Tropical Forcings

In total, at least four studies, two based entirely on analyses of observations, and the other two based on climate model simulations, independently come to the conclusion that warming tropical Atlantic and Pacific SSTs (sea surface temperatures) cannot be purely attributed to any natural oscillation. These studies do not conclusively show a hurricane/global warming link, let alone determine what it's magnitude might be, but they do strengthen one pillar of that linkage.

Sounds right to me. Taking a human-made bellows to natural climate sensitivities is the case in point. That's what we are doing. Hot enough for ya?
