A very accurate drought prediction?

Climatologist Who Predicted California Drought 10 Years Ago Says It May Soon Be 'Even More Dire' | ThinkProgress

It's not so often that some modelling work seems to have made such an accurate predication, but in this case, the 2004 work seems to have been very close to the mark.

Tamino has a post on the same issue (it's via him that I found the Romm article), taking to task NOAA's Martin Hoerling, who has written that there is no evidence of global warming being behind the Californian drought.

I have noted for years that NOAA has been prominent in issuing quick denials of connections between  AGW and extreme weather.  I'm not sure if Hoerling is the one who has always been behind this policy; I would have to search back a bit.   In any event, as I have argued before, dismissing connections too quickly is not a very sound approach in something as complex as climate and weather.
