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.

Also a huge number of people in the US travel to places that are walkable:

  • Disney World
  • Las Vegas (The strip is anyway)
  • DC
  • NYC

car free community

cover photo shows both a car and parking lot

I'm just being pedantic but this just shows how ingrained cars are in modern society that even "car-free" communities need them

[–] QuikxSpec@lemmy.world 22 points 7 months ago (2 children)

Also Disney is not designed for public use. It’s built to extract as much money out of you without leaving their property.

[–] sanpedropeddler@sh.itjust.works 11 points 7 months ago (1 children)

The strip is designed for that as well

And yet people enjoy it.

Maybe we should build our city centers the same way then.

[–] set_secret@lemmy.world 9 points 7 months ago

tree free too apparently

[–] Gigasser@lemmy.world 9 points 7 months ago

Probably more accurate to say it's a car optional community? Or walkable community? Or even arcology?

[–] Evil_Shrubbery@lemm.ee 6 points 7 months ago* (last edited 7 months ago) (2 children)

Yeah, I agree with you. Being 100% without a car is hard in most cases.

And the answer I see is trains. For the amount of money that does into the car industry (+ multi lane roads, administration, maintenance, etc) we could have super fancy, comfy, fast, frequent, and cheap/free trains.

And people would have more mobility too, at a fraction of the cost and environmental damage.

[–] SinningStromgald@lemmy.world 8 points 7 months ago

Robust public transit is the obvious answer to ridding ourselves of the car menace. Now, I need a few hundred billion dollars to "lobby" this into existence.

[–] PP_BOY_@lemmy.world 6 points 7 months ago (3 children)

Trains for long distance + trolleys and subways for local travel. There will invariably be people whose transportation needs require a private vehicle but this combo alone would clear up the majority of cars on the road in my opinion.

[–] Evil_Shrubbery@lemm.ee 8 points 7 months ago

Yes, exactly this.

I would love all city roads to look like this (but non-monoculture, have some flowers):

[–] nickhammes@lemmy.world 5 points 7 months ago (1 children)

Even in countries with pretty good public transit like the UK and Germany, a large majority of families have a private vehicle. If we had better trains and subways in the US, I don't think too many people would sell their cars, but only use them once or twice a week, rather than once or twice a day.

That's a huge win in my book.

[–] scrooge101@lemmy.ml 2 points 7 months ago (1 children)

UK and Germany don't have good public transport, maybe except for individual cities. Switzerland on the other hand has good and frequent public transport nationwide.

[–] nickhammes@lemmy.world 2 points 7 months ago

As an American who has experienced Deutsche Bahn, National Rail, and Amtrak, I'll stand by Germany and the UK having pretty good inter-city rail compared to us. Lübeck and Bath are the cities there I've been with the worst public transit, and they would be well above average in the US.

I haven't been to Switzerland yet, but it's not shocking to hear the public transit there is all-around better.

[–] Riven@lemmy.dbzer0.com 2 points 7 months ago

The trains in Japans greater Tokyo area were amazing when I went to visit. 99 percent of the time they took like 3 or 4 minites more than taking a car and I didn't need tk worry about parking or driving.

[–] doctorcrimson@lemmy.today 1 points 7 months ago

If it's the place I think it is then it's also located directly off the highway without really any nearby restaurants.

not gonna catch on as long as its sold with a price premium instead of a discount for what they save on not building and maintaining car infrastructure.

[–] Nugget@lemm.ee 8 points 7 months ago

The rents are extremely reasonable for the area. Here's a video where some residents discuss their rents: https://youtu.be/hf0L3blkNA4

Ohh yeah the popular and highly desirable thing that people are willing to pay a premium for won't catch on!

[–] Evil_Shrubbery@lemm.ee 8 points 7 months ago* (last edited 7 months ago) (4 children)

Why is the architecture and placement so bad tho? And narrow. Seems like a poor southern Italian village, but uglier. Or like a dark futuristic movie set.

Open walkable spaces can be pretty, does wonders for (populations) mental health.

[–] BossDj@lemm.ee 10 points 7 months ago (2 children)

The answer is to create shade. At those angles, you can find shade at any given time.

This is in frigging Phoenix Arizona. Nothing is walkable in 120 degrees.

Phoenix has a couple of these self contained communities already. The parking lot could be for people outside the community to come and visit the shops.

[–] livus@kbin.social 6 points 7 months ago* (last edited 7 months ago) (1 children)

That's like 48°C, pretty hot! I don't think I could walk around in that. I take back some of my criticism.

Surely they need trees and covered areas though, not just boxy houses jammed in together like crooked teeth.

