He wouldn't read them. I sent him a technical article on computer modeling which explained how designing accurate climate models is essentially not possible. Got a nasty one liner back in all caps. Which is a reliable indicator that I have struck a nerve. The "truth" nerve, the one that really hurts.
The epiphany-of-the-month for me has been, "no one is as dogmatic as a 'free-thinker.'"
If your friend is addicted to snappy one liners, tell him that one of the top climate models (METS model) predicted that in the summer, Ireland and the Central Sahara have the same rainfall.
Betcha that makes him like one liners a tad less. ;-)
