The potential collapse of a key Atlantic ocean current − due to human-caused climate change − is in the news again.

You’d be hard-pressed to come up with a scarier scenario than what’s going on now with the “Atlantic Meridional Overturning Circulation (AMOC),” the fickle Atlantic ocean current whose weakening and eventual collapse could change the climate and weather for hundreds of millions of people.

A pair of new scientific studies detail the present and potential future of the AMOC, which was the ocean current at the center of the fictional (and scientifically inaccurate) “Day After Tomorrow” climate change disaster movie in 2004.

In one study released April 8, scientists at the University of Miami determined that over the past 20 years, the AMOC has already been weakening at four different locations in the Atlantic. In the other study, released April 16, a separate group of European scientists said the AMOC will weaken by 50% by 2100, potentially eventually leading to its “collapse.”

A weakening AMOC means the Atlantic Ocean’s climate‑regulating currents slow down over a period of a few decades, while a collapse means the entire current system crosses a tipping point and mostly shuts down − triggering abrupt, potentially irreversible global climate disruptions.

    No government is going to do anything about something happening after the year 2100.

    If I’m not mistaken, the movie posited that the temperature collapse is happening faster than we think and accelerated to collapse all at the same time.

    The estimate is 2100 but that’s just an estimate. Reality is that it could happen at any time.

    Sorry, but why would we not use the name AMOC and instead call it the “22 year old movie current”?

      What about “Aging Movie is Ominously Current” or AMOC for short?

        So I guess we’ve just completely given up on how to use acronyms and abbreviations. I’ve noticed that a increasing amount of people will just use them without explaining it, they just expect others will either already know what it means or will do a search and figure it out. As a non-native English speaker it drives me up the wall. I find my self asking what a acronym/abbreviation means at least once per week, sometimes multiple times a week.

        I thought that explaining the acronym on the first use, and then using it as is was the common and courteous way to use them, WTF (what the fuck) happened to that, I do wonder.

          As a native English speaker, I concur with your feelings on the matter. I absolutely hate when someone does that and sometimes I won’t even bother to finish reading what someone wrote if they just start using acronyms all willy nilly. Hell, you can’t even point out spelling errors or grammar errors anymore without upsetting someone.

    I remember The Day After Tomorrow, it was an okay film but it solidified in me the fear of climate change. The movie may not be scientifically accurate, mainly because they got the temperatures backwards. In the movie, the world froze starting at the poles. IRL, it’s going to boil and burn starting from the equator.

      Iirc that’s already started. All the growing zones have moved further north or south from where they used to be when I was a kid (back in the early 60’s).

        Oh yeah I’ve seen it myself. I’d like to move up north to get ahead of it, but there’s national lines to get across and taking my pets would be difficult at best.

        I’ve also been noticing that since I was a kid (90s/00s), back then there was a white winter every singe year in my area. Now we’re lucky if we get any snow at all during winter.

        Then I’ll hear some rube say that ‘global warming isn’t real,’ like what bitch?! Have you not been paying attention?!

      While that is true. If the Atlantic ocean current stops, the poles will freeze, and start a new ice age in northern Europe and North America, while also boiling the equator.

    The cycle keeps northern Europe several degrees warmer than it would otherwise

    Collapsing this current should be part of EU’s climate goals. If we can’t stop it, lets accelerate it.

      Remember that one time the temperature in Europe dropped by around 1.5 degrees and it lead to mass starvation and migration? Imagine that, but much worse and without it going back to normal after a while.

      Even if it would work and Europe is fine, it’s still a dick move to do that to the rest of the world. As well as mass migration from hard hit places into Europe leading to an overall bad time for everyone.

      But you are kidding right? Right?

        Fuck em. They can lower their emissions it they want to prevent it. The army will solve mass migration issue.

        (of course I’m kidding but I would like to see how Americans would react to this idea)

          If you’re looking for a bottom to American idiocy, you’re going to be disappointed. No low is too low and no ignorance is left uncelebrated.
