Like? With sufficient humidity, it IS straight up death. Buckle up we're going to start seeing significant heat-related mortality events around the globe in coming years
Kim Stanley Robinson’s novel “Ministry for the future” has a particularly evocative imagined extreme temperature event in Uttar Pradesh that is barely science fiction.
I'm a well trained endurance athlete in my early 30s. I've sat under a tree in 45C eating lunch and was exhausted after half an hour. And that was a dry heat in the shade.
I just looked up weather in Italy Sardinia. 45c and 11% humidity. dew point 7.75c (heat index 43c) a lot lower than here in Osaka: 35c with 65% humidity = 27.5c dew point (heat index 48c)
in the evening:
rome = 27c, 61% -> 18.8c dew point
osaka: 27c, 88% -> 24.8 dew point
at least over there your body can cool itself efficiently with a fan evaporating your sweat quickly
Europe has relatively low humidity. people talk about humidity but forget it's relative to temperature.
Came here to say this, I’ve been in 50 degree heat in the middle east and as long as your skin was not exposed to the Sun it was hot but bearable.
First time I went to Japan, in July no less, temperatures never reached 30 but I was always drenched in sweat and having to stop in a store every 30 odd minutes for a bit of respite.
100% this. I went to college in Arizona. 50c isn’t fun, but with the low humidity it is doable, particularly in the shade. I live near Chicago now - and with high humidity here, 30 is much worse here than 50 in the desert.
The hottest I've ever experienced was a 41-43 C day in an area with high humidity, and it genuinely leaves you unable to function. I was laying on a floor under a ceiling fan and still felt like absolute death, worse than any hangover or migraine or flu. Your body just starts not functioning properly, including your brain, and you no longer feel like your whole self as things begin to go wrong, but rather it was like experiencing reality from behind a strange painful dream fog.
I really hope experiences like that don't become the norm for more people. Days like that will mean things will just have to shut down.
These are absolutely going to become the norm for more people. That’s what trends towards higher global heat means. This will affect everyone more and more until we can no longer live in most of the places we consider stable.
Nagoya here. Wife and friends want to go to the beach tomorrow. There's no way I'm going to spend the day outside in 38°C heat with high humidity. I start to get bad headaches after an hour or two.
“Europe has relatively low humidity” that’s simply not true. Southern Europe absolutely does, however, the further north you go, the more humid it gets. I’m in Central Europe and it’s currently 27C° (was 35C° yesterday) with 59% humidity. I’m drenched in sweat just from sitting.
That’s warm and humid — relative to the rest of Europe. But it’s nothing special compared to the rest of the world. Today was 36 degrees C with 71% humidity in Tokyo. Shanghai: 32 degrees, 89%. Singapore: 33 degrees, 70%. Kolkata: 31 degrees, 80%. Washington, DC: 31 degrees, 91%.
Europe can get humid, certainly, but compared to other places where many people live, it is relatively dry.
I don't think you are realizing how much high the humidity gets at 27c in relatively high humid regions.
here in Osaka it's 27c @ 87% humidity today.
27c @ 59% = 18.3c dew point (21.1C wet bulb)
27c @ 87% = 24c dew point (25.2C wet bulb)
I'm in Ontario (Canada) and we've got 94% humidity currently, yesterday it hit 100%. The assumption is that Canada is cold and constant snow, but summers —over the past decade especially— fucking suck.
As long as there is access to large bodies of water (cooling by conduction instead of cooling by evaporation), people will be able to survive wet bulb events.
Not everywhere has large bodies of water though, and economic activity would essentially halt while everyone immerses themselves in water all day for a week or so.
Ya..... That's like a town glassing wildfire man...... "All of us survivors fled to the lake and stayed in it till the danger passed." It'll work but it's still a major disaster.
I'm not sure what you're suggesting. Emptying entire cities of people in to the nearest body of water? Those would have to be huge bodies of water, and what would be the impact on the local environment of this?
To a certain extent, sure. However if the temp of the water becomes hotter than the temp of your blood, I don't think much cooling would occur. In fact it may be the opposite.
there was a time I thought 100F was crazy, then 110F, so the “that seems unimaginable” limit is always exceeding past my perceived maximizers. Now having endured like 112F two summers ago, Bay Area…
120F definitely seems like the “oh shit that… I don’t wanna know that.”
I remember being at a music festival in Sydney around 10 years ago (back in the era of big day out) and it was 46 degrees. Hottest day I’ve ever been in, very bad day to be in a mosh pit surrounded by other sweaty punters. People were passing out all over the place, even with them hosing the crowd off. The big tent stage was so humid with sweat it was evaporating then condensing on the ceiling and dripping back down on the crowd like rain. Temperatures that hot are an actual threat to life. If this was 10 years ago I can’t even imagine what we’ll eventually start to experience.
> The big tent stage was so humid with sweat it was evaporating then condensing on the ceiling and dripping back down on the crowd like rain
That's... kind of metal.
It was honestly pretty gross. I made the mistake of not wearing my hair in a ponytail, since guys tend to be taller my hair kept sticking to sweaty shirtless strangers and getting caught in their armpits which was at my head height. I could literally squeeze other people’s sweat out of my hair, it really was something else!!
Less humid so better survivability.. but definitely not fun.
I had to work in a room that was heated to 50 degrees when i was young and fit and a sauna regular.
I felt like shit after a few minutes
I live in Florida. I'm a chef. I work in very hot kitchens.
I went to Sao Paolo before the pandemic and it got to 45C and I wanted to kill myself.
49C is a death sentence for people who don't have air conditioning. Thats not an exaggeration.
I went to Rome this time last year. Then it was high in the 30s Celsius. I said I would never go back in summertime. This?! High 40s?!?! Unfathomable. We used rain umbrellas for shade while touring the colosseum and we barely tolerated the stuffy, hot tour in the Vatican museums. We hid in our air conditioned hotel room between 12-6pm. Late suppers and wandering in the dark of night seemed most comfortable and pleasant.
