Sandy & The Perfect Spin

Scientific American has put up a detailed explanation of why hurricane Sandy may be linked to anthropogenic climate change: a chain of events that, critically, involves the North Atlantic Oscillation nudged towards a negative state by the melting of Arctic sea-ice. On the other hand,   realclimate explained in 2007 that climate change was threatening the Mediterranean region with more severe droughts because climate change would nudge the North Atlantic Oscillation towards a  positive state. The IPCC model suite of 2007 would show these trends  very clearly.

This seems harder to understand than the wave-particle dualism, but the explanation is easy: both arguments  are  realizations of a certain sort of climate noise.
