Many papers.

No. He says he reads ‘all the papers’!

Speaking of cherry-picked data, this is from your link: "compared to a baseline average from 1951 to 1980"

There is a reason why they chose that particular time period. Had they included the years 1915 to 1950 they would have included record high temperatures. Much higher than today's temperatures, with 1936 being one of the hottest years this past century.

That you do not have any evidence that the severiorty of the storms themselves has increased says it all. You don't have it because they have not done so.

How does that change the increase in destructiveness? Answer: not a whit.

The northern jet stream never reaches the Arctic Circle, which makes it impossible for the lower-48 to experience Arctic cold.

And yet, that is exactly what happens when a polar vortex occurs and are becoming more frequent as the Arctic has been warming more rapidly (2-3x faster) than other regions of N. America. That warming disrupts the jet stream and allows cold arctic air to escape southward.

The Chinook Winds blow for about a week to 10 days. Like I said before, they normally occur in January, but when they occur in December or February is not that unusual.

If you weren't so keen on cherry-picking your propaganda, you would have noticed that Nome had a high temperature of +7°F on December 5th, before the Chinook Winds began to blow.

The Arctic has warmed 2-3x more rapidly than any other place on earth as this chart showing the the steady loss of Arctic sea ice over the past 40 years:

Why do you think this -9 F is such a big deal? because some blogger told you?

Don't you verify this stuff before posting?

Nome's averages 15 to 30 F low to high in the end of October. Do you have a point?

It's not about just Casper's lowest low, it's about the increasing incidence of these polar vortex displacements which are a direct result of rapid warming of the Arctic relative to the rest of the planet. Here's the explanation for that (not the we'll expect any valid scientific explanation will have the slightest effect on the cult mentality of CAGW denial):

2) A growing body of research links rising Arctic temperatures with extreme winters
The Arctic is warming two to three times as fast as the global average. Scientists say warmer air temperatures in the Arctic can weaken the polar jet stream, a west-to-east river of wind where cold Arctic air meets milder subtropical air in the mid-latitudes of the Northern Hemisphere. A strong jet stream typically traps the polar vortex over the Arctic, but when it’s weakened, the cold air can stray southward into the United States.

The impacts of a warming Arctic on mid-latitudes is a rapidly emerging field of scientific inquiry. There have been some significant scientific findings in just the past year:

Warmer Arctic linked to U.S. winter extremes: Scientists have strengthened our understanding of the link between a warmer Arctic and the frequency and changes of U.S. winter weather, especially cold spells and heavy snows in the Northeast and upper Midwest. While previous studies only looked at a few months’ or a year’s worth of data, authors of a recent Nature Communications study analyzed data stretching back to 1950. They found a strong relationship between warm Arctic temperatures and severe winter weather east of the Rockies, especially in the eastern United States.

Warmer Arctic linked to Eurasian winter extremes: Researchers have now confirmed a pattern of colder winters and more frequent cold air outbreaks in Siberia, following sea ice loss in the Barents-Kara seas in late autumn. In another study, scientists found that over the past 37 years, weakened polar vortexes happened more frequently, allowing frigid air to escape the Arctic. This helps explain cooling trends seen in mid-latitude Eurasia.

Warmer Arctic linked to prolonged extremes: Scientists have now established a link between Arctic warming, sea ice loss and more persistent weather patterns in North America. When weather conditions get “stuck” and last for many days—a phenomenon caused by altered wind circulation patterns—they can cause prolonged and damaging droughts, cold spells and heat waves.

Tough Times For Climate Alarmists

Arctic sea ice growth so far this month has been the fastest on record, and ice extent is nearly “normal.” It is going to be difficult blaming this year’s winter weather on missing Arctic ice.
