New next level science unlocked.

The titty of the polar vortex sags ever southward.

HawlSera ,

So that’s why that is

JustinAngel ,

I’m a climate idiot. Does this somehow relate to ice ages, I wonder?

Ice ages typically happen due to very low insolation or the ability of solar energy to reach the surface of our planet. Insolation is a term often used when describing how much energy a solar panel can create.

Right now we have a big problem with too many greenhouse gases, which exacerbate the insolation we already have. It is heating our oceans rapidly, thus causing the break up of ice sheets in the Arctic and Antarctica. At some point the oceans won’t be able to absorb the heat we are receiving and air temperatures will begin to rise as well. Equilibrium. Hence Venus by Tuesday.

So maybeish, so there is the possibility that warming of the oceans will cause the large ocean currents to slow/stop. This will reduce the amount of mixing of ocean water. Causing greater salinity and temperature gradients in the oceans relative to latitude. Making the Arctic ocean colder and the tropical ocean warmer. This colder Arctic ocean would lead to lower Arctic temperatures and an increase in ice, increasing the albedo of earth. The higher albedo would reflect more sunlight cooling the planet into an ice age.

Having said all that it is important to note, first if this happens it will be on geologic time scales. So the planet will still get a lot hotter first. Second it is just a hypothesis, we don’t know what is going to happen on a longer scale because this period of warming is unprecedented in earth’s history. Yes it has been hotter and had higher CO2 levels, but not anywhere the speed of chance we have had in the last 100years. So using past trends to predict the current change will be vague at best.

TLDR: it is still going to get a lot hotter before any chance of getting colder.

Tlaloc_Temporal ,

Correct me if I’m wrong, but this warm ocean leading to cold poles is one of the suspected mechanisms that cause repeated glacial/interglacial periods in ice ages, right?

Everythingispenguins ,

That is my understanding, though I don’t know the details of the process off the top of my head.

psud ,

We are in an ice age, you can tell because there is an ice cap at both poles.

We are in an interglacial period, which if we fixed carbon pollution today would still continue for tens of thousands of years beyond it’s expected end

There used to be a theory that this sort of weather reinforces the northern ice and glaciers and could start glaciation, but that’s not supported by modern models

Not even a shitpost

TokenBoomer OP ,

Define “shitpost.”

No.

havokdj ,

Toilet humor. That’s literwlly what a shitpost is. I enjoyed seeing this post on my feed but it definitely belongs in a different community

TokenBoomer OP ,

The sidebar says “Anything and Everything.”

havokdj ,

Oh, I’m sorry, did c/lemmyshitpost coin the term “shitposting”?

/b/ is “anything and everything” too, there’s no rule against porn there, but that doesn’t necessarily mean it belongs there though does it?

TokenBoomer OP ,

I wasn’t aware you made the rules. Now I have to rethink everything.

havokdj ,

You know the rules

And SO do IIIIIII

TokenBoomer OP ,

A FULL commitment’s what I’m thinking of.

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

Al Gore and many others said there wouldn’t be any ice at all in the polar regions by 2013.

Obviously climate change it happening, but the computer models they keep showing have been proven to be bullshit over and over.

ChewTiger ,

Doesn’t mean we can’t learn from them. The process of developing those models can be incredibly useful in learning about complex steps. They help us understand what conditions and variables are important to look into. We can figure out what we know a lot about and what is still a complete mystery.

Turbulent airflow is an incredibly complicated thing, we still haven’t fully solved the Navier+Stokes equations. I hope to be alive when someone does.

Just because they don’t perfectly figure it out the first time doesn’t mean we should stop putting effort into incremental improvements. Though we do have to be careful that we are not wasting resources when there is a more efficient path forward. Simulations are one of many important tools, we just have to use them wisely.

Whatever benefits you get out of letting an AI write code for you, is lost as soon as the corporate overlords claim your work as theirs because they own the AI that wrote it.

Funny that this post would show up next to this one: lemmy.world/post/10902481

TokenBoomer OP ,

Good stuff.

Tristaniopsis ,

Ahem…. Shouldn’t that be ‘fewer’ ice?

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.”

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.
