Antarctic sea-ice at 'mind-blowing' low alarms experts : worldnews

[–] [email protected] 43 points 11 months ago

Dr Caroline Holmes at the British Antarctic Survey explains that the impacts of shrinking sea-ice may become evident as the season transitions to summer - when there's potential for an unstoppable feedback loop of ice melting.

Even modest increases in sea levels can result in dangerously high storm surges that could wipe out coastal communities. If significant amounts of land ice were to start melting, the impacts would be catastrophic for millions of people around the world.

Buckle up kids, this ride’s about to get bumpier.

it never ceases to amaze me how stupid we all are as a civilization.

we're opting out of it, but nature will continue. this will be a very curious and fairly hospitable world full of interesting xenoarcheological mysteries... in the distant future, to a visiting spacefaring civilization.

[–] [email protected] 25 points 11 months ago (2 children)

You have to wonder if we aren't just confirming what the Great Filter is. There may not be any space faring civilizations.

[–] [email protected] 19 points 11 months ago

Seriously, that’s what I’ve been thinking recently - that we’re hitting the self-destruction theory of the Great Filter.

I've said it before, and I'll say it again, planet gonna planet. It give zero fucks about us and will happily continue spinning long after we are gone. If civilizations get purged along the way makes no difference. Kinda makes the "evil villain" from Kingsman: The Secret Service right that we are the virus.

"The end of the world" (I can't believe I have to explain this) is a euphemism for humanity being wiped out or at the very least the end of the planet being habitable

You know what's most depressing? Statistically people reading this comment (people who have access to computers/phones + the internet) will have little to mild effects of climate change, compared to the BILLIONS that will perish. Humans will survive all this, but at the cost of unimaginable suffering from the silent/silenced poor.

[–] [email protected] 22 points 11 months ago (3 children)

"Humans will survive this" - I am unconvinced, I think there are very real reasons to consider the coming climate variations as an existential threat.

[–] [email protected] 15 points 11 months ago* (last edited 11 months ago) (1 children)

My new nightmare is that we manage to kill off oceanic algae and the rainforests and most us oxygen-breathers just all slowly collectively suffocate to death. Probably at a rate that we know it’s coming for humans at a certain point. Scientists would probably be able to predict it down to the week. So us humans all see our fate and are just patiently waiting for our death as we watch all the smaller mammals perish before our eyes.

[–] [email protected] 6 points 11 months ago

In this scenario I think the largest mammals will go first? Like if you consider there was a higher concentration of oxygen during the dinosaur era and some dinosaurs were really big. So it seems larger mammals might need a higher concentration of oxygen.

[–] [email protected] 3 points 11 months ago (1 children)

Difficult to predict the future, anything is likely. But my point was if humans do survive, it'll only be the priveleged few. Even in the last days of humanity, those who have the means will survive longer

[–] [email protected] 2 points 11 months ago (1 children)

Well, sure, the super-rich might think they can buy their way out of the global warming apocalypse right now, but when the proverbial excrement meets the oscillating appliance, I doubt their stacks of cash will make a great umbrella. Imagine their surprise when they're left high and dry, clutching their last bottle of water in a world that values survival skills over bank account balances. It'll be a chilly reality check for them, and I can't help but wonder who'll be eager to assist former wealthy folks when their wallets no longer do the talking. 🌎💸😉

[–] [email protected] 4 points 11 months ago

I always find this "money doesn't buy you happiness" argument really strange & pointless. In your scenario where are the rest of us? Dead & gone a long long time ago. There's little meaning in having the moral high ground when we're all dead.

What I feel gets overlooked a lot is money equates to capital & opportunity. Their "stacks kd cash" have real power right now. They can leverage just the existence of that to do what they want. Take Elongate Muskrat as a prime example and how he bought his website keeping stock as collateral (not even selling it).

Which makes its extremely important to not leave the rich with their money. Now is when that money actually has value, we need to tax the ever living fuck out of the ultra rich and start thinking about saving as many people as we can.

I also understand I am part of the 1-5% of the world's population and am ready to pay and make others like me pay as well. And I am definitely not alone.

Humanity will survive this but everyone will suffer the effects. Even something relatively minor like COVID had great effects to the global economy, but with these we are talking about:

Weather inestabilization, with greater storms and massive heat waves.
General crop failures in many places of the world.
Desertification in many areas.
Massive migration waves.
Very difficult and unstable economy.

We are starting to see some of this, but 2050 onwards is going to be a very difficult time for all humanity except the most wealthy.

[–] [email protected] 9 points 11 months ago (1 children)

So you're saying there is a deadline to eating the rich?

