Scientists: Dona t make a oeextreme colda centerpiece of global warming argument

There are 2 comments on the The Washington Post story from Feb 20, 2014, titled Scientists: Dona t make a oeextreme colda centerpiece of global warming argument. In it, The Washington Post reports that:

It's an intriguing theory - that recently has gotten legs: the melting Arctic - spurred by global warming - is causing the weather's steering flow, the jet stream, to become more extreme.

Agreed. That's why I post this:

but it is incomplete without other indicators such as ocean acidification, species extinction, sealevel rise, etc.

If they do come up with a comprehensive connection between intermittent cold in southern climes & warm Arctic fronts, the connection will have to explain why AGW energy enhanced warm fronts are forcing themselves more frequently into the Arctic NP region.

Often, while cold Arctic fronts are slamming southern populated regions, the high Arctic, over millions of square kilometers, is hanging 12-16degC (22-29degF) above normal high Arctic temperatures...... & that is when the high Arctic has been in continuous darkness for months on end.

Presently, average temperatures of millions of square kilometers of high Arctic have not been of normal temperatures for 95+days, & most often way way above normal.

This present warmth pushing into the Arctic might be considered as a feedback mechanism for AGW. If the warmth had continued in a southern region & remained at its southern temperature, heat would have more readily escaped to space. However, with northward sweeps to the high Arctic, mixing with colder Arctic airs(as well as pushing Arctic air south), a lowering of overall temperature, would delay the overall heat from escaping Earth atmosphere as quickly. Thus, an automatic AGW feedback is created.
