Which phase of abrupt climate change do you feel would have more severe repercussions for mankind and life on earth, a mini ice, a full blown ice age, or a hothouse planet by the likes earth hasn’t experienced since the dinosaurs ruled the planet?
Probably a full fledged ice age would be the worst, because so much arable land in North America and Eurasia would be lost due to the extreme cold. The world would also get much drier, which wouldn't help. But massive global warming would be horrible as well, with sea levels rising 200 feet and possibly unbearable heat and humidity in the tropics.
Why did you have a mini ice age as a poll option? It definitely seems to me that a full fledged ice age would be worse.
