The reason for the predited cold Winter in the central parts of the UK is an abnormal variation in the North Atlantic Oscillation (NAO).
That really is about climate change. The NAO is one of the strongest determinants of Winter weather in the UK.
If the NAO becomes unstable, or moves, (as this research suggests), that adds to the eidence that the climate is changing (as opposed to some unusual weather).
