This is one of the scientists on the Global Warning Swindle documentary. I've have chosen a statement by him, written on the Royal Society website, on the basis if Martin Durkin trusts him to put him on his own documentary then he must be one of the **honest** scientists and not one of the **swindlers**.
And yet, what Carl Wunsch argues is that although there is no absolute certainty that there is a "very high probability" of "human-induced" climate change and that policy has to be made on probabilities not certainties!
"It is very difficult to separate human induced change from natural change, certainly not with the confidence we all seek. In these circumstances, it is essential to remember that the inability to prove human-induced change is not the same thing as a demonstration of its absence. It is probably true that most scientists would assign a very high probability that human-induced change is already strongly present in the climate system, while at the same time agreeing that clear-cut proof is not now available and may not be available for a long-time to come, if ever. Public policy has to be made on the basis of probabilities, not firm proof." - Carl Wunsch
