Get your in comments disregarding predictions coming true before this weather related story gets flagged off the front page.

Well, maybe there is so little call to action in this one that it’ll stick around?

Why do you think this will be flagged? I hardly ever see comments disregarding climate change here.
There was anoter bbc article about the need for political action, that managed to stay up for about 2 hours, getting plenty of “well, we don’t need to worry about it now, the market will sort it” comments before being flagged off.
Lots of climate stories get flagged off the front page, and rapidly. Or trigger HN spam flags from the succession of low karma deniers with "climate has always been changing", "well we don't have accurate temperature records back to the yyy age" zero substance comments. If Europe is wider awake they seem to have more chance of sticking around a while...

Which is a bit sad as it's one of the few places online I'd have hoped for a more engaging and productive discussion of the topic.

It's one of the most-discussed topics on HN.

Everyone's favorite topic feels under-discussed because frontpage space is the scarcest resource here. Probably even Rust hackers feel that way.

Sure, there's a decent number that do survive, but there's also a lot that attract interest, decent discussion then bomb fast from either getting flagged or excess downvotes/comments - however your algo decides to derank.

Which is not to say I expect them all to stick... :)

How can you have a productive discussion when you immediately dismiss anyone who questions things as "low karma deniers"? Any meaningful discussion should start with addressing: "climate has always been changing", "well we don't have accurate temperature records back to the yyy age" since they're very relevant points.

Except they're not relevant. I could understand someone in the 1980s and 1990s raising those in good faith, through poor understanding, before high general awareness. Just as I could understand someone raising points around fatty food and obesity in the same era. At least climate, unlike fat in food, hasn't had an entire irrelevant and possibly harmful industry spring up based on that FUD.

Today, it isn't meaningful, it's just a distraction tactic to dilute and spread doubt. The most charitable interpretation of someone raising such points as today is they have got their terrible "understanding" from the most biased, disingenuous sources created and promoted by those with an agenda.

https://www.theguardian.com/environment/climate-consensus-97...

I mean they’re common sense no? If they are so obviously false or irrelevant then maybe you could address them. Calling people who come at this rationally “disingenuous” does nothing to further your argument.

Every time an article headline states "Hottest Temperature Ever!" I just round file it. The earth was a molten ball of lava at some point, it's obviously hyperbole meant to prey on people's fears. What they maybe mean is "Hottest Temperature In The 100 Years We've Been Keeping Accurate Records". That's an article I would read.

Humans have lived through multiple ice ages. The climate changes; regularly and drastically. Humans have always survived and I'm sure we'll continue to survive.

I don't see anyone fretting about building an anti-asteroid system or talking about super volcanoes (both of which pose a much larger existential threat to humanity). I don't know how old you are, but for my entire life (and for a long time before that) people have been saying that the world is going to end for one reason or another. At some point you learn the signs of hype and just tune them out. Dishonest headlines and arguments are the #1 sign.

I called the source disingenuous, not the person reading it. The "science" produced to an agenda and budget from Exxon or some thinktank who are also oil or politically funded - yet claim independence by lies and obfuscation. I hope at some point soon it's made illegal with heavy sentence - regardless of political or financial stance - or requires clear enough disclosure of interests they cannot weasel out of.

If you round file some temperature headline that doesn't extend with precision the frame of reference, well that surely means you read no mainstream media on any topic as it encompasses them all - politics, sport, tech, climate, international relations, crime. Everything. I credit you, and most readers, with enough intelligence to know "hottest temperature ever" implies hottest temperature on record not hottest temperature since creation or some arbitrary historic era. They can do it with politics and business easily enough.

I'm in my late fifties - climate is the first existential threat that has the credibility of scientific support, and repeated evidence from numerous indicators that are coming at accelerated rate. It's been undertood in varying degree and known for years. Cold War was never that. In fact for most people, most of the time, Bay of Pigs and missile crisis excluded, it was a complete non-event. Previous mis-reported headlines of some scientific finding or discovering cold fusion were never that. Media is bad at science, water is wet, news at 11. Asteroids and super-volcanoes? First let's quantify the risk - that right now seems vanishingly small. Climate is unrecognisable compared to my childhood and twenties, or my parents and grandparents descriptions of their youth in the early 20th C. Species and habitat loss is having weekly consequences. TL;DR it's the first credible existential threat in my entire life or in any of the periods of history I've read.

