Question either of these and you're worse than Hitler: CO2 causes Atlantic hurricanes because it nudges the NAO *negative*; CO2 also causes Mediterranean droughts because it nudges the NAO *positive*

Die Klimazwiebel: 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.
