On top of that, how can you look at the world history (which you are hasty to dismiss) and still believe that whatever new world order of yours would be immune to the same power struggles, in and out fightings, and ultimately the same destructive behaviours which are contrarian to our own common benefit as a species? What would prevent the same griefs you currently hold against “Europe/North America” to be resurrected there or elsewhere, as they were countless times and universally throughout history?

Now you’re moving the goalpost from fighting this specific climate crisis to preventing all ecological crises forever. I don’t care enough to argue that point, even if I have strong opinions about it, because it’s so beside the point that it would be a waste of my time. It seems almost intentional ngl.

The only way that you could hope to gain traction in your stated mission to abolish capitalism is by convincing others that whatever comes next will stand the test of time, and so I am legitimately curious. I don't think we can afford buying into pretty but empty promises.

Of course it is. I have a wonderful thing to teach you today: the material world doesn’t care about your (or mine) opinion, or this planet would have alternated between being flat, spherical, carried over the back of a giant turtle, concave, and all of those simultaneously. Similarly, we could unanimously decide that the branch we collectively sit on should be trimmed, and that wouldn’t make it a good decision either. Opinions alone are no reasonable basis to decide what to do next, the best thing we have is science, and the second best is history.

Okay yeah you have no idea how organising society works. Good luck doing anything in your life while ignoring your own opinions, or worse, equating them to scientific facts. What is your opinion on the IPCC, I wonder.

I really don't understand what's causing your vivid reaction here and you said nothing to help me understand it. But okay.

I trust science and the (very much apolitical) scientific method, which the IPCC embodies

Oh yeah, there is nothing political about allocating which kinds of research gets done or doesn’t. Science is just a soup that we throw money at and stir around and funny theorems and statistics boil out.

So I take away that you are a science denialist. If so, I don't see the point of continuing further, because this could be all fake news as well. And if not, then I'll ask what you gain from removing the scientific step from the decision process. And I would re-iterate my offer to provide evidence that the IPCC is biased as you claim.

You seem to have it all sorted out to explain me how that solely rests on the shoulders of “the villain capitalist West”, and not on the many other easy culprits, like, I don’t know “people are afraid of change/the unknown”, “significant changes always take a long time to be enacted”, “people like to postpone or avoid at all cost tough changes, especially those that are detrimental to their quality of life”, “why would I let other people decide for myself how to live my life, especially when I’m old and won’t have to deal with any of this”, “why should I have it worse than that other person”, “why am I hostage of the bad behaviours of other humans long dead”, “it takes a lot of mutual trust and reciprocal guarantees for committing to sacrifices with the assurance that the other side of the fence/border/geopolitical spectrum will not use it for its own short-term benefit”, and this goes on and on.

Oh look, a lot of political and social questions. All of those are valid of consideration, but the overarching system in which those are embedded isn’t because it’s “opinionated.”

You missed the forest for the tree, didn't you? At the very least you deflected my question. In the present world order, how do those pertain to capitalism, and in the new world order that you propose, how are they addressed?

Please feel free to quantify scientifically how much influence dead people’s laws should have in society. The IPCC must have a couple of papers on it.

I know this is sarcasm and I have no idea where you are going with your dead people's law, but at least in the case of the social questions above, science, and the IPCC in particular could provide some partial answers (e.g. how long/how big the sacrifice, how to adjust to many aspects of every-day's life), which will absolutely help weather the incoming storm. I really don't see the need to denigrate.

your bourgeois overlords don’t really care much about your opinion of what should be done to society. So long as you keep consuming as they want, they’ll barely even think of you, and capitalist society will keep trudging on towards the 4ºC mark.

Who exactly are my bourgeois overlords? And how are they compelling me to over-consume exactly? Perhaps it's not obvious but you and I must be very close on the political spectrum, and I could be your best ally when it comes to proposing a more sustainable lifestyle for the future. My problem is that your discourse is not nearly as polished as you make it to be, and shooting the messenger without addressing the core of the issue will not give you legitimacy and support. I live in a mostly socialist highly-educated country where our political landscape is diverse and organized in coalitions who must compromise. Unlike some stereotypes, we were not "brainwashed" during the cold war into believing that the world must exist in an extreme form of either communism or capitalism. Capitalism isn't something that I see practically affect my life because without specifics (which this thread is lacking en masse), this is just an abstract construct. Market laws (offer vs supply) do, but this is trade, this doesn't equate capitalism, and I think I already made that point clear.

I’ve provided some evidence of communism being a better alternative

I don't think you did. All I (mis)read is that abolishing capitalism to be a condition for addressing climate change, and I've been begging to know more about how it will play out in practice.

Riddle me this: What is, in your factual scientific opinion, that which is preventing humanity to actually combat global warming and climate change as they overwhelmingly want to? The answer will say a lot.

I can only offer my biased and limited opinion, sorry. Part of which you already got in my paragraph about the "easy culprits" (people being scared of change, etc) which still stands. I believe there are many large issues, the fact that most people are in denial about it is a significant one: no matter what we do now, we will collectively take a huge cut in our quality and comfort of life for the centuries to come; pensions, property titles, diplomas, insurances, … will become meaningless and that's a tough one to swallow. Most people are just incapable to imagine such a world, and won't react until too late. Then comes the fact that most countries have experienced the late stage of their demographic shift: you get a large population of elderly and politicians representing them who won't get to live through the hardship of climate change, and who have little to no incentive to do anything about it. Then comes the fact that this is a global phenomenon that affects all countries unequally but requires all of them to agree, commit, and execute toward a common goal. We have no global instance with the legitimacy to oversee and arbitrate in this context, and I doubt there will ever be one. This post is long-enough but I think you got the gist.
