Still completely clueless, I see.
There's a reason for consensus...the data pretty much speaks for itself. "Consensus" is the result of the research.
In other words, the scientific community doesn't come up with a result, then try to justify it. I can understand that you, in your desperate search for scandal after scandal, would think that it's common practice to come up with the answer to a question before doing the research to confirm it, but that's just not how the scientific community operates.
