Yep that’s a shit post alright

climate.gov/…/understanding-arctic-polar-vortex

As of 2021 the science was not settled on the ice loss as a cause or an affect. This article goes into both theories.

Krauerking ,

Interesting. I would love to work on that kind of data model, as there is an interesting thing to point out with the movement of the polar vortex:
It dips further south to follow along land mass.

I wonder if the wind currents have an easier time maintaining speed along flat surfaces or if the water being warmer causes pockets of higher pressure further north than usual pushing the vortex to be more unstable looking.

It feels like it makes sense that the current would be much more stable along a surface that is more consistent and thus loss of ice smoothing the surface would cause it to wobble but inertia still remains the same meaning it needs to push down elsewhere where there is less resistance.

So I would lean towards ice loss as a cause of changing polar vortex stability but I kinda gave up that ability to do anything about this or study such things a while ago.

That’s a bit like the investigation into whether lethal bear attacks are because of their teeth or their claws - probably really interesting, but not critical to the question of avoiding the bear.

Iampossiblyatwork ,

This made me laugh.

Kusimulkku ,

But a fair point when someone says it’s due to one as part of their argument

Slovene ,

I was led to believe it’s both. Global warming causes ice loss which contributes to global warming which causes more ice loss which contributes to global warming which causes more ice loss …

Seems too simplistic

Sagifurius ,

I mean, I’m really doubtful when this is what used be considered a normal winter.

Tlaloc_Temporal ,

A normal winter started in October, maybe mid November, not early January. This was my first brown christmas, and that worries me.

cashews_best_nut ,

More fibre and less Christmas pudding.

Sagifurius ,

Dunno where you are, but i’m high desert. Brown christmas and a january ass kicking is pretty standard, admittedly seemingly more common when i was younger. . Even half of canada gets a brown christmas every ten years or so, pretty much on this pattern.

Tlaloc_Temporal ,

Smack in the middle of Canada, winters colder than Alaska, summers nearly as warm as Hawai’i. We already get very little rain, and like the rest of the Great Plains, we’re on track to being a desert (temperate in our case). We already lost most of our topsoil in the dirty 30s, and there’s plenty of sand just below in the glacial till.

I’d rather that not happen.

Sagifurius ,

I run a bar in SW Saskatchewan. Do I know you? Tompkins Hotel. You sound like a Frontier dirt farmer bragging

Tlaloc_Temporal ,

Nah, just your average citiot, though I know a few who worked in PA.

duffman ,

Record temperatures are not the norm.

Sagifurius ,

These aren’t records, fuck off. “OMG MINUS 38 WINDCHILL MINUS 52” It used to be 50 on a calm day these areas, mid january, dead calm. There’s a sensationalist aspect occurring over what people old enough recognize as normal weather.

HawlSera ,

So that’s why that is

Sagifurius ,

“let’s pretend we don’t understand La Nina and El Nino during this cyclical winter to push our current agenda. Anyone says “WTF” we brand as a science denier.”

Earth’s just gotta drink more if its stream is weak. I mean that’s what I do

Slovene ,

We should also pour cranberry juice into the ocean.

LemmyKnowsBest ,

OMG does our jet stream pass through a UTI too??

6buck6satan6 ,

Too many people do not understand the difference between weather and climate.

Sagifurius ,

And often, the people who laugh at “boomers” saying shit like “What global warming?” in weather events like this, don’t acknowledge or comprehend they’re doing the same damn thing, from the opposite perspective.

mechoman444 ,

HEY!!! Get your science and facts out of here!

~ Places fingers in ears and closes eyes ~ laalalalalalalal

WoahWoah ,

I would tell this asshole to shut his stupid mouth, but my teeth froze together. I’ve got one finger left still working. Help me…

And also, it’s usually way colder than this here, and while it’s frigid, I’m fine. Happy even. I live in one of the parts that is supposed to be cold, and this is a nice regression to normal.

Tristaniopsis ,

Ahem…. Shouldn’t that be ‘fewer’ ice?

For being so smart, we are so dumb

themeatbridge ,

It’s not just that we’re stupid. We’re also selfish.

PunnyName ,

Many are proud of their stupidity.

And their selfishness.

Huge difference between raw intellectual capacity and exercised utility.

You can have a 10 gallon bucket, but it’ll only carry that much water if you fill it.

Kingofthezyx ,

We think we are smart enough to get away with it.

Don’t worry, the Earth will heal >!once we’re gone!<

Great, but what is the “Great Plains” and how is it affecting me?

CaptDust ,

In the United States, the Great Plains is the large stretch of land east of the Rockies, it contains parts of 10 states: Montana, North Dakota, South Dakota, Wyoming , Nebraska, Kansas, Colorado, Oklahoma, Texas, and New Mexico. It also extends up into Canada.

betheydocrime ,

The “Great Plains” is where a lot of your food comes from, and humans must eat food in order to survive

prettybunnys ,

And the southern US is where a lot of our produce comes from in the winter BUT now that they are losing the consistency of the jet stream maintaining milder temperatures they are seeing crop failure due to hard freezes they otherwise wouldn’t even have to contemplate worrying about.

We do not even know whether @obinice is from the US.

For those wanting to know, this Wikipedia article explains what area the name refers to.

betheydocrime ,

Fair enough, I definitely need to work on not centering America in my view of the world, and a quick check of their comment history shows they’re from the UK
