"We're all going to survive this. It's all going to be a joke in five years," he said. Water vapour was responsible for 95 per cent of the greenhouse effect, an effect which was vital to keep the world warm, he explained. The other greenhouse gases: carbon dioxide, methane, nitrogen dioxide, and various others including CFCs, contributed only five per cent of the effect, carbon dioxide being by far the greatest contributor at 3.6 per cent.
However, carbon dioxide as a result of man's activities was only 3.2 per cent of that, hence only 0.12 per cent of the greenhouse gases in total. Human-related methane, nitrogen dioxide and CFCs etc made similarly minuscule contributions to the effect: 0.066, 0.047 and 0.046 per cent respectively.
"That ought to be the end of the argument, there and then," he said. "We couldn't do it (change the climate) even if we wanted to because water vapour dominates."
===========================================Is this guy correct? I'm not certain, surely not certain enough to castigate all who refute him, which seems to be the attitude of the average American worried that humans are ruining the planet, including the creation of a catastrophic amount of warming.