[–] BossDj@lemm.ee 4 points 7 months ago (2 children)

This part is my speculation, but the tightness, aside from shade, might be to give the illusion of small community solitude from the inside. Tempe is a very built -out city. More open, and you'll be looking at all the typical American sprawl bullshit and probably a freeway or two

[–] livus@kbin.social 3 points 7 months ago

@BossDj interesting hypothesis. I've never been to that part of the world, but your theory makes sense.

[–] yggstyle@lemmy.world 1 points 7 months ago

I think you're correct. I think this was likely min/maxing on the designers part. Assuming there were open / and 'green' spaces inside or within, say, a cluster of these I'm sure it would be generally acceptable for most people. My fear with designs such as these is vertical creep. What is nice and functional at 2-3 stories becomes a dystopian concrete labyrinth quite rapidly.

[–] yggstyle@lemmy.world 1 points 7 months ago

Shade is good - been in the south for 8ish years for work - It gets toasty down here.

A combination of artificial shade and greenery can have multiple benifits. (where applicable obviously - not all regions can support it nor should they try)

Shade can be functional too. There's been some interesting research into panels/pigments that radiate infared light at the wavelength that can escape our atmosphere producing a cooler than ambient surface that could have a variety of uses. A ton of recent advances in solar technology as well.

[–] bitwolf@lemmy.one 9 points 7 months ago* (last edited 7 months ago) (3 children)

I watched a YouTube video on it and they mentioned they designed the structure to maximize shade.
This combined with the white buildings knocked more than 20° off of the ambient temps within the neighborhood.

Edit:

The video.

Kirsten Dirksen tours a lot of homes / areas that focus on sustainability or break the mold.

[–] Evil_Shrubbery@lemm.ee 3 points 7 months ago* (last edited 7 months ago) (2 children)

Yeah, I don't understand, were trees or solar panels not available? Not to mention that maximizing shade could be achieved with a simple pattern and taller buildings or rooftop gardens/panels. Even a simple mesh tarp (mimicking leaves) over the allies does the same trick without claustrophobia :). At such latitude shading from the top is way more effective than from the sides.

And what walkable city/neighborhood doesn't have a piazza for people to gather & eat, drink, shop, etc?

Dense structure placement like that def looks like developers maximizing buildings per land, not for the community.

[–] bitwolf@lemmy.one 3 points 7 months ago* (last edited 7 months ago)

I do agree with you this would be a very sensible and effective solution. I also was disappointed that seemingly no thought was put into integration of solar / shade plants.

However I do want to stress the importance of having access to a broad view of the horizon and sky.

That said they totally could have made little pockets with this lattice and 10x'd the environment on the passageways and generate power/food.

[–] Flumpkin@slrpnk.net 2 points 7 months ago (1 children)

Have you watched the video and has it changed your mind? I'm curious if it's just the article only giving that shitty overview photo. I only watched the video and thought it was quite nice for high density urbanism. An alternative to suburbia modeled after classic European cities.

Besides shade, narrow streets might also reduce amount of walking distance. So if you make it bigger you end up with less functionality.

I'm sure if they replicate the concept it could look quite different in other climates.

[–] Evil_Shrubbery@lemm.ee 2 points 7 months ago (5 children)

Yeah, seeing the main streets (like on the map) is what redeemed it a lot, however I do not understand buildings that narrow together, like from the personal space POV. A meter/few feet wider allies (or distances between front doors) would make a lot of difference.

Also I do live in a classic European (fairly) walkable city. Not that I'm comparing directly, it's a different situation. But over here narrow allies or window views of only your neighbour are usually found in old villages, where money was tight & a lot of expansion was done over existing buildings. Or where other barriers exist (historic city walls, narrow peninsula, rivers, etc).

I'm not even saying I wouldn't live in Tempa, it just seems like a really cheaply executed concept (albeit "classical", yet new, but you are not getting old buildings).

@Evil_Shrubbery this, why is it so full of dark and creepy spaces?

[–] Evil_Shrubbery@lemm.ee 1 points 7 months ago (2 children)

I wrote that comment before reading the article - it's supposed to be fancy/expensive. Wtf. Prisons have better views then those (and bigger windows).

I hope they are not innovating slums for middle class, lul. Tho they can be good, fun, & cozy (just not rich), James May portrayed one nicely in his India season of Man Abroad

[–] livus@kbin.social 2 points 7 months ago* (last edited 7 months ago) (1 children)

If you image search Culdesac Tempe Arizona there's some ground-level imagery. Most of it is artists' impressions of what looks like people wandering aimlessly in the outdoor spaces of a mall.

