Honestly I’m kinda tired of this because you seem to be deliberately missing the point.

I mean, I hear you, but from my perspective, you are the one missing the point: I replied to you in a more general case…

There definitely were people all over the world waging massive wars to protect/expand their land and agricultural capacity instead.

…but you keep bringing back the discussion to modern specifics without explaining why they somehow contradict the broader thesis:

A thousand years in the past there weren’t people in Europe/North America waging massive wars to protect their sources of oil across the world.

Your argumentation is presentist and mine is anthropogenic/historic.

I don’t particularly care about any pre-factory man-made ecological catastrophe because what I (and others here) argue is that this specific one is being perpetuated by the undemocratic owning of the means of production.

Indeed, but my point is that you very much should. Let's suppose that we have it your way, and overnight we suppress everything undemocratic and capitalistic about this world. Would that solve climate change? Your conviction is "Yes, because such and such things that (you believe) caused it (but no evidence was given) are no longer there". This is not only extremely naive (and unproven), this is also illogical: in essence you would have replaced something we know by something else we don't (and that moreover could be worse), and be expecting a better outcome, out of pure faith, with no evidence. 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?

This is the crux of the issue here: you propose change for what looks the sake of change, whereas I'm more interested in understanding why we are where we are now, despite all our knowledge, but still unable to move. That is, so we finally get a chance to break the circle and not just burn the world down in yet another desperate revolution.

The IPCC doesn’t make manifestos nor do they advocate for political action

Which is why they matter, they come before in the decision process, so that any serious manifesto or political action gets some amount of legitimacy and bearing in the physical world that we collectively live in.

, despite suffering from intense lobbying from both corporations and political parties. They work specifically under the framework of liberal capitalism and the directives of the USA government and bourgeois interest, even if the individual researchers are often honest and diligent.

I trust science and the (very much apolitical) scientific method, which the IPCC embodies, by being the largest venue for the best scientists of this world to convene on the subject, and I have no reason to believe that their methods have been corrupted. If you have any evidence of that, please offer it for the sake of our common good. If you don't, please go away with your FUD, or, better, put together a more qualified and adequate team.

Another easy argument to be said is that this same panel (corroborated by independent studies) came to the conclusion that stopping climate change would be more beneficial for the world economies (and the current world order that you despise as a result) than not doing anything. Which kind of makes sense in light of the ever worse food and water wars, wildfires and destructive weather. Nobody wins.

I could laugh but I guess some people out there really think that “political orientations” are unproductive for deciding what to do politically.

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.

The most efficient way to enact change (IMO) is to commit to actionable goals in light of desired outcomes (e.g. how many plants of which type we need to open and close, how many cars and trucks on the roads, …).

Do go on, what “actionable goals” have been committed to and are being enforced right now in capitalist countries? Which ones are even likely to stay in force after an election cycle? How have capitalist countries fought against climate change when it went against the profit of their ruling class? The gist of it all is that all of those “actionable goals” need to be enforced politically, which has shown to be impossible (or at least very unsuccessful) under liberal capitalism over the past 30 years we’ve been aware of this crisis.

Good points, really. Then the argument should be turned into "why were those actionable goals not implemented".
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. Like I said in another post, sects and religions. We are not geared-up as a species for reacting rationally in this scenario. We have never been confronted to such a threat, and required to exhibit such an amount of coordinated sacrifice. All we need is to prove that we are better at survival than lemmings. And sorry again for finding ludicrous the idea that taking out capitalism would do anything of substance.
