If we want to have a stable livable climate we need to.live with the emissions of the average Cuban (Professor Kevin Anderson) That allows the worlds poorest to have more emissions per capita and the worlds richest to come down a lot, and by a lot I mean a metric shit load.
How we do that and what that looks like is up to us but if we don't soon, we'll likely collapse. civilisation anyway and none if it will matter and we won't be talking about it on here.
