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

Before you do that, do the cost effective thing: shadow and wind. Then you can add an aircon iff thats not enough.
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.

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.

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.

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.

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?
thyristan 1 hours ago [-]
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.
dom96 36 minutes ago [-]
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?
spockz 3 minutes ago [-]
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.

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.

Growth trend matters more than absolute present value.
Data centres generally had been seeing energy use growing at 12% annually, or with a doubling time of 5.8 years (about 5 years 10 months). AI is accelerating that trend.
In the United States, power consumption by data centres is on course to account for almost half of the growth in electricity demand between now and 2030. Driven by AI use, the US economy is set to consume more electricity in 2030 for processing data than for manufacturing all energy-intensive goods combined, including aluminium, steel, cement and chemicals. In advanced economies more broadly, data centres are projected to drive more than 20% of the growth in electricity demand between now and 2030, putting the power sector in those economies back on a growth footing after years of stagnating or declining demand in many of them.
DC water consumption is a red herring. That water is returned back to its source but warmer.

In your mind this is a closed loop system of clean water. It is not. And as DCs have less and less discharge there is more and more solid waste produced.
Your assertion that "water consumption is a red herring" is utter bull shit. I'd suggest enlightening yourself [0][1][2][3].
Due to the widespread idea that climate prediction has been predicting doom and gloom all the time, and has always been wrong about it, I have been entertaining myself by revisiting old climate predictions from 20 years ago. I can highly recommend it.
I mean, predicting the climate must be one of the hardest numerical simulations you can run. Climate models are famously incomplete. But the results turned out to be way more accurate than I would have thought. That's some impressive modeling, and I would assume that models have only improved since then.
The most chilling thing (and not in a good way) about it is that popular science type repotrs for the general public usually indicate an interval between a good case and a bad case, with a nice line in between. In retrospect we have been pretty much perfectly tracking the bad case line ever since.

I wrote to Alan Kay over 8 years ago about my fears of global warming and how tech seems to dismiss it as a concern on the whole.
A little known fact about Alan Kay is over 20 years ago he was part of a group of "systems people" who published for the NFS about various systems including the climate. He helped write "Transitions and Tipping Points in Complex Environmental Systems" (https://nsf-gov-resources.nsf.gov/2022-12/Transitions-and-ti...). He wrote to me that "This, along with many other warnings from many other sources over many years, fell on deaf or disbelieving ears."
He agreed with my concern saying "And, yes, you are right that things will likely be really bad if the climate is allowed to crash past the tipping point."
But what he said following that shook me to my core. Kay said "If you think of a system as an upside-down coca cola bottle, it is easy to see that a little nudge can topple it, whereas considerably more energy is then required to put it back.".
What this means is to get CO2 back down to 350 ppm (we are at 428 ppm), we would need to expend more energy than we did getting it to 450 ppm. That means, we would have to expend more energy that humans have produced IN ALL OF HUMAN HISTORY in the next 10-20 years just to put the system back to where it's safe. Thermal dynamics and entropy do not play games.
Ask yourself, where are we spending our energy right now as a species? On putting the system to a safe level or something else?

Most of the most flood prone areas in CA have been significantly neutered over the decades thanks to massive water projects. There was a time when the LA river would destroy LA routinely. Now everything is channelized. At risk communities are probably the handful of remote ones that do not have great infrastructure, but I'm not even sure where those might be given how the state seems to be able to build thousands of debris flow cement storm drain setups in relevant areas.
Other states seem a lot worse off. Water table is closer to where people live, there's a lack of topology to actually run water out in a lot of cases, there's been little investment in managing water for stormwater for property damage abatement or power or irrigation like in CA where the topology really incentivized massive investment in all of that over the last century.

It's bad that such dramatic climate change is happening, but we're definetly lucky to live in the West Coast because we won't face the brunt of some of the worst aspects of the El Niño comparatively and have the infrastructure to deal with it.

Also, most of our infra is state funded which gives us a lot of leeway.

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.
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 last time earth will have been as hot as the 3C temperature was prehistorically.
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.

We are entering uncharted waters and I fear that at some point we will get an extreme extreme weather event and the worse thing is that we won't see it coming.
That core problem won't end this year or the next one, and it will keep disrupting global climate. And with it, agriculture, settlements, economy and civilization as we know it.
And the scariest part is what we do about it. Keep doing activities that rise global temperature and power up positive feedback loops, weakening or abolishing climate policies, and when things start to feel urgent will try things by the fast way with unclear outcomes.
What do you mean we are doing very little?
Except those guys throwing soup at the fossil fuel HQs. They did a little.
So we're doing something, but those things are counterproductive to our planet's general well being. Apparently billionaires don't need an inhabitable Earth to live on.
AI data centers are what, half a percent of the world electricity consumption, if that, and an even smaller fraction of the total energy?
Data centres generally had been seeing energy use growing at 12% annually, or with a doubling time of 5.8 years (about 5 years 10 months). AI is accelerating that trend.
In the United States, power consumption by data centres is on course to account for almost half of the growth in electricity demand between now and 2030. Driven by AI use, the US economy is set to consume more electricity in 2030 for processing data than for manufacturing all energy-intensive goods combined, including aluminium, steel, cement and chemicals. In advanced economies more broadly, data centres are projected to drive more than 20% of the growth in electricity demand between now and 2030, putting the power sector in those economies back on a growth footing after years of stagnating or declining demand in many of them.

