There's a good reason why all the climate change deniers refuse to see human-made climatic change as real..instead they prefer to focus on "global warming" as their whipping boy.
By focusing on one extreme (global warming), it's easier to discount the impact human activity has on the climate as a whole. Rather than seeing the entire weather system as a whole and see the impact on climatic variability as the real issue, their cherry-picking of anthropogenic global warming becomes the easier straw man to tear down.
I've recently been in an argument with a bunch of deniers who, instead of examining the premise of increasing climatic variability (which is the real issue...) they prefer to couch their arguments in terms of global warming ONLY. Why would they do that instead of examining all the evidence?
As anyone who studies vast complex systems will attest: You cannot ignore the resiliency of the system, nor can you over-simplify the system and still have the capacity to understand it to the degree necessary to talk about it intelligently.
Climate is one of the most complicated systems we know of. Reducing it to one aspect (global warming) while specifically ignoring the other aspects (variability and climatic swing intensification) is to deliberately and willfully violate Occam's Razor--which means these idiots are distorting the facts for some agenda.
Why else would they choose to ignore ALL the evidence and ALL the facts and focus on only one area of climate research--to the exclusion of the entire body of work--UNLESS they cannot face the facts or cannot offer anything substantive against ALL the evidence?
I'm reminded of Benjamin Franklin's quote: "We are all born ignorant, but we must work really hard to remain stupid."
These characters remind me of Ron White's quote: "You can't argue with stupid."
