Stunning ignorance of science is on display by some here.
There is no "scientific orthodoxy". That is just the point of science. Everything is open to question and attack. Theories are born ridiculed, some gain wide acceptance, and often die ridiculed. There is no cosmic answer key. It is only the wide acceptance (by knowledgable people by the way) that determines "truth" in any age. The genius of the climate change deniers is that they have created an illusion that there is not widespread acceptance by knowledgable people. In fact, there *is*. The opposition is almost exclusively non-knowledgable; not necessarily stupid or evil, but certainly outside of their field of training and experience, or holding a very large political or financial stake in the outcome of the debate. Those with true knowledge of the subject and no financial interest are all on one side.