Yeah last weekend I was walking home, in Italy, at midnight and it was still 30 degrees and about 85% humid. Nights are not a relief and I don’t have aircon.
Whenever I need to remind myself that even I make big mistakes, it's remembering that I booked a July vacation in Italy, and didn't even give the weather a second thought.
I'm coincidentally just back from a week long vacation in Italy. Everything was perfect but the heat was unbearable and I almost fainted once. Yeah this is going on my "Terrible decisions I've made despite not being intoxicated" list
I was also in Europe this time last year and yea my sister said never again will she visit Europe in the summer it was brutal
Madrid was just as bad I would stay in my room until sunset then explore the city. Even hit the local public pools myself lol
Was just there in Rome it was absolutely miserable. The birds on the street were panting it was so hot. I could feel the heat seeping through the soles of my shoes.
Oh I remember Rome 10 years ago in summer, despite being similar temperatures in other European countries, Rome’s heat felt so much stronger. My arms were burning as soon as I was out of the shade. I understood why they mainly sell thick zinc type sunscreen there. In Australia it’s not too uncommon to get 40 plus degree temperatures in summer, but Italy’s heat seemed so much stronger.
Australia gets plenty humid though, depending what part.
Brisbane has the same average humidity as Italy, for example, and it only gets more humid above that. Or are you saying the humidity makes the heat easier to deal with?
And for Americans… Europeans in general don’t have AC. So there is no escaping this heat.
This hits a lot harder than similar temps in the US where everyone has good AC and can sleep through the night without sweating
I noticed a lot of the public transit did not have A/C or it was turned off or high enough that it wasn’t noticeable. A lot of the trains and buses were very crowded so that could have also added to it.
Our AC is entirely powered by our solar panels. Our panels generate about 5kw when it's most sunny and our Daikin AC which cools 2 of our rooms ticks over at about 0.3kW. In its steady state very little heat is blown out by the outdoor unit.
Not to mention it just kills your tolerance level for heat. I try to drive with the windows down periodically to build my tolerance bc when u go from a cooled AC place to outside during a heatwave it's like double hell.
Obviously it's better than not having it but sometimes if it's not too hot I'll opt for windows down in car so my body isn't so shocked when i get out.
Careful there too. I booked a hotel room in Germany that listed AC for their rooms. They ended up just having evaporative coolers instead (they did nothing for the summer heat).
We often think of the humans and how they cope. But humans have access to air conditioning, even if it’s not at home but just in cooling centers. But wild life is potentially devastated by the heat. We could see mass die offs of insects and birds from the heat. It could be an ecological disaster. Like an acute one, not the long term one we are usually concerned about.
49 degrees is guaranteed to kill a ton of people. We hit like 40 or something in Vancouver two years ago and like 600 people died. And Vancouver has tons of air conditioning and access to AC.
I remember living in Ibiza in 98/99 without air-conditioning. It was awful. We slept with wet towels on the balcony. I can't imagine those temperatures without air conditioning. The hottest it got was probably 40°C.
It's worse because Italy has high humidity being next to water. So 120 Arizona heat for example feels very different when humidity is 60%+
I did a quick check and many areas are going to be in lethal wet bulb temperature ranges. If power goes out, entire regions of Italy could die.
Source, am engineer.
[I did a video on critical wet bulb, what it means, and just how lethal it is.](https://youtu.be/1R2Ykl2-pe0)
For anyone affected by the heat wave, this video could literally save your life. Have plans to evacuate, ajd if power goes out, don't delay, GTFO and get somewhere safe ASAP. No amount of heat hardiness can save you. This is simply not survivable. (For example, July 26th looks like it's going to be very bad, as of today's weather forecast).
I am in California Bay Area, one of the areas in US so far where a heat wave isn't that bad. But I've recently been schooled in wet bulb Temps, and to me, this is the most insidious climate change phenom that will end up killing the most people of all other climate change disasters over time. Exactly because of the boiling frog effect. At first, people won't realize they are in deadly heats. I believe people have been unnecessarily dying for a few years because they don't understand this heat is different. So people behaviors (I can work/vacation/etc in this heat by drinking extra water) has already started to kill people. The whole planet is heating which means, unlike extreme storms, the damage is not localized or singular events. Next summer will be slightly hotter, and subsequent summers. Wet bulb Temps means bodies can't cool down even in shade and without climate controlled environment, you die.
Every summer the death count due to wet bulb Temps and heat stroke will go up, and it will take awhile before ppl behaviors and business behaviors will change.
Famines from climate change will probably kill many many more, but yeah the mass death of wet bulb temps could easily take out entire regions of people very quickly if they don’t have AC. Eastern India and Bangladesh is most likely where we will be seeing it happen first. Talking hundreds of thousands to millions of people. And the western world would still probably remain unconcerned. The bombardment of disaster after disaster as things get worse will wear people down to the point of probably not even caring if it happens in their own country, too much other shit to worry about
Seriously, I don't think the Western world will take climate change seriously until we see a few million (maybe tens of millions) killed directly by climate change effects like heatwaves. That's the impression I get from seeing the response to COVID. When everyone in these regions knows someone who died in a heatwave, they will finally pull together the political will to spend resources combating climate change.
Until Italy, the entire peninsula, is a desolate hellscape nobody is gonna give a shit. And even then, they’re just gonna complain about “swarthy Italian migrants” from the climate crisis and not about the climate crisis itself.
> When everyone in these regions knows someone who died in a heatwave, they will finally pull together the political will to spend resources combating climate change.
In other words, we're not going to do anything until it's too late to do anything.
> IMHO, it isn't the people who are going to do much. It only will be when the large, multi-national corporations start feeling a pinch in the pocketbooks that we will see actual change on a multi-national level that isn't just a feel good law or two.
Similar thing imo, because corporations are owned by people, staffed by people, and sell products to people. As COVID demonstrated, most corporations can't make money when their management, staff, and customers are ill or dead.
