The fact that they do enormous damage to "Science," in the abstract, is of very minor consequence to them. They don't really care about "Science" in the abstract, because they're not good enough scientists to really contribute to it. Look at that boob Michael Mann, the Penn State University "researcher" who sold himself to the global warming hoax. He's really not a scientist at all, but he gets to pretend he's one, and his department head goes along with it because he brings in the bucks. But history will forget him, while remembering names like Newton, Watt, Ampere, Joule, and many others.
If you want a great example of this in the world of diet and obesity, read Gary Taubes’ new book, “Why We Get Fat.” Basically, it’s global warming with proteins.
