El Niño is coming. The last time ocean temp. looked like this, millions died
- ath3nd 5mo agoThe seriousness of whats written is drowned in the fact that its written by AI.
- manytimesfail 5mo agoThese "but it's ai" responses are boring. This doesn't read as an AI generated post. It provides concise, useful, source-backed information to communicate an important point. Who caresssssss....

- xvxvx 5mo agoThere’s been so much climate alarmism since Al Gore decided to pivot to ‘hero of humanity’ that it barely registers for me now. I still have frozen rice and beans from covid. Hope they’re still good.
- amanaplanacanal 5mo agoIf you are a rich Westerner, you'll probably be fine. It's the poor that take the brunt when these sorts of emergencies happen.
- ResPublica 5mo agoExactly
- adampunk 5mo agoNo one is going to be fine.
- caminante 5mo ago>rich Westerner Not quite. These affluent countries torture themselves with terrible energy transition projects that jack up prices for everyone at the cost of more efficient alternatives. Healthcare, nutrition, education and other programs do vastly more for quality of life improvements for the poor.
- amanaplanacanal 5mo agoWe aren't doing those either.
- caminante 4mo agoYeah...I know you want to gripe, but you'll have to be more convincing.
- AngryData 5mo agoIs it really alarmism when anyone alive for the last 30 years can clearly tell weather patterns are changing? To me this is like claiming someone in 1901 was an alarmist for talking about how dumping chemicals into our waterways was destroying them and dumping chemicals out the back of plants was creating polluted toxic ground as they observe increasing numbers of dead fish. And they were right, there are endless numbers of extremely toxic superfund sites and even more that are poorly documented that we know are killing people.
- littlexsparkee 5mo agoI'm as big a doomer (realist?) as they come but I think the framing is misleading here - deaths due to natural disasters have gone down due to planning, infastructure, coordination, better warning systems, so merely stating that millions died last time feels like sensationalism
- caminante 5mo agoYou really should revisit the absurd claims Gore was promoting that didn't age well like the north pole melting in 5 years (2014). IMHO, the toxic chemicals comparison doesn't work. For climate change, you have alternatives to raise people's quality of life more effectively and saying that you must prioritize fighting climate change over ... better healthcare, sanitation (avoidance of toxic chemicals!*), nutrition, workforce development, etc. is not really an easy sell because the other paths yield better ROI. *Edit*
- defrost 5mo ago> You really should revisit the absurd claims Gore was promoting Why? Absurd claims are absurd claims - I have zero doubts about the AGW outline and majority of case and data put forward in the IPCC papers despite never having seen the Gore film nor even living in the USofA.
- delichon 5mo ago> I have zero doubts That is a red flag, regarding almost anything. It's a blind spot.

- h4kunamata 5mo agoThere is way too much noise, AI made what was bad worse. Before, it was the main stream media sharing biased information. Now we have the same biased media AND AI sharing slope left and right. The only option left is independent journalist, ignore everything else.
- breakyerself 5mo agoThe earth is hotter than it's been in 125,000 years. Warming at a rate dozens of times faster than the fastest periods of natural warming. The oceans are 25% more acidic. The worlds ice sheets and glaciers are losing 1 trillion tons of mass per year. Did Al Gore make a stupid prediction about arctic sea ice loss? Yes. Do you know who criticized him at the time? Climate scientists. Did you know Al Gore isn't a fucking scientist? I fucking hate Al Gore. You know why? Because he made himself the face of the climate crisis and now every partisan fuck on the right can't see past that. It's overwhelming their rationality.
- insane_dreamer 5mo agothis reaction is a big part of the problem also has nothing to do with possible covid food shortages
- orwin 5mo agoThere were so much alarmism in 1898 against opioids in children's cough syrups, it barely registered. Then politicians decided to ban it for a few thousand dead, when alarmist doctors talked about millions.