Meanwhile in Greece it has been the coolest summer of the last 20 years at least. We didn't have a single heatwave so far. It even rained in mid July.
"Coolest"? It just hasn't hit 40 yet. The weather has been crazy, we had a goddamn tornado for crying out loud. It even rained in July!
Cool as in opposite of hot. Not cool like nice.
Records tumble.

That's a once off message - being a record. Good for immediate PR. Terrible for sending the message that needs to be sent - namely climate change.

The messaging needs to switch towards things are now permanently hot in X rather than well today is extra hot.

The northern half of europe (anywhere north of the mediteranean) really sucks at handling heat. In most of France, Belgium or Germany it's impossible to find apartments with ceiling fans or air conditioning.

There's also no concept of central air conditioning anywhere in europe for non-commercial buildings, which is a big opportunity for improvement (especially in Greece where air conditioning is everywhere, looks disgusting in the streets and is less efficient than a central unit in summer).

Possibly the worst offence in Germany and especially in Belgium is that you can't ask restaurants/bars for tap water. They'll refuse to serve you, and will ask you to buy bottled water. (Tap water is 100% safe, they just don't want to do the kindness)

It's an especially absurd custom given that, you go west a few kilometers and pass the French frontier, every bar and restaurant is legally obligated to serve tap water for free whenever customers ask. In most mediterranean countries, it's not even a question of asking: You sit down, a waiter will bring you water, before you've even ordered.

I think the Greek custom of AC units everywhere is because traditionally houses have been pretty cool, so there hasn't been much of a need for central AC until now. We prefer to open our windows at night and shut them during the day, and we use fabric awnings to keep the sun out. Plus, most buildings are rather old so HVAC systems weren't popular.

That said, yeah, it does look very ugly, and I wish new buildings had central AC units.

It's like that in parts of the U.S. as well - the vast majority of Bay Area homes do not have central A/C or even a room air conditioning unit, because for 99% of the year, you don't need one. This is getting to be a problem with 100 degree days becoming more common.

Strangely, I saw more units with central A/C in Toronto than in San Francisco. I guess they're used to hot summers there.

(It's ubiquitous in the American South, though, since many of those areas were quite unpleasant to live in before air conditioning was invented.)

>Strangely, I saw more units with central A/C in Toronto than in San Francisco. I guess they're used to hot summers there.

A home in San Francisco doesn't need central heating at all, but a home in Toronto (where it remains frozen for a few months in the year) very much does.

Once you have central heating, adding a central A/C unit (or a heat pump) is not a significant additional expense compared to how much a home usually costs, and failing that can be roughed in for later installation, so the decision to purchase one when the summers get too hot is an easy one, or when you have a family and want A/C so that small children or the elderly don't roast while living/visiting.

> Strangely, I saw more units with central A/C in Toronto than in San Francisco. I guess they're used to hot summers there.

Toronto can get humid at times:

* https://en.wikipedia.org/wiki/Toronto#Climate

* https://en.wikipedia.org/wiki/Humid_continental_climate#Hot_...

Temperatures in July and August often go >30C, and adding >70% humidity to get the Humidex you're looking at ("feels like") >40C.

* https://en.wikipedia.org/wiki/Humidex

* https://toronto.weatherstats.ca/metrics/relative_humidity.ht...

Sweating starts become ineffective because the air is already saturated with moisture, the sweat just beads up on your skin and there's no evaporative cooling. If you have a "dry heat", what you mostly have to do is (a) be in a draft to cool down and (b) replenish liquids. With >80% humidity, it's like trying walk in and breathe soup.

Yeah agreed regarding tap water. Most of the time a bottle of water is much more expensive than a beer or soda as well.

> In most of France, Belgium or Germany it's impossible to find apartments with ceiling fans or air conditioning.

