There is now strong evidence to suggest that the unusually cold winters of the past two years in the UK are the result of heating elsewhere. With the help of the severe weather analyst John Mason and the Climate Science Rapid Response Team, I’ve been through as much of the scientific literature as I can lay hands on. Here’s what seems to be happening.
The global temperature maps published by NASA present a striking picture. Last month’s shows a deep blue splodge over Iceland, Spitsbergen, Scandanavia and the UK, and another over the western US and eastern Pacific. Temperatures in these regions were between 0.5 and 4 degrees colder than the November average from 1951 and 1980. But on either side of these cool blue pools are raging fires of orange, red and maroon: the temperatures in western Greenland, northern Canada and Siberia were between two and ten degrees higher than usual. NASA’s Arctic oscillations map for December 3-10 shows that parts of Baffin Island and central Greenland were 15 degrees warmer than the average for 2002 to 2009. There was a similar pattern last winter. These anomalies appear to be connected.
... I can already hear the howls of execration: now you’re claiming that this cooling is the result of warming! Well yes, it could be. A global warming trend doesn’t mean that every region becomes warmer, every month. That’s what averages are for: they put local events in context. The denial of manmade climate change has mutated first into a denial of science in general, now into a denial of basic arithmetic. If it’s snowing in Britain, a thousand websites and quite a few newspapers tell us, the planet can’t be warming.
...just look out of the window. No explanation of the numbers, no description of the North Atlantic Oscillation or the Arctic Dipole, no reminder of current temperatures in other parts of the world, can compete with the observation than there’s a foot of snow outside. We are simple, earthy creatures, governed by our senses. What we see and taste and feel overrides analysis. The cold has reason in a deathly grip.

Global Warming and the Weather!!
For those climate change deniers, and there are many of them, can I suggest they read George Monbiot's excellent article on the link between global warming and the current Arctic weather conditions that we are enduring. This is how George seeks to explain the link:
