As part of Fraser's observation that climate change is hitting across the pond harder than North America and faster in the Alps than in the lowlands -- he expects temps in London to be in the high 90s by mid-next week and even worse for France with wide sections hitting 105 for several days and the potential for a Death Valley-like 113 in places. Yikes.
 
My observation is that climate change affects:
1) Inland areas more than coastal areas
2) Summer more than winter, especially in the inland areas.

So in terms of skiing what is most visible is the shrinking summer glacier season in the Alps. North America's summer ski scene is way more limited, and I may have presumed that the locations (Blackcomb and Timberline) in coastal mountains with cooler summers would help them. But 2024 was the last summer for Blackcomb and Timberline's closing date has retreated by a month in the past decade.

As for winter, the Alps have a ton of local resorts that developed gradually after WWII out of very low elevation villages ~1,000 meters. These areas always saw their share of rain, but the balance has tipped more against them in recent years.

I don't know that much about the finer details of Euro climatology. In particular what might cause these summer events where hot air comes up from the Sahara and blasts Spain and much of France? I am in general suspicious of claims that climate change is the driver of unusual weather patterns like that.
 
France with wide sections hitting 105 for several days

The NY Times says: Only an estimated 20% to 25% of households in France have air conditioning, with Paris apartments having an even lower penetration rate—often cited as low as 2% to 5% for private residential units.

Unreal, but not atypical heat anymore.

I did not know drowning deaths get added to heat fatality numbers.

Hundreds of people all complained about the same thing in the comments -- that the article put the 40 drownings in the headline then didn't bother to explain their circumstances. Difficult to believe that Brittany of all places reached 106F; however, western France seems to be getting hit hard by recent heat waves.

That's insane. The North Atlantic region of France generally has moderate to cool temperatures.

And I was always curious about the 'Surf Culture' of San Sebastian and Biarritz. Seemed rough and cold to me, but so is NorCal. Scuba and surfing, even in Santa Cruz/Monterey Bay, are not something I want to do too often.
 
I guess it's a question of which scientists you believe?
It is logical that severity of these events would be greater. Frequency is the more debatable point. In the case of hurricanes, the data is clear that severity is up and frequency is not.

We have these heat dome events in the western US and my impression is similar to the situation with hurricanes.

I have learned that extrapolating western North America climate patterns to other parts of the world is often not a great idea. And Europe has very unique climatology due to the Gulf Stream. I would like to see some long term data from Europe. We know that global warming effects are not uniform by region and are specifically much more in the Arctic. I read yesterday that overall warming in Europe is about double the worldwide average. Extreme events also tend to exceed past records by more than the increase in average temperatures. So I don't dispute:
As recently as 2003, a heatwave like the current one in Europe would have been 2C cooler due to the lower level of global heating at the time. In 1976, another famous heatwave year, it would have been 3.5C cooler.
Our March meltdown in the western US ski areas this year was anomalous to what's happening in Europe now. But I see little discussion about frequency. FYI I was skiing in Colorado at NASJA meetings in late March of 2004 and 2007, coming at the end of 3 week warm and dry spells. But those events started with normal snowpacks so enough of it survived when snow resumed at the end of the month. 2004 Season Analysis:
The storms moved north for the first week of March, but warm and dry weather dominated the entire western U.S. for nearly 3 weeks, with only western Canada getting significant new snow. Snow was degraded on sunny exposures and the snowpack declined as much as 30% in a month when it is usually still increasing.
2007:
There were substantial storms in Utah and some northern Rockies areas in early March, but most of the month substantial new snow was confined to western Canada, so most of the U.S. West went to spring conditions in the warm weather, with even some trail closures at areas with below average snow depths.
No question the actual temperatures were hotter in 2026, but I don't believe frequency of these events is up in the western US. I have an open mind about Europe, but would like to see hard evidence.

European soccer fans enjoy a brief fling with America’s air-conditioned culture
Despite a deadly heat wave at home, many say they won’t permanently embrace Americans’ electricity-guzzling amenity.


