The Pareto principle says that reducing CO2 by 80% is doable, but reducing it by 100% will probably destroy us. How much CO2 do you think will be released if we destroy every outdated building and build a new energy efficient one in its place? What’s the payoff time? What’s the cost? The answer I see and hear is often “I don’t care. World is ending. Etc”. This is why I said it strikes me as unserious. I wouldn’t let an intern at my work make such a sloppy suggestion, let alone a politician.

And our climate predictions are just that, predictions. And they can definitely change[1] when you’re talking about geological time, though we often accept them as some sort of gospel.
