a massive violent thunderstorm like clockwork every early afternoon. It would scare the daylights out of my mother and she'd take me and my sister into the hall away from windows. The evenings would still be humid but bearable after the sun went down.
We were only there 6 months and perhaps was why we didn't stay longer?
What I find very noticeable since those days is the conspicuous lack of flying insects on my car windshield. I live in New England now and there used to be more bug juice even 40 years ago but I can't really recall the change.. People used to have to clean their windshields in gas stations. Sometimes attendants would offer to do that as a perk. In the south the windshield and grills would be plastered with bugs and long winged things up to 3 inches long. There also used to be many more toads on the roads after rainstorms up here just 30 years ago. Every summer rain would entice them to seek warm, dry pavement. Just driving out of this neighborhood would smash hundreds of them. I hardly see any now and the woods do not make the racket of noise they used to. Instead I have tinnitus that sounds like the sound I used to hear outdoors during the summer over 50 years ago.
I think what that means in "Silent Spring" Rachel Carson's warning about pesticide use may have been ignored elsewhere than the US and Europe. Increased road traffic just reduced the population of toads year by year. Everywhere is interconnected so it didn't really help much. I see very few insects or birds anymore.
To me that's more ominous than climate change.
I cannot even imagine tolerating these temperatures and humidity 😱 I live in Norway and the times I get to experience anything above 30C is suuuper rare and short (usually just a week or two when visiting south of europe for holidays, but we never go in peak summer usually we go in may or september 😅). I think I will just fall over and die immediately 😅
That's because you live in Norway.
If you were born and raised in a hot and humid climate, your tolerance would be different.
This is true ☺️ Same for people from warmer climates visiting here, they freeze when it is only a few degrees C below zero which for us is not such a big deal 😅
Its gets above thirty every day where I live (Philippines), nobody dies or falls over.
Its very uncomfortable to be outside in the sun, you have to seek shade, but 110 million people handle it. (might be some genetic adaptation since Filipinos do not sweat much).
@@glidercoach you can't just "tolerate" some temperatures. Your attitude is exactly why so many people die during these events.

Then as you age your ability to withstand these temperatures drops pretty quickly, which is why so many elderly folks pass away during heat events. They think, "I've tolerated this before. No big deal." and they die.
@@CRneu
If you bothered to read the comment directly above yours, you would realise that what you wrote is in fact wrong.
Everyone is different and everyone has the own unique tolerance to heat.
At 100% humidity it doesnt neccessary mean its raining, it means no more moisture can enter into the air, therefore your sweat cannot break down into steam to cool you, because there is too much moisture in the air already.
At 100% humidity, 40°C feels like 108°C.
At 100% humidity, 45°C feels like 153°C.
At 100% humidity, 50°C feels like 220°C.
At 100% humidity, 60°C feels like 470°C.
It only goes exponential from here on. That's why all it takes is high enough temperature (>35°C) and maximum humidity to kill you. Remember that heat index is an _exponential_ function, and you know how scary exponential growth is??
People have been dealing w/ heat and humidity for a long time now. Those that live in that type of climate become accustomed to it; but overheating your body is no laughing matter, and I would not fare well in that situation. Perhaps life near the poles is in my future; or at least somewhere closer in vicinity to them....
18 years ago in San Diego a southern flow of air from the south to the North brought humidity into SDcounty and has been steady ever since, San Diego humidity is generally 83% which is horrible in the summertime, not so noticeable in the winter months, however after a being a 35-year resident, moved to the desert where it's 4% humidity•maybe 100°how ever feels more like 88 degrees.
There was a couple days that may have been wet bulb last year where I live in MN. I was out for maybe an hour and I was already feeling heat exhaustion. It’s no joke.

Wet bulb isn't a specific temperature, it is a method of measuring, one which 'captures' the capacity of the air (at 'any' temperature) to evaporate moisture.
Given the choice between finally doing something about CO2 and protecting the “economy”, I have a bad, bad feeling that we’re heading for “thoughts and prayers” at epic scale.

It's a growing economy that generates the wealth that protects humanity. Inexpensive reliable energy created the unprecedented economic growth that led to the modern world. It's the modern world that keeps you safe. The modern world mitigates and neutralizes threats from warming, and in fact threats from everything.

