Since when does one (roughly) side of a controversy deserve much more examination and aspersions as to whether they are "bought" or not than another? Does anyone seriously believe the pro-AGW folks all are totally un-invested scholars speaking only pure objective truth as they best see it? Give me a break.
Everyone that has some doubt about the official AGW story or claims has been roundly vilified for quite some time now. They have been compared to flat earthers or young earth folks for bothering to voice an opinion. This is not the stance of any sort of enlightened discourse or inquiry. It is a concerted effort to silence and shame critics of a politically aligned position. It has almost nothing to do with real science.
