Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Electric cars are there to save the automotive industry not the climate.

The solution is in redesigning cities to be dense, walkable, and focused on active and mass transit.

Don't forget the international shipping logistics. Container ships are literally the worst.

[–] Skyrmir 8 points 1 year ago (1 children)

Container ships are as clean as an electric train in kg/mile. They might use the nastiest fuel on the planet, but they also move an insane amount of mass. And their operators are motivated by doing it as cheaply as possible. So it's relatively simple to make them decide to be even cleaner.

Supply chains have become ridiculously complex, though. Like 20 years ago a cell phone manufacturer talked about how just about every piece of a phone was ultimately shipped back and forth across the Pacific about 6 times before being sold in the final product. As raw materials, as base components, as more complex components built from others, after branding, packaging, etc. And although perhaps more and more manufacturing has moved into Asia, I doubt the complexity has decreased or that any particular mind to this kind of waste has been designed into our system generally.

I'm sure there are things to fix about the container ships themselves, as others have pointed out. But another solution is simply to use them MUCH LESS!

Consumerism is a cultural problem, not a supply chain issue. Convince rich popular people to show off their frugality.

The answer to shorter supply chains is local resource exploitation. That means dirty mines and factories, or convincing China they don't really want money. Both of those are really hard to sell.

[–] [email protected] 0 points 1 year ago (1 children)

Consumerism is a cultural problem, not a supply chain issue.

It is both. Capitalism encourages supply chains to be formed based purely on metrics such as cost on the production side. Nothing is planned further than what will minimize the cost to the company, so that profit is maximized. While roughly the same amount of consumption is done by the working class in its consumptive capacity, this does lead to greater consumption and waste by corporations as part of the production process. When we take control of our workplaces, we will be much better able to account for and make rational decisions regarding such externalities.

And to some degree, it's also pointless to try to separate "culture" from "economics". They influence each other. People don't consume simply to consume, but because of the pressures put on us by the system. We drive not just to drive, but because we need to get to work and school, and because capitalists have destroyed our public transportation options. The reverse—our affect on the system of capitalism—is much less powerful these days, as we've allowed ourselves to become powerless and subjugated ourselves more and more to the class war. Certainly cultural elements will be necessary to overcome this, like building a culture of loyalty to one's fellow workers and the unions which empower us, and eschewing advertising's daily effects on our habits. But to imply it is "just cultural" is missing a lot.

[–] Skyrmir 1 points 1 year ago (1 children)

A worker controlled company will be just as profit focused, the only difference being who the profit benefits. It's not a fix for external costs.

Again, you're worried about the economics, not the culture and government. If you don't have a working culture, you're never going to have the economics you want.

[–] [email protected] 0 points 1 year ago* (last edited 1 year ago)

A worker controlled company will be just as profit focused

First off, you're wrong. Capitalist-owned companies have a mandate to grow due to the ever-increasing demand for return on investment, and those who control the company have no disincentive for the maximization of profit (this shit is as old as the field of economics itself, so you might want to read some leftist literature and catch up). Worker-owned organizations can choose to grow or not, as they wish. And they have built-in disincentives against the maximization of profit, as they are the ones who must labor to produce it, and they also must suffer the consequences of bigger and more complicated work environments. So while capitalist organizations will ALWAYS be forced to the limit, worker-owned companies have much more room to choose, and to consider factors like how their behavior affects their communities, their environment (externalities), and the rest of their quality of life.

Second, I wasn't talking about a single capitalist company. I was talking about a whole economy built around them (capitalism). That, by the way, inherently includes talking about government (the modern nation-state is built to protect, uphold, and enhance capitalism, for capitalists). And it also inherently is about culture, which as I already pointed out is influenced by economics every bit as much as the other way around (far more so, in fact).

Are they though? What is the alternative? No trade?

