Is this one of those "either / or" situations that are mutually exclusive?

[ken goes into his "method" Limbaugh-right mode again]
Everything is black or white, us or them. The world is much more simple that way. Now if only good would win outright... Oh, and if you disagree you are either part of the conspiracy or are a dupe of that conspiracy. Only I and those who think like I do know the truth. You would see this if you 1) were as smart as I am 2) would stop believing/watching/reading the liberal media 3) would open your eyes to common sense 4) would realize that your "education" was an indoctrination as a "useful idiot" in the atheist/Communist/Socialist/liberal/[your boggy-man of the day here] conspiracy to destroy all that is good and right in the world.

Guess you will have to ask Hansen that since he is the one who excluded the sun.

False - the NASA-GISS model does include the sun.
