To those who believe that evolution and global warming are settled facts of science, since both topics enjoy the support of the vast majority of scientists, a word of caution. Remember that both terracentrism (the idea that the sun rotated around the earth) and the theory that the world is flat were also topics that were considered settled facts of science, since both enjoyed the support of the vast majority of scientists at the time.
Both ideas are now disproven. My point here is that mankind does not yet know EVERYTHING, despite humanist hubris to the contrary, and both evolution and global warming could be disproven or subsumed into larger hypotheses in the future.
Don't be too proud of what you think you know today...tomorrow you might be wrong.