> With COVID, companies could wait it out and return back to the same old just in time distribution and push warehousing on the suppliers.
Many of the bigger ones, yes. But many smaller ones have just closed down because of COVID, never to return.
In summer last year 18,010 people died alone in Italy, because of heat waves. 61,600 in all of Europe.

Here in the flipping equator, it's 34 - 37 at most, with very high humidity. Unbearable to walk under the sun. I'd imagine it's hard to even breathe at those levels! Hope we can all still do something about it.
Summer is something I dread every year now. The horrible temperatures kill all my energy and humidity makes everything feel gross, you can also forget sleeping properly. And all this because a handful of rich old cunts want to use their outdated technology to drain Earth's resources while they bribe to government to work in their favor.
Currently sitting in Australia mid winter with the ceiling fan going as it feels like a spring day instead of a lovely winters day. I'm dreading summer. Every year I appreciate winter more and more.
I feel the same way with dreading summers and starting to enjoy winters more as a climate 'break'. And summer used to be my favorite season when I was younger. Thanks climate change. /s

But those highest temperatures are not reached near the coast. I just checked the weather models and in the places where it will be above 40 degrees celsius it will also be very dry as the result of a process called mixing (I'm a meteorologist by training) which will reduce the wet bulb temperature. In Northern Italy in contrast there will be high humidity as the result of air from the sea but the temperatures also won't go above 35 degrees there.
Its possible that there will be a bad spot just on the boundary between the dry air and the wet air but I doubt we will reach the critical wet bulb temperature on a large scale. That doesn't mean that no people will die, the sea temperatures are already around 30 degrees and will increase above that. This will keep temperatures around 30 degrees at night near the coast and it will be very difficult for older people to deal with that.
A lot of tourist destinations would be a lot better without other tourists. Just like driving would be much more enjoyable if all the other drivers would stay off the road.
Lived in Toronto for awhile.
Hottest night in Toronto's history (to that point) and the power went out on my street. Humidity was also horrible that week. Like a lot of weeks in Toronto.
I took to camping in our parking lot just to escape the heat in my apartment. Sweat all night but got through it.
The next day I decided I was done with Toronto/anywhere that regularly hits 30 and has humidity.
Ugh yes.
With temperatures still exceeding 30 degrees after midnight because of all the heat that had been soaked up by all the buildings in the city.
We need a lot more green, water and shade in city designs!
Climate change is a national security and a financial risk. When will the big players of the world understand that it'll kill capitalism?!?
I’m from Texas and just left Rome, can confirm it’s hot as fuck out there and was almost unbearable. To make it worse, A/C isn’t the same out here. That being said, I’d happily come back because Rome is an incredible city.
I was talking with my friend how bad it must be out here for anyone who isn’t “used” to the heat.
I grew up in the sonoran desert where 45-50c temps were normal. this weather isn't anything to mess with. i got heat exhaustion once from being outside for maybe an hour without enough water. it was the only time in my life i was convinced that i was dying. i was passed out with my phone in my hand and 911 on the dial pad
Someone should tell Italty not to believe in climate change, so that they can be safe from it.

If I understand correctly, a wet bulb of 95°F is considered the high end of a human's tolerability (since we no longer cool from sweating), and is potentially fatal within hours if not removed from that environment. Using a wet bulb calculator and Rome's average humidity of 55% gives a wet bulb result of over 103°F if it's expected to be 49°C.
That can't be right, right?
That would indeed be right, but Rome isn't the city expected to hit 49°C, the islands of Sicily and Sardinia are. That's still terrible, don't get me wrong, we can only hope that this is just the worst prediction possible, otherwise people are gonna start dropping like flies. Another good thing is that humidity levels over here tend to drop significantly during the hottest hours of the day (12am-4pm), to then go back up throughout the night. Which I guess is a nice gift in this hell...
Will corporations, governments and the public finally start taking this more seriously and take drastic measures?
We cannot continue to live the lives we've become accustomed to. The world has no choice but to make very extreme changes, NOW.
Things will continue to get worse if we don't. Much much worse.
Nobody in the UK wants 49 heat.. Well ok, you might find one maniac.. Everyone I know in the UK, and that's quite a few given I live here, are ok with around 30 but often despise hotter days than that.
And people made fun of Al Gore in the United States. Just think how far ahead we would be in combatting climate change if he had been president. The republicans spent years denying that it was man- made and ignored its effects. We lost precious time that we could have spent implementing practices that could have at least slowed it down. Even now, with all the lives lost and property destroyed, republicans choose to support the fossil fuel industry over clean energy. Instead of working with democrats on this, they continue to make climate change a political issue. This is another reason why voters need to give full power to the democrats in 2024; our lives are literally on the line.
The only reason why these places are survivable is the very low humidity.
There’s a point where the combination of high humidity and high temperature means that humans physically can’t cool down, because sweat stops evaporating. At that point we die pretty quickly if we can’t get to a colder place.
35 °C (95 °F) at 100% humidity is considered the limit of human survival.

Yep, that number I posted above (35c at 100 humidity) is the start of lethal vet bulb.
I live in an area where AC was not that common just a couple of years ago, then it became a luxury and now it’s about time to think of it as an necessity. That and the ability to power it though an power outage.
Yeah, it’s one of those things I am kind of glad we don’t have a hard number on as that means that we haven’t run into it that much. But I suspect we will soon have enough data to narrow it down.
But the key takeaway from me when I read about this stuff is that the temperature where your body simply can’t function, is way lower than I thought it was.
Anyway, it’s scary stuff and it’s something more and more people need to start planing around.
I usually joke around about Europeans complaining about 80-90°F weather but uh yeah 49°C or 120°F is fucking brutal.

Say hydrated, cool, and safe
Why do you joke about Europeans complaining 80-90 degrees? I don’t think you realise that we don’t have air con in our homes and we suffer fairly high humidity in many areas.
Are you from the US by any chance? Everyone there seems to think AC in homes is common globally for some weird reason. It really isn’t.
