We sit in the nice warm Gulf stream. If Global warming rises to such an extent that the tides and weather patterns change, the nice warm Gulf stream will divert to lower down. Instead of washing up over the west coast of Ireland, Scotland and Southern England/Wales, it will go either, straight up the channel into Holland or further down to Portugal, which, as I'm sure people will agree, has more than it's share of nice weather.If that happens, coinciding with the general lower temperatures that happen every 50 - 100 years, we will end up as frost bound as certain Canadian provinces. The south-west will become a haven for all manner of wildlife that is driven south by the bitter northern winters and the wildlife we have already will in turn be pushed farther south to France and Spain where it will probably be shot and eaten.
Mind you, it would be fun to have a frost fair on the Thames again....