My girlfriend's grandparents are still in france and the 108 degrees fahrenheit temperature that it is supposed to be tomorrow sounds miserable. The grandparent says that people are looked down upon for having AC so they had to buy the grandparent a fan but that doesn't help when it gets above the 98.6 degree body temperature.

We got a lot of problems here in the US, but I love that I can get tap ice water from every restaurant for free and I've even gotten free ice water from starbucks without buying anything. So nice.

I never got why people are so into free tap water everywhere. Who goes into a restaurant, does not order anything, and asks for free ice water?

If I'm a restaurant owner and someone is taking up a seat while drinking free tap water, of course I'm not going to like that.

"Taking up a seat without ordering" is frowned upon. It's okay to dislike that as a restaurant owner. It's universally disliked, and barring exceptional circumstances, it's not a cool thing to do.

That is what the problematic behaviour with your described case is. "Free tap water", however, absolutely should be the standard. In Belgium, you will generally be refused tap water even if you're a paying customer with a 100 EUR bill. Whereas in France, it's illegal to refuse serving tap water… think about that.

If you're not allowed to drink tap water, you'll be drinking bottled water which creates plastic/glass waste and promotes a business that essentially repackages tap water.

I'm Belgian so I'm aware we don't really drink tap water. However, to say that tap water tastes exactly the same as bottled water is also a bit ridiculous in my mind.

At the end of the day I guess it comes down to preference. Perhaps a silly question, but why do you go for tap water? Just because of the waste issue? And a second question, why would tap water have to be free and would you pay for it?

PS: Cool business! Are you in Belgium?

> why do you go for tap water?

It's wasteful not to. I wouldn't say it tastes the same, but even though the water where I live is very chalky, I'm personally fine with it.

> why would tap water have to be free

Because it's virtually free to the restaurant. Having it free also promotes the healthy habit of drinking water instead of other drinks: When thirsty, if tap water is not an option, many people will choose soda over water… if you're paying for it anyway.

> would you pay for it?

If it's water I want, I'd rather pay for tap water than pay for bottled water, simply on the ethics of it. But I would find it absurd and disgraceful to charge for tap water. Remember, this is a custom that is standard in many countries.

> Are you in Belgium?

Brussels. Sablon to be specific :)

> Perhaps a silly question, but why do you go for tap water?

60% of the human body is made up of water (some parts more, some less):

* https://www.usgs.gov/special-topic/water-science-school/scie...

Now there are certainly other beverages available, but at a restaurant the options are usually alcoholic or sugary. And if you're not into alcoholic drinks (lifestyle, health, or you are driving), and do not want to ruin your health with sugary drinks (pop/soda), what are the alternatives if you want something with your meal?

Yes, you can pay several dollars/euros for bottled water, but given that it is H2O, I'm not sure what value you're getting. Bubbles?

At some Asian restaurants they give you complementary (green) tea, which I like, but I still often ask for a glass of water.

After my meal I'm fine with getting a tea or coffee, but my friends and I usually do that at another place and not at the restaurant.

(I'm also not much of a beer or wine person, so if I order a vodka or whisky with my meal I get strange looks.)

>If I'm a restaurant owner and someone is taking up a seat while drinking free tap water, of course I'm not going to like that.

Not how it works. You get free tap water with your order. So no need to use up a plastic bottle.

In extremis you can sometimes walk in if a restaurant isn't busy, ask for a glass of water, drink it while standing, and leave immediately. You would never sit in such a circumstance

> In extremis you can sometimes walk in if a restaurant isn't busy, ask for a glass of water, drink it while standing, and leave immediately. You would never sit in such a circumstance

Perhaps I'm not used to it, but that sounds extremely silly and rude to me?

Like I said, in extremis. The same way you might ask to use a bathroom at a business you were not a customer at, or to borrow something from a stranger to solve a clear temporary need.

The sort of request that is granted with a smile if asked politely, and denied if asked rudely, basically. Part of the general fabric of society.

You would only ask if you'd been out a while on a hot day and were parched, or something similar. There's surely some social analogue not involving water where you live?

