- 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.
