If civilization does collapse living alone in a shed in the countryside is the worst possible thing you can do so of course a lot of preppers plan to do exactly that. Catastrophe and war is a driver of urbanization for a reason.

Griffen posted:Can you give me any historical examples of this occuring? Most that I can think of indicate the opposite: fall of the Indus Valley civilization, contraction of the Uruk phenomenon, late bronze age collapse, Fall of the Western Roman Empire, plague of Justinian, the Black Death, the Mongol Invasion. They all decreased urban population and development, sometimes drastically for centuries after. I agree that living alone in the woods is a recipe for death, but living in a large city as the wheels come off the complicated system that supports it isn't much better. I think small, well connected communities are probably the best bet as they can be more self sufficient and flexible. If they have the right mentality that is. Well I would stick with modern examples such as Somalia.

occluded posted:edit: also corgies are the best dog; my fondest professional memory involves one being the Very Best of Dogs but that's a huge sidetrack even for this thread. Well there are larger or more active dogs that consume more and some smaller dogs like Pugs that emit a lot more methane but still, in terms of climate change, it may be a stretch to claim corgies are the best dog. Personality may pose challenges when we get to the "eat the rich" phase. Perhaps a small, non-gassy but very angry breed like a Chihuahua is a better bet.

Qtamo posted:I'm not an expert on geothermal, but wrt to questions about depth versus energy production, there's currently a project ongoing in Finland where they're building a pilot facility with a 6,5 kilometer well depth. At least at the time they were announcing the project it was supposed to be the deepest geothermal heat production plant in the world. They claim "up to 40 MW of energy" as the production. Finnish bedrock is pretty hard but also very stable, which I'd guess makes drilling a bit harder. They've currently finished drilling and the plant is supposed to start production in early 2022, so I guess we'll find out pretty soon how well it works in reality and what the actual production is. Denmark has it's first geothermal project in the works as well. Maersk used to run oil and gas rigs in the North Sea but sold it off and now wants to use that expertise to do geothermal. It's for district heating though. They're cagey about it but they're actively building infrastructure so it's more than a hypothetical.

I feel like opposition to nuclear is similar to opposition to GMOs and "chemicals" aa a more general opposition to the artificial. Similarly I often see people talking about cities as if they are environmental disasters while idealizing rural living and smallholding. Like there's this continent in environmental and climate circles that still labors under the misconception that we can live in harmony with nature. Out of the concrete jungle into nature, small and local production, harvesting the natural forces of wind and solar, sustainable, self-sufficient. Mainly self-sufficient in vegetables. It's a problematic mindset because 8 billion people - let alone 10-12 billion - can't possibly live in harmony with nature. This planet is, and has been for a while, a human habitat. Some places are still untouched but by and large the most fertile areas have been scoured of natural life in favor of agriculture, industry, homes and roads. There is no harmony or balance possible in this. This can only work with technology and we need to do it at large scales in a parallel artificial system that aims to use as little land and as few resources as possible. If you want to grow a vegetable patch and raise some chickens by all means but if the trade-off is that you're now driving 30 extra miles every time you want to go somewhere because you moved out of the city, you're probably not helping. It doesn't matter. We need nuclear and engineered crops and the efficiency of cities and every other bit of technology we can get to limit our footprint. It's not natural and there's no harmony because it's fundamentally unnatural for there to be this many of us and for us to live this way.

Crosby B. Alfred posted:
It affects all farmers whether they grow 50 or a 1000 acres. It reduces yield per acre which obviously impacts them financially so of course some are upset. While fertlizers are critical and irreplaceable in our food system they are subject to diminishing returns and have environmental costs so for wider society it makes sense to optimize tradeoffs. Agriculture is economically irrelevant in most modern economies and Europe has good food security so chosing to reduce food production to limit environmental damage is a viable option but obviously it's unpleasant for farmers.