Lack of public bathrooms is a real shame and a failure in planning. It is a universal human right to access a bathroom in public places, or else be okay with people pissing and shitting wherever. I think the same should apply to water access. If no public access to water, businesses should carry that “burden”.
> Who goes into a restaurant, does not order anything, and asks for free ice water?

Never done that nor heard of anyone ever doing that. I've always ordered food/drinks and tipped at restaurants where I've gotten free water which is everywhere. The no pay example I cited is Starbucks which is an order and pick up coffee shop. I actually pulled out my wallet ready to pay for the cup of water but they were nice enough to give it to me for free which is probably a good idea in hindsight considering mint says I've spent $1200 there over the past 4 years and I appreciated that.

Starbucks is the only restaurant I've seen here in Belgium that will systematically give you tap water on request, no questions asked. They usually throw in some ice for you as well. I'm guessing they train their employees on that, because it's actually very non-standard behaviour over here.

Just the fact they do that makes me want to go there more often.

It’s not really charity, it’s a part of their business model. Same for bathrooms.

And Starbucks stock has never been higher.

I've never tried to go into a restaurant (or anywhere) and just ask for a glass of water, but I can't imagine anyone refusing one, even if you don't order anything. It's just basic courtesy.

Is that not what happens in other countries?

> "[fans don't] help when it gets above the 98.6 degree body temperature."

I'm not sure about that. It would be true with a spherical cow, but I don't think it's true when real people are involved because people sweat to cool down. I believe that phase change of water evaporating off your skin should continue to cool you down no matter how hot it gets, like a swamp cooler in Arizona. A fan should help this by rapidly replacing the humid air around you with more dry air.

(However my understanding is that evaporation cooling stops working once humidity hits 100%)

Humidity is the real killer. You can easily handle temperatures above 60C as long as the air is bone dry.

It's not 100% humidity, it's a flowing scale that depends on how much cooling you need to do via sweating.

If it's 10C outside, you don't need any sweating at all and the air humidity doesn't matter.

If it's 30C outside and 50% humidity, you're going to feel miserable, older folks could suffer under the stress.

From my experience, keep the sum of humidity in % and temperature in C below 100, better 80, to be comfortable.

I would say that if the fan is used as part of a ventilation scheme, yes the dehumidification, and moving air displacing hot air coming from your skin is helpful. If you're in a closed room you just get the benefit of moving air, which tends to be marginal.

As for humidity, the evaporative cooling from sweat should aid cooling until you hit 100% humidity (at which point sweat can't evaporate). But we're just talking about the mechanics of cooling here. If we're talking about human thermal comfort, which has been (with some debate) empirically quantified, thermal comfort only exists within a narrow band of temperature and humidity. So for example, a person sitting indoors clothed with typical summer clothing, will only be comfortable at a temperature of 27C at a humidity of approx 55% or lower (see this tool for more info: http://comfort.cbe.berkeley.edu/)

I looked it up and it seems that in England and Wales any place that serves alcohol must provide free drinking water, otherwise it doesn’t.

https://www.bbc.co.uk/news/uk-39881236

Explanation of alcohol licensing on the government website. Search for the word water.

https://www.gov.uk/guidance/alcohol-licensing

There is also a campaign about providing free drinking water for refilling bottles:

https://refill.org.uk/

The UK is pretty far behind France in the water department. I talked to a French couple who had just got off the beach and were looking for showers and drinking water. There are none at our local beaches. When they asked where they could go for a shower and to fill up their water ... I couldn't think of anywhere they could go for free. Showers and drinking fountains are all over France, along with free camping.
Well, for free camping, not evrywhere, but municipalities in the south often provide it as an alternative to the forbidden wilderness camping.
In Germany nobody drinks tap water. Just the notion makes as much cultural sense to them as drinking water from the toilet cistern does to you. It is just not the done thing.

Have you tried their beer? And why are you asking for water in the first place?

