A co-founder of Greenpeace told a Senate panel on Tuesday that there is no scientific evidence to back claims that humans are the “dominant cause” of climate change.

Patrick Moore, a Canadian ecologist who was a member of Greenpeace from 1971-86, told members of the Senate Environment and Public Works Committee environmental groups like Greenpeace use faulty computer models and scare tactics in further promoting a political agenda, Fox News reported.

“There is no scientific proof that human emissions of carbon dioxide (CO2) are the dominant cause of the minor warming of the Earth’s atmosphere over the past 100 years,” Mr. Moore said. “Today, we live in an unusually cold period in the history of life on earth and there is no reason to believe that a warmer climate would be anything but beneficial for humans and the majority of other species.

“It is important to recognize, in the face of dire predictions about a [two degrees Celsius] rise in global average temperature, that humans are a tropical species,” he continued. “We evolved at the equator in a climate where freezing weather did not exist. The only reasons we can survive these cold climates are fire, clothing, and housing.
