I just saw in two or three other threads that some people here are claiming that the scientist Mann "lost his own court case and apologized to the person he sued for questioning him" or "the court ruled in favour of this published scientist being named a fraud".
Whatever one thinks of Mann and his graph, the truth is that the court did NOT rule in favour of him being named a fraud; the case never even got to court. Mann did NOT apologise to any defendant, and in fact one of the defendants publicly retracted their claims about Mann and apologised to him - see below.
As I said, whatever you think about the person and his graph, no one should throw around lies around like this. If the case against climate science is strong, you shouldn't need to BS about it.
