The response on CO2 was such an uninformed take I found it hilarious.

Carbon tax is wrong. CO2 is wonderful for plants, trees, and whatever else, and the more CO2 we have, the better the plants thrive, and we need plants, that’s the essence of civilization, if you’d like. If you don’t have plants, you don’t have people. So CO2 is good.

It's like saying "Plants need to be watered, so we need more floods and hurricanes!"
