The collapse of the dynamically stable climate on which agricultural civilisation is founded is vanishingly unlikely to be prevented at this stage - no-one has

The collapse of the dynamically stable climate on which agricultural civilisation is founded is vanishingly unlikely to be prevented at this stage - no-one has ever even outlined, let alone detailed, even one remotely plausible political route from business-as-usual to where we need to be. As others here note, it's fundamentally a problem of world politics, howevermuch a proportion of HN readership may wish to suck at the corner of their technological comfort blanket. As we have no meaningful world polity, it's unsolvable. Our civilisation will almost certainly descend into chaos & war as the early effects of climate collapse roll in this century. Look at the convulsions flowing from a tiny trickle of refugees into Europe in 2015-16. That was barely a taste of what's to come. It's hardly surprising - nothing in H. Sapiens' constellation of seemingly unique traits (cognitive flexibility, sociality, cultural transmission through language etc) equips it to make collective decisions on a global scale. It's kind of telling that just as it's becoming most blindingly obvious that all our major challenges are planetary, there is a general retreat from commitment to global decision-making. We're not adequate to to the task. This isn't anyone's fault - it's just biology.