I feel like the simplest option would be to construct heat shelters below grade in places with high risk. Use the naturally cooler earth to provide refuge from the heat when it gets bad.
That's a very logical idea, but many of the areas with the greatest risk for high wet bulb conditions are also at low elevation and are especially likely to experience hurricanes and severe storm surges. It's like you just can't win in those places.
@@TheNotehead Good point. And really there is no need to make it below grade. It just needs to have enough thermal mass that the interior temperature ends up being a long-term average temperature rather than the current temperature, so building up a bunch of earth around and on top of the shelter works too.
Go underground time proven solution.
Coober Pedy, Australia on a much grander scale.
Another consideration is to ensure access to swimming locations, be it natural like a beach or lake, or an artificial pool. Immersing yourself in water thats below 80°F is certain to cool you down enough to be protected.
However, i recognize that saying "everyone should just go swimming" isn't a complete solution, but it would be a compliment to a heat shelter program.
And we need to consider worker safety regulations so that people aren't forced to work themselves to death outside during these events where just sitting in the shade is too hot.
As a teen growing up in Kentucky I would help harvest tobacco as a seasonable job. I was in peak physical shape but the first day I did this work I was walking along when one of the farm managers took me aside, handed me a gallon of water, and told me to go sit in the shade. I tried to protest and he would not let me continue. I didn’t realize I was wobbling and swaying as I walked the field doing the work. Later, as I sat in the shade I got one of the worst headaches in my life and felt very nauseous. If he hadn’t intervened who knows what would have happened. Heat stress is not something to play with.
Get the leaders to do something.
We can't stop wars, can't stop climate challenges and so much more.
I'm currently watching this video while the heat index in my area is hovering above 40°C. The sticky, muggy feeling is so uncomfortable.
The real nightmare is that electric utilities are trying to avoid lawsuits by shutting off power when the weather gets too hot so that they aren't blamed for fires. So unless you can generate enough power to keep your air conditioner going, you are in a bad spot.
Good point....
I seriously doubt the intentional blackouts are to keep fires from starting. They're done to keep the system running when demand is too high for the generating capacity.
Thankfully it would take a long time for the wet bulb temp inside to reach the same as outside. Air conditioned spaces are cooler of course but also dryer, which also lowers the wet bulb temp.
There will still be issues with it though. If the AC wasn't on before the power was cut or if it dies for multiple days or anything else it can still be dangerous.
That being said, I expect power backups to become more common. Hopefully solar power.
This humidity in Chicago is unbearable 🥵
We were camping in Anza Borrego. Overnight the humidity soared. We woke up at 5am and we threw the equipment in the truck and we ran away. We were close to cramping, and we were panting by the time we got in the car.
Yesterday in 70 degree weather i was sweating bullets.
It wasn't even hot and it was overcast while working outdoors.
have u thought about going to the ppl that mfg's bullets then - or even join the army if ur sweating bullets 🤔🗿🗿

I was in England in 1976. The temperature got to 85 degrees Fahrenheit and the hospitals filled up with people who had heat stroke and heat exhaustion. Just coming from Louisiana where the temperature was in the 90’s this made a huge impact on me. I will never forget it.
go to shanghai in summer and you will feel hot and humid 100F
Very interesting! When I was in college in Chicago in the 1970’s, I worked at Marshall Fields downtown store, at the sunglasses and weather instruments counter…where we sold sling hygrometers - which I never really understood….but now I do - Thanks!!
Here in Missouri, I've noticed our incidents of drought seem to be increasing. In 2012 we were hit with one of the worst droughts the state has ever seen, and now ten or so years later, we're getting hit with another one.

Very usefully informative - I'm a Brit living in subtropical SE Asia where I have to contend with seasonal hot and humid weather. Things may be especially difficult if the next spell coincides with a strong El Niño ENSO state.

I grew up in dangerous wet bulb temperatures in central Florida. No AC and no heat in the 50s and 60s. Just lots of water and locating cool places to enable heat exchange. Usually on the clay banks of a shaded creek with our extremities dangling in the water or rolling around on the tile floor on the northwest side of the house. The parents worked in air conditionedoffices. Our schools were not air conditioned. I love hot weather in the plains states. We called that a dry heat.
When I was much younger I worked as a botany tech in the Forest Service. As such, we techs had to work almost every day outside in various sites. We would be forbidden to do our work outdoors when the temps got a certain amount in the 90s F. 140-something is unimaginable! 😮
Edit: 178 F!
When I moved to NYC many years ago, one of the first things I bought was a window air conditioner, because I couldn't tolerate the high temperatures combined with high humidity in the summer. I couldn't have lived there - literally could not have lived - without that air conditioning. I got sick quickly if I spent much time outside in that weather.
Very informative on a topic I had never heard of before. Thank you for your research and public video😀
Yup I was gonna say Nashville has to be included in this. 90+ degrees with 50-70% humidity depending on time of day. Honestly brutal. I’m used to 100+ temps in Texas but usually the humidity is a bit lower. My cars ac is out, pray for me y’all
I live near some of those parishes (we don't call them counties) in Louisiana, and I used to work outside during the hottest parts of the day. I remember two times (in consecutive years) when it felt like I was breathing no oxygen at all, and I legit had to sit inside in the AC for half an hour (just staying hydrated has no effect, because like the video says, sweating doesn't work). I have no idea what the wet bulb temps were on those days, but they had to have been close to the limit to get me like that, since I don't smoke or vape and don't have breathing issues on normal days.
Thank God I don't work there any more (not just for that reason), and my deepest sympathies to anyone who has to live (and especially do outdoor work) in places prone to these events.
The work schedule isn't too smart either. One would have to start to work at sunrise, then up till it gets too much (11 am perhaps?) Then go inside and rest. Then, when necessary, start as late as possible again. Better to work 6 days for 6-7 hours, depending on the day's weather conditions.
In the Netherlands, Europe, there are days on which for instance construction workers cannot work due to cold. They literally get paid out of the 'ice days' insurance fund, for which both employee and employer pay a small percentage each month. One could create such a fund for 'heat days' as well. New workers get helped too, even if they didn't contribute much yet.
Here in the Philippines we are used to very hot and very humid temperatures and live thru it like a walk in a water park. But recently it is so unbearable that we currently believe hell was moved here in the Philippines and we are currently living in it.

