meaning gulfstream donald!
serious..
Cobblers!
It means a southerly jet stream and Scandinavian anticyclonic blocking. Hpappened many times in the past. Nothing to do with the Gulf Stream!!
rather well is to do with the gulf stream, weather man mentioned it several times. I wonder if you really mean that the gulf stream moving is nout to do with global warming??? as i beleive (tentatively) that its moved north not south?
The Gulf Stream meanders. Furthermore, it would seem that thermohaline circulations (such as the Pacific Decadal Oscillation and the North Atlantic Meridional) affect our climate a great deal. Far more, indeed than any small amount of CO2 in the atmosphere. It is very difficult to establish the reasons for these changes, since they seem to be associated with solar activity, as well as the fluid dynamics associated with the Earth's rotation and orbit. However, interestingly, there are some who say that the Gulf Stream/North Atlantic Drift is not as important for Europe as claimed:

The jury's out on this. But I personally don't believe, at this point in time, that CO2 has any influence on ocean currents.
:-? a simple yes, in agreement, would have done Nick.
LOL!! Why use one word when ten will do?
But you raise an important point that gets to the crux of the whole issue.
Weather we can all understand - and we all have an opinion on today's weather. Indeed, it used to be the case that the British were criticised for always talking about the weather!
However, weather is, in fact, probably the most complex feature of our planet. Take this, very academic critique of climate modelling:
http://theresilientearth.com/?q=content/climate-models-irreducibly-impreciseThe crux of the matter (backed up by the maths) is summarised at the bottom:
Scientists are currently arguing about temperature changes of tenths of degrees per decade or even per century. Given the state of GCM and available computer resources, valid predictions of climate changes of these magnitudes simply cannot be accurately calculated. This is not a mater of opinion, it is a statement of fact based in mathematical analysis of climate models by multiple scholars. To base the future of the world's economy and possibly the course of human civilization on climate model predictions is insanity. To me, that is why the whole argument about climate change should be approached with caution. The science is highly complex and even the most simple theories are beyond the ken (or beyond the interest!) of most of the public. Hence, fill the media with scare stories and the same general public won't have a clue what is kosher science and what isn't. Tell them that mankind is to blame for all everything from a drizzly day to today's snowfall, and they'll buy it.
Fortunately, dumbed-down education hasn't yet achieved the goal of making everyone like "The Stepford Wives", so there are still a few independent thinkers left that like to examine the evidence.
And when they do......
