    far from fucking capiche. Tho, it's not you're opinion I care about.
    Humans created the spike in CO2 levels during the last 100 yrs, levels higher than has been seen in the last 1 million+ years. This isn't gradual as you suggest, this is a huge spike in CO2.
    Mammals did exist back then, but had millions of years to evolve to what they are today. You cant ask a species to evolve to cope with an environment that changes so radically in 100 years time.
