We have maybe one year before we know effectively that we failed
politically speaking.
We're either going to have to wipe out the fossil industry in ten years and replace it with alternatives, or we are going to watch civilisation unravel. Anything less than a Green New Deal from 2020 that eliminates emissions 90-100% in the next ten years and it's game over. there is basically no way we can do it in less time and still have a "functioning" economy. We need sanders for that, but he is the last and only shot we've got. I'm not brimming with confidence to say the least.
Even if I conceded the benefits of capitalism over the past three hundred years, and the evidence IS overwhelming, Capitalism can't handle that kind of transformation. It's not designed to. Competition resists central control and planning and Saving the world is "too expensive" and hurts profit margins. Capitalism has screwed up our priorities that much.
It's far from certain that a planned economy would do it better as the history of communist countries environmental record is very poor given they focused on heavy industry. but you definitely need the central co-ordination to transform the economy in such a short space of time.
I just despair at this point. We've wasted decades when we could have got this sorted by now.