A big flaming stink posted:Not quite, my concern is that satisfaction with the IRA, and consequently the Paris accords, shows a complete disregard for the global south. The complete success of the Paris Accord will not avert a rise in temperature that will, unquestionably, subject the global South to unimaginable deprivation. Complete and utter destruction of their ways of life deprivations. There's nothing that will do that though. Climate Change has been ongoing for a century and the changes that are baked in will affect billions of people no matter what. No legislation or action we take will make that not true. We can make climate change less bad and that's it.

Electric Wrigglies posted:As someone that is part of reducing climate impact of the global south without loving over their lives with violence for their own good, I think you don't appreciate what tearing down all the systems actually means. Like a survivalist that thinks the post nuclear armageddon will include them as anything other than another corpse on the side of the road or in a tunnel, you and me both alongside anyone that knows about climate models will be put up against a wall and shot in a proper revolution. It makes sense if you think humanity is fundamentally good but has been corrupted and controlled by capitalism. We just have to break the system and set humans free to work together and solve the problem. It relies on the assumption that the masses would want to make drastic personal change and sacrifice for absttact long-term benefits if only they were allowed to. I think humans are just kinda lovely. Greed and short-sighted self-centered pricks predates capitalism - the Pyramids were not built for the sake of capital gains or tax breaks. If we somehow peacefully smashed the system it's not obvious that the result would be popular demand for austere living rather than groups competing for as large a cut as possible at the expense of each other. Which is what we do now.

Enjoy posted:Basically go vegan or stop posting Sure but it's still less than 6% of emissions. We can't reasonably get rid of all of it. There's good reason why subsidence farmers in underdeveloped regions all have a few pigs, goats or chickens - it's an efficient use of household waste. We could limit it but it would never be a 6% emission reduction. The main emission culprits are buildings and road transport. In industry it's steel and cement. In agriculture I'd hazard that it's synthetic fertilizer and the whole sector would instantly become greener if green hydrogen could replace grey hydrogen.

slurm posted:If everyone followed my example we'd be at zero human emissions in, at most, a decade. If we all followed the example of Ethiopians the US would be at 0.6% emissions which would be adequate. What is your aim? Do you want to reduce emissions to reduce climate change impacts or do you believe it is a lost cause and you're just living your best life until the end? If it's the former then subsistence farming and avoiding all modern technology and conveniences is fine. It's a dull and umpleasant life but it's not difficult. If it's the latter then why do you care if others are living their best lives in a different way? I think you made a choice to kill yourself rather than reduce your standard of living and now you want to guilt trip parents for having carbon emitting children so you can pretend that your choice to have a big end of the world carbon emission party is morally superior.

The European Union is working on a carbon tax tariff scheme. Financial Times did a piece on it.Financial Times posted:EU’s trading partners accuse bloc of protectionism over carbon tax plan Policy wise it appears to have much the same aims as the US Inflation Reduction Act but with diametrically opposite approaches. The US is spending massively on the energy transition while the EU is forcing industry to transition through taxes. The EU is complaining that the US is unfairly subsidizing domestic production while the US is complaining that the EU is unfairly taxing imports. In both cases onshoring industry and a degree of deglobalization seems more of an intended feature than a bug.

cat botherer posted:DAC is a pseudo-technology to fool the rubes. It's a complete pipe dream and doesn't make sense from basic physics. CCS from emission sources isn't complete bullshit but it is absolutely being pushed for cynical reasons. Again, you are confusing this whole situation by continuing to conflate these things. You could use surplus nuclear for steam reforming natgas to hydrogen which would probably be cheaper than electrolysis. You just need to put the carbon somewhere... DAC makes little sense to me as long as there's literally anything else electricity can be used for.

