Why bother indeed. I suspect that a certain percentage of letters-to-the editor on global warming topics are paid for by fossil fuel companies. 

I'm almost certain that fossil fuel interests pay for blogging on online comment boards and for friendly editorials in places like WSJ and other business-friendly pubs.

This one distorts the case being made for hurricane/global warming links in a particularly clever way, in much the way a professional propagandist would do it.
