Ted Turner has lost his mind:

If global warming isn’t stemmed, “we’ll be 8 degrees hotter in 30 or 40 years and basically none of the crops will grow,” Turner said during PBS’ “Charlie Rose.”

“Most of the people will have died and the rest of us will be cannibals,” said Turner, 69. “Civilization will have broken down. The few people left will be living in a failed state … living conditions will be intolerable.”

Needless to say, there’s no scientific basis for the nightmarish scenario that Turner describes. And he’s certainly not alone; plenty of enviro-fanatics have offered similarly hysterical warnings. My favorite example of this is the claim by Mike Archer (Dean of Science at the University of New South Wales) that the sea level might rise by 100 meters. That’s utterly impossible; according to glaciologist Nikolai Osokin, even if every bit of ice in the world melted, the sea level would only rise 64 meters.

My question is this: do the environmental fanatics make such ridiculous claims because they are so delusional that they actually believe their own fantasies? Or are they knowingly lying because they think it’s an effective way to promote their agenda?
