Polar vortex: The science behind the cold

Science | 207394 hits | Feb 07 10:16 am | Posted by: DrCaleb

The polar vortex, a swirl of low-pressure air six miles up in the atmosphere, blasted much of the American Midwest and Northeast in late January 2019 with temperatures cold enough to bring on frostbite within minutes.

We used to call this phenomenon "winter"

Now we call it undeniable proof that the world is too hot.

Because heat is why I'm freezing my balls off when I go outside. I'd go full Hikikomori is I didn't have to work in the winter months.

Yup. If it weren't so hot you wouldn't be so cold.

I'd always be hot... and I'm cold as ice.

So, which part of the article disagrees with your data?

This bit here:

Increasing carbon dioxide in the atmosphere cools the polar stratosphere, which could increase the temperature difference between the pole and the equator and strengthen the polar vortex. There's also some model evidence that the waves that are propagating upwards in the troposphere are getting more energetic as the planet warms, leading to a more perturbed polar stratosphere.

doesn't so much "disagree with data" as point out they don't actually have any.

Notice the word "could" and how they all of a sudden are using a "model." A model is supposed to express what the data says not create the data.

Also, explain this one too me:

"carbon dioxide in the atmosphere cools the polar stratosphere"

Where does that come from? What data shows that? Sounds hypothetical.

True...I thought that CO2 was the mystikal magikal molekule that radiated heat all on its own.

As usual though, he's completely wrong.

Complex models of the atmosphere show that increased carbon dioxide (CO2) concentrations, while warming the surface and troposphere, lead to lower temperatures in the stratosphere and mesosphere. This cooling, which is often referred to as “stratospheric cooling”, is evident also in observations and considered to be one of the fingerprints of anthropogenic global warming. Although the responsible mechanisms have been identified, they have mostly been discussed heuristically, incompletely, or in combination with other effects such as ozone depletion, leaving the subject prone to misconceptions.

CO2!! It HEATS!!! It COOLS!! It CAUSES CANCER!! It CURES CANCER!!! It WIPES UP SPILLS AS IF THEY NEVER EXISTED!!!

I don't understand why that's hard to believe. CO2 absorbs more of the reflected heat off the earth and warms the troposphere (closer to the ground). Since less heat is making it out of the troposphere, since it's being absorbed by CO2, the Strato and Mesosphere cool off.

So then why argue with us when we taunt you folks with the argument you just reiterated that global cooling is caused by global warming and that it's cold outside only because it's so hot?
