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 up and at least one window air-conditioning unit if not a heat pump before next summer

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.by bcoughlan

It's clearly an op by people who don't want the story to be about a historic heatwave ravaging Europe, so instead they make it about dum Europeans without air conditioning (which they didn't need before).by jordanb

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 their presence is increasing.

It would be one thing if Europe immediately stopped using coal, drastically reduced airline usage, quit building gasoline cars, but if anything it is only marginally better than the US. Europe mostly shifted their dirty work to Asia and North America, while restricting themselves from using air conditioning as some kind of virtue signaling. That's the problem as I see it.by yostrovs

So we've been stupid "solar oven" buildings for 50 years while climate scientists were warning against extreme weather events and, now that said extreme event arrives, the best we find is to rush to aircon.Seems pretty short-sighted to me.

I live in SoCal and am continually shaking my head at the architecture. So my floor-to-ceiling glass buildings in a climate known for sunny weather. So much extra air-conditioning will be spent to cool those buildings compared to if they had been built more reflective.by 3eb7988a1663

I feel every comment section related to weather and climate seems to have the same winging about buildings. Cold? Europe has amazing buildings, hot? Europe has been building ovens... it's interesting psychology.Edit: We cannot blame people for buildings things that worked when we had a stable climate but are no long suitable for all these extremes. We needed to fix the emissions issue 30-50 year ago to avoid this. We knew it and we collectively ignored it. I get your point, we could've "planned ahead" but if you build something that wasn't suitable / cost effective for the time it was built, you'd be out of business.
50 years ago no one was going to pay extra for a building that might be important in 100 years because we didn't stop burning fossil fuels in time.

> you'd be out of business.Correct. And we'd be "out of business" too as a country if we decided alone to fix emissions. Other economies would have passed ours because burning oil is so damn useful.
Thing is, I don't feel we are changing much in this respect. Now the best idea we come up with is burning more fuel for aircon...

For shadow, reftrofitting adjustable sunshade is pretty effective. Sunlight brings about 1kw per square meter of window. That like having your heater at full power when its already hot.
For wind: fans, preferably ceiling fans. Lowers perceived temperature by about 3.5 °C.

Uncomfortable heat has nothing to do with temperature and everything to do with air humidity. Only an AC can lower the humidity, by conditioning the air.by carlosjobim
7/26/2026 at 9:19:24 PM
> Uncomfortable heat has nothing to do with temperature and everything to do with air humidityThat is not correct. Heat, wind and humidity all contribute.
In a dry air with no wind, your body creates a "hot and humid" bubble around it if you are not moving. A fan helps.
Humid but neither cold nor hot air may not feel great, but not that bad.
Hot and humid air with no wind, now that's bad.

I live in Europe. We have in fact invented air conditioning here too, but I am not concerned with what we should be doing next year. That's a trivial matter. I'm concerned about what will happen if this trend continues another 5-10 years. How do we make sure that doesn't happen?by delusional
7/26/2026 at 9:24:08 PM
> How do we make sure that doesn't happen?That's the neat part, you don't.
Europe has saved on CO2 emissions by moving production to China, and more recently to India and Southern Asia, moving energy generation for factories onto coal power, significantly INCREASING the rate at which climate change occurs.
China and India have made it very clear that, first, they will continue to do this. Also adding solar power, but not lowering coal power. They added that it is "inappropriate" to even ask them to do so (that was China).
Oh and thanks to reliance on Russian gas, and the Ukraine war, the EU is forced to move to coal and LNG supplies, which are even worse than coal. Plus, of course, that means that it's not just coal plants getting worse for climate change but almost all power plants in Europe.
To do something about it, due to Jevon's paradox the only countries that can lower CO2 emissions are the ones digging up fossil fuels. Saudi Arabia, Russia, Venezuela, US, Norway, the Netherlands, Britain. You have zero chance to convince any of them to stop doing it, burning and selling oil, not even Norway is doing that. And any oil or gas dug up and sold will be burned.
There never was any serious intent, not even on the part of the greens (at least not in Germany, I mean, they even published an article on the subject: eliminating nuclear power was more important than climate change in 2003). And if even they weren't willing to make it a priority, who exactly are you supposing will do it?
Even in 2026, even Germany, increased it's reliance on coal (they're keeping 10GW of additional coal power at the ready, on top of the 20% of Germany's power that's constantly using coal), similar measures have been taken in Japan, Italy, and India has even delayed maintenance on existing coal power plants to increase electricity production from them.
And of course, there's the basic physics part. Aside from a small rounding error climate change is cumulative. Which means once fossil fuels are burned the temperature will rise accordingly. Even if we stopped burning it won't get better.
To merely stop climate change from getting worse, just that, nothing more, we have to cut CO2 emissions worldwide by 99.7 (and some models say 99.97%, there's a surprising range there). That will just stop it from getting worse. It won't make it better. Anything less is not "a good effort" it simply makes things worse.
All policies taken so far to stop climate change have not just made things worse, but increased the rate at which it's getting worse. Doing nothing at all would have been a lot better (because it would have kept factories in the EU going, on much cleaner power).
Oh, and by the way, this was all perfectly clear and known 10 years ago, and nobody changed course. So ...
There is no remotely realistic solution in the current policy directions.
And geoengineering ... is not really allowed to be discussed. Or this argument is being put forward at the UN. Any (successful) geoengineering will have dramatic negative consequences for some states and people. And since that is considered unacceptable, because large portions of the human race are currently dependent on global warming continuing. We won't do that either.
So yeah, I'd get some solar panels and an air conditioner.

