Patrick Moore, co-founder and former member of Greenpeace, has claimed that climate change is not manmade.
Moore, a Canadian ecologist, told members of the Senate Environment and Public Works Committee that environmentalists use faulty computer models and scare tactics in promoting claims man-made gases are heating up the planet, Fox News reported.
Moore asserted that there is no evidence that human emissions of carbon dioxide are the dominant cause of the minor warming of the Earth's atmosphere over the past 100 years.
Even if the planet is warming up, Moore claimed that it would not be calamitous for men.
Moore added that he left Greenpeace in the 1980s because he believed it became more interested in politics than science, adding that climate change was not an issue when he abandoned Greenpeace, but it certainly is now.