Colossus 1 and 2 still use open loop systems. And with the case of blow down water that's "returned" it's not usable due to the use of concentrated salts (1,200 to 6,000 mg/L).
In your mind this is a closed loop system of clean water. It is not. And as DCs have less and less discharge there is more and more solid waste produced.
Your assertion that "water consumption is a red herring" is utter bull shit. I'd suggest enlightening yourself [0][1][2][3].

I mean, predicting the climate must be one of the hardest numerical simulations you can run. Climate models are famously incomplete. But the results turned out to be way more accurate than I would have thought. That's some impressive modeling, and I would assume that models have only improved since then.
The most chilling thing (and not in a good way) about it is that popular science type repotrs for the general public usually indicate an interval between a good case and a bad case, with a nice line in between. In retrospect we have been pretty much perfectly tracking the bad case line ever since.
We're pushing ourselves into absolutely untold suffering the longer do nothing. I truly fear a famine like that and the more we go down this road, the closer we're getting.
Obviously its too late to avoid the worst, the only hope we have is to collectively cooperate to help each other get through it. Not sure that will happen but I believe that's the only way through.
So the answer to your question is it could be either or both or neither. Whatever happens is going to be on average more extreme than what you're used to.
So get some sturdy shade structure and an heat pump.
No need to fix the root cause, I’ll just fly somewhere cold during the summer /s
A little known fact about Alan Kay is over 20 years ago he was part of a group of "systems people" who published for the NFS about various systems including the climate. He helped write "Transitions and Tipping Points in Complex Environmental Systems" (https://nsf-gov-resources.nsf.gov/2022-12/Transitions-and-ti...). He wrote to me that "This, along with many other warnings from many other sources over many years, fell on deaf or disbelieving ears."
He agreed with my concern saying "And, yes, you are right that things will likely be really bad if the climate is allowed to crash past the tipping point."
But what he said following that shook me to my core. Kay said "If you think of a system as an upside-down coca cola bottle, it is easy to see that a little nudge can topple it, whereas considerably more energy is then required to put it back.".
What this means is to get CO2 back down to 350 ppm (we are at 428 ppm), we would need to expend more energy than we did getting it to 450 ppm. That means, we would have to expend more energy that humans have produced IN ALL OF HUMAN HISTORY in the next 10-20 years just to put the system back to where it's safe. Thermal dynamics and entropy do not play games.
Ask yourself, where are we spending our energy right now as a species? On putting the system to a safe level or something else?
Other states seem a lot worse off. Water table is closer to where people live, there's a lack of topology to actually run water out in a lot of cases, there's been little investment in managing water for stormwater for property damage abatement or power or irrigation like in CA where the topology really incentivized massive investment in all of that over the last century.
Next year a super bloom then the following year massive wild fires.
rain -> fuel -> fire
We also have one of the more advanced waterwork system in the US to support Central Valley agriculture, so a lot of the worst aspects can be somewhat managed.
It's bad that such dramatic climate change is happening, but we're definetly lucky to live in the West Coast because we won't face the brunt of some of the worst aspects of the El Niño comparatively and have the infrastructure to deal with it.
Sadly, the brunt of climate change will be felt by the poorer half of the world.
The Lima Prieta Quake and the 1990s floods led to a lot of future proofing in Californian infra. The last major thing left is transmission weathering, which PGE and Sac are fighting over.
Also, most of our infra is state funded which gives us a lot of leeway.
Like I said before, it's bad that we're in this position and it's only going to get worse, but we're in one of the better places that can survive these kinds of shifts.
I hope we have something more to show than dozens of to-do apps when our children and grandchildren ask which important things made the massive use of AI necessary.
You don't.
and because we've been doomed since the 70s
why are we so eager and unquestioning of the published narratives going to the length of censoring counter theories?
Not everything gets worse if the planet heats up a little more.
> widespread drought and famine in multiple countries, causing the death of more than 50 million people. Disasters associated with it include the Great Famine of 1876–1878 in India, the Grande Seca in Brazil, and the Northern Chinese Famine of 1876–1879.
He would first deport it a couple times.
The fact that you see record breaking more often than log of time implies a drift in one direction.