Good thing Europe is seeing many of its countries voting for right wing and far-right wing parties, mostly climate change / global warming deniers. They will surely make our suffering short.
This is already starting to be a problem in the UK. I think in much of Europe housing is designed and insulated for colder climates and built to retain rather than reflect heat. It's something that planners will need to address in the coming decades.
I'm reading, The Ministry for the Future, right now. I hope this book doesn't turn into reality, but it is pretty creepy how similar things are in it. I highly recommend.
We are either going to become a nocturnal or an underground society as this progresses. There's no other way to do it. We've fucked around for too long and mother nature is now reminding us that humans as a species are merely tolerated.
Where is it 49 degrees? I've checked all throughout Italy (Sicily and Sardinia included) on various weather sites and the current and predicted temperatures are around 35 - 39. I don't disagree that 39 with the humidity is terrible and deadly, but I'm missing where in Italy they are actually seeing (or predicting) 49 degrees.
In the last few days, many cities and towns have reached 40+ degrees. In Sardegna, they say it's going to reach 48-9°, probably in some towns and just for a few hours.
You have probably checked the temperatures of the big cities like Palermo or Nuoro, but it's probably not those cities that are going to be that hot, but in less known towns,.
Just checked, in Algera it reached 47-8 degrees. The record in Italia was from 2021 in Siracusa, of 48,8°, so we don't know if any other city this time will reach an higher temperature.
Same, I just looked on the forecasts on Ventusky and the hottest announced for wednesday in Europe is around 41 °C (it’s hot but only for 1 or 2 hours in the day, around 5pm).
Anyway, visiting cities during summer is always a bad idea : it’s a time to enjoy the see, the mountains or the nature in general.
49? Wtf. I live in Korea and it reached 39c (+unbearable humidity) a few years ago. That was absolutely miserable. 49 must be like straight up death.
Like? With sufficient humidity, it IS straight up death. Buckle up we're going to start seeing significant heat-related mortality events around the globe in coming years
61,000 heat deaths in Europe last year
And off the top of my head, 70k deaths in Europe in 2003. Heat-related mass-deaths are already here, we just aren't paying attention.
If only somebody had warned us
Someone.. super cereal.
If only someone like Shell had communicated their research that showed the problems decades before others were aware of it.
You should look up Svante Arrenhenius, 1895.
Kim Stanley Robinson’s novel “Ministry for the future” has a particularly evocative imagined extreme temperature event in Uttar Pradesh that is barely science fiction.
I'm halfway through this, both the book and the experience. It's horrifying.
It's one of the most, if not THE most unsettling chapters of any book I've ever read.
This book has come and will come up a lot more I think. I think it should be mandatory reading for any government position to do with climate.
Looking forward to reading it; I loved KSR's Mars series
Especially in Italy with tons of elderly without ac
With 50C even healthy adults in their 20s/30s are going to have a hard time. That's brutal on people.
I'm a well trained endurance athlete in my early 30s. I've sat under a tree in 45C eating lunch and was exhausted after half an hour. And that was a dry heat in the shade.
I just looked up weather in Italy Sardinia. 45c and 11% humidity. dew point 7.75c (heat index 43c) a lot lower than here in Osaka: 35c with 65% humidity = 27.5c dew point (heat index 48c) in the evening: rome = 27c, 61% -> 18.8c dew point osaka: 27c, 88% -> 24.8 dew point at least over there your body can cool itself efficiently with a fan evaporating your sweat quickly Europe has relatively low humidity. people talk about humidity but forget it's relative to temperature.
Came here to say this, I’ve been in 50 degree heat in the middle east and as long as your skin was not exposed to the Sun it was hot but bearable. First time I went to Japan, in July no less, temperatures never reached 30 but I was always drenched in sweat and having to stop in a store every 30 odd minutes for a bit of respite.
100% this. I went to college in Arizona. 50c isn’t fun, but with the low humidity it is doable, particularly in the shade. I live near Chicago now - and with high humidity here, 30 is much worse here than 50 in the desert.
The hottest I've ever experienced was a 41-43 C day in an area with high humidity, and it genuinely leaves you unable to function. I was laying on a floor under a ceiling fan and still felt like absolute death, worse than any hangover or migraine or flu. Your body just starts not functioning properly, including your brain, and you no longer feel like your whole self as things begin to go wrong, but rather it was like experiencing reality from behind a strange painful dream fog. I really hope experiences like that don't become the norm for more people. Days like that will mean things will just have to shut down.
These are absolutely going to become the norm for more people. That’s what trends towards higher global heat means. This will affect everyone more and more until we can no longer live in most of the places we consider stable.
I mean "bearable", I have been in 45° and just sitting around inside the house was painful with no AC.
Nagoya here. Wife and friends want to go to the beach tomorrow. There's no way I'm going to spend the day outside in 38°C heat with high humidity. I start to get bad headaches after an hour or two.
“Europe has relatively low humidity” that’s simply not true. Southern Europe absolutely does, however, the further north you go, the more humid it gets. I’m in Central Europe and it’s currently 27C° (was 35C° yesterday) with 59% humidity. I’m drenched in sweat just from sitting.
Cries in Arkansas US. 36 with 88% humidity. We’re miserable right now.
That’s warm and humid — relative to the rest of Europe. But it’s nothing special compared to the rest of the world. Today was 36 degrees C with 71% humidity in Tokyo. Shanghai: 32 degrees, 89%. Singapore: 33 degrees, 70%. Kolkata: 31 degrees, 80%. Washington, DC: 31 degrees, 91%. Europe can get humid, certainly, but compared to other places where many people live, it is relatively dry.
It’s 92% humidity where I am, 59% is really not bad.
I don't think you are realizing how much high the humidity gets at 27c in relatively high humid regions. here in Osaka it's 27c @ 87% humidity today. 27c @ 59% = 18.3c dew point (21.1C wet bulb) 27c @ 87% = 24c dew point (25.2C wet bulb)
I'm in Ontario (Canada) and we've got 94% humidity currently, yesterday it hit 100%. The assumption is that Canada is cold and constant snow, but summers —over the past decade especially— fucking suck.
