Climate change will be considered a joke in five years time, meteorologist Augie Auer told the annual meeting of Mid Canterbury Federated Farmers in Ashburton this week.
"We're all going to survive this. It's all going to be a joke in five years," he said.
"It is time to attack the myth of global warming," he said.
Water vapour was responsible for 95 per cent of the greenhouse effect
The other greenhouse gases
contributed only five per cent of the effect, carbon dioxide being by far the greatest contributor at 3.6 per cent.
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
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."
"It's become a witch-hunt; a Salem witch-hunt," he said.
