Historic "climate change" in the arctic approaching, is on the move.

Yes- you heard that right- a "climate change" event is taking place around the North Pole as we speak. Supposedly, a new set of weather patterns taking place in the arctic are calling for temperatures to soar above freezing. Wait- there's more! The temperatures in the arctic will soar a full fifty degrees Fahrenheit- above average. You know what?... This reminds me of something... an event that happened here in the United States in recent times, at least a couple of years or so back in time. What happened was that there was a radical change on the way during the winter. And this change of weather pattern was initially affecting only the far eastern reaches of Russia, in Siberia. And, on the contrary, there were still record breaking lows in temperature that winter, and these extended as far down south as the gulf states! So, what exactly caused these weird climatic anomalies? Well, in the first place, this was initially a single weather pattern, that would eventually turn into a dual weather system! This may sound pretty strange, and I will explain how this came about. The first, initial weather pattern that prevailed was that of an unusually strong warm front, that would venture its way through Siberia. This is not what we consider a "heat wave", because those are associated mostly with the warmer months. However, as for the time of year- late December- during which time all of this started- this would still be considered by many as a heat wave. Just not in the same sense that it feels like spring, per say.----As a result, the polar vortex, which, as it's name suggests, originates in the Arctic regions of Earth, responded to this change in climate. So, as the incredibly persistent warm front just keeps pushing, trying to make it's way further and further towards the arctic, at the same time, the polar vortex is being forced out of its place. This change in weather patterns is especially noticeable later on, in North America -especially parts of the lower forty eight, particularly in states such as New York, Wisconsin, Minnesota, North Dakota, Michigan, Ohio, as well as several other states; although this change was not noticeable for some time. But why?...
Well, first of all, the polar vortex will not have immediate effects on the American climate here in the United States. This is because the polar vortex takes time to travel all of the way down across Canada and make it's incredible journey into the lower forty eight. As a result, the cold spells that invaded the United States did not come until some time in January. And because of the extended duration of time that the vortex stayed in place over the United States, that would eventually bring about ever more frigid temperatures...
...throughout that same winter, temperatures in the United States would plummet down, even as much as fifty degrees below average. This was probably no more noticeable in any other state as much as it was in Minnesota. This is where the temperature even got down to several degrees of subzero. As a matter of fact, on the border between Canada and the United States, a record reading of negative forty degrees Fahrenheit was measured!

Please explain this to me in the Celcius Language. Can you do that?

Why, yes. I was talking in terms of Fahrenheit. I'm so sorry if that is not what you would like to hear. What I was telling them is just the fact that there is a temperature difference of approximately thirty degrees Celcius or so. And to be exact, imagine such a scenario; in this scenario it is forty degrees Celcius outside. That is a scorcher for most all of us! Well, actually, let's just suppose that this is your average temperature for the time being. Now, in order to find out what a temperature change has occurred, then your result comes out as...  ten degrees C. Wowwww, Huh?!
That is as though we were stuck out in a place like say, Arizona during the summer. Let's say we are in Vegas. Or the Sahara; although it is "only" about a hundred degrees; that will be our starting point. The next thing you know, it is only fifty degrees outside! And then again, is this a fair comparison?
