If true, it's unlikely to persist for long. We know from paleoclimate data that both Greenland and Antarctica will significantly melt out w/ CO2 as high as it already is, much less any realistic peak level we could achieve.
- hugh4 11y agoOr if CO2 had never risen at all, right? End of ice age and all that?
- themgt 11y agoYeah, there's actually a reasonable case that our initial historical fossil fuel burning (say, up to 1950, 1980?) saved us from a new ice age that was about to dawn. We unfortunately since then have pushed the dial way, way further, likely now past a tipping point towards a mostly ice-free hothouse planet.
