Calm down, my man.  What happens is that loops in the polar jet stream cause mid-latitude warm air to shoot towards the arctic, something that has happened for millions of years. What happened was that ozone and particulate was swept up and this causes some serious damage to the heat-forcing potential of the arctic zone. While the jet streams are constantly moving, the two polar pathways appears to be off Japan and the US Northeast coast.

True, there may be some increased carbon dioxide in these two (or maybe three) poleward flows. But it is the air pollution from ozone and particulate that is probably doing most of the damage, or is accelerating it in some way. Things are NOT linear with CO2 emission by any means, which is why we can't figure out the rapid loss of Arctic sea ice in the last few years.  And don't tell me about artificial "feedback loops" from some silly model. Ozone and particulate are screwing up the north pole, plain and simple, and the enriched CO2 environment is not helping.

Do us a favor and the next time you see a real solid cold front coming out of Siberia into Alaska and Canada, dropping down into the US mainland, take a look at the water vapor loops on NOAA.  The cold air descends, and hot air shoots up northeast ahead of the front - sometimes as speed of 40 MPH at ground level and much more aloft.  

Here is where is gets worse,  If the Subtropical jet stream is positioned over Texas from Pacific Mexico, enrichment of air pollution from Texas all the way up north past Michigan and Nova Scotia would be really something.  

At the end of the day, what you'll find as being "global warming" is actually a northern hemisphere phenomenon based on these jet streams and cold front cyclones that pump so much air up to the Arctic. I think residual hurricanes also have a major impact.  Note that the Southern Hemisphere and Antarctic has a completely different dynamic - fewer hurricanes and typhoons down there, for example, and much less pollution loading.
