Hard to prove a negative from a positive approach! Consensus of scientists, I love that term. To get that “consensus” all they have to ask is: from you study of the history of the planet, has the climate changed? Only a simpleton would answer no so ergo we have a consensus of scientists who say the climate is changing. Beyond that simple note, how many of these scientists agree that the change is directly and solely attributable to man’s activities. When asked that question they should be provided a picture of that little ball of fire in the sky and asked if that little fireball may just have something to do with it.
I think there is a huge % who believe in anthropogenic global warming. That’s because they all have the same professors, read the same books, and won’t get funding unless the work within the ‘paradigm’.
