Because of these pig-ignorant people, any scientific finding that doesn't correspond to the dominant scientific paradigm becomes "another nail in the coffin" for that paradigm. That the tsunami that struck Hawaii didn't manifest as a 300-foot-tall wall of water is, for such luminaries, further proof that scientists simply suck at predicting anything that involves heightened sea-level. They leap from a televisually disappointing tsunami to stock global warming denialism because they believe a single failure undermines an entire enterprise, i.e. they have no understanding of or investment in the scientific method.
Like I said: it's depressing.
