are you harping on the climate change thing because you disagree that's its important or because you believe he overstated the immediacy of the danger?

The immediacy thing. I think we need to reduce economic externalities as much as possible and eventually to 0, but even the most dire warnings from legitimate scientists puts the world at 50% uninhabitable (by land area) at around 2300 (earth is currently about 25% uninhabitable). More than likely not, any such terrible outcome wouldn't be for hundreds more if not thousands of years.
In actuality, warming will produce positive outcomes for most if not all of the 21st century. The "ideal" temperature of the planet as best we can figure is about 2 degrees C over pre-industrial levels. We're halfway there and should reach that number somewhere late 21st century. Things will only get worse than present time when we get to about 3 degrees C over pre-industrial levels, which won't happen until next century some time.
So yes, it's something we need to study much more and we need to take the right steps to not fuck up the planet, but we're far from that point and acting like chicken little about the issue and ignoring reality makes this guy a crackpot.
