My opinion on climate change reflects the underlying science involved. I can point to every single scientific organization on the planet and my view on climate change mirrors theirs. My opinion will change as the information available changes. Should new information come to light tomorrow that suggests it is very likely the case that anthropocentric global warming is not occurring, then my opinion would change on that subject.
Contrast that with the PkrBums of the world. His opinion does not reflect the underlying science involved. There aren't any scientific organizations on the planet that agree with the views of the PkrBums out there. His opinion will not change as new information becomes available. Should new information come out tomorrow that irrefutably confirms that AGW is real, his opinion would not change on the subject at all. There is no amount of consensus or new information that could ever change PkrBum's opinion on climate change. Period. None. The conclusion has already been made in his mind. All new information that comes to light that does not support his conclusion will get filed under "massive global conspiracy". What very little "information" comes to light from the fossil fuel industry, AM radio republicans, or a random poll of unrelated "experts" gets filed under "proof that climate change isn't real".
Long story short, there are people whose opinions evolve with the prevailing science and available information of the day; and then there are people whose opinions are simply unchangeable, and are not rooted in reality, science, or empirical observation in any way. For all intents and purposes, their opinions may as well have been extracted directly from their own assholes.
