> Even when night time temperatures drop to 17c That's pretty nice actually! I am in a brand new rooftop apartment, so pretty exposed to heat. I can keep 28-29C indoors when it's 38C outdoors. That's hot but workable with a ceiling fan. At night we open all windows and have a ceiling fan above the bed. We've got about 24C indoor in the morning, with nightime outdoor temperature at about 21C. Obviously I keep physical…

17c outside just to be clear, highlighting that that it doesn't serve much purpose in cooling inside the house We also have high humidity which makes 25c to 30c at night very uncomfortable for us Brits. People often forget about humidity when telling people they don't need AC And you have to remember we're a country of people used to max summer heat mostly being around 20-22c and many people will sleep with the windo…

> People often forget about humidity when telling people they don't need AC

True that it is not so humid here in the French alps.

But to be clear: do get an AC if you need to. Please dont rely only on your AC though. Turning on the AC (eg just pressing a button, really) is so easy we tend to forget about the rest... and end up burning even more fuel.

Yup. Built a house in 2016 in Belgium. Perfectly insulated. You didn't have to run heating in winter. Kept it all inside. Also, it overheated instantly.

One way insulation does not exist. If your house is insulated to keep the heat inside, it is also very good at keeping the heat outside / cold inside. Also tangentially many Europeans seem to be confusing insulation with inertia, saying their house is correctly insulated against the heat when in fact it’s just a stone building that is taking more time to heat up. At the extreme you have European churches buildings th…

> many Europeans seem to be confusing insulation with inertia

That is true. I heard that many times...

> during a strong heatwave there is no adaptation possible, AC is needed.

At some point, yes, obviously. But in many cases I see people installing an AC without actually trying anything else. And then it is an energy orgy: AC set to 16C with sunlight hitting straight to the middle of the room...

We can install adjustable shades and ceiling fans. Cheap and efficient. It practically pays for itself in saved energy bills if we decide to add an aircon anyway. Plus the saved energy saves carbon emissions too. We can update building regulations so that new building are better. We can plant trees. It brings shade in summer but lets sun through in winter. We can stop taking the plane. I mean, there really are tons o…

It's 38 degrees this Wednesday again, and you're talking ceiling fans. This is just ridiculously out of touch.

For the record, I live on a rooftop and it will indeed be 38C this Wednesday at home (Grenoble, France, not a fresh place). No AC, fans, shutters, some shadow and, admittedly, some sweat.

I know I will need an AC one of those years but for now this is fine for home working.

I just toured Europe and none of the lodgings (private dwellings) had AC. It was not fun when it was 35C out. South of Spain is actually one of the most comfiest places to be in summer despite being hotter on average, because many homes have AC due to it being cheap to install (and to my knowledge being run on near complete renewable energy).Some European countries' stance on this is bizarre, like Switzerland outrigh…

"Switzerland outright not allowing residential ACs": That's not completely true, though. First, mobile/portable ACs are allowed pretty much everywhere in Switzerland, I think. Then, for fixed ACs, it depends in which canton you live. Geneva is the strictest, but in most cantons, fixed ACs are allowed under some conditions. Where I live, 50% of the AC energy must come from renewables (which is pretty easy if you have…

Great when mobile ACs are mostly terrible, if-nothing-else choice. They can only cool a small room temporarily.

In case you don't know, there is a meme in the US that Europe don't know/don't have A/C. We do, but in some coutries there are laws banning A/C below 25°C (77°F) in public places, so (US) tourist don't get the cold air hit when entering a building like a musseum, leaving with the impression we don't know A/C. No general A/C might be the case in regions that never needed it before (mild summers, cold winters), but the…

>but in some coutries there are laws banning A/C below 25°C (77°F) in public places, so (US) tourist don't get the cold air hit To be fair - cold air hit (I'm talking about big gaps betweet temperatures) is pretty bad for you. Ideally you don't want the temperature in a room to be (immediately) lower than T-5°C or so.

I think these T- rules haven't really been thought through at temperatures reaching and exceeding 40C.

> Insulation is actually helpul against heat too! Yes, until you reach that tipping point where once warmed up, you can't cool down anymore.

I don't know your situation but surely you've tried ventilating at night and then closing up the house at a specific time in the day? I only ask because when I moved from the US south to the high desert in NM (about 2KM) I had to learn how to time that transition. Very few folks here run A/Cs, we generally have homes designed to stay warm and during the summer usually fans go on about bed time and off in the morning,…

Ventilating at night doesn't work at all when nights are hot. And now it happens oftenly, not sometimes. That is a bigger problem than hot days.

Also, all the activity you do inside your insulated home also increases temperature. Human body itself is a small space heater. At some point, you gotta get that energy out somehow, and if nights are hot, there is no way to do that except via a heat pump.

The buried lede: What does all this mean for global temperatures? Because global temperature lags ENSO by around three to five months, most of this event’s warming will land in 2027, which is now shaping up to be a genuinely alarming year and the warmest on record by a sizable margin I’m certainly no climate scientist, but if I lived in Europe, I would absolutely be looking into how to get a solar energy system set u…

I don't mean to be divisive, but this meme-like stream of news articles and comments about Europeans being silly about air conditioning, from the drill-baby-drill nation that refused to even try to do anything about climate change, really grates on me.

It should be more grating that Europe's refusal to adopt air conditioning is murdering their most vulnerable at rates comparable to American gun deaths and (unlike climate change or gun violence) there's a trivial solution that would prevent this immediately instead of waiting decades.

It would be great for you to experience living close to one of these data centers [0]. Maybe you'd have a consideration outside of your own myopic view then. [0] https://www.selc.org/news/xai-built-an-illegal-power-plant-t...

Yeah, as opposed to the very pleasant living by the side of a steel mill and an oil refinery. What is myopic is chasing social media "evil of the month" trends, instead of looking at the actual data.

Yeah, except those aren't being built in areas where people already live. You do realize that a refinery lasts 50+ years and the OECD already has surplus capacity? So why would there be significant spend here? Meanwhile DC starts totaled $25B+ in January of this year [0].

Maybe you should try providing some data given your comment, I'd be interested in hearing about all of these refineries and steel mills being produced!

I'd try hanging long sheets of aluminum foil in too-large windows. I imagine someone in academia has studied this.

That works. A lot of people do that in their home when they have no other choice (renting the place, typically). It'd be better to block the sun before it hits the window though, so that the window itself does not get hot and heat the inside. Edit: people generally use emergency blankets, fyi. You can stick them to the glass with water.

I've read a few times now that applying reflective foil to the inside using water can lead to broken windows - though I can't remember any linking to statistics or studies, so it could also be false or very rare.

There's a lot to criticise of every country, but we're trying. The US is not trying (*) https://en.wikipedia.org/wiki/Paris_Agreement#/media/File:Pa... * Not aimed at all the wonderful, sane and reasonable people of the USA.

> The US is not trying https://usclimatealliance.org/ I don't expect people outside of the U.S. to keep up on state level politics but it is worth noting that many in the U.S. are trying and given our form of government state level action isn't anything to sneeze at.

Go stand in your local Walmart parking lot and ask ten people if they know what the climate alliance is or if their state is in it. I'll wire you ten fresh bucks if you find one person who has an idea what that is,
