Ready for the next Ice Age? Winter is coming.

Meanwhile in the real world...

Well, first off, those are wind chills, which are excellent for exaggerating and scaring people.

But, setting the numbers aside, that picture quite accurately shows the problem. The Northern Hemisphere is still warm enough that the polar vortex didn't form properly again this year. It's not supposed to wander around this far south. Cooling is not the problem, it's warming. Meanwhile, the actual Arctic is well above average, still.

Wind chill is a measurement of the rate of heat loss from your body when you're exposed to low temperatures combined with wind. Researchers in Antarctica developed the measurement to estimate the severity of Antarctic weather. You can compare the severity of one storm to another by comparing the wind chills, the combination of temperature and wind speed generated by the storm

The Arctic consists of an Arctic ocean that mostly surrounded by land. As such, the climate of much of the Arctic is moderated by the Arctic ocean water, which can never have a temperature below −2 °C (28 °F). In winter, this relatively warm ocean water, even though covered by the polar ice pack, keeps the North Pole from being the coldest place in the Northern Hemisphere and the reason that Antarctica is so much colder than the Arctic.

The climate of Antarctica is the coldest on Earth. Antarctica has the lowest temperature ever recorded: −89.2 °C (−128.6 °F) because the pole is over land

It is the combination of few hours of daylight solar flux absorption in the winter and a long winter night of clear sky's ( no cloud cover, cold dry air ) allowing heat radiation back into space that allows the ground temperature to reach that of near space, This means the solar vortex is always unstable at the north pole and wants to shift a nearby landmass where colder temperatures can be reached

Which is another way of saying the Arctic didn't get cold enough this year to hold the vortex. Exactly my point.

Well, yeah. It's winter. But it isn't like super winter or anything. If anything, it's still been a really mild winter, so far. I'm what would be about under the bottom-left point of the R in Detroit's -57 wind chill label, right on the Detroit River coast, just north of the mouth of Lake Erie. And last weekend was the 2nd snowfall we've had. There was nothing but a dusting in fall-winter 2018. That's really a late winter start, even for around here. Up until the last two weeks, when the vortex wandered it's way in, we were averaging a good 10 degrees above normal.

And there's always a big hubbub about the first snow and first cold snap of the season. And, honestly, this is it. According to a couple days ago's reports on the weather channel, I should have about a foot of snow accumulation right now. I can show you the 2-3 inches on my grass, if you'd like? (Although it might be somewhat solid, as it was 35 yesterday and partially melted it before it all refroze into a solid block of frozen treacherous terrain.

Its a good laugh to joke that I could use some warmth. But, in all honesty, the past few winters have been an eye-opening show of the normal winter progression breaking down.

We've mostly skipped winter in BC. The blob came back in the autumn - sea surface temps 2-3 degrees C above normal. It takes more than 3000 times the heat energy to raise a cubic meter (1 tonne) of water by the same temperature as it takes to warm a cubic meter of air the same amount.
The blob has dissipated to a certain extent now - maybe around 1C higher than normal at the moment. Your cold North East isn't freezing me in the North West.

Look in the mirror when you state this.

Every year you do the 'look, it's cold in one place so that proves it's not getting hotter'. The depth of the fallacy it pointed out each time but it leaves no detectable trace on you. It cannot be that you have not heard it, so it may be that you have not understood it. Can you tell me why it is that I would say that a few cold days in one place on the earth doesn't disprove a rising global temperature? Are you able to state the argument that I would make?
Once you have done that, if I agree you have formulated it correctly, then you can go on to show me why that argument would be wrong.

It's summer in the Antarctic right now. It's also a bit warmer than usual in the Arctic - a bunch of their cold air has gone missing ... wonder where it went.

Exactly. The Arctic wasn't cold enough to properly hold the polar vortex. Hence it wandered off, down into the Midwest again this year. It's not that the world is getting colder, it is that the Arctic region is getting warmer. At a glance, it looks counter-intuitive, but if you dig a little bit into actual facts and physics, you see it is absolutely the case.

WHOOOAAAH!
Steady on there, pardner!
Facts?
Physics?

That's crazy talk and will never catch on round here.

Now, let's get back to discussing how it's all a Chinese Hungarian hoax designed to steal American jobs and somehow involves collaboration with the Nazis.
:p

On a *slightly* more serious note:
It is so cold in Chicago they’re lighting railroad tracks on fire
A wavy jet stream is to blame. (And climate change may be, too).

The Arctic is only cold enough to hold a polar vortex in the Summer, in the winter the polar vortex always wanders to the land surrounding the arctic ocean