The British food vlogger tried barbecue in Dallas, bagels in New York and cheesesteaks in Philadelphia, but when he returned to England from his World Cup trip, another American specialty dominated his thoughts. “Absolute bliss,” he recalled. “The best thing in the world.”

That would be air conditioning.

Jono Yates, 39, fixated on the 62-degree comfort of his Hilton hotel suites like a man tormented by forbidden love. They probably weren’t meant to be — the YouTuber and the cool blast. Could he actually splurge on a system he’d use maybe a few weeks each year? Or was it months now?

Summer in his county, Cheshire, was getting hotter as Europe suffered its most blistering heat wave on record. Schools shuttered. Train tracks warped. Dozens regionwide have died from heatstroke and drowning. Brits sought relief in bathtubs and baby pools in a nation where an estimated 4 percent of households had what Yates called “air-con,” compared with approximately 20 percent on the European continent and 90 percent in the United States.

The World Cup is drawing hundreds of thousands of international tourists to one of the most climate-controlled places on Earth, introducing soccer fans to the sensation of getting goose bumps at a Buc-ee’s gas station. In bars and restaurants, shuttle vans and stadiums, visitors gushed about their dry-armpit experiences before heading back to countries where a combination of cost, custom and environmental consciousness made America’s level of artificial chill a near impossibility.

In the week since he unpacked his suitcase, Yates had been sweating in “the shortest shorts known to man,” he said, while tossing ice chips to his panting shih tzu, George Michael. His electric fans blew hot air.

Escaping this inferno, he knew, required more than cash. Installing AC simply wasn’t the British thing to do. He’d have to break a stiff-upper-lip mentality and make peace with a trade-off that Europeans tend to view as taboo: Air-con accelerates global warming. Still, his mind kept wandering back to a Starbucks he had visited in Los Angeles. “It was so temperate,” he moaned. “So beautiful.”

Invented 124 years ago in Brooklyn, what the U.S. government lauds as “one of the most important inventions of modern times” became an American staple by the 1960s, bigfooting greener cooling techniques embraced elsewhere in the world. Developers could “build the same box in any climate,” one architecture professor lamented, thanks to the rise of power-guzzling, temperature-lowering machines.

Cue the transatlantic culture clash. In Europe, where homes tend to be older and climes fairer, residents mainly favored cross-ventilation over machines that leaders cast as pricey spewers of greenhouse gas emissions. “It’s like living in a sealed jar,” one French columnist complained of AC in 1994. “It’s unbearable.”

This week, as their home countries faced perilous heat that researchers warn has become more common, some European travelers swapped the teasing for awe.

“It’s like stepping into a fridge!” exclaimed one British journalist in a TikTok post.

Another offered a lighthearted Instagram concession.
“One thing the World Cup has taught me is that Americans might be onto something with this air conditioning stuff,” mused Victor Vacheron, a 35-year-old comedian and software designer.

Scrolling through clips of his fellow Europeans discovering America’s cultural quirks, he reflected on the mounting heat-inflicted deaths in Europe, the fastest-warming continent. At home in Brighton, Vacheron was lucky enough to hole up somewhere safe, even if his “heat dome” refuge was little more than the bathroom with the lights off.

Vacheron wasn’t sure if mass AC adoption was the answer. Perhaps cleaner interventions, like stronger insulation and more green spaces, could save lives. Managing extreme weather, he noted, was sparking political debate across Europe. One of the heads of France’s far-right National Rally party, for instance, just pledged to back a “massive” air-conditioning plan.

“When we were growing up, it was so rare to have the kind of temperatures we are having now, that it was like, ‘We’re not going to rework the whole infrastructure for two or three days,’” Vacheron said. “But now ‘two or three days’ is summer.”

Not that the American way is universally appealing.
At a Germany-vs.-Ecuador watch party Thursday in the nation’s muggy capital, Juni Hoppe said she preferred to keep her windows open for moral and, well, sensory reasons. “I don’t like the annoying zhuhhhhhhh sound,” said the pastor, 37, who moved to Washington from Berlin in September.

