The lows Tuesday and Wednesday could break records set in 1966. They’ll also feel much worse with wind gusts up to 30 mph, which will make it feel as low as negative 50 degrees, according to the weather service.

Whew boy this isn't supposed to be happening!

Since I call out the AGW proponents for citing weather events as evidence of anything,
I would be remiss to not say that this is simply a weather event.
The appearance of Karma is simply a coincidence!:mrgreen:

Google Maps says I'm 92 miles north of Chicago. I doubt that we are going to see -20°F
But we are getting the snow that's been predicted 1:30PM, started at midnight and it's still
doing it. Tomorrow tells the tale on the temperature claim.

Oops the claim is for Wednesday

Coldest air in decades arrives Tuesday in Midwest with ‘life-threatening’ wind chills
Some forecasts were calling for temperatures to drop to minus-29 in Chicago. The wind chill will fall as low as minus-65 in the Upper Midwest.

Well of course anything out of the ordinary is proof of global warming. Be that extreme hot, or extreme cold, or extended periods where nothing extreme happens whatsoever. :lol:

Really?? Got a link... or even a quote to back that up?

Impossible! AOC said life as we knew it was gonna end soon!

And who is AOC? And do you have anything to back that up as well??

While single week local temps are interesting (note it will be 40 degrees and raining in Chicago this weekend), when looking at the big picture, it’s more important to focus on things like this:

Why isn't it supposed to be happening? The arctic is warming twice as fast as the rest of the world. This causes the jet stream to weaken and swing further south bringing the arctic cold air to the northeastern US.


Warm Arctic means colder, snowier winters in northeastern US, study says

"Warm temperatures in the Arctic cause the jet stream to take these wild swings, and when it swings farther south, that causes cold air to reach farther south. These swings tend to hang around for awhile, so the weather we have in the eastern United States, whether it's cold or warm, tends to stay with us longer."

That’s because of anthropogenic warming.

Or did you make that connection all on your own?

Right. Because of anthropogenic warming.

Who said that? That cold air is straight from the North pole and it is warmer than Chicago now. That is a predicted consequence of global warming that results from a weakening of the polar jet that normally keeps arctic air bottled up at the poles.

 

[iguanaman]

Right. Because of anthropogenic warming.

Which weakens the polar jet stream and allows arctic air to descend south with greater frequency. There I finished it for you.

Darkness at Noon by Arthur Koestler.:roll:

Research suggests that this reduction in the temperature difference is robbing the jet stream of some of its strength, making it wobblier and contributing to more temperature extremes.
The jet stream is strongest in winter, when it has the greatest effect on weather in more densely populated parts of North America and Eurasia.
When it rolls along in relatively steady waves, normal weather ensues, with spells of cold, snow and intermittent warm-ups.
But when it coils far to the south, bitter cold Arctic air spills southward along with it.

LOL You have no clue how jet streams get their power.

But how does the temperature difference between two air masses cause the jet stream? Since colder air is more dense than warmer air, there is an air pressure difference between them at any altitude. And if the warm and cold air masses are quite deep, higher altitudes in the atmosphere experience progressively larger air pressure differences.

Since it is horizontal air pressure differences that cause wind, this leads to very strong winds. But at some altitude high in the troposphere, the temperature difference reverses, and as you progress higher the winds then decrease. The altitude at which the winds were strongest is considered to be the jet stream level.

So, the strongest jet stream winds then occur between air masses having the largest temperature differences over the deepest layer of the troposphere.

What causes the jet stream?
