Collapse of Earth's main ocean water circulation system is already happening

Damn, we actually collapsed our environment in the name of profit. This must be the great filter. Its the enticing imaginary bullshit that leads to total obliteration over advancement. The chasing of made-up dragons to make some nonexistent number rise.
- There's a scene in Sagan's Cosmos where he's exploring the possibilities of life elsewhere. He's in the Ship of the Imagination, looking around at various potentials. He runs across one planet teeming with a civilization, from orbit it had even more lights and connections that our own at night. And then the lights suddenly go out. He discusses how even thriving life can suddenly die and speculates on a few reasons why this one might have, like resources or war or whatever. Summary from memory, I have no idea which episode it's in.
  In reality it wouldn't be a sudden disappearance, but a longer decay. The lights shutting off was just to illustrate how easy it is to lose something assumed to be permanent. I'd also recommend the beginning of Revolution to get that same surreal feeling, although the rest of the series was blah.
  
  Ah, Cosmos, I remember watching that when I still believed people were creatures of knowledge and advancement. We'll never know any of those things cause we spent the last 50 years prioritizing profit over all else. It didnt have to be like this.
- I don't believe planet self-destruction is the The great filter, just our filter and we failed. In all fairness it's probably the first of many future filters that would have gotten us too.

The irony of filling up my screen with an advertisement as I try to read about what will be the collapse of our civilization is not lost on me.

So, what does this all mean for us? It means we have even less time to get our act together. Reducing emissions isn’t just a good idea — it’s crucial.
Our planet’s systems are interconnected in ways we’re only beginning to understand. If we want to keep things from getting worse, we need to act now. Every little bit counts, and the clock is ticking.
In other words...we're fucked.
- Well, yeah.
  You were expecting maybe all of the countries of the world to absolve their differences and join hands to defeat the problems of climate change?
  Sounds kinda like a fairy tale.
- Yes, we are likely see the last generation of humans on earth.
  
  We might be able to mitigate some of the effects of we start removing the actual problems people...granted the solution isn't exact 'legal'
  
  We're likely to see a lot of suffering and disruption along with increased mortality, but humans are way too resourceful to go extinct, even with a severe disruption to the climate

But I was told capitalism was the best economic system in the world! Would the capitalists lie to me?
- Close your eyes and think of England....

Great Britain will get more than chilly. Arable land was expected to drop from 32% of the region down to 22% by 2080, slashing their economy by a third. If the AMOC is already showing signs of breakdown, that timeline will need to be shortened.

A weaker ocean current could mean colder winters in Europe and shifts in rainfall patterns that affect millions of people.
Millions? More like billions.

About to be a total Doomer, but I would just like to remind everyone that the current effects we are seeing are due to carbon pumped into the atmosphere 30 YEARS AGO! And emissions have only increased since then.
As a millennial, it's been a hard reckoning that greed and evil truly won before I was born. There was nothing I could ever have done about it. All I can do is just ride it out. In a way, I am privileged. I've always had an interest in history, how fortunate I am to witness it's end.

COP?
COOOP!

Haha, I have no hope left. I might just keep playing league and trash talking my teammates. At least when my mind is filled with hate, the despair can't creep back in :)

Surely the circulation will increase in power and shift to different places. The circulation of water isn't going to just stop, right?
- Yes, collapse here is a fear mongering term, because it makes you think the current will stop without actually saying the word "stop." It's just shifting. Changing. We are in the process of coming out of an ice age. Things gonna be moving.

This only fucks Europe, right?
- “This would bring big changes to the climate and ecosystems, including faster warming in the southern hemisphere, harsher winters in Europe, and weakening of the northern hemisphere’s tropical monsoons.”
  Short answer: no.
  Long answer: nope.

Life on earth:
- Life on Earth will be fine.
  There have been lifeforms that have survived multiple global extinction events over millions of years.
  Humans won't. Which is why I stopped caring anymore about efforts to save ecosystems. Humans don't deserve this planet and will righteously reap what we sow.
  Other life will go "Oh no, humans are gone... Anyways."
  
  Whales, Elephants, and the other Great Apes are all likely to go too, and they don't deserve it. Humans brought this on ourselves, but the loss of peaceful intelligent life is a true tragedy.
