[ExI] cure for global warming is working

The NAO (North Atlantic Oscillation) is pretty cool actually. It is a 
fine example of how the weight of eigenmode can fluctuate. It can be 
modeled rather elegantly as a differential equation driven with noise.

The current ensemble forecasts of the NAO index
suggest that we will be having more nasty winter weather until at least 
middle January.

Most likely it is not strongly climate coupled, according to what I have 
read myself and discussed with the Oxford climate scientists. Not quite 
weather, but definitely not climate either. And since NAO and a bunch of 
the other oscillatory modes are connected in a messy way we shouldn't be 
too surprised by correlated unusual weather.

(OK, time to start preparing for getting out into the Swedish snow 
rather than sit in front of the cozy broadband connection...)