Well define "meaningfully". You could argue it doesn't make a meaningful difference to cure 1 child of a given disease if 99 other children can't be cured. I would argue that anything that makes a positive difference is worth doing whether or not other, better options exist or it is meaningful or sufficient or adequate etc by whatever preferred arbitrary definition.

bird food bathtub posted:Nothing in electrifying vehicles is going to the root of the problem and saying "Burning dead dinosaurs is going to kill everything, you need to stop it". Eliminating internal combustion engines, which is what burns oil, seems like a good way to stop burning oil. The remainder of oil consumption is essentially plastic and I don't think plastic consumption is held back by cost or could realistically grow enough to pick up the slack. In any case it's a lot easier to ban oil if the cost to the average person is to do without cheap consumer plastics and not suddenly being stranded in the suburbs without transport.

Adenoid Dan posted:Greenwashing is doing PR and making small investments that make people think your company is greener than it is. For example, going to a fossil fuel funded institute to talk about how the engines you make will be hydrogen powered by 2050 I suppose they could wait to make hydrogen vehicles until the hydrogen sector has been transitioned to green sources but it's not obvious how that would be beneficial. Surely getting the technology developed and in place so there's a demand for green hydrogen is better than just burning diesel until some arbitrary threshold where a sufficient amount of hydrogen is green to no longer qualify as greenwashing. The European Commission has proposed to produce 10 million tonnes of renewable hydrogen by 2030 and to import 10 million tonnes by 2030.. Australia also keeps talking about becoming a hydrogen exporter and Saudi Arabia is actively positioning for it. To what extend green hydrogen will be used is an open question. We will absolutely need it for some things but how low the price will eventually go and its eventual limitations is still opaque. It's an entire industry and supply chain that is being bootstrapped right now.

Preen Dog posted:Only destructive degrowth and the right people suffering can motivate (even the possibility of) legit global sustainability consensus. The more, and sooner, the better. The drug is taken, the OD is certain, let's just hope the patient lives. You would have to convince people that destructive degrowth now will be better for their quality of life than the consequences of climate change later. I don't think blowing up infrastructure will get people to make that leap of logic - that's just forcing destructive degrowth on an unwilling populace.

I don't think capitalism is really the problem. There's this idea that capitalism is forcing us to behave in this way so if we just get rid of it we'll all be better. Personally I think our species is just kinda lovely. Technology enables our worst impulses and capitalism serves them but ultimately the issue is our values. People want to drive cars and live in houses and fly on vacation. I see no reason why we would stop wanting that just because our economic system is different. Across time and cultures humans have always desired material possessions and comfort. If we were a different species maybe we'd prefer to learn, experience or work less when we have accumulated excess wealth but mostly we just consume more. Perhaps a system of government which is not beholden to the wills of electorates which implies authoritarianism but even then you still rely on some support to stay in power so you would not, in fact, have unlimited power. In any case the people that end up on top could have any conceivable set of values.

cat botherer posted:The key to solve climate change is to endlessly nag people and focus on individual responsibility, and hope that billions of people spontaneously change their behaviors, irrespective of any material conditions or incentives they find themselves in. Companies such as BP are at the forefront of this fight, with innovative ideas such as getting people to calculate their "carbon footprint." Well if people don't think those behaviors are harmful then they won't support measures that will restrict them. If people are admired and idolized for living in giant mansions, driving hypercars and flying on weekend retreats you're going to be fighting a very uphill battle trying to tax or ban it. Sweeping dramatic societal changes needs a popular foundation. We can't just quietly smile and nod when people do these things and then turn around and say we need to ban cars or we'll probably all die. If we want to make changes in society then we need to first have the conversations that enable them.

Professor Beetus posted:Exactly, a means of fighting climate change that continues with largely the status quo of what spoiled American babies want will simply lead to the status quo of the world's poorest suffering under our boot. How noble of us to find a way to keep producing pointless wasteful garbage while the world burns around us and we take the rest of the world with us. You don't have to care about the standard of living of spoiled Americans but realize that the vast majority of Americans do care and you can't reduce their standard of living without some popular support regardless of the economic or political system you envision.
