Not sure I understand the question. The claim is: climate change is going to cause big problems in the United States. Your response was: energy is cheaper than ever.
Energy being cheap does not mitigate the problems created by climate change, and there are many scenarios in which low prices make climate impact worse, such as oil prices falling and consumption increasing.
It'd be nice to talk about this stuff in terms of prices because they're very convenient, but convenience does not necessarily make a good metric. The price shout-out is like an ancillary observation at best.
The claim was that among those problems, energy would become more expensive. My counter point is that energy is actually becoming cheaper and while we’re at it, less carbon intensive.
Cheap energy is a great way to solve a lot of the other problems. And lower carbon energy can chip away at the root cause.
Because... that's not true.
