How did the royal society get their winter warm weather predictions so wrong?

Less warming is predicted, for example, over the North Atlantic Ocean. Climate models tend to predict that precipitation will generally increase in areas with already high amounts of precipitation and generally decrease in areas with low amounts of precipitation."

Virtually everybody that lives near the North Atlantic has experienced record breaking freezing winter weather for the last three years so how can The RS make such a big mistake? Is there something wrong with the computer models that predict these weather patterns?
