Do you imagine that you've done enough, and it's only those meat-eaters and plane-flyers who are causing problems?

Just living somewhere with heat and electricity and water, posting on here is adding to CO2 emissions, unless you're doing it from a 100% renewables-powered off-the-grid location. Even if you are, the messages you send onto the internet are routed by entities that consume fossil fuels.

Every building you enter, all the food you eat, every product you benefit from has been made with fossil fuels.

If you seek any goods or services in today's world, if you use any aspect of industrial civilization, you're contributing to the warming of the planet.

Of course, just by being alive everyone contributes to greenhouse gas emissions. But there’s a huge difference between somebody who flies 5 times a year and eats 10kg of beef a month, vs. someone who doesn’t do this (ceteris paribus). There’s a huge variance between individual contributions that matter in the sum.

And sure, a big part of emissions come from industry. But in the end, industries create products to be ultimately consumed by people. So, by changing our behavior we can also change industry. This doesn’t mean that we shouldn’t also hold producers accountable and pressure our governments to set the right incentives. But just saying we as consumers don’t have any power to change anything is wrong.

I agree it would be good if people flew less and ate less meat, but have you checked whether those actions would be sufficient to meaningfully slow climate change, making it unnecessary to consider geoengineering?

I don't like the idea of pumping stuff in the atmosphere either. I would rather make a space sunshade, although I can't say I understand the economics well enough to compare it with sulfur aerosol. Either way, we're not on track to control the climate right now, even if consumers do some nice things. We need more time.

It's not just on the consumer, though. Policy makers need to get a grip. Yes, reducing meat, not flying, less heating, buying less crappy stuff, consume local food, etc. but we also need to allow people to move around in trains, put taxes on food imports, forbidding 2t SUVs, control birthrate, etc. We live in an extremely suboptimal society given our current constraints. All that can be enough for our population to live sustainably but that requires planning, not more time to procrastinate...

Most people, both in developed countries and across the world, rank climate at the bottom of their list of concerns. Some enlightened elites care about it, but they can only do so much.

That situation will remain exactly the same if we buy more time with geoengineering. But at least with geoengineering, hundreds of millions of people might not be driven from their homes by literally unlivable heat conditions in this century.

If those people want to live in your backyard, does geoengineering sound a little more appealing now?

> Most people, both in developed countries and across the world, rank climate at the bottom of their list of concerns.

My impression from the recent polls I've read about was that this is generally not true anymore, specially over here in western Europe after the summer we had.

> That situation will remain exactly the same if we buy more time with geoengineering. But at least with geoengineering, hundreds of millions of people might not be driven from their homes by literally unlivable heat conditions in this century.

This is just witchcraft. There's no way back from it and it's be a petty excuse to keep doing business as usual and generate profit. And keeping a stable climate isn't the only ecological challenge we're facing.

> If those people want to live in your backyard, does geoengineering sound a little more appealing now?

Absolutely not. And "those people" are already crossing the mediterranean ocean by thousands to live in my backyard.

[civilized]

I don't know who is making petty excuses or doing witchcraft. I make no profit from fossil fuels and I would rather see decarbonization at a much faster rate than we are doing today. The problem is, we are going to heat the Earth quite a bit at this point no matter what. Something has to be done about that as well as about the emissions that are making it worse.

This is not only about morality and profits. It is also about our actual Earth and what happens to it. It's still going to heat by several degrees even if humanity has the enlightenment that many people here seem to dream will happen soon.

Even if you are doing it from a renewable-powered off the grid location. Think of all the CO2 emitted to create those components and the logistics to get to that off grid location.

That's not always true.

My neighbours are true eco warriors. They have planted literally hundreds of acres of trees and they live a carbon negative life. Granted, they are unusual, but it is not true that everyone is contributing. Just 99% of us.

[civilized]

Unless they're caring for those hundreds of acres of trees, a lot of them are probably dead.

Carbon accounting and the real world aren't quite the same, and the bias is always toward underestimating someone's CO2 footprint and overestimating the impact of mitigations.

[beachy]

What? I can see their property from mine and it's a rich forest thanks largely to their work. I don't understand where you are coming from.

[civilized]

That's great, but most people don't have hundreds of acres of empty land to plant trees on.
