Why no hoopla in climate circles?
The MetOffice's few-month "predictions" have been so lacking in accuracy that you would think they would be pounding on IBM's door begging to be allowed to buy this technology. After all, it can supposedly accurately predict weather conditions in a small location (that's even harder than doing it for a big region) a month in advance!
My guess is that both the MetOffice and IBM realize this is just sales droid fluff, and since they would only be ripping off the Chinese if their statement turned out not to be true there's no skin off Britain's nose.
