Last night, I was out with some friends around Great Yarmouth and it struck me at how warm it was! It was about 10:00pm and despite my other two mates complaining about the cold, I must admit it wasn't that bad at all. You can usually expect strong North Easterly winds at Yarmouth, and I feel the cold a lot so it must have been pretty mild!
But should we expect warmer or colder winters and why is this? The name 'Global Warming' suggests the former, yet in the short term (the next 50 years) we should all be heading to the shops and buying our wolly sweaters because the Journal of Geophysical Research predicts that the UK will suffer from longer and colder winters. This is mainly due to the fact that as ice ablates in the arctic regions, the heat from the sea water rises into the colder atmosphere, creating effectively a zone of high pressure. Clockwise winds then sweep over the south of the UK and over Europe.
However, in 50-60 years, these cold winters will begin to get warmer. Eventhough there is still a polar air mass circulating over the country, this air mass is getting warmer because of the greenhouse effect.
So Global Warming is the cause of both a short term colder winter and also for the long term warmer winter.