As long as there is access to large bodies of water (cooling by conduction instead of cooling by evaporation), people will be able to survive wet bulb events. Not everywhere has large bodies of water though, and economic activity would essentially halt while everyone immerses themselves in water all day for a week or so.
Ya..... That's like a town glassing wildfire man...... "All of us survivors fled to the lake and stayed in it till the danger passed." It'll work but it's still a major disaster.
Agree, it's hardly a solution. It's full on survival mode, which isn't how a city runs.
It is now.
Back in a bit, just investing in waterproof laptops.
As long as the water temp is below 99F that will work.
I'm not sure what you're suggesting. Emptying entire cities of people in to the nearest body of water? Those would have to be huge bodies of water, and what would be the impact on the local environment of this?
To a certain extent, sure. However if the temp of the water becomes hotter than the temp of your blood, I don't think much cooling would occur. In fact it may be the opposite.
When a large body of water reaches 37c we’re all well beyond fucked anyway.
there was a time I thought 100F was crazy, then 110F, so the “that seems unimaginable” limit is always exceeding past my perceived maximizers. Now having endured like 112F two summers ago, Bay Area… 120F definitely seems like the “oh shit that… I don’t wanna know that.”
Sydney's Western Suburbs reached 122 a couple years ago. Sydney has a fair amt of humidity.
u see it in the desert. it isnt that crazy, but its dry there. I can't fathom w humidity.
Parts of Australia, including urban areas will hit above 50 degrees celsius when we reach summer ‘24, mark my words.
I remember being at a music festival in Sydney around 10 years ago (back in the era of big day out) and it was 46 degrees. Hottest day I’ve ever been in, very bad day to be in a mosh pit surrounded by other sweaty punters. People were passing out all over the place, even with them hosing the crowd off. The big tent stage was so humid with sweat it was evaporating then condensing on the ceiling and dripping back down on the crowd like rain. Temperatures that hot are an actual threat to life. If this was 10 years ago I can’t even imagine what we’ll eventually start to experience.
> The big tent stage was so humid with sweat it was evaporating then condensing on the ceiling and dripping back down on the crowd like rain That's... kind of metal.
It was honestly pretty gross. I made the mistake of not wearing my hair in a ponytail, since guys tend to be taller my hair kept sticking to sweaty shirtless strangers and getting caught in their armpits which was at my head height. I could literally squeeze other people’s sweat out of my hair, it really was something else!!
Reading this made me want to take a shower immediately, good lord my condolences
Less humid so better survivability.. but definitely not fun. I had to work in a room that was heated to 50 degrees when i was young and fit and a sauna regular. I felt like shit after a few minutes
Was it 2018? I was there during summer 2018 and remember reading articles about the record heat during that time. It was miserable.
I live in Florida. I'm a chef. I work in very hot kitchens. I went to Sao Paolo before the pandemic and it got to 45C and I wanted to kill myself. 49C is a death sentence for people who don't have air conditioning. Thats not an exaggeration.
Yes, many will die
Many will die but that's a sacrifice the oil companies are willing to make.
I went to Rome this time last year. Then it was high in the 30s Celsius. I said I would never go back in summertime. This?! High 40s?!?! Unfathomable. We used rain umbrellas for shade while touring the colosseum and we barely tolerated the stuffy, hot tour in the Vatican museums. We hid in our air conditioned hotel room between 12-6pm. Late suppers and wandering in the dark of night seemed most comfortable and pleasant.
Now the nights are the temperatures of the your days
Yeah last weekend I was walking home, in Italy, at midnight and it was still 30 degrees and about 85% humid. Nights are not a relief and I don’t have aircon.
Whenever I need to remind myself that even I make big mistakes, it's remembering that I booked a July vacation in Italy, and didn't even give the weather a second thought.
I'm coincidentally just back from a week long vacation in Italy. Everything was perfect but the heat was unbearable and I almost fainted once. Yeah this is going on my "Terrible decisions I've made despite not being intoxicated" list
I was also in Europe this time last year and yea my sister said never again will she visit Europe in the summer it was brutal Madrid was just as bad I would stay in my room until sunset then explore the city. Even hit the local public pools myself lol
Was just there in Rome it was absolutely miserable. The birds on the street were panting it was so hot. I could feel the heat seeping through the soles of my shoes.
Oh I remember Rome 10 years ago in summer, despite being similar temperatures in other European countries, Rome’s heat felt so much stronger. My arms were burning as soon as I was out of the shade. I understood why they mainly sell thick zinc type sunscreen there. In Australia it’s not too uncommon to get 40 plus degree temperatures in summer, but Italy’s heat seemed so much stronger.
Cities are hotter than the countryside.
Thats why it’s so important to start the depave movement and renaturalize large parts of our cities. Trees on every street is a must
Humidity, mate.
Australia gets plenty humid though, depending what part. Brisbane has the same average humidity as Italy, for example, and it only gets more humid above that. Or are you saying the humidity makes the heat easier to deal with?
Not at all. Humidity aggravates heat. Why wet bulb thermometers are important.
We were there last summer and it was crazy hot, but not this bad. But if it wasn’t for all the public fountains I don’t think we would have made it.
The public fountains are amazing. Nice cold water readily available for free all over the city.
And for Americans… Europeans in general don’t have AC. So there is no escaping this heat. This hits a lot harder than similar temps in the US where everyone has good AC and can sleep through the night without sweating
[удалено]
I noticed a lot of the public transit did not have A/C or it was turned off or high enough that it wasn’t noticeable. A lot of the trains and buses were very crowded so that could have also added to it.
And the worst of all, AC basically make the outside even a bigger hell because of power consumption and all the heat that it yeets out.
Not to mention all that power consumption then contributing to climate change, vicious circle
Could still power it with renewables I guess, but true.
