Well, given the fact that you refuse to accept any source that doesn't agree with you as credible, I've been reviewing the 2014 IPCC report looking for their estimate of the cost of fighting global warming, and can't seem to find one.  Maybe you can point one out to me.  https://www.ipcc.ch/publications_and_data/ar4/syr/en/mains5-7.html

But I owe you an apology.  I was dealing in hypotheticals.  The fight against Global Warming isn't going to cost us anything, because we aren't going to fight it.  We've pulled out of the Paris Accords and we're reigning in the EPA's excessive regulations.  Trump called it a hoax, and apparently the voters agreed.  Sorry you couldn't make the sale.  Better luck next time.

Meanwhile, you might want to think about preparing for colder weather.  Of these ten scientists who refute global warming, 5 say it's already getting colder.
