The truly troubling thing is that an article has to be written on this to try and get through the noise.
"noble cause corruption." It's a term that originated in law-enforcement to describe a dirty cop who plants evidence on a suspect because he "really knows" that the guy is guilty, so he's doing the world a favor by making sure he gets locked up. It's the same rationalization: it's OK to lie, because you're acting in a "noble cause." The corruption, of course, is: how do you really know the suspect is guilty, if you have to fake the evidence against him? How do you know your cause is noble, if you keep having to lie to defend it?
The same thing applies to global warming. If they're so sure their critics are wrong, how come the warmists have to invent evidence to discredit those critics? If they are the heroic defenders of science that they claim to be, how come they have to tear down the very foundation of science in order to prop up their cause?
It is good that more people are waking up to this due to the flagrant violation of scientific ethics this time, but this kind of thing has been going on for years in a more subtle fashion.