Most aircon in "warm" europe is standard split aircon
The "heatpump" shit that the UK is sorta looking at is as you describe. However its half the price to install "aircon" over heatpumps (because grants, amongst other things)
Like most recently refurbished offices will use normal aircon (certainly all the one I have worked in)
by KaiserPro
7/26/2026 at 7:43:51 PM
The annoying thing is that UK at least has a bigger grant for air-to-water systems.I've been doing some research into this, because I would ideally like to get this system so I can make use of the existing radiators in my old house, but I do also want to have the option of cooling my home. It does seem like Fan Coil Units (FCUs) are an option for this. Anyone have experience with these? Are they really inefficient compared to standard air-to-air units?
by dom96
7/26/2026 at 7:53:57 PM
The problem is, if you feed cold water into your normal heating pipes, all the piping and radiators will get wet from condensation. So you would have to have a regulator that measures air moisture and temperature in all your rooms and only feeds water with a temperature above the dew point. This is possible, but inefficient and (especially on hot+wet days) doesn't cool very well.The possible real fixes are either to section off your water circuits in summer, and only run the properly cold water through FCUs, wall or ceiling loops.
Or to get a multisplit heat pump, use a normal refrigerant-air indoor unit to cool and a refrigerant-water indoor unit to heat the water loops.
by thyristan
7/26/2026 at 8:23:50 PM
Yeah, I wasn't planning to run the cold loops through the existing radiator piping. I just want the ability to cool at least 1 room by reusing the air-to-water system, even if that means the FPU requires its own piping from the outside.In that scenario, are FPUs a good option? Are there other drawbacks?
by dom96
7/26/2026 at 8:57:24 PM
Most Francoils I know don’t have a way to get rid of any condensation that happens in the unit like internal air conditioning units do. So even if you run the piping outside of the house you have condensation in the unit and the floors, not to mention the walls.Even then, there is a fair limit in cooling and efficiency you can get from them because of the lack of phase changes occurring.
If you have a balanced mechanical ventilation (both inlet and outlet) that would be one of the best options to condition the whole house without putting air conditioning units everywhere. Having said that, we turn on the air conditioning in the attic during hot days which removes the biggest heat and moisture from the house. Next up is installing more sun blinds to prevent the heat from entering in the first place.

And by a sizable margin they mean maybe 4 degrees Celsius.Remember that 1.5 degrees Celsius is a nearly end-of-the-world scenario and we're currently about 1.1 degrees.

We are looking at more severe droughts, flash floods, and rising oceans where we are at, but not the worst of it like mass 40C wet bulb heat domes which wipe out all life underneath them.
by cogman10
7/26/2026 at 9:03:19 PM
This is an incorrect way to frame the impacts of temperature increases. 1.5, 2, 3C makes extreme events like the one you stated significantly more likely in a probabilistic sense. The ability of adapt is in part driven by frequency of extreme events as much as it is adaptability to specific thresholds. We are already experiencing deadly heat bulb events at current warming levels, the impacted areas and frequency of these events will strictly increase.by jakebol

You are right, it is an exaggeration.I should have said "land life" as the ocean temperature doesn't shift that much with the above ocean temps.
And I'm sure there's some random bacteria and fungus that can survive and thrive at 40C web bulb.
What doesn't tend to do so well is the likes of humans, birds, cattle, horses, mice, rats, insects, many crops, native animal life that didn't evolve to handle high heat temperatures.

The 1.5C target (which, as others pointed out, is not an end-of-the-world scenario) is about average temperature above pre-industrial baseline across 20 years. The temperature anomaly of a single year has nothing to do with that; 2028 will likely be colder again.Average temperature moves in cycles. By confusing single-year temperatures with the 1.5C target, you're just going to make people think "crisis averted" once 2028 turns out to be cold.

the oceans can adsorb a great deal more heat, but all the ice will melt, while the deap ocean water expands, from it's rather odd temperature ,that keeps it at the highest density possible, about .5% more than if it were just a bit warmer, so more warming will cause very significsnt sea level rise through several different mechanisms related to heat.by metalman
