The IPCC report was quite equivocal about the hurricane link, so this recent article by Emmanual is actually in line with mainstreaam opinion in the scientific community.
By contrast, in the second study, any result will be less equivocal, i.e., the estimated a posteriori probability will be closer to 0 (so, we are quite sure the hypothesis is false) or 1 (so we are reasonably convinced it is true).
