Re: Arctic temperatures soar 25 degrees above normal in the dead of winter
#2Anecdotal:
Here in Toronto, it's been 16˚C this past week. In February. We've had about 2 or 3 real snowfalls that stuck around for a few days before melting.
As somebody who loves ice skating outside, it's really frustrating. And I love the snow.
Every year it seems like the winter gets a little milder...

#3Didn't the same happen last year, with arctic polar region being warmer than sub-arctic latitudes? Maybe it's the new normal climate or at least semi-persistent like El Niño?

#4Using events like this to illustrate that global warming is happening is about as scientifically significant as when Trump used the recent US cold snap to imply that global warming isn't happening. I'm not saying climate change doesn't exist--it certainly does--but outlying events like this aren't by themselves particularly unusual. "Normal", after all, is at the top of a bell curve, and deviations from normal should be expected.

#5How much statistical significance can have an anomaly that lasts only 24 hours?

I don't know global warming is happening because of this news article. This news article worries me because I know global warming is happening.

Isolated abnormal events aren't significant to illustrate global warming is happening, but an increasing frequency of abnormal events is.

Suppose you know for a fact that this place has never experienced such an an event like this over the last x years with x a large number. Furthermore you have strong evidence the Earth is warming. Then this happens. Such an observation can be significant. It depends on the situation. I don’t know if this event qualifies. I don’t know enough but someone who studies the issue made the tweet. To his trained eye this was noteworthy. Not proof but noteworthy.

#9Note that this is in Celsius - for us Americans, this is 45 degrees Fahrenheit above normal.

The scientific significance of these two events (Arctic warming and the recent US cold snap) is not comparable. If you would like more information, you can start by referring to the wikipedia article on climate change in the Arctic [0], and the skeptical science page on why cold weather isn't evidence against global warming [1]. There are numerous other publications available online which discuss these issues that I'm sure you will be able to find.
