Good points. I think even if we could muster collective action it would be required on a global scale. Related to this is that in many cases large emitters of green-house gases are largely divorced from the consequences. Ultimately most people around the world will feel some impact but it's not really a problem in the here and now. For example animal husbandry (cattle and possibly sheep) is apparently responsible for emissions of methane which is in theory has a disproportionately larger impact on raising global temperatures...but we'll have a hard time convincing people to stop eating those meats. Especially in parts of the world that are becoming more affluent, have large growing populations and are rather keen on enjoying their share of steak or leg of lamb