... Noted...

[–] [email protected] 3 points 11 months ago

I bring the mustard...

[–] [email protected] 16 points 11 months ago* (last edited 11 months ago)

If it gets bad enough that millions die, let alone billions, the effects will hit everyone, hard. Sorry to burst your bubble, but the economy is very interconnected and fragile, and wars are started over a lot less.

[–] [email protected] 36 points 11 months ago (2 children)

It's happening so fast now... I always thought we would have more time

[–] [email protected] 29 points 11 months ago (1 children)

I actually did think it would speed up like this.

...but not for science reasons, it's just, I know from defrosting the freezer that it does not melt at a steady rate but gets faster and faster.

[–] [email protected] 10 points 11 months ago

I mean, that's pretty scientific training right there

[–] [email protected] 18 points 11 months ago

So did the scientists. Stuff is happening now that wasn't supposed to happen until the 2070s.

[–] [email protected] 18 points 11 months ago (5 children)

look this is going to sound horrible but -- i was born in 1996, i've been hearing this shit all my life, climate catastrophe, uninhabitable planet....i'm just waiting for a spectacular collapse so i can stop having the background anxiety about it and we can live our lives like in our favorite post-apocalyptic films

[–] [email protected] 11 points 11 months ago

Unfortunately, large-scale systems change slowly due to inertia and the distances involved. Unless you introduce extreme amounts of energy like the dinosaur killing meteor.

Even then it's happening ridiculously fast considering changes of this scale typically happen over tens of thousands of years at least.

[–] [email protected] 8 points 11 months ago (3 children)

Yeah!

We're all gonna be in this apocalyptic film

[–] [email protected] 8 points 11 months ago

If there is enough civilization to have film after.

After the fall of the Mediterranean Bronze Age civilizations, it took several hundred years before any real civilizations arose. And the only one with any records of it were the Egyptians

[–] MustardCabbage 5 points 11 months ago

And even though I can't explain it, I already know how great it is...

[–] Aurenkin 4 points 11 months ago

Uhh, well ... not all of us. Wouldn't be much of an apocalypse otherwise

[–] [email protected] 6 points 11 months ago (2 children)

God yeah. This is like a tease that has been happening for decades. I cannot wait to normalize living in bunkers.

[–] [email protected] 13 points 11 months ago* (last edited 11 months ago)

You all need to lower your expectations. Billions of people are going to die.

[–] [email protected] 2 points 11 months ago

All the bunkers in my part of the world are owned by Silicon valley billionaires/Russian oligarchs.

Toss it on the fucking pile of shit that's unfixable at this point.

[–] [email protected] 15 points 11 months ago (1 children)

Well.. it was nice knowing you all...

[–] [email protected] 4 points 11 months ago

It was n(ice) while it lasted

[–] [email protected] 8 points 11 months ago

This is the best summary I could come up with:

The sea-ice surrounding Antarctica is well below any previous recorded winter level, satellite data shows, a worrying new benchmark for a region that once seemed resistant to global warming.

Antarctica's huge ice expanse regulates the planet's temperature, as the white surface reflects the Sun's energy back into the atmosphere and also cools the water beneath and near it.

Dr Caroline Holmes at the British Antarctic Survey explains that the impacts of shrinking sea-ice may become evident as the season transitions to summer - when there's potential for an unstoppable feedback loop of ice melting.

As more sea-ice disappears, it exposes dark areas of ocean, which absorb sunlight instead of reflecting it, meaning that the heat energy is added into the water, which in turn melts more ice.

There are signs that what is already happening to Antarctica's ice sheets is in the worst-case scenario range of what was predicted, says Prof Anna Hogg, an Earth scientist at the University of Leeds.

At the scientific base Rothera, Dr Mallet is using radar instruments to study sea-ice thickness for an international research project called Defiant.

Tell me more

[–] [email protected] 11 points 11 months ago* (last edited 11 months ago) (1 children)

This is a good explanation.

Look this up yourself with other sources though too. You'll want to fnd out how much ice coverage is left at the poles, how much we've lost this year so far, and the loss projection for if the next 5 years are as hot as 2023. Then look up what will happen to the earth with all the unreflected solar radiation we'll be absorbing without the ice caps.

[–] [email protected] 2 points 11 months ago (1 children)

Well that is terrifying

[–] [email protected] 2 points 11 months ago

Yup. And with all the wildfires releasing a shit ton of carbon into the atmosphere alongside all the shit released from industrial pollution, the next few years are very likely gonna be hot as fuck.
