Indeed. The best available evidence suggests that civilization-threatening (at least) climate change is already baked into the atmosphere and the oceans. Given that humans are effectively incapable of taking the steps that would be needed to -- perhaps -- avert some of the very worst consequences, it's simply not worth arguing with the deniers.
As you indicate, the fuel crisis is going to, once again raise its ugly head, fairly soon, as well. We've had a few years of smug confidence as a result of a large, short-term increase in production of tight oil (and gas) as a result of fracking and horizontal drilling. That's not going to last much longer. Those who doubt that should try a bit of research beginning with googling "depletion rate of fracked wells."
