Because I love to write about climate change and watch the misinformation and noise fly in the comments, I will direct your attention to two very interesting articles about denialism: 1) My friend and noted skeptic Steve Novella writes about the meaning of scientific consensus and denialism, whether that's over global warming or vaccines. 2) An article on lies.com likens global warming denialism to the O. J. Simpson trial, saying that when faced with overwhelming evidence, Simpson's lawyers attacked the court process instead of the actual case. It's a fascinating analogy and one that strikes me as being very apt.
I'll add as a bonus a link to something I wrote a while back: the difference between skepticism and denialism. I wrote it a year or so ago, and don't see anything I would change today.