[–] Atom 5 points 1 year ago

Nuclear powered ships like the US Navy has used safely for decades. Wind/solar powered ships that have test beds in operation now. Global shipping emissions standards so they can't switch to bunker oil the second they hit international waters.

Cars aren't going anywhere. Achieveing a 20% reduction would be great, but people in developing countries are only now getting started with cars. The only choice: what kind of cars?

Public transport is good, the nearest city to where I live has free public transport (Tallinn, capital of Estonia) but people still use cars. Public transport cannot get everywhere.

I propose a few test cases: try transporting someone old and frail, or a sick child or pet. Go by public transport, walk 10 minutes to the stop, switch lines, wait, walk 5 minutes to the hospital / clinic. If the old person tires, you can't carry them. Now try the same route with 20 cm of snow on ground. Now try with ice on ground. Now try in a storm. If you have a car, you'll be starting it up (if you don't, you'll be asking a friend or hiring a cab).

The question will be "which type of car", "whose car" and "how often".

Also, there will always be people working in the other end of the city, or in the countryside (where cars are practically required since public transport may be miles and hours away). People often have to decide whether to move near their job or move near their relatives (moving is an big hassle, it is not always possible to sell / buy / rent when needed, property prices differ, moving into a rich neighbourhood may be unrealistic) or commute. Smarter planning may reduce the flow, but there will be a flow. And industries are hard to integrate into living districts.

The problem with redesigning cities is that they weren’t exactly built with the possibility of being redesigned in mind. You’re talking about a goal that is hundreds of years of incremental change away. Electric cars are part of the short term solution, but redesigning cities is a much much longer term solution.

[–] [email protected] 11 points 1 year ago* (last edited 1 year ago) (2 children)

Why hundreds of years? American and Canadian cities became car-dependent sprawls in the span of a few decades. A concerted effort to redesign them would not of course have results in months, but 10-20 years are enough to completely transform them.

Also, when we are talking "redesigning", don't imagine SimCity like buldozing and rebuilding. It can start with doing away with zoning regulations mandating single family homes everywhere, doing away with strict commercial/residential zoning, doing away with parking minimums and allowing people to sell off parking lots for development. Then couple this kind of libertarian-style deregulation, with socialistic-like public investment on public transit and amenities (that should be much cheaper for denser neighbourhoods). In the US and Canada, good public transit will probably mean trams and trolleys, or (sigh) buses. Finally, establish norms that require good cycling infrastructure on any new road being built and any old road being repaved. It won't be too long for change to happen.

Finally, one more thing: E-bikes and e-cargo-bikes, along with quick infrastructure fixes (e.g., blocking off some roads or blocking off one direction in stroads with islands to make them transit and bike-only) are a much much better stop-gap solution than electric cars. The vast majority of car trips are with only a single person. Why haul a few tonnes of steel and plastic around? Instead, ebikes need much smaller batteries, and cost only a fraction of the cost. They are fast, and comfortable and can cover larger distances and you don't need to be sweaty when you get there.

The problem is that the current trends reflect what people have wanted, if you want a change in the system then you need a clear cut plan, not just deregulation.

[–] [email protected] 3 points 1 year ago

It's not as if there are no people who have thought deeply of this. For example: https://www.strongtowns.org/

[–] [email protected] 3 points 1 year ago (1 children)

The deeper I look at them the more insane cars actually seem. I understand the usage of freight trucks and things like that but cars are genuinely wasteful in most senses.

[–] [email protected] 1 points 1 year ago (1 children)

In cities personal cars are terrible.

In rural areas they are vital.

[–] [email protected] 1 points 1 year ago

Agreed but, not always. Not every rural town in the world implies isolated homes. Besides if you look at it more as a principle and less of a rule, as town grows you invest in adding public transportation as needed. But yes the more rural a place is the more car dependent it's going to be, but that's not that bad, most rural places also have much less population so it also has a much smaller impact.

The Netherlands did it in about 30 years, and nowadays we have more knowledge on how to build efficient cities, it can be done.