@@oblobear2093 What I see happening is usually the attractive females from families in struggling countries will seek a working man in the USA for marriage... then once married she is able to bring her family into the USA where they can safely begin new lives. The only other scenario for a family moving into the USA would be if you have a son or daughter who is some type of genius prodigy with intelligence extremely high where universities will allow the son or daughter to study and work within the USA and then the smart son or daughter can eventually afford to bring family into the USA. Many options where to live and where to work once you're in the USA.
I'm in North Central Florida. It was 95° yesterday according to both my thermometers. according to the bank it was 105.... when I put in the 80% relative humidity into an online heat index calculator I got a heat index of 134. so yeah , that wet bulb stuff , that's basically Florida for six hours a day every day in the summer . If it wasn't for refrigeration and air conditioning I really believe everybody in the state just about would just die. Even with air conditioning there's been days that I've actually had to stop what I was doing because I quit sweating come inside and just standing under a cold shower. This is what outdoor work in Florida is like sweating is useless does not matter It just soaks your clothes. It looks like you jumped into a pool. those evaporative handkerchiefs and things like that don't work here because the humidity is too high. BIG fans or air-conditioning and ice is all that saves you from heat stroke .I go through five hats and three seats of clothes in a hot day in Florida. I have to actually look at my pee to make sure I'm hydrated. drink an entire gallon in just the 8 hour work day and it's not enough . this problem is way worse than your numbers imply. My sister HATED the outdoors here , moved to Arizona where it's over 100 regularly and talks about how much cooler it is in the desert vs Florida ..
These past few weeks in northwest Florida have been absolute torture for sure.
The documentary left out that you can easily reach those temperatures in a small apartment without air conditioning if you put up your clothes to dry and a lot of sun is shining in. I think I am starting to understand the heatstroke numbers now. I always thought it is the people outside that are the most stressed.
A lot of people in this comments say stuff like "I did this or that in hot temps and it didn't bother me," you do NOT know what you're talking about. Humidity makes heat SO, SO MUCH MORE WORSE. Take this from someone who lives in Georgia, a state that gets horribly hot and humid. It's torture. Take this shit seriously, and don't fucking die of heat sicknesses/illnesses (heat cramps, heat exhaustion, heat syncope, and heat stroke).
People go hiking all the time here in Phoenix, despite government warnings. Luckily we only get the humidity during monsoons and we get huge cool downs. But once the clouds lift it is brutal until the water evaporates. Nothing like midwestern summers where it feels like stepping out of the shower all day long.
Take it from someone who lives in Malaysia. Tropical all year round, and relatively windless due to being located at the inter-tropical convergence zone.
Few days ago, it was (33C) 92F with 75% humidity. But the humidity is high all year long anyway, just that it's been considerably hotter recently. Don't recall anyone died of heatstroke, until very recently. M
Hot & humid makes it difficult to breath sometimes. Feeling stuffy, "drowning" because of the moisture in the air.
People in temperate climate should really count their blessings while it lasts..
By 2100, given "Business as Usual" emissions, Southeast Asia would be unlivable, not just for humans, but also wildlife. Temperatures exceeding 45°C and maximum or near-maximum humidity.
@@basedoz5745 Yep, I'm a "desert rat" too, and can take those 105/110 + F *dry heat* temps much, much easier than the monsoon humidity, even though those temps are a decent bit lower.
I can't imagine what a 35C wet bulb feels like. Ugh we had a 30.3C wet bulb day last month in my area just outside of San Antonio, Tx (125F heat index) and it was horrendous to be outside.
The book The Ministry For The Future's opening scene is that of a wet bulb even in India/Pakistan from the POV of an American NGO worker. People stole AC units and even tried to escape into local rivers and lakes but even those bodies of water were being heated. It's a wild scene and pushes down the rabbit hole of learning about wet bulb events.
'It's not the heat, it's the humidity'
"Ya, but it's a dry heat!"
This is where treed shade is important. Trees give the feeling that the temperature is 10° cooler. Counterintuitively we need to harvest rainwater, but this is to support tree growth. Planting trees to the West and North of buildings moderates energy use. It creates more livability year round. It blocks the hottest, low west sun and acts as baffles to wind in winter.
Adding trees to street and parking lots via bioswales also adds cooling, reduces heat island effects, etc. This saves on paving costs, and adds walkability and bikeability.
Farmers need to switch to biome-appropriate, alley-cropping to protect soil, plants and livestock. This also increases food and byproducts, and adds farmer/rancher resiliency
Tree pollen is good as it helps bring down humidity in the form of rain.
This also recommends denser, gridded rail, rail allows water permeability that paving removes, while adding equity.
West and South when you're in the northern hemisphere.
@@aluisious
No, you want a generous overhang instead of trees to the south. Midday sun is high, hence overhang solves that. Late day sun is the most brutal, in the northern hemisphere.
Even Feng Shui understands that.
Window placement is important as well. Large windows to the south to exhaust hor air, and smaller/fewer windows to the back to create convection in moist, hot conditions.
Trees to the north protect from harsh winter winds. Most of the Northern Hemisphere is still located in areas with harsh winter winds.
@@aluisious
Usually a 4' trellis shading windows during the summer is a cheap retrofit.
Trees cool the air by evaporation. If the humidity is high enough, there is no evaporation.
Trees help a lot in many circumstances, but not in high wet-bulb situations.
@@vanlepthien6768
Trees still cool even in humid climates.
It is a false statement to say trees cool by evaporation. I live in a high humidity environment and trees do cool even when the air is 'wet.'
The average temperature in Malaysia during the day in 1986 was 26 Degree Celsius.
It was very comfortable during that time
Today it is average 31 Degree Celsius. It is too hot now.
Few years ago it was increased to nearly 40 Degree Celsius.
It is not good for the health and for the children.
Heatwaves are set to kill 10 million people a year by 2040, and up to 90 million people a year by 2100. Southeast Asia will be one of the worst affected regions.
Thanks, capitali$m, your worship of money has killed more humans and animals than all other ideologies combined.

