"These observations should dispel in one fell swoop any notion that recent global warming could be natural."
Really? Because climate has never, ever, not even once, shifted quickly?

Note the huge uptick in average temperature starting roughly 11.5k years BP. I'm pretty sure the foot-powered cars the Flintstones drove didn't warm the earth, so this must've been a natural event. Saying that it's impossible for current temperature trends to be unnatural flies in the face of something that has already happened once, almost within recorded history; not to mention all the times when it happened outside of recorded history.
This is why some people, like myself, do not take climate alarmists seriously. They make these grandiose pronouncements that have little, if anything, to do with the facts.
That's not a very reassuring comparison if you want to calm down the alarmists. You know what else happened at a time when, despite what you are suggesting, temperature change was slower than what we seem to be getting now, at ~11.5k years BP? Yup, that's right, a mass extinction.
