Tele, you are amazing.

Less than two weeks ago, you posted a very similar message with the sarcastic title "Massive global warming hits Russia". Remember this?

Russia is enduring its harshest winter in over 70 years, with temperatures plunging as low as -50 degrees Celsius. Dozens of people have already died, and almost 150 have been hospitalized.

Astrophool, a professional astrophysicist, replied with a polite explanation of how this phenomenon occurs:

You will see a clear pattern of alternating high latitude anomalies of warm and cold stretching right around the northern globe: extreme warmth from Spitzbergen to Novaya Zemlya to the Kara Sea, off Russia northern coast, but cold on the Russia mainland continuing into Siberia. Then warm in the Russian far east and Kamchatka, but turning very cold again into Alaska and northwestern Canada. Then warm again over eastern Canada up into Baffin and Davis Straits and across Greenland. Averaging over the globe, there is more warmth then cold, and so the net effect is of global warming.

The extremely warm areas all lie north of the extremely cold regions. This is indicative of an undulating (loopy) jet streams that carries warm air north, and in turn, brings cold air from the Arctic south. What this pattern tells us is that more heat is being transported from mid- to high latitudes, and this is one of the classic predictions of global warming. It is also a result from paleoclimate studies: cold epochs, such as the recent Ice Ages, were characterized by reduced heat transport to the poles, while warm climates (such as the PETM 54 Myr ago) were characterized by greatly increased heat transport to the poles.

Despite what people in Moscow or the Yukon may feel, the extreme persistence of this winter pattern (it has recurred now for several winters running) is a probable indicator of global warming. It's a harbinger of global changes to come.

One obvious consequence is reduced Arctic sea ice cover. Just look at the Kara Sea, in the center of the extreme warm anomaly north of the Russian north coast. It has historically been ice-bound for all but 2 months of the year, but which is now, in mid-Dec, still mostly open water.

In addition, Astrophool kindly posted a link to a global temperature map. Anyone looking at this map can see the cold zone located over Russia, Western Siberia, Scandinavia, the Yukon, and yes, even Alaska. Here is the current version of this map:

Perhaps you find it surprising that some zones on the planet are hotter than usual, while others are colder. This may come as a shock, but it is the existence of these local variations which explain why we use a global average when we talk about global warming.

While we are at it, what's up with the two clowns who recc'ed your post? Perhaps they have no short-term memory either.
