A heatwave continues to grip large parts of Europe, with authorities in many countries issuing health warnings amid searing temperatures.

Southern Spain is the worst-affected region, with temperatures in the mid-40s Celsius recorded in Seville and neighbouring areas.

A new heat record for June of 46C was set on Saturday in the town of El Granado, according to Spain's national weather service, which also said this month is on track to be the hottest June on record.

The last years saw up to 50°C in Northern Africa already. This will be the fate of Southern Europe, as the peak temperatures in the center and North of Europe will go to 45°C.

As the mean temperature rises roughly linear, so do the peak temperatures, but at a much faster rate. So 1,5-2°C increase in mean temperature often correspond to 5-7°C increase in peak temperatures.

Well, that depends on whether the Atlantic Meridional Overturning Circulation stops working or not as that's what, for example, means that Lisbon which is roughly at the same latitude as New York has a temperature which is about 5 - 10C higher.

One of the weirdest effect of Global Warming might very well be that the westernmost parts of Europe get colder (though who knows what other side effects the stopping of the AMOC will bring beyond reducing the temperature moderating effects of the Atlantic along the Westernmost coasts of Europe).

I would right out melt getting out of the plane.

If anyone is interested, it's X Celsius times 9/5 + 32

"Double it and add thirty" is accurate enough for ambient temperatures, and easier to do in your head. If you need scientific accuracy then you wouldn't be using Fahrenheit anyway.

Maybe? But 122 is way different than 114 in this case.

As this keeps happening I continue to wonder when Europe and the UK will finally realize how badly they need to air conditioning. The units are (or were in the past year or 3)b way more expensive there than here in America. I dunno about current costs. It's worth it though, even if you only need it for like 1 month out of the year.

[–] brewery@feddit.uk 9 points 20 hours ago (2 children)

We're very aware in the UK but it's not too easy. We have some the oldest housing stock in the world. We don't have central air with no real way to retrofit so it would have to be one room at a time. Our windows aren't designed to house those units I see in NY. We have to rely on very inefficient portable units so I only use it on the really hot days. Energy prices are still high after Russia's invasion. People are adding proper units when extending but only the rich can really afford that.

[–] squaresinger@lemmy.world 7 points 19 hours ago

Add to that, that all these old UK houses have about as much insulation as a cereal box.

I live in Spain, and since temperatures are now reaching 39°C in my area, I ordered two AC units for the most used rooms in my house (living room and bedroom).

With installation it costed 1300€. A months salary basically. In my area the cheapest unit with installation was 450€, but it didn't look very reliable.

I ordered it 11 days ago, and I'm scheduled to receive it and installed either this week or the next. AC installers are oversaturated with orders this time of the year. It's insane.

In France the government is helping people get Aircon by subsidising heatpumps, also way more carbon efficient than Gaz or fioul based central heating.

[–] BastingChemina@slrpnk.net 10 points 23 hours ago (1 children)

It depends on the kind of heatpumps, in a lot of cases the heatpump is installed to replace a boiler, reusing the radiators and hot water circulation already available.

Unfortunately in this case the heatpump cannot be used as AC.

[–] SpongyAneurysm@feddit.org 6 points 19 hours ago (1 children)

Not as AC, but a reversible heat pump can use the heating system for cold water circulation.

It's rather limited, because you run into condensation concerns, but it's still a possibility. A place I used to work at did this. It wasn't perfect, but took some of the edge off.

[–] BastingChemina@slrpnk.net 3 points 18 hours ago

On the other hand reversible heatpumps work great with floor heating.

Having a cool floor during a heatwave is amazing, plus no noise,

They are trying to push people to heat pumps (basically air conditioners tech wise)

They are also moving towards building/efficiency regs that require completely sealed houses and forced air systems in new builds.

So new houses will effectively be required/encouraged to have an air con capable houses.

The old housing stock though? Oof. I'm on a private estate that even bans that kind of stuff!

Was just talking with my friend from Latvia who said it has been the coldest end of June since forever. Climate is so fucked and its just the beginning.

Could we build a huge glas dome around a city, with adjustable mirrored / polarised surfaces to block out the heat using electricity to alter the properties of the glass?