The US is a different beast from European countries, sure, but it doesn't mean it's impossible or that changing would literally take centuries. And even if it did require hundreds of years, isn't that more a reason to start as soon as possible?

Electric cars are part of the short term solution

Electric cars aren't here to save the planet, they're are here to save the auto industry. The solution is ditching euclidian zoning and increasing bike lanes and public transport.

[–] postmateDumbass 1 points 1 year ago (1 children)

euclidian zoning

I think you should use 'cartesian zoning' unless you have a flat earth agenda.

[–] [email protected] 0 points 1 year ago* (last edited 1 year ago) (1 children)

That aside is both a nitpick (the curvature of Earth is small enough on the local scale of a city that the differences are negligible) and it is wrong, as cartesian coordinates are planar and aren't useful for accounting for spherical curvature. "Euclidean" and "cartesian" are basically synonyms for this purpose.

[–] postmateDumbass 1 points 1 year ago (1 children)

Euclidian geometry is used for things on a globe.

non-euclidian spaces are those that are not spherical. Such as a flat earth.

Caretesian means to exist in an X-Y plane. Such as a grid in a city. Seems closer to your seeming intent.

[–] [email protected] 0 points 1 year ago* (last edited 1 year ago)

non-euclidian spaces are those that are not spherical. Such as a flat earth.

This is incorrect. Euclidean geometry deals with planar geometry such as that which cartesian coordinates are used to describe. I mean, here's a quote from Wikipedia:

More generally, n Cartesian coordinates specify the point in an n-dimensional Euclidean space for any dimension n.

Spherical surfaces are even used as kind of the classical example of non-Euclidean geometry. For example, you can form a triangle along great circles on the surface of a sphere and have all three angles be right angles (90-90-90); something not possible in Euclidean/planer geometry. See the linked text.

No one is going to bike 15 miles for a dozen eggs, and no one is going to build a supermarket closer than that, and I'm nowhere near an extreme case. It will take more than a century to restructure the US away from individual vehicles, if it's done at an insanely fast pace.

Public transport relies on the value of having a public around the stops, or the ability to concentrate the public in crossroad areas. It's already too late for that in the US, and will take multiple generations of land transfer to fix it. The entire country was literally built on expansionism and isolationism. Fixing our cities is the easy part, and that alone will take more than all government expenditure ever, over half a century at the least. And that's assuming we don't go bankrupt simply supporting the retiring population we have right now, let alone additional expenditures.

[–] [email protected] 3 points 1 year ago (1 children)

Supermarkets would be replaced with multiple markets in walking distance after removing the zoning that excludes retail from being within walking distance of residential areas.

[–] Skyrmir 1 points 1 year ago (1 children)

No one is building shit within walking distance of nowhere. There's less than 200 people within 20 miles of me, and I've moved to a more crowded area. No market is going to fix that. The nearest zoning law is probably a hundred miles away. And supermarkets didn't defeat small stores because of zoning, it's because economies of scale are more efficient.

[–] [email protected] 2 points 1 year ago (1 children)

In rural areas where population is the issue and not zoning, that is true.

In any city with 10 thousand residents or more it tends to be the zoning that keeps stores from opening up in the suburbs and other new development. There they tend to go big becsuse they are far enough away that they might as well be big enough to draw from as far away as possible.

Most people live in the latter areas and that is what is being discussed.

[–] Skyrmir 0 points 1 year ago

They're talking about replacing cars with public transportation which is fucking ridiculous for the majority of the country due to low population density and large distances. There's no amount of zoning changes that are going to fix that. Also, creating walkable cities is a great goal, with zero chance of happening in the US. It would be asking home owners and businesses to throw away existing investments, or forcing them to. Guess how well either of those options is going to go over. Especially in an aging populace with nothing but investment income.

[–] [email protected] 1 points 1 year ago

Doable but rather ambitious I would imagine considering how much infrastructure is built to scale without the idea of modularity or portability in mind