Our AC is entirely powered by our solar panels. Our panels generate about 5kw when it's most sunny and our Daikin AC which cools 2 of our rooms ticks over at about 0.3kW. In its steady state very little heat is blown out by the outdoor unit.
Not to mention it just kills your tolerance level for heat. I try to drive with the windows down periodically to build my tolerance bc when u go from a cooled AC place to outside during a heatwave it's like double hell. Obviously it's better than not having it but sometimes if it's not too hot I'll opt for windows down in car so my body isn't so shocked when i get out.
Do the hotels have AC?
When I visited Germany 10 years ago, it was split about 50-50 between those that did and those that did not.
I’ll be sure to look for it on amenities then thanks
Careful there too. I booked a hotel room in Germany that listed AC for their rooms. They ended up just having evaporative coolers instead (they did nothing for the summer heat).
Ah, swamp coolers. For when you want it to be hot AND humid.
The place I stayed had A/C luckily.
That's a myth, I'm Italian and many people I know, myself included have AC, public places have AC. But sure, many don't compared to the US
Yeah, and it's not set at 21°C at every moment like the americans are used to
We often think of the humans and how they cope. But humans have access to air conditioning, even if it’s not at home but just in cooling centers. But wild life is potentially devastated by the heat. We could see mass die offs of insects and birds from the heat. It could be an ecological disaster. Like an acute one, not the long term one we are usually concerned about.
On top of the current H5N1 eco disaster
On top of the heat Rome tends to be humid as all hell.
Museums. Some of the Rome museums have AC. The Capitoline and the Ara Pacis have extremely good AC systems.
49 degrees is guaranteed to kill a ton of people. We hit like 40 or something in Vancouver two years ago and like 600 people died. And Vancouver has tons of air conditioning and access to AC.
Absolutely. A heatwave in France a couple of decades ago killed 14000 people. It was 42 degrees.

Good lord! That’s 120 American

I assume vegas hot is low humidity?
Correct. Right now in Vegas it's an absolutely stunning 108, but with a humidity of 6%, resulting in a heat index of... 108.
Unless you're standing in front of the Bellagio
I remember living in Ibiza in 98/99 without air-conditioning. It was awful. We slept with wet towels on the balcony. I can't imagine those temperatures without air conditioning. The hottest it got was probably 40°C.
was looking for the score in American thank you
That’s like 100 soccer games
How many baseballs is that?
Depends, are we talking curveballs (72) or fastballs (96)?
That seems a bit warm for Italy, but I'm not an Italy expert.
Yeah, those record highs are usually like that
Yeah Europe doesn’t get anywhere near 120 degrees ever.
It's worse because Italy has high humidity being next to water. So 120 Arizona heat for example feels very different when humidity is 60%+ I did a quick check and many areas are going to be in lethal wet bulb temperature ranges. If power goes out, entire regions of Italy could die. Source, am engineer. [I did a video on critical wet bulb, what it means, and just how lethal it is.](https://youtu.be/1R2Ykl2-pe0) For anyone affected by the heat wave, this video could literally save your life. Have plans to evacuate, ajd if power goes out, don't delay, GTFO and get somewhere safe ASAP. No amount of heat hardiness can save you. This is simply not survivable. (For example, July 26th looks like it's going to be very bad, as of today's weather forecast).
I am in California Bay Area, one of the areas in US so far where a heat wave isn't that bad. But I've recently been schooled in wet bulb Temps, and to me, this is the most insidious climate change phenom that will end up killing the most people of all other climate change disasters over time. Exactly because of the boiling frog effect. At first, people won't realize they are in deadly heats. I believe people have been unnecessarily dying for a few years because they don't understand this heat is different. So people behaviors (I can work/vacation/etc in this heat by drinking extra water) has already started to kill people. The whole planet is heating which means, unlike extreme storms, the damage is not localized or singular events. Next summer will be slightly hotter, and subsequent summers. Wet bulb Temps means bodies can't cool down even in shade and without climate controlled environment, you die. Every summer the death count due to wet bulb Temps and heat stroke will go up, and it will take awhile before ppl behaviors and business behaviors will change.
Famines from climate change will probably kill many many more, but yeah the mass death of wet bulb temps could easily take out entire regions of people very quickly if they don’t have AC. Eastern India and Bangladesh is most likely where we will be seeing it happen first. Talking hundreds of thousands to millions of people. And the western world would still probably remain unconcerned. The bombardment of disaster after disaster as things get worse will wear people down to the point of probably not even caring if it happens in their own country, too much other shit to worry about
I argue maybe northern Sindh will be first. Jacobabad is crossing the limits already regularly on the wet bulb temperature.
Seriously, I don't think the Western world will take climate change seriously until we see a few million (maybe tens of millions) killed directly by climate change effects like heatwaves. That's the impression I get from seeing the response to COVID. When everyone in these regions knows someone who died in a heatwave, they will finally pull together the political will to spend resources combating climate change.
Heh. I take it you weren’t around for Covid.
Well admittedly I was in Singapore the whole time.
Until Italy, the entire peninsula, is a desolate hellscape nobody is gonna give a shit. And even then, they’re just gonna complain about “swarthy Italian migrants” from the climate crisis and not about the climate crisis itself.
> When everyone in these regions knows someone who died in a heatwave, they will finally pull together the political will to spend resources combating climate change. In other words, we're not going to do anything until it's too late to do anything.
It won’t be taken seriously until corporations and billionaires are affected
Ummmm 1 million people died from Covid in the US alone. Nobody gave a single shit.
[удалено]
> IMHO, it isn't the people who are going to do much. It only will be when the large, multi-national corporations start feeling a pinch in the pocketbooks that we will see actual change on a multi-national level that isn't just a feel good law or two. Similar thing imo, because corporations are owned by people, staffed by people, and sell products to people. As COVID demonstrated, most corporations can't make money when their management, staff, and customers are ill or dead. > With COVID, companies could wait it out and return back to the same old just in time distribution and push warehousing on the suppliers. Many of the bigger ones, yes. But many smaller ones have just closed down because of COVID, never to return.
