Let us assume that among qualified climate researchers there is a very small percentage that are politically or financially motivated to reach a certain conclusion. For the sake of argument, let's assume that it is 10% on each side of the man-made climate change argument. About 95% of all qualified researchers come down on the side that our current climate change is unprecedented in its rate, and that it is caused by human activity. About 5% disagrees. If we take away 10% from each side, we get 86 out of 100 believing that our current climate change is unprecedented in its rate, and that it is caused by human activity. We get only 4 or 5 out of 100 disagreeing.
The sound bet is with the 86, and against the 4 or 5 outlier researchers.
