my morning alarm sets off a radio and plays world news briefly so i can be sad as i greet the day, and i'm sure this has been discussed but in a piece about the G7 it was remarked the meeting "tackled" issues like poverty, violence, the war and climate change and i feel like i can't be the only one who wondered how each world leader like. got there. to the summit.

I'm not really bothered by leaders flying to their climate summits, it's a drop in the ocean really. At worst it provides a stick to critics to beat them with, and it's bad optics, but in reality it's just not a problem. Deals to solve climate change don't get done as it is, why make it even less likely with zoom meetings?

sorry, to be clear, i know it doesn't make a difference whatsoever. they could have used a private jet, each of them, one for each piece of luggage they carried, and it wouldn't matter. what's funny to me is that a) the climate was a footnote on this broadcast and b) there's something emblematic about world leaders taking massive private jets to go to a meeting to discuss how they can limply combat the inevitable while simultaneously discussing the economics of how to best pretend to do that while still appeasing various shareholders. started my day with a lmao if you will.

There's George Manbiot's "microconsumer bollocks" but this has to be in pico or femto territory. B.C. produces 90% of its electricity from hydroelectric dams. Due to the nature of the North American electricity market at certain periods of the day it's cheaper to idle some of the generators and buy electricity from other regions, saving the water for when the price spikes again. We don't actually have time of day pricing for electricity but if you own an EV and program it to recharge during low demand periods because you want to feel like a responsible citizen there's a definite chance you're buying electricity from Alberta at 60% coal power.

Like any savings you see from this have already been spent by the company pushing this, is my thinking. usually companies are absolutely loath to count the emissions from the use of their products as part of their own emissions. like for example, when chevron says their carbon footprint is X, they're excluding the carbon emitted from burning the fuels they produce they consider that part of the user's emissions footprint. honestly doing demand/emissions response is good and should be mandated by the government for absolutely everything possible, but of course since apple has the easiest market sector to do it in, they do it by themselves for the eco cred.

People HATE it when you tell them that their ecological virtue signaling is actually pointless. Like turning off your lights: who loving cares anymore? people who want to save the environment and are "concerned" about global warming care and will remind you to turn the lights off, "don't you know how much electricity you are saving??" Yes. I do know. It's not much. Maybe back when lightbulbs used up 100W each it was a big deal, but modern LED bulbs use like 5W. If you had a light on for 24 hours it uses up as much electricity as an electric car driving 700 yards. Only nerds know how much power anything uses though and can do simple arithmetic, so we're going to do pointless things and pretend they are meaningful until we die.

Heh, "this'll be an issue in the coming decades." More like, in this decade. Sooner rather than later. I remember one of the plots from Deep Space 9 involved a Bond-style supervillain building a lair on top of Mount Everest and flooding the entire world save for the very top of the summit. Looking forward to mountain chalets becoming mountain fortresses. And to borrow from In Time, aside from water access, the best place to build will be at higher elevations - for the marginally better air quality. I'm sure a ton of urban areas are already well over 1000ppm in CO2 levels most of the year.