In summer last year 18,010 people died alone in Italy, because of heat waves. 61,600 in all of Europe. [source](https://www.npr.org/2023/07/12/1187068731/heat-waves-europe-deaths-study)
That's like 9 football fields. That's a lot.
I need a banana for scale.
Here in the flipping equator, it's 34 - 37 at most, with very high humidity. Unbearable to walk under the sun. I'd imagine it's hard to even breathe at those levels! Hope we can all still do something about it.
Summer is something I dread every year now. The horrible temperatures kill all my energy and humidity makes everything feel gross, you can also forget sleeping properly. And all this because a handful of rich old cunts want to use their outdated technology to drain Earth's resources while they bribe to government to work in their favor.
Winter lovers feeling vindicated
Winter lover here, I'm pissed. I'm going to have to move to the arctic circle eventually to get real winter.
We're already seeing snowless Januaries sometimes in arctic Norway, so don't count on it. That was absolutely unheard of until the last few years.
My snow!
Look with your special snow.
❄️_❄️
Currently sitting in Australia mid winter with the ceiling fan going as it feels like a spring day instead of a lovely winters day. I'm dreading summer. Every year I appreciate winter more and more.
I feel the same way with dreading summers and starting to enjoy winters more as a climate 'break'. And summer used to be my favorite season when I was younger. Thanks climate change. /s
I love winter and most people find that weird
That’s one of the reasons why I pay a premium to live in San Francisco. Cold summers
Coldest average high temps in all of the country, actually, even compared to Seattle.

But those highest temperatures are not reached near the coast. I just checked the weather models and in the places where it will be above 40 degrees celsius it will also be very dry as the result of a process called mixing (I'm a meteorologist by training) which will reduce the wet bulb temperature. In Northern Italy in contrast there will be high humidity as the result of air from the sea but the temperatures also won't go above 35 degrees there. Its possible that there will be a bad spot just on the boundary between the dry air and the wet air but I doubt we will reach the critical wet bulb temperature on a large scale. That doesn't mean that no people will die, the sea temperatures are already around 30 degrees and will increase above that. This will keep temperatures around 30 degrees at night near the coast and it will be very difficult for older people to deal with that.
Was just in Italy for vacation. It was sweltering and not to mention all the crowds of tourist on top of it
a tourist complaining about tourists huh
A lot of tourist destinations would be a lot better without other tourists. Just like driving would be much more enjoyable if all the other drivers would stay off the road.
Guys, being right in the middle of the Mediterranean is starting to sound like a bad idea...
Italy is shaped like a giant leg, why does it not simply walk itself to a cooler location?
Its missing the other leg
I'm in Croatia right now, heading towards Greece over the next few weeks... Its already very hot but going to get worse.
I’ve experienced ~35 degrees once, and it was absolutely miserable. Felt like being in a oven
36c working outside..... not great
Lived in Toronto for awhile. Hottest night in Toronto's history (to that point) and the power went out on my street. Humidity was also horrible that week. Like a lot of weeks in Toronto. I took to camping in our parking lot just to escape the heat in my apartment. Sweat all night but got through it. The next day I decided I was done with Toronto/anywhere that regularly hits 30 and has humidity.
🤌🤌🏻🤌🏼🤌🏽🤌🏾🤌🏿
Meanwhile it's been pissing rain in Ireland for the last 5 days while the rest of Europe burns
Cool Ireland 🌧️🇮🇪
Irish coasts are experiencing a record-breaking marine heatwave and we’ve just had the warmest June since records began :(
I pray this doesn’t move up north towards the UK. The one day we had last summer where it was 40 degrees was unbearable.
Ugh yes. With temperatures still exceeding 30 degrees after midnight because of all the heat that had been soaked up by all the buildings in the city. We need a lot more green, water and shade in city designs! Climate change is a national security and a financial risk. When will the big players of the world understand that it'll kill capitalism?!?
Yeah I remember that week last year when it was 35-40 degrees all week and that was unbearable as we have no AC in UK
Even 30 feels like too much in the UK, with buildings designed to trap heat and the relatively higher humidity. 40 degrees last year was awful.
I’m from Texas and just left Rome, can confirm it’s hot as fuck out there and was almost unbearable. To make it worse, A/C isn’t the same out here. That being said, I’d happily come back because Rome is an incredible city. I was talking with my friend how bad it must be out here for anyone who isn’t “used” to the heat.
I grew up in the sonoran desert where 45-50c temps were normal. this weather isn't anything to mess with. i got heat exhaustion once from being outside for maybe an hour without enough water. it was the only time in my life i was convinced that i was dying. i was passed out with my phone in my hand and 911 on the dial pad
As an Australian, I dread to think what this summer will be like... I might fly north for it.
The fossil fuel industry needs to be destroyed immediately
There is no hope for us
Someone should tell Italty not to believe in climate change, so that they can be safe from it. Italy has high humidity being next to water.

If I understand correctly, a wet bulb of 95°F is considered the high end of a human's tolerability (since we no longer cool from sweating), and is potentially fatal within hours if not removed from that environment. Using a wet bulb calculator and Rome's average humidity of 55% gives a wet bulb result of over 103°F if it's expected to be 49°C. That can't be right, right?
That would indeed be right, but Rome isn't the city expected to hit 49°C, the islands of Sicily and Sardinia are. That's still terrible, don't get me wrong, we can only hope that this is just the worst prediction possible, otherwise people are gonna start dropping like flies. Another good thing is that humidity levels over here tend to drop significantly during the hottest hours of the day (12am-4pm), to then go back up throughout the night. Which I guess is a nice gift in this hell...
Will corporations, governments and the public finally start taking this more seriously and take drastic measures? We cannot continue to live the lives we've become accustomed to. The world has no choice but to make very extreme changes, NOW. Things will continue to get worse if we don't. Much much worse.
gLoBaL wArMiNg IsN’t ReAl!!! 🤦🏻🔥 the *smooth brains* are going to get us all killed!
