I'm not sure what a global
cooling trend is supposed to mean, Quote:
"I think if we continue the cooling trend a couple of more years, the general public will at last begin to realize that they've been scammed on this global-warming thing."
Unless cooling is a local effect. I know it was cold back east this year. It was warm in ND again this winter, as we escaped the usual cold of the '90's. The global average has apparently been warmer.
According to these links we still have overall global warming:

John Coleman doesn't seem to understand how the greenhouse effect works. He doesn't think a little bit of CO2 will make a difference. (Coleman said.
"So how can that tiny trace compound have such a significant effect on temperature? "My position is it can't," he continued.) But that's really the whole point of the effects comparison to a greenhouse, how a
very thin sheet of glass can trap heat in the entire structure underneath it. Greenhouse glass could be much thinner than it normally is and still work very, very effectively except it would be too fragile.
With glass, one can try an experiment where one faces a warm radiant fireplace and then temporarily shields ones face with a pane of glass. The glass easily allows high frequency visable light through ...but largely blocks lower frequency infrared heat radiation. The difference can be felt on the face as the heat is blocked by the glass.
In a greenhouse, the visable sun light travels through the glass and is reduced in frequency after it strikes a surface. The new lower frequency, which is now merely heat energy, cannot easily re-radiate back out of the glass and is therefore trapped in the greenhouse ...or earth ...as the case may be.
I think Fox news tries so hard to present some alternate views, views that are not generally found in main stream media, that it's especially important to take various info from Fox with a grain of salt. They don't necessarily endorse
all the stuff they print ...but they do make an effort to present alternate views to the reader, the reader to make up their own mind, a choice I appreciate.
