This stood out to me, too. On the one hand, hearing him say it is a little unnerving. On the other, it's oddly comforting to know that he truly believes we're in a race against the clock to save civilization, and that someone like him is doing everything they can to prevent the end of it (at least on the environmental front; he's probably nervous about other dangers, too, that he'd have less control over, e.g. geopolitics).

Seeing that reaction from him helps explain in my mind how he's been able to accomplish as much as he has. It really feels like he's a man on a mission and that he's going to run through walls to accomplish it.

Other comments have compared him to a politician. I think that's laughable. He has a consistent track record of 'doing.' Politicians have not earned that reputation.
