Its a case of prisoner's dilemma. Individuals making the proposed lifestyle changes in order to make a genuine dent in AGW amount to jumping on the tracks in order to stop a freight train.

This is the one issue where I feel some sympathy with the right. I hate "Virtue signaling" about as much as they do. I'm sorry, but if you are going to snap at people over eating beef, while you fly/drive all over the country/world unnecessarily, you are absolute full of shyte.

Don't forget buying mountains worth of crap that gets used for a month or less and trashed.

Spot on! It's probably the stuff you buy that has the biggest impact on the planet.

Right to Repair and some type of incentives that actually rewarded it would probably do more globally than most other consumer level solutions.

I am not a vegan. My social world in D.C./NYC has many secular, left-wing, vegans. Many of them are friends or loved ones. They demonstrably speak their mind in front of me on countless issues on which we disagree.

I have dined with them countless times at restaurants where they order vegan and I don't. I have never once been "snapped at" about my dietary decisions. Some of these people have dedicated years of their life to non-human animal rights activism.

So I am very skeptical that this shaming occurs at any appreciable scale. I suspect it is mostly psychological projection: one doubts the morality of one's decisions, judges oneself harshly, but experiences this as the judgement of others.

Thank you for articulating this so succinctly.

Prisoner's dilemma is a bad reference here.

Prisoner's dilemma is about situation when optimal outcome requires cooperation from all participants.

In the situation with climate change, personal decisions of 99% of Earth population do not really matter.

[Mordisquitos]

You are correct that this is not a prisoner's dilemma, it is a tragedy of the commons[0]. However, if a wizard could magically control the "personal decisions of 99% of Earth population" and make them optimal for reducing CO2 emissions then, believe me, climate change could be trivially solved.

It is a classic cooperation problem. Perhaps not prisoners dilemma. Perhaps not at individual scale. Probably tragedy of the commons.

Cooperation is not consuming fossil fuels. Defection is consuming fossil fuels.

If you cooperate and other defects you suffer climate impact and expensive energy (expensive everything, worse economic growth than others).

If you defect and other cooperates you suffer climate impact but at least you get cheap energy (cheap everything, more economic growth than others).

People, nations, corporations, etc don’t stop using fossil fuels because they incur a penalty against their competitors if they volunteer to and their competitors don’t.

WDYM personal decisions don't matter? Industrial and agricultural sectors, which both in sum contribute 50% of total greenhouse gas emissions, produce what is in demand from consumers. Another 15% of emissions is from personal vehicles. Changing personal habits is the only way we can ever reach some utopian climate targets. Utopian because old habits die hard.
