This page kind of assumes the audience is already willing to admit social cooling as a legitimate phenomena, and if not, will be convinced to do so after a few short bullets and very little in the way of actual analysis (ironically, this sort of approach leverages one of the modern patterns the piece could tackle--short bursts of information, instant delivery, decreased skepticism and amounts of reflective thought).
Also, I'd highly recommend avoiding the global warming comparison. It does a disservice to your cause. It basically comes off, at least to me, as saying "our problem isn't a substantial thing in its own right so lets compare it to this other big problem people already care about and hope the very loose and forced analogy strings them along"
All this being stated, ya'll should check out Horkheimer's essay "The Concept of Man." He wrote it in ~1952(might've been 53 or 57, I'm forgetting the exact date)--and it's crazy how prophetic that essay turned out to be. It shows how all our innovation really just led to an amplification of social structures and patterns that were already emerging during the dawn of automation and mechanization. I think it's relevant to your project.
