It’s been a long-time suspicion of mine that doomsayers of whatever persuasion (and there’s an endless variety of such) are driven in no small measure by an anticipation of Schadenfreude.  Though they’ll typically deny it by cloaking their prognostications and divinations as “concern” for humanity, I reckon they really, really, really do want some or other disaster to befall others—the bigger, the better—so that they can proclaim, “See?  That’s what you get for not listening to me!”  In this view, then, it’s no surprise that they’ll seize on any old mishap that affords them an opportunity to blow their own trumpet.  And here we find anthropogenic climate change to be a convenient scapegoat in wolf’s clothing.
