"Now" still seems like a very good answer. I doubt that if we stopped emissions today, we'd see any positive changes for decades, and that's if we're very very lucky.
- mirimir 10y agoYeah, "now" seems a good answer. A couple decades ago, I would have said "no clue, really". But now, it seems pretty clear. And yes, even without positive feedback, it would take several decades for forcing to relax after carbon emissions ceased. Which is very unlikely. So I really do think that it's time to consider active mitigation. But I'm not even very optimistic about that, given the likely positive feedbacks. Requisite mitigation requirements would also be going exponential. And where will the energy for that come from?
