The fun part about this is that it shows what people actually care about.

What happens if petroleum prices go up? People use less. It's the entire premise of a carbon tax. Fuel costs more so people buy a hybrid or electric vehicle, power utilities find renewables or nuclear more attractive relative to natural gas, etc. In a market economy this is the primary way to get people to switch from something to alternatives -- which is pretty important if you think climate change is a problem.

This is obviously not why Trump is doing it, but it's the consequence of it anyway. So now we get to see what people care about. Do you like higher oil prices because it speeds up the transition away from fossil fuels, or dislike them because of who it is that caused it this time?
