Scientific Consensus

In Laudato Si', Pope Francis calls the climate a common good shared by and meant for all, and says, "A very solid scientific consensus indicates that we are presently witnessing a disturbing warming of the climatic system." (LS #23)

Some people disagree about the extent of that consensus, which many cite as at 97%.  But an analysis by James L. Powell, director of the National Physical Sciences Consortium and a member of the National Science Board under Presidents Ronald Reagan and George H.W. Bush, shows that the climate consensus is actually 99.99%.  That would seem to fit Pope Francis' assessment of "very solid."