- psb5 5mo agoJust imagine how much energy is required to produce that band at planetary scale.
- defrost 5mo agoI'm imagining it as incremental amounts of a tiny fraction of the amount of energy that arrives daily on the planet from the sun. I'm guessing the amount of energy is less of an issue than the cascading transformation chains the daily solar energy allocation bounces through, less of an issue than increasing insulation factors in the atmosphere, etc. Would that be about right by your reckoning?
- psb5 5mo agoWell I was just thinking about how much time and energy it takes to warm a large building. This system is warming things up for thousands of miles. It probably makes what the entire grid consumes look microscopic.
- defrost 5mo agoHaving a building heating amount as a base unit is likely an error of scale - not incorrect, just not particularly useful or enlightening when it comes to making a model of energy flows and cascades about the planet. > It probably makes what the entire grid consumes look microscopic. The entire US grid? Entire global electricity grid? Probably? Have a shot at putting numbers and units to some of this ... Total amount of daily solar energy fall, total amount of daily energy radiation to space, daily residual energy at sea / surface layer, historic and current human energy consumption (broken into electricity, heat, ??) etc. It's a handy exercise.
- burnt-resistor 5mo agoThe Sun imparts about 7.6 kWh/m²/day at the equator. Suppose the area of the equatorial oceans is about 100M km². That's 2.41e21 J/day potential of hitting oceans, but not entirely absorbed. Put another way: about ⅓ the energy of all natural gas reserves as solar radiation per day.
- delichon 5mo agoI'm living in a New Mexico forest that is full of dead pinyon pine trees after a beetle blight caused by a long term drought. The wildfire danger is extreme. A super El Nino would be an answer to our prayers. I wouldn't choose it at the cost of millions dead, but for us it would be a gift from above. Not a pardon, but maybe a reprieve.
- mordechai9000 5mo agoMy concern is that even if it would temporarily alleviate the local drought conditions for some areas, it wouldn't reverse the long term trends towards hotter, drier conditions.
- dlcarrier 5mo agoI have a family member that works in the field, and it's pretty crazy how little attention we pay to weather extremes. Not only do we not plan on dry years, we also don't plant on wet years. We tend to make very optimistic views of weather cycles, then plan for best. Where he works in California, a large portion of the total rainfall occurs during El Niño cycles, which means once a decade or so, they'll get a year or two with several times the rainfall of the other years in the rest of decade. They take the average of the whole decade, and plan that as the baseline. This means that under normal weather cycles, they expect most years to be far wetter than data shows they will be, and the remaining years are treated as extreme rainfall, despite it being regular and predictable. On top of that, they only have ~200 years of data, but most of the data points only cover half that time. They use the newer data to create their models, because it has more data points, despite knowing the whether was much worse in some of the earlier data, with extremes like a hurricane that hit San Diego in 1858 and the worst-ever-recorded flood in 1862. The only way to handle weather extremes is to design around future expected variations when building infrastructure. Whether we tried to use all of humanities resources to change course, or there were no anthropogenic effects at all on the climate, the glaciers would be melting and lakes would be drying up. There's nothing we can do to control these weather extremes in any meaningful way, but we are pretty good at figuring out what extremes to expect. To put in in perspective, in the Late Pleistocene era, glaciers covered almost the entire US/Canada boarder and all of the great lakes, but California, Nevada, and Utah had their own great lakes. At the other extreme, before that ice age started, there was liquid ocean at the North Pole. This cycle occurs over hundreds of thousands of years, so infrastructure for any given lifetime needn't be planned around it. At the other end, we also have weather cycles that occur multiple times within the design life of any given piece of infrastructure, and we should design for those.
- zaps 5mo agoStupid question: how do they know with such fidelity what the water temp was in the Pacific in 1877? It’s not like solid land where there are strata and whatnot that leave a geological record? Or is it?
- f33d5173 5mo agoIt wasn't that long ago. Maybe someone stuck a thermometer down there.
- AnimalMuppet 5mo agoOver enough of the Pacific to be able to say this with confidence? They might have... but I doubt it.
- ssl-3 5mo agoOceanic science has has been happening for quite a long time. You may wish to have a look at this: https://en.wikipedia.org/wiki/European_and_American_voyages_of_scientific_exploration https://en.wikipedia.org/wiki/European_and_American_voyages_...
- AnimalMuppet 5mo agocntrl-f temperature: zero matches. cntrl-f therm: zero matches. I know voyages have been done for a long time. There weren't many undiscovered islands by then. There were a bunch of species found (my ancestor did a fair amount of that). But how good was the temperature map? How do they know what the water temperature was, across the whole Pacific, in 1877? At what resolution do they know it? dlcarrier's answer (at https://news.ycombinator.com/item?id=48202959 https://news.ycombinator.com/item?id=48202959) says that they are using the data that they do have to derive the temperature, with "more precision than accuracy". They don't know that accurately, and what they do know, they don't know from "someone sticking a thermometer down there".

- wavemode 5mo ago> NOAA has now placed the probability of a Super El Niño forming by winter at over 95%. This claim appears to be false. According to this article's own source, the probability of an El Niño of any severity forming is over 95%, but there is still "substantial uncertainty" about what that severity is going to be. https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.shtml https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/e...
- burnt-resistor 5mo agoBtw, 100 years of forest fire elimination has left old growth trees vulnerable to death by scorching when forest fires do come through. The answer is a difficult one: for humans to move flammable litter away from the trunks of old growth trees manually; inconveniently, Rake America Great Again is partially correct, unintentionally. It's a problem that humans have created that nature cannot fix itself.
