Bluntly: far fewer people, sustainability built into every process, no more oil, very high cost for transportation unless it is by ship, personal transport will be very costly and you won't do it unless you really have to. Think '1850' but with transistors.

>far fewer people Also bluntly: how would we do that ethically without severely restricting reproductive rights or "cleansing" populations?

We wouldn’t.

While some meat eating being required for nice food is subjective, I'm struggling to see what the suggested alternative to cars for all weather personal mobility is. I want to go to visit my friend Bob who lives 10 miles away but the rain is pouring down. What do I do in a carless world? Btw: CO2 emission taxes, road taxes and congestion charges are a great idea.

> I want to go to visit my friend Bob who lives 10 miles away but the rain is pouring down. What do I do in a carless world? - you wait until it stops raining - you bring an umbrella - you bring a change of clothing - you bike or walk - you ask Bob to meet you halfway Kids here in NL do this every day, sometimes across even longer distances (when they're high school age and live in rural parts of the country).

- you visit him after the rain is over

(That comment must be satire)

> while putting a substantial portion of GDP into building nuclear reactors and removing carbon from the atmosphere. The first thing takes years and we still don’t have feasible technology for the second. Not to mention that we would still have a lot of emissions from transport, manufacture, and meat consumption. A technological silver bullet would be cool but the reality is that we don’t have one and there’s nothing…

The problem with the term "silver bullet" when used in these discussions is that it's used to dismiss any proposal for a technological solution. I can flip that around and say "a societal silver bullet would be cool but the reality is that we aren't going to convince people to reduce their consumption." Which I actually sort of believe. I think a technological solution has a much better chance of succeeding than a so…

If someone came to you with a problem on a project, and you had a hard deadline of the end of the week, and you had two ways to go about it - 1) this is gonna be a pain in the ass to implement, you'll all be pulling 12 hour days but it's straightforward and crystal clear in how this directly addresses the problem, and 2) some completely unproven solution, that even when fully implemented the math/logic doesn't really work out in terms of it solving the problem, but there's some small hope that it might for some reason, and you'll get to wrap up the week on a Thursday no sweat (the honest reason), which do you spend the rest of your week pursuing?

Now imagine it's not just some meaningless project at your job but a matter of life and death for the majority of life on Earth, which do you pursue?

This is what OP means by changing the way we live. Sorry but getting rained on a bit is least of our troubles. Imagine there are places like Netherlands where it rains all the time and people (including very old ones) bike around the city…

the mode share of cycling has gone down in the netherlands over the last 30 years. 12% of average income households are car-free; it's 25% overall and 6% for the wealthy. this is despite the mode share of cycling in amsterdam increasing 50% in the same period. even with a cycling network fully connecting the southern half of the country, decent connectivity in the north, road design in the major cities that is intentionally hostile to intra-city car commutes, and an ostensibly pro-cycling commuter culture, people don't want to bike more than a couple miles if they can afford not to.

if you want to shape the behaviors of the world's people as you suggest, you'll need fascism. hard sell when there are already two paths to clean energy abundance, two paths to sustainable driving, and many paths to damage control competing in the public discourse.

On the flip side, some people reject technological solutions on principle because for them, it's not about solving problems, it's about atoning for the sins of humanity.

We have enough resources to provide heating and running water for every living person on Earth, it is just not allocated fairly and smartly (e.g. in my country we flush the toilet with very good grade water meant for drinking, because historically we don’t have separate piping for less potable water and we are rich in waters). But do we really need to be able to order some bullshit plastic shit from China for 2 dolla…

But none of the examples you give move the needle enough with regards to climate change.

You're just following what feels like it would be good for the environment (and maybe it is good for your local environment) but isn't actually impactful at a large scale.

You write eloquently, but futilely.

That all sounds okay at an individual level, but to affect the massive change we need, relying on moral self-agency is not going to suffice.

So do you want governments to legislate that you must live with your parents? Or that you must not eat meat? Otherwise it's fine and good that a small share of the populace will make these choices on their own, but we need an order of magnitude more.

The enthusiasm with geoengineering among the HN community is worrisome. Not sure which computing analogy would drive home the complete recklessness of this mentality but the Earth is not something you can reboot to the last working state once you harebrained patch implodes. It is true that we have been slowly geoengineering for ages (initially unwittingly, recently with eyes wide open) and it is also true that our mo…

> The enthusiasm with geoengineering among the HN community is worrisome.

It reflects the gravity of the situation. What I find incomprehensible is a reluctance to consider investigating such steps when the extremes of climate model forecasts are so horrific.

interesting thread, so the multitudinal effects of gas output came back with more nuance than anyone expected.

the oversimplified explanations of "this gas bad" are finally worth collapsing because nothing only ever does just one thing.

on the bright side, if this cloud seeding business helps keep everything cooled, i suppose that's a good takeaway.

Am I understanding that page correctly? Sounds like 3–4 deg C of cooling for an estimated $5 bn/yr.

Yeah, if climate change really was an “emergency”, mitigation would be extremely cheap. With big side effects. Nevertheless if it really were an emergency … in real emergencies, triage happens, and downsides are taken for granted. Thankful that there’s no real emergency yet, but I suspect governments will drag their feet long enough that there will eventually be one, and then emergency relief will be deployed anyway,…

Governments will drag their feet, but there are hundreds of individuals who could float a few $B a year to get this started.

Once it's working, I expect they won't be allowed to shut it down.

> Its like your laptop is on fire, so you throw some water on it. Is it a lithium fire? I think this might be a very good analogy.

Yes, exactly.

But it might just be a simpler fire.

But if smothering isn't an option, you take the lowest risk choice, which is the water.
