We are actually more in danger from global cooling. "Normal" in the last 400,000+ years is that we are in a long Ice Age, with periodic short intervals of warming. We are currently in one of those short intervals, and could be overdue for another dip into Ice Age.

It would be ironic if "global warming" did exist, and it was the only thing holding off the Ice Age...

I’m not even sure AGW would be able to swamp this out. We’d have to be able to explain ALL of this in terms of atmospheric CO2 content DRIVING the rest of it, before being able to count on that.
