…along came David Roberts, and made a mind-blowingly good observation:
Will unexpected, rapid changes in coming decades be good or bad, positive or negative? That depends on millions of individual choices made in the interim. Some of those choices, if they happen at just the right moment, could be just the perturbations that spark cascading changes in social, economic, or technological systems. Some of those choices, in other words, will be incredibly significant.
Which ones? That we cannot know. It could be any of them, any time. Precisely because we cannot know — because any one of our choices might be the proverbial butterfly’s wings — we must act. We must take advantage of every affordance, grasp every opportunity. We don’t know when history might unlock the door, so we have no choice but to keep pushing on it.
Also an important point:
Remember, there is no “too late” here, no “game over” — it will be a tragedy to shoot past 2 degrees to 3, but 4 is worse than 3, and 5 is worse than 4. Being unprepared for any of those will be much worse than being prepared. The future always forks; there are always better and worse paths ahead. There’s always a difference to be made.
Go read the whole thing, in which he draws inspiration from chaos theory and history. His perspective is new and original–and seriously, stunningly hope-inducing.
