Sure, you'd think the fact that the overwhelming preponderance of scientist agree that it's nigh upon irrefutable that climate change is real and pressing and a serious threat to the continuation of life on earth would more or less settle the matter—in fact, that it'd been settled more than a decade ago.
What's more, it's tempting to look at it rationally. If climate change isn't real and we make the suggested changes anyway, the downside is...we have a healthier planet. Whereas if is real and we don't, our grandchildren die horrible deaths. So...yeah, that's kind of a no-brainer, if you give it about half a minute's consideration, right?
But if, for whatever reason (Al Gore is fat), that didn't convince me, I think I'd look at who's arguing that it's real and who's arguing it's not. And if Donald Trump is on your side? Is being held up as some sort of expert? The guy who went bankrupt owning a casino—something that is very literally nearly impossible? I think some very serious soul-searching is called for.
So if someday Donald Trump starts yelling about just how great the Beatles were? I think, looking at the guy's history (and his hair), the only logical conclusion is to become a bigger Rolling Stones fan.
(Also, my grandchildren are going to eat your grandchildren, with or without a nice chianti and some fava beans.)
