It is extraordinarily tempting for even a (generally) ethical person to twist or “mislay” data when he KNOWS something is TRUE.
We see this in cops and prosecutors who frame up a person they KNOW is guilty.
The temptation is no doubt even greater when there is a religious level of belief, when they see the conflict not between accurate and inaccurate, but between Good and Evil.
Of course, scientists aren’t supposed to look at issues in this way, since when they do they by definition stop being scientists.
Perhaps this story will eventually play out to show that scientists are also people, and are as prone to human failings as anyone else. So we shouldn’t elevate a scientist’s opinion that much above anybody else’s.
The belief in man-caused global warming has become a religion. Scientific method doesn't matter.
