This was a terrible, very nearly statistics-free article (beyond one hand-wavey figure about possible future migration by 2100). It had about as much relevance and impact as stating that mounting fears of dog bites cause some to rethink living in neighborhoods with dogs. It's not even interesting as two case studies, if that was what it was attempting. This article was pure drivel.
That said, count me as one who is migrating due, at least partially, to fears of climate change, from a low coastal region further inland. There are other, and weightier, factors involved in the move, but climate change rendering my current town uninhabitable in the next few decades is one of them, and an important one. I would love to see the article this should have been, examining polling, statistics, and drawing possible inferences.
