OMG...* Not...* global...* COOLING!* snic, snic* I think the temperature goes up and down quite a large amount (10+ C) due to a variety of natural causes, and yet stays in a bounded range without diverging to a desert world or an ice world. Somehow mammals have survived 200 million years and many cycles of this. Even great apes have survived 40 million years of it, without any technology. I guess one school is that we're just plain lucky that things haven't exceeded that range, and a small extra push could send us over, to a 2nd Mars or Venus. Frankly, I don't believe it. I think there must be some natural negative feedback "thermostat" that we don't understand yet.
