Blast From the Past

(Fox News) - The man credited with convincing former British Prime Minister Tony Blair about the dangers of global warming — now says green activists are actually hurting their own cause. Media reports say former chief scientific adviser Sir David King claims environmentalists are — "Keen to take us back to the 18th or even the 17th century."

King says the only way to beat global warming is by relying more on nuclear, wind, and other power sources — and use genetically modified food. He says aviation has been unfairly scapegoated — and that many attempted fixes by environmentalists just make things worse.

But King's contentions were dismissed by the head of Greenpeace, who says it is King who is living in the past.
