According to my dad:

- there isn't much hard evidence that carbon dioxide drives global warming
- the hockey-stick graph has all kinds of problems with it, especially if you look back over 100,000 years ago
- the left-leaning media (which includes the New Yorker and New York Times) curses too much
- disregarding people when they curse isn't the same as suppressing free speech
- it's better to speak civilly when planning to do terrible things than it is to curse about how we shouldn't be doing terrible things
- when everyone raises their hands for the Green New Deal, that's an example of tribalism on the Left

He thinks Tulsi Gabbard is good, which immediately makes me think there must be something awful about her that I've overlooked.