They always serve beer with extra consideration and thought put into the bierdeckel. You just don't get bierdeckel everywhere, this is quite a German thing, a matter of pride, customer service and a job well done. However, walk into an American bar and ask for a bierdeckel and you will get a blank stare. Even though bierdeckel are 100% safe, American waiting staff just don't want to do the kindness. To them any insistence on a free bierdeckel is just weird.

As for air-con in Europe. This is the last thing we need.

There was a time before air conditioning when it was possible to heat and cool buildings. The trick to it was not difficult, you just needed a stone or other robust building that takes a while to heat up during the day. A breeze running through the building due to having attic windows open and the front door open did a better job than any 110v fan. This was convection, just normal heat rising, with no external breeze needed.

This also worked well during winter albeit without the windows open for the cooling breeze. The physical mass of the building would keep it warm inside even if there were no fires in the hearths overnight.

America is different in that buildings are made from a few bits of wood and some PVC decorative covers. The specific heat capacity isn't right for natural cooling and, with the more southern latitude, the only way to survive is with air-con. This applies to the clammier parts of the American South as well as the dryer desert areas. Living there needs air-con. This is probably why people didn't live there in such vast numbers in the days before air-con.

But air-con is like a disease. People get used to it very easily and have to spend the rest of their lives with it. People are also vastly more spherical than they used to be and their lives are sedentary. As a consequence they can't regulate their own body heat. Their only option is to not enjoy the seasons and splendid weather, to be boxed in behind their noisy air-con machines with the windows closed and none of that natural temperature management that used to go on in former times.

As soon as the fatties that need air-con completely take over then that is game over for buildings that have served us well over the centuries with well considered solutions for natural temperature control.

Countries are getting hotter. Most of the hottest years ever have been since 2000. So countries, buildings, laws and customs need to change quickly.
> In Germany nobody drinks tap water.

German here - drink pretty much exclusively tap water. Ordering tap water in a restaurant definitely IS frowned upon (the restaurant has to choose putting it on its menu and/or accommodate your request) , but I have yet to meet another German who would take offense at drinking Kraneberger.

I guess there may be regional differences, but it's very clearly not universal.

> There was a time before air conditioning when it was possible to heat and cool buildings.

There are a lot of old buildings with thick walls as well as special building styles (like the Fachwerk that we apparently have a lot of, compared to other countries) that deal very well with heat and, I must admit, have a much superior air quality and just overall feeling of climate than any air conditioned building I have experienced so far. Perhaps those are adjusted to a very particular temperature profile, though, and if the climate changes, AC might start to make more sense.

I don't think we have very good experience with installing AC, though. Just an anecdote, but at my $JOB, we're housed in a very "modern" building with light materials, large windows from floor to ceiling, exposure to sunlight from dawn till dusk and a hilariously impotent AC (supposedly fed by an innovative ice storage something or other). The people in charge do a marvelous job of pretending, for years now, that it's a complete mystery why the ac keeps failing to move the needle - at the record heat of 39°C outside, the temperature inside climbs well beyond 32°C. But I guess that makes sense if you were responsible for making as basic a mistake as "building the walls too thin".

> As soon as the fatties that need air-con completely take over then that is game over

Aber sag uns doch endlich mal was du wirklich von den Amerikanern hältst, Klaus-Dieter.

Your skills with the German language are exemplary.

We really have lost it with this air conditioning. It should be evident that the feedback loop has gone wrong when, after centuries of buildings serving us well, we can't enter them without the aircon, lighting and everything else turned on, with all doors and windows shut.

It is like summer comes along and we have excuses for wasting as much electricity as possible, then winter comes along and we do it again. There is no let up to it and people aren't necessarily directly paying for air-con and other demands. They are also not aware that they are heating up their environment considerably with this over the top lifestyle.

Modern offices are absurd alien places. The water can't come out the tap, it has to be brought by a man in a van. You can't wash and re-use a cup, cups and eating utensils have to be single-use disposable. Need an expensive fizzy drink? Have as many sugar rushes a day as you want, there is a vast refrigerator full of the junk, humming away, not too far away, all of it for free.