[–] Evil_Shrubbery@lemm.ee 1 points 7 months ago* (last edited 7 months ago) (1 children)

Ohh, this looks normal for humans. It makes more sense now. Still a horrible top pic in the preview.

Oh, I see, how it makes more sense. Lul, looks like one of them 'shopping villages' (basically malls but in village form), and I like those.

[–] livus@kbin.social 2 points 7 months ago* (last edited 7 months ago)

@Evil_Shrubbery I think what I linked was the architect's concept image; the top pic is what has actually bern built so far.

[–] Misconduct@lemmy.world 2 points 7 months ago

It's in Tempe. It gets to be like 120 there in the summer use your brains you goobers lol. They're maximizing shade because without doing that nothing is walkable in that heat

[–] Evil_Shrubbery@lemm.ee 1 points 7 months ago

... or maybe it's a pic after a devastating (muddy) flood that squeezed all the houses randomly together.

[–] yggstyle@lemmy.world 2 points 7 months ago (1 children)

Oh that's gonna be premium in a year or two. Welcome to your 'block.'. You get sunshine indirectly between the hours of 11 and 1. Curfew is at 10. Be back in your cube by then.

We have the capacity to build green open neighborhoods using existing block structures and infrastructure... we just chose not to because it's prime real estate. Roads and repairs are expensive... but if we replace it with more homes it's better revenue generation.

I'd love to see a proper balance struck but for an idea to take root the seed must be blessed by capitalism. For it to grow it must, above all, be profitable. For adoption it must be accepted by the elite.

I cannot go into details but - I've seen some outstanding ideas of how to convert a city block by block and they do give me hope... but listening to discussions and debates on it is soul rending.

I'd genuinely love to see it in my lifetime- And in a form that strikes a balance that is both sustainable and actually an improvement in living conditions.

[–] Misconduct@lemmy.world 6 points 7 months ago (1 children)

Lol it's Tempe. The goal is to avoid the sun I promise you

[–] yggstyle@lemmy.world 1 points 7 months ago (1 children)

Yeah direct sun can be a problem too - it's getting toasty out. That said there are unquestionably better ways to do that without making anti car into a maze of alleyways.

[–] Evil_Shrubbery@lemm.ee 3 points 7 months ago (1 children)

Exactly.

Found this pic, the og idea seems to be (like everywhere in the world) to have blocks with community areas in the middle. Not sure where the top pic fits in tho.

[–] yggstyle@lemmy.world 2 points 7 months ago (1 children)

Yeah that is far more logical - The pics in your other post illustrate the concept well. The major hurdles are transportation and retrofitting. New towns and construction are well and good but for adoption to take off benefits must outweigh existing convenience and not eliminate mobility overall. Scalability is another one.

It's a lot to try to balance. Designs I've seen get the most traction involve reclaiming blocks and offering elevated rail to move about or use of subway where logical. The more modular the better. And I've seen a few like that get /close/ but they'd strike out on scope or would piss in some lobby's cereal and get early enemies. That one's a minefield.

I feel like we could see some rapid creep if someone got the ball rolling and it was reasonably successful... but that's a hell of a big step to take. And make no mistake - it will be a retrofit that starts the creep. Has to be a city or a substantial dense town to draw interest.

[–] Evil_Shrubbery@lemm.ee 2 points 7 months ago* (last edited 7 months ago)

Another major hurdle is the petrol industry & incentives for the few to get rich my building & maintaining roads. Public transport on the other hand (hopefully) doesn't generate profit as it is a service for the people. So those in local/regional/state power have more to benefit (personally , financially) from building roads. It's like taxes, people that influence/write/adopt tax policies are the ones that benefit from tax cuts whereas the majority loses more through all the services they have to pay double for.

It takes civil organizing to produce politicians and high enough demand for such change. Often through things like higher commercial rents or local service fees (like stores in the center pay more for water or waste disposal as they would in a mall outside the city - and the difference pay the customers though cars, time, and well-being).

[–] aeharding@lemmy.world 5 points 7 months ago (3 children)

Ok but Phoenix is shit. Just a terrible “city” even for US standards. Why would anyone wanting to live car free live in Phoenix?

[–] doctorcrimson@lemmy.today 5 points 7 months ago* (last edited 7 months ago)

I spent two weeks in a cheap OrangeTree Resort booking and got groceries, took a tour of ASU, and went to a bunch of restaurants using only a week-long bus pass which also covers metro. It was way nicer than living in buttfuck nowhere Dakota where I have to drive 30 minutes to pick up groceries. I plan to move to the area at some point.

Scottsdale was annoyingly a big block of houses, downtown Pheonix near the airport had tons of litter and the occasional homeless person, never went further towards Mesa, but overall everything was an improvement from where I had come from.
