See the difference there is that you don't need shallow feel-bad articles about climate change. There's hard science there; it's incontrovertible.

In contrast, neurotically wringing our figurative hands about imagined problems like the link between vaccines and autism, the link between video games and school shootings, or disintegration of traditional values in modern times; all without hard science backing it up; will continue to fail to convince all but the most blinded.

And whether the problem is "new" or a few decades old is really irrelevant.

Why should we think it's not tens of thousands of years old?
