When you say 'fix' do you mean 'prevent a two-degree shift' or 'transition to an zero-net-emissions economy'? Or do you mean we can avoid some survivable threshold higher than two degrees?

I agree that useful action is possible and important, but I'm starting to feel that our last chance to avoid catastrophic climate change was sometime last decade or the one before.

I mean both, first 'prevent a two-degree shift' then 'transition to an zero-net-emissions economy' and finally even negative emissions. This was almost solved in the 1980s and wasn't but that's a sunk-cost fallacy. The chips are down and we are where we are, so let's roll forward and get this solved.
