Good news/bad news re climate change

So a British research team (the Hadley Centre for Climate Prediction, and an Oxford guy) came up with a new method of weeding climate prediction models. Their innovation: use the models to 'predict' observed conditions, weed out the ones that get it wrong. They figure this should significantly tighten up the quality of the modelling, and thus reduce the uncertainties. That's the good news.

The bad news is the now more certain predictions are also rather scarier.
