> It would take far too much effort, and also far too much cooperation between different nations that all intensely hate each other. I share your pessimistic assessment and I would frame it differently. The thing that strikes me, above all, is that this is the first project that really requires cooperation on this scale. Basically everything before was possible with smaller groups following their own incentives (basically bog standard capitalism). The cost of cooperation was not worth the returns. This is different - we need to learn to cooperate on a previously unheard of scale - and (as you note) we need to learn to cooperate in a way where we don't totally trust others. I just saw Oppenheimer so, to draw a historic analogy, it's like you have to run the Manhatten project...but also actively share work with Russian and Nazi scientists to finish the project earlier than US science could alone. It's on an entirely different level of difficulty that we have never really needed to attempt previously. For instance - are oil & gas companies being disruptive and acting in bad faith? Yes. Do we need them to stop? Absolutely. Probably the easiest way is to reward their bad faith action if they will really start cooperating. At this stage we need them to be winners. Justice is a luxury for people who are in less dire conditions. > Even if, for instance, Germany manages to become 100% carbon-neutral, that isn't going to help much I think you're totally wrong on this and I encourage you to look into the science on it. We can make the planet as hot as we want. Every bit of warming emission hurts. I'd also argue that, in the same way that California standards change things across the US (because they are so big) the developed world truly abandoning carbon would dramatically impact the rest of the world.
