Not shockingly, I agreed with all he said but explained that there's actually another reason to be against pulling out of the Paris Accord which might resonate even more with his Republican and/or still-Trump-supporting friends than icky science, research and facts, because it on a far-more prosaic level. I heard it discussed by a Congressman earlier today, and it's very basic --
By pulling out of the Paris Accords (if we do...), the United States loses the moral leadership on Climate Change. And this is a massively growing industry for the entire world. As such it will be other countries -- including China which has already begun a major investment in the field -- who take the leadership in developing alternative energy solutions. There will be no special reason for other countries to look to the United States for technology in what is clearly a growing international industry. That means lost jobs and lost leadership in the next big technology.