When i was in the navy they taught us a lot about how dangerous wet bulb can be. It is scary stuff that you dont mess with
I wonder what we're going to do when all of mexico and the southern USA is a wet bulb
I’d like to know how these events affect the wildlife.
Wildlife across the entire northern hemisphere, representing an incalculable number of plant and animal species endure temps that go from over +35C to more than -35C every 6 months and then back again. Nothing dies. Whales migrate from Arctic waters down to the Sea of Cortez to give birth each year and migrate back. Crocodiles that swim in vast rivers in Africa, roll around in mud during the dry season. Canada geese have stopped flying south in my lifetime during winter because they have access to food.
Today all living things across the entire northern hemisphere are enjoying unprecedented habitat *expansion* for the first time in the modern world. All because of warming.
The greatest diversity of life on Earth lives in the tropics not in Antarctica or Greenland. Cheers.
I'd like to know more about that, too. But I do remember hearing about the mass deaths of bats in Australia several years ago (~2019 - 2020), due to unusually high temperatures they just couldn't cope with.
Estimated in 2010 we were driving 150-200 species extinct every day. Once abrupt cc really kicks most species won’t be able to adapt to the rapid changes
@@Jc-ms5vv Who estimated this in 2010 and based on what levels of omissions.
@@raclark2730 According to the UN Environment Programme, the Earth is in the midst of a mass extinction of life. Scientists estimate that 150-200 species of plant, insect, bird and mammal become extinct every 24 hours. This is nearly 1,000 times the "natural" or "background" rate and, say many biologists, is greater than anything the world has experienced since the vanishing of the dinosaurs nearly 65m years ago. Around 15% of mammal species and 11% of bird species are classified as threatened with extinction.
3 months later and I’m seeing this. Crazy we are going through a pretty weird humid heat wave here on the Monterey bay. Partly from this tropical storm Hilary, partly from El Niño, but still weird. And hot. It’s 10pm and still 70° here. Usually would be about 20° less
I don't know how hot is considered a hot wet bulb, but in eastern China there's regularly about a month of mean 28C Tw every year, and the annual peak Tw is usually at 42C (107.6F) in the Yangtze river valley (Chongqin, Wuhan, Jiujiang, Nanjing etc). That's because of a combination of the North-Pacific-high, the Tibetan plateau bending the westerly-wind-belt, and the dense water vapor from the great river.
The biggest danger is the power grid going down in such conditions which would make AC unavailable. F. Miller
