At this point, we should be throwing our money at geoengineering and technology in order to try and deus ex machina our way out of the pending climate crisis. We've wasted so much time that now there really is almost no other option. No one is going to lead on this issue, so it's our only hope left.

That said, I am optimistic that once the economic incentives align scientists/engineers will be able to save us from the worst effects of climate change, and down the road even reverse the effects.
