Da plane! Da plane!
It's been suggested that the grounding of North American flying machines following the Sept. 11 attacks helped show the effect aeroplanes are having on global warming.
Theory has it that aircraft leave vapour trails that turn into clouds. Clouds deflect sunlight back into space, keeping the Earth cooler than you'd expect it to be. And Aussie scientist Tim Flannery
that as the skies cleared post Sept. 11, the northern hemisphere's temperature went up by a couple of degrees.
Planes are helping mask global warming. It's all just hurting my little head.