The noise of ad-hoc air-con solutions and the moaning people make about air-conditioning is a phenomenon deserved of study. A lot of people really do have this overly corn-fed obesity problem that can't be spoken of because to do so would be 'able-ist' and possibly a sackable offence. However, if you had to provide A/C for a group of fit people or for a group of fatties, which do you think would have the lower electricity bill? Also, why should those that can stay off the snacks have to endure these fattie-friendly alien workplaces?

> Your skills with the German language are exemplary.

I should hope so, what with the being German and all.

The rest of what you wrote borders, again, on projection and doesn't seem to be a constructive way to tackle the issue that you do seem passionate but not sufficiently empathetic about.

A modern insulated building can sustain < 30 degree celsius if the outside temperature is 40 degree celsius. (If you open the windows at night to let the building cool down or have other methods of air exchange.)

I don't think building a/c everywere is the right solution if we suffer from climate change due to our energy consumption habbits...

(And I was never refused free tap water in Germany. Puzzling.)

I'm all for passive and natural cooling, but that involves new buildings.

Central AC is still a lot more efficient than "every apartment gets individual AC", which is the norm in eg. Athens.

Ductless mini-split heat pumps would work well and are quite efficient.

Each apartment can get a separately metered unit, with one compressor serving multiple indoor air units. The indoor units can be in different rooms, each set to different temperatures, with different schedules (why cool the bedroom during the day?).

Typical units can heat the home to >20C even if the outside temperature outside is 5C, and there are even units that can extract heat from outside when it is -20C (originally designed for northern Japan).

Am I missing something or does this not help with air conditioning? Heating in europe is pretty high quality overall; the problem is with cooling.
Heat pumps transfer heat.

In the summer they take heat from inside a building, and dump it outside. In the winter, they extract heat from the outside air and send it inside.

The same unit does both heating and cooling.

You also do not need to renovate a home as much to install them. Traditionally air ducts are often used for a lot of HVAC, and they can sometimes be a hassle to retrofit into older buildings. Heat pumps using ~1-2cm pipes between the external compressor and internal 'heads' to move the heat, so it's a lot easier to run that pipe (like plumbing) than a much larger air duct.

> A modern insulated building can sustain < 30 degree celsius if the outside temperature is 40 degree celsius. (If you open the windows at night to let the building cool down or have other methods of air exchange.).

Great! Now all we have to do is tear down and rebuild old buildings, coordinate window policy with hundreds of tenants, and build out expensive air exchangers that don't run on electricity. That is much better than AC.

Or retrofit the old buildings? Or go visit a friend living in a cold building for a day? Or bike to a nearby lake and enjoy the swim?

There are so many things we can do if we just want to... do we really need to put our personal comfort before the healthyness of our planet?

This hippie idea that if only we weren't so selfish we'd be better off isn't exactly useful.

Yes, if only we weren't so selfish, we'd be better off. What's the action item here? People are selfish and self-centered and are going to put their personal comfort above the health of the planet. And since the health of the planet is important, and you can't change human nature, then we better figure out real ways to make personal comfort be less harmful to the planet, rather than rely on "friends living in colder buildings".

If you are certain that "make people less selfish" is no goal for actionable items and people are only comfort driven, there is another simple solution: Reduce the comfort.

Make them pay more money every time they show descructive behaviour. Tax them for it.

There's an even better solution: make the "destructive" behavior not destructive.

Instead of taxing elderly people for selfishly installing AC so they don't die, we should focus on improving technology such that running AC is not harmful to the planet.

Using taxes to reduce bad behavior can slow down climate change, but it could never stop it. Technology is the only real solution.

Heat waves are not personal comfort matters. That's why they're a big deal. If they were, they wouldn't be heat waves.

For those with compromised thermoregulation systems, primarily the elderly and the sick, and especially those who also lack an appropriate support network, most of the heat mitigation techniques other than "be in a cold enough environment" will not work.

They'll just figure it's a normal but unusually hot day. Then they get heat stroke and die. It's very easy to not notice it's happening to you until it's too late; there are known cases of people dying at (or after) sporting events on hot days due to this.

