The Greek Freeze

The Global Warming brigade were wailing into their cornflakes this week as a particularly harsh spell of winter weather hit parts of Europe. For example Greece was hit by heavy blizzards with deep snow drifts that cut off many villages and brought flights to a standstill in the Greek capital Athens. Indeed some areas of Greece saw temperatures as low as -12 degrees Celcius, and renowned holiday beaches that normally throng with summer vistors were deep under snow.

Elsewhere there were also conditions of heavy cold throughout much of Central Europe, and even southern Italy was hit by particularly low temperatures. Meanwhile there were also frigid conditions for the British Isles with some places registering temperatures as low as -10 degrees Celsius.

But why should any of this be remarkable? After all the northern hemisphere is still in winter and cold and icy conditions are only to be expected. Well right. But if one took the theories of Global Warming at face value then these episodes should be impossible: They should not be happening, but they are. In plain language it means that if areas of even the Mediterranean can still get as cold as this then Global Warming just isn't happening. No way Jose!! I mean what are we to believe? That sometimes the heat trapping clouds of carbon dioxide just fade away and make the planet feel a little colder sometimes? If so then where do these clouds blow to?

The reality is that global temperatures in any given area depend very strongly on the wind direction rather than any more sinister explanation. In the northern hemisphere when the wind blows from the north the weather becomes cold. In the case of the recent Greek freeze this was simply the result of winds that plunged down across Russia from the Artic Circle, bringing a deep freeze to most of northern Europe. Similarly the frigid conditions in the British Isles were the result of swirling wind patterns of a predominantly northerly orientation. Either way it confirms a healthy seasonal trend that if Global Warming were really happening would never occur.
