Call it the "spotting one cockroach" theory.
Not all scientists are going to be up front enough to say, "It's a difficult line for all scientists to tread, as we need something 'exciting' to have any chance of publishing... to justify our funding."
It has been noted by others that, despite the nod to scientific inquiry, those who adhere to certain lines of thinking seem to have a better chance of being published in some venues than others. This is something, unfortunately, that long predates the global warming theory.
