Advocacy: Heartland Institute conference attendees try for a subtler skepticism, but group's leader sometimes strays off message -- 05/23/2012 -- www.eenews.net

Still, the attendees reflect a range of skepticism that can differ by degrees.

James Taylor, a lawyer and a Heartland senior fellow, said it is unclear if the sun, clouds or carbon dioxide is having a primary effect on atmospheric changes, but added, "Just because temperatures are rising, doesn't mean it's bad."

William Gray, an emeritus professor of meteorology at Colorado State University, said he believes carbon dioxide emissions could increase global temperatures by 0.3 degree Celsius over the next century or so, which he says is about one-tenth of the increase projected by mainstream scientists.

"Humans aren't doing it. It's the most ridiculous thing," Gray said. "This is not going to cause any problems for the world -- slightly more warming. Now, if it went up 3 degrees, yes, I would be worried. Perhaps a lot of things would change."

Eleven Degrees Global Warming And Global Cooling | Real Science

NRDC says that temperatures will warm eleven degrees by the year 2100

...Eleven must be sort of a magic number for eco whackjobs, because in 1970 they forecast eleven degrees cooling by the year 2000.