I've studied El Nino for many years, and it's really taken me a long time to synthesize these points in ways people can hopefully understand. You guys have been so good to me for so many years it's really the least I can do <3 And yes, you basically have it! Let's bring it home! All of the info I've discussed plus a little more to really give the full picture. This is my last effort post unless something changes. ---------------- Earth receives most of its incoming heat at the equator, which heavily warms the waters there. If nothing else happened, the equator would be more or less equally heated across the entire thing, right? But the earth rotates, which makes things interesting. The earth's rotation creates the trade winds over the hottest (most energy rich) ocean waters in the world.  These trade winds push warm water west, where they encounter land masses that pile the water up:  You might be asking, why the other oceans don't built heat in the same way? Why don't they have pronounced warm pools on the western end of the equatorial oceans in the Indian and Atlantic oceans? Well, that has to do with the size of the oceans. The Pacific is incredibly vast. Therefore it has the most space to collect warm water. This is a simplification, and the Atlantic kinda does a mini version, but that's getting into the weeds. El Nino is basically the pressure release valve for the West Pacific Warm Pool, which is the biggest warm pool in the entire world. For a rough comparison, think of a hot water kettle; it warms until a certain point, then begins ejecting steam. El Nino is kinda like this; El Nino is broadly speaking, a pressure release valve on the system. For example, warm water displaces more space than cold water. This makes the ocean literally higher in the West Pacific and lower in the East Pacific:  This is incredibly unintuitive. I think if you asked a random person if the ocean was higher in some places than others, they would laugh. But it's not just true, it's so true that we can actually use satellites to measure the height differences, and use that as a proxy for the overall heat in that section of water, which is really loving cool if you ask me. Check this poo poo out:  That's a map of water heights! So cool. It's constantly changing of course. This is just a rough map of 1992 and I don't even know that it's correct but you can at least see the dynamics at play, so it's worth understanding.Anyways- imagine if this water kept piling up? The more the water piles up, the more force is exerted on the system to rebalance. This should be intuitive; what comes up must come down, no? So, the trade winds will always keep piling up water. After all, the globe will always rotate (it actually rotates faster and slower depending on various factors but that is beyond the scope of this discussion). El Nino causes the earth to rotate slower, which is pretty dope but doesn't have much to do with our talk here today. At a certain point, the overall factors in the system will drive an attempt to "blow off some steam" which is, on a basic level, what El Nino constitutes. This is also why La Nina almost always follows El Nino; after El Nino the system is off balance in the other direction, which simply re-establishes trade winds (La Nina is not the opposite of El Nino, it is just an aggrivated push towards resuming normal trade functions) The West Pacific Warm Pool is so large, and therefore such a container of heat energy, that its displacement alters the function of the entire ocean/atmospheric system. It changes the entire system of air circulation:  ^ This is an important image. Things you need to know, and I'm trying to keep this light on details. Air circulation is a big rectangle and the most dominant part of the circulation creates the rest of the circulation. This is somewhat technical, sorry, but the end results are easy to understand: A) The UPLIFT part of the cell is because of convective energy (you can see in this image, it's creating rainfall above it!). You can see that the Warm Pool creates a near-permanent uplift branch in the far West Pacific. This is because the warm water convects upwards. B) The moisture/energy-laden air is then moved Eastward over the Pacific. But it eventually falls DOWNARD, because a loop like this must always have upwards and downward components to make a circulation, right? This happens in the far East Pacific, where the USA is, because the trades move all the warm water west, leaving the water in the East Pacific cold as poo poo. Downward moving air stifles storm formation and is associated with higher pressure. The image I posted is so important that I'm going to post it again: You see what's happening there? The entire circulation is changed. The upward and downward branches of the circulation are switched!! The West Pacific cedes its dominant, uplift status to the East Pacific. That uplift branch then juices the poo poo out of the jet stream above it, which highly impacts North America. It moves the jet south, juices it up, and we get the canonical El Nino event. The jet stream is strengthened by the area south of it on the equator, this is called the Equatorial Bridge and you can see it in action here:  So in a nutshell, what is happening in an El Nino? 1) The West Pacific warm pool gets incredibly warm due to trade winds operating normally. 2) The system eventually can't sustain its own operations and pressure releases, throwing packets of warm water eastward over time. 3) These packets form a warm pool of water in the East Pacific. If strong enough, this warm water establishes a Feedback Loop wherein more warm water is continually moving east. An El Nino is formed! 4) The atmosphere couples to these water temp changes, changing the circulation to favor convective uplift / enhanced storminess / more energy into the jet stream directly above it, which means the jet stream is boosted right into North America. 5) This persists until, usually, the following spring, where the trades resume and the warm water is again funneled to the West Pacific and the cycle begins again. This coupling between atmosphere and ocean is integral. El Nino's full name is ENSO: The El Nino Southern Oscillation. The coupling of water and atmosphere to create a complex change to the entire workings of the system, and ultimately having profound effects on the entire world. Sometimes, just one part of the system tries to couple- maybe one year the warm pool is has a lot of latent energy to move east, but the atmosphere isn't playing ball. Or the atmosphere is trying to move warm water east but the ocean isn't playing ball. ENSO needs a full coupling of both systems, strongly, to really present its "canonical" historic far East Pacific presentation. Anyways that's it, cheers. Mayor Dave posted:Speaking of Yep. This region is in MAJOR trouble. El Nino stifles the monsoonal system in India, which is what the region relies on for temperature control and rain. It's scary to think about how this system will look in actual winter when El Nino is in full force. Pakistan looking horrible too. There is still time for El Nino to collapse though... but I don't personally think it will. We had 3 years of La Nina before this; the pressure to create a strong El Nino is incredibly high. Like I said before, I am very worried about the next 12 months. A strong El Nino would push forward global warming significantly. I tend to believe that we are underestimating climate change. This is highly speculative but I think we will see intense displacement events, causing worldwide reshuffling of humans, far before people estimate. I hope I'm wrong. We decided not to have kids for several reasons including the climate; if you do have kids this is extremely important to you, and you should be following these trends VERY closely. Have a rainy day fund if you can. Have a plan; well before people must move northward, enough will that housing and resources in those areas will be increasingly expensive. They will lock the doors and draw up the ladder. Just a question of when. Be safe out there. I've said this before but America is full of essentially 3rd world people who are one paycheck away from destitution. And I think it's pretty clear that at some point the government is going to treat these people the same way they treat climate refugees from, for example, Central America. It's horrifying but here we are. That goes doubly for anyone in the "you're hosed" areas like Florida... Texas... the desert SW... basically where everyone is currently immigrating to! That owns! We definitely shouldn't have allowed that! lol Taima has issued a correction as of 10:34 on May 23, 2023 |
