There are now 3 positions in american discourse on climate change: 1. It's not happening / not real 2. It's happening and we can still prevent it 3. It's happening and it's worse than we all think Externalities aren't correctly priced into our market and we're suffering the consequences.
If you can say that, it follows that you have calculated or are aware of the correct price. So, I really want to know - about what is the correct price of the externalities of a gallon of gas that aren't included in, say, the retail price in California? Is it closer to $0.01, $0.10, $1, $10, $100, or $1000?