Yeah. That's totally just a "personal comfort" problem.

> Now all we have to do is tear down and rebuild old buildings

Or use 2" / 5cm of closed-cell spray foam to air seal buildings to reduce drafts, and then add more insulation to reduce heat exchange/loss.

(You can spray foam more, but it can get expensive and batt insulation can be just as useful.)

AC is not the solution, it is part of the problem
> In most of France, Belgium or Germany it's impossible to find apartments with ceiling fans or air conditioning.

I live in Germany, in a house that's nearly 500 years old. There's one room that's holding up well against the heat, but the rest of the house is getting uncomfortable.

In the past there used to be days that were this hot, but now it's the second year where we get weeks and weeks of >30 degrees. Air conditioning was just not necessary so far, but I'm seriously considering adding some.

> Possibly the worst offence in Germany and especially in Belgium is that you can't ask restaurants/bars for tap water.

The discussion is a bit unclear what you mean here, if that's about tap water at the table, or tap water in general.

When it's hot, I never had issues asking for a refill of a bottle I bring along or a glass of water "on the go". I'd stand near the counter, drink it, thank them, and go my merry way.

Tap water at the table is a different matter, and yes, it's uncommon here and you might be considered a cheap-skate, as drinks are part of the calculation to make things work (food really is cheaper in Germany than in many other Western countries though).

Air conditioning is part of the problem, not part of the solution.
The point is to make it part of the solution.

It's like saying "electricity is part of the problem" well duh, that's why we're moving to green energy and more efficient power usage. We're not just gonna stop using electricity.

Sure. But unless we discover some truly green energy source which is able to reliably deliver an abundance of energy (hint: we haven't yet), we will always have the situation that the amount of available green energy is somewhat limited. Thus, we need to save energy.

Weather forecast says London is going to be 38 degrees tomorrow, with a humidity of over 60%. Railway companies are telling me not to travel tomorrow because the heat is likely to disrupt train services. Tube lines without air conditioning are going to be dangerously hot. I don’t know how this city is going to function tomorrow. Maybe it’s something we need to adapt to.
This happened a couple years ago on ICE (Inter City Express) trains in Germany: https://www.spiegel.de/international/germany/the-world-from-...

> As temperatures soared to 38 degrees Celsius (100 degrees Fahrenheit), the cooling system on many ICE high-speed trains simply switched off, leaving passengers to swelter amid inside temperatures of up to 50 degrees Celsius (122 degrees Fahrenheit).

> "A company that has aspirations to be a high-tech firm, but one which soft boils its customers instead of bringing them comfortably to their destination, has more than a small technical problem."

Wow, don't suppose they could open a window !
The ICE does not have windows that can be opened because it is a high speed train traveling at 200-300km/h.
I'd rather boil than open a window at 280km/h
All those other people who cook, use lights and computers, and rely on transportation are killing us.
Apparently England might break their highest temp and they have a record dating back pretty far.
> The Belgian town of Kleine Brogel hit 39.9C (102F), the hottest since 1833.

Global warming is causing the heatwave now. But what caused the heat wave in 1833?

Short-term climate fluctuations caused both heatwaves, and global warming has made this one a little worse than it would otherwise have been.

we should honestly stop yelling climate change and global warming whenever it gets too hot or too cold. That's NOT how it works and the only long term effect will be to create more doubts around climate change.

OK...I'll be the pedantic nit-picker and bring this up: 39.9 C is 103.83 F. How the heck did they round that to 102 F? I can see 104F or 103F, but 102 F!?

Or maybe they got the report as 102 F and calculated C from that? No...that doesn't work either. 102 F is 38.889 C, so should have rounded to 38.9 C if they wanted one decimal place, not 39.9 C.

Also, might as well nit-pick this too...there is supposed to be a space between the number and the unit symbol according to the rules for SI units, except for °, ′, and ″ when used to denote angles in degrees, minutes, and seconds, such as 14° 13′ 41″ [1].

I could see omitting the space if they included the circle, such as 39.9℃ and 102℉, since the circle keeps the C or F from being unpleasantly close to the number.
