New Scientist debunks the 26 most common myths and misconceptions about global climate change, ranging from “It’s all a conspiracy” to “Polar bear numbers are increasing,” “The ‘hockey stick’ graph has been proven wrong” to “Global Warming is caused by the sun.” These myths are utterly wrong, and easily shown to be so.
