Gray: we're not to blame

THE United States' leading hurricane forecaster says global ocean currents, not human-produced carbon dioxide, are responsible for global warming.

William Gray, a Colorado State University researcher, also said the Earth may begin to cool on its own in five to 10 years.

Speaking to a group of Republican MPs, Dr Gray had harsh words for researchers and politicians who said man-made greenhouse gases were responsible for global warming.

"They are blaming it all on humans, which is crazy," he said.

"We're not the cause of it."