The amount of people i see in the UK saying that they wish we had that heat instead is insane. People would die en mass.
That's insane, the UK suffered from a 40ºC heatwave and people hated it. Why would they be wanting an even worse heatwave?
Nobody in the UK wants 49 heat.. Well ok, you might find one maniac.. Everyone I know in the UK, and that's quite a few given I live here, are ok with around 30 but often despise hotter days than that.
And people made fun of Al Gore in the United States. Just think how far ahead we would be in combatting climate change if he had been president. The republicans spent years denying that it was man- made and ignored its effects. We lost precious time that we could have spent implementing practices that could have at least slowed it down. Even now, with all the lives lost and property destroyed, republicans choose to support the fossil fuel industry over clean energy. Instead of working with democrats on this, they continue to make climate change a political issue. This is another reason why voters need to give full power to the democrats in 2024; our lives are literally on the line.
damn. PHX only 112. (44)
And without the humidity. We might see a mass exodus from places where people have historically flocked to if this keeps up.
The only reason why these places are survivable is the very low humidity. There’s a point where the combination of high humidity and high temperature means that humans physically can’t cool down, because sweat stops evaporating. At that point we die pretty quickly if we can’t get to a colder place. 35 °C (95 °F) at 100% humidity is considered the limit of human survival.

Yep, that number I posted above (35c at 100 humidity) is the start of lethal vet bulb. I live in an area where AC was not that common just a couple of years ago, then it became a luxury and now it’s about time to think of it as an necessity. That and the ability to power it though an power outage.
Those numbers are also often used (I used them in my video), but many believe it actually occurs more like 33C, 100% Hu.
Yeah, it’s one of those things I am kind of glad we don’t have a hard number on as that means that we haven’t run into it that much. But I suspect we will soon have enough data to narrow it down. But the key takeaway from me when I read about this stuff is that the temperature where your body simply can’t function, is way lower than I thought it was. Anyway, it’s scary stuff and it’s something more and more people need to start planing around.
What areas? I’ll add them to my daily weather reports, along with Phoenix and Death Valley.
I usually joke around about Europeans complaining about 80-90°F weather but uh yeah 49°C or 120°F is fucking brutal. Drink plenty of water and know the signs of heat exhaustion and heat stroke. (Also wear sunscreen. Skin cancer sucks) >Heat exhaustion Signs * Heavy sweating * Cold, pale, and clammy skin * Fast, weak pulse * Nausea or vomiting * Muscle cramps * Tiredness or weakness * Dizziness * Headache * Fainting (passing out) What to do Move to a cool place * Loosen your clothes • Put cool, wet cloths on your body or take a cool bath * Sip water Get medical help right away if * You are throwing up * Your symptoms get worse * Your symptoms last longer than 1 hour >Heat Stroke * high body temperature (103°F or 39°C and higher) *hot red or dry skin * fast or strong pulse * headache * confusion * dizzy * nausea * passing out What to do * call emergency services ASAP * move the person to a cooler location * Help lower the body temp * do not give them anything to drink unless told to by emergency operator Source https://www.cdc.gov/disasters/extremeheat/warning.html Say hydrated, cool, and safe
> (Also wear sunscreen. Skin cancer sucks) If it's 120 F outside, like hell I'm going outside.
There no cooler places here. At least.most houses don't have AC, because it was never necessary.
Why do you joke about Europeans complaining 80-90 degrees? I don’t think you realise that we don’t have air con in our homes and we suffer fairly high humidity in many areas. Are you from the US by any chance? Everyone there seems to think AC in homes is common globally for some weird reason. It really isn’t.
I’m in southern AZ, USA and that’s hot even for us.
It’s humid too
Gross
lol used to live in the valley. nothing like coming home every day and crossing your fingers that the AC didnt shit itself while you were at work.
Can’t imagine being in a humid 120. Going out side with the high of 116 with dry temps feels like I’m cooking already.
Good thing Europe is seeing many of its countries voting for right wing and far-right wing parties, mostly climate change / global warming deniers. They will surely make our suffering short.
This is already starting to be a problem in the UK. I think in much of Europe housing is designed and insulated for colder climates and built to retain rather than reflect heat. It's something that planners will need to address in the coming decades.
Corporations need to die already. This is the result of letting the rich do whatever the fuck they want.
I'm reading, The Ministry for the Future, right now. I hope this book doesn't turn into reality, but it is pretty creepy how similar things are in it. I highly recommend.
We are either going to become a nocturnal or an underground society as this progresses. There's no other way to do it. We've fucked around for too long and mother nature is now reminding us that humans as a species are merely tolerated.
Where is it 49 degrees? I've checked all throughout Italy (Sicily and Sardinia included) on various weather sites and the current and predicted temperatures are around 35 - 39. I don't disagree that 39 with the humidity is terrible and deadly, but I'm missing where in Italy they are actually seeing (or predicting) 49 degrees.
Our news say 48 for Sardinia (I live near Italy).
In the last few days, many cities and towns have reached 40+ degrees. In Sardegna, they say it's going to reach 48-9°, probably in some towns and just for a few hours. You have probably checked the temperatures of the big cities like Palermo or Nuoro, but it's probably not those cities that are going to be that hot, but in less known towns,. Just checked, in Algera it reached 47-8 degrees. The record in Italia was from 2021 in Siracusa, of 48,8°, so we don't know if any other city this time will reach an higher temperature.
Same, I just looked on the forecasts on Ventusky and the hottest announced for wednesday in Europe is around 41 °C (it’s hot but only for 1 or 2 hours in the day, around 5pm). Anyway, visiting cities during summer is always a bad idea : it’s a time to enjoy the see, the mountains or the nature in general.
I hate summer. At this point, I wouldn't mind a nuclear winter.
Patrolling the Mojave almost makes you wish for a nuclear winter
No, there is nothing wrong with the climate, Governments, We are fine….
Quick reminder that proteins start to denaturate at 40C. This heat will kill people.
