Mmmm, no, don't think so.
You do know that Sochi is a Black Sea summer resort which has palm trees? << psst, palm trees will die in prolonged sub-freezing temperatures.
Nope, didn't think so.
What happen this winter season is that the polar cold was diverted by a flex in the jet stream, that sent the greatest surge of cold over the Western Hemisphere, while what would have been the normally frigid winter that usually has encompassed the Sochi region was diverted at just a critical time for the Winter Olympics.
The greater picture is much more defined than it has been made out to be, but most people cannot see further than what is going on in their own street.
Greenland is probably actually getting a more than average increase in their seasonal ice coverage. But northern Siberia is not.

I saw a great article the other day by a climatologist (believe it was posted on this site) that said the sun, which provides all the external heat on earth, is in a decline that will likely lead to a mini ice age. When the sun's energy lowers, it affects the earth's jet stream causing large north/south elliptical sweeps across the planet. These huge swings lead to extremes, such as we now have in the U.S. with California baking and the rest of the country in a deep freeze.

Actually Sochi has winters more similar to Atlanta than Lake Placid. It was an odd choice for a winter olympics.

Justa is right. Sochi is a summer resort. It was a place where the proletariat went for “sanatorium”. It was chosen for political reasons. See the above link with videos. . Its an eye opener.
