Why is it important?

Communicating the consensus on AGW has been shown to be effective in correcting a deliberately manufactured public misconception that doubt among climate scientists is widespread. However, there is still a very small, but well publicized, minority of scientists that dispute AGW, however incoherently and it is important to both acknowledge and rebut them.
