(The few remnants from those times which survive do so in environments where oxygen can't reach, like in the depths of the oceans.) The cold would have killed off a lot of life forms eventually. But the oxygen poisoned them a whole lot faster! Easy to overlook, since you now live in an ecology which requires what was once the worst toxin going. Not to argue that global warming isn't a valid issue. But toxic waste can be more urgent.
