Actually they can and will continue to happen, the weather is not some stable thing that is easy to predict. No matter how much money you throw at it, the weather will still cause problems in the future, to think otherwise is to underestimate the complexity of the weather and the chaos it throws up.
Really? Seems to me from all signs from Ian F that they tend to ignore the GFS, so why would they be all confused? They believe it'll be getting colder, every model they place importance in agrees with that.
