The libertarian position on Global Warming is somewhat different. It was well summed up by George Reisman at the end of his 1990 article 'The Toxicity of Environmentalism,' and his position on Global Warming is reprised today by Cafe Hayek:
Let’s assume that global warming is happening and that it’s caused by modern human industry and commerce. Is there a case to be made for the United States government to continue to avoid signing the Kyoto Protocol? More generally, is there a case to be made to shrug our shoulders and say “best not to do anything through government about global warming”?
I think so.
Read on here for the argument that the best way to treat all claims about Global Warming is benign political neglect.
