Ah, Mr Archibald.

You could have heard a pin drop at the Hong Kong conference designed to persuade the airline industry to cut back on its production of so-called greenhouse gases to fight "global warming."
The "Greener Skies 2008" conference had just heard from David Archibald, a solar scientist asserting that climate change is mostly dictated by solar cycles, not carbon dioxide levels, as conventional wisdom suggests.
Archibald didn't just tell the group not to worry about carbon dioxide emissions. He told those gathered they should figure out ways of increasing CO2 output.
"In a few short years, we will have a reversal of the warming of the 20th century," Archibald warned, according to Cargo News Asia. "There will be significant cooling very soon. Our generation has known a warm, giving sun, but the new generation will suffer a sun that is less giving, and the earth will be less fruitful. Carbon dioxide is not even a little bit bad – it's wholly beneficial."