On broiling days, however, she enjoyed not sweating through her jeans. Pitchers, the bar where she gathered with other Germans, had set the temperature to what the owner called a “sensible 72.” It was fine, she thought, though one of her countrymen had asked if they could make the room warmer.

Growing up, her family didn’t have AC. She couldn’t think of anyone who did. People mostly opened the windows at morning and night and avoided strenuous activity during peak rays.

Hoppe was still negotiating a relationship that felt healthy with the central air in her D.C. apartment. On the days she adjusted the thermostat downward, she liked to travel by bus rather than car.

“To offset the emissions,” she said.
 
through my limited travels in Asia. I noticed every apartment building/ apartment has split system compressors mounted on it's exterior...Thousands of them...The new systems sip electricity , I have one too... IMO the brits aren't being eco conscience , just cheap..;)

Split systems are very common in Oz too. Until about mid 1980s the only air cons were the 'window rattler' box style variety. (Do you Americans use that term?) Since then a lot of the pre 1980 built homes have had split systems retro fitted.
I myself have ducted air but only use it about a dozen nights a year on average. Aside from my aversion to unnecessary cost I dislike the feeling of going from conditioned air into the ambient heat and humidity in summer. It's like getting a punch in the face. Ceiling fans for the win in my opinion.
Ceiling fans are cheap to buy and in most cases install too. The Poms and Euros should consider them.

When I moved into my current house in 1984, one room had a window A/C unit and two others including master bedroom had ceiling fans. We got central air in 1990 because my ex was home with a baby and 4 year old and decided we needed it. You could argue it's an indulgence here, as our central A/C was never on through July last year and was on for about 5 hours during that March heat wave so far this year. We have an advantageous location with marine air drifting through our house all night. No A/C needed with ceiling fan when low temps no more than 65F.
split system compressors
??? Both the old 1990 forced air and the the 2025 heat pump have the compressor outside the house with refrigerant flowing under the house to the evaporator coil in the basement. Is there any other way a forced air system for an entire house can be designed?
The Poms and Euros should consider ceiling fans.
Given the still low frequency of these events, that seems a logical move. Every old movie you see set in a tropical British/French colony has ceiling fans, so it's not like they don't know about them. I'd guess they were ubiquitous in sbooker's part of Australia.

Still, there's the humidity factor. I lived that summer 2020 in Florida, visited in November and April also. In that climate you need A/C 24/7 for something like 8 months a year and it will still be in use intermittently the other months. That applies now full time to World Cup visitors in Miami, Atlanta, Houston, Dallas, and most of the time in NYC and Philly.

The next World Cup at this time of year in Portugal, Spain and Morocco could be interesting weather wise with few if any domed stadiums. I wonder how the Miami games are doing with no A/C, unlike Atlanta, Houston and Dallas?
 
We have 2 systems

Are swamp coolers used in SoCal or is that more an inland/desert thing? Isn't the zone where you live considered a desert?

My recollection is that they're effective until the temperature outside is approx. 93F/34C. Once you're above that, AC is the only option.

Humidity around here in summer is usually 45-50%. I have not seen swamp coolers here aside from an auto mechanic garage. They work in very low humidity. Scotty's Castle in Death Valley had one but it was built 100+ years ago before A/C was used much. My cousin in Phoenix says they work during dry heat season up to mid-July but that they are not effective in later monsoon season.

But James may be right. My observation is that 93F/34C is the highest temperature I find comfortable in shade when humidity is very low. And I was in Phoenix in September when I made that observation. I don't Phoenix humidity goes up unless there is active weather.

I still don't understand split system, because Jason references it vs. ducted system which serves an entire house or al least one floor of a house. . Is split system just a different one room setup vs. the typical window unit? Window units are in windows so the exchanged hot air is vented to the outside. If you are only cooling one room, surely a split system is more expensive and if so how much more efficient is it to pay back that difference?

Our whole house system has only one zone, it was installed by the homes first owner..It cools the upstairs fine. Not so great downstairs..We put the second system in to supplement the central air.. The little wall mounted air handler cools and dehumidifies the air and cools the downstairs believe or not...Its almost silent and doesn't block a window..
