    Robust Weakening of the Gulf Stream During the Past Four Decades Observed in the Florida Straits https://doi.org/10.1029/2023GL105170

    Plain Language Summary

    The Gulf Stream is a major ocean current located off the East Coast of the United States. It carries a tremendous amount of seawater and along with it heat, carbon, and other ocean constituents. Because of this, the Gulf Stream plays an important role in weather and climate, influencing phenomena as seemingly unrelated as sea level along coastal Florida and temperature and precipitation over continental Europe. Given how important this ocean current is to science and society, scientists have tried to determine whether the Gulf Stream has undergone significant changes under global warming, but so far, they have not reached a firm conclusion. Here we report our effort to synthesize available Gulf Stream observations from the Florida Straits near Miami, and to assess whether and how the Gulf Stream transport there has changed since 1982. We conclude with a high degree of confidence that Gulf Stream transport has indeed slowed by about 4% in the past 40 years, the first conclusive, unambiguous observational evidence that this ocean current has undergone significant change in the recent past. Future studies should try to identify the cause of this change.

      The consequences are unpredictable. More extreme weather is about the only certainty.

      The energy of the heat transfer will not just be missing in Europe. It’ll also be in excess in the Caribbeans, perhaps creating stronger winds worldwide.

      Imagine a house with water radiators, where you turn off the circulation pump while keeping the furnace on full blast. It’s gotta go somewhere.

        Maybe the warming and freezing will cancel out and the much smaller islands that will be left after the sea levels rise will still be temperate and worth living on.

        Edit: This is not an “I’m alright, Jack” comment. I’d rather this wasn’t even a vague possibility and that the planet wasn’t warming out of control.

          Maybe, but food and water will be extremely scarce. We can’t all just up and move. You and I will almost certainly die of starvation.

        So’s Norway - quite a few places on the west coast (the most inhabited non-Oslo part of the country) rely on the fact that the gulf stream keeps them unusually warm for their latitude

        I’m already seeing things that would normally grow fine out in the garden suffer from abnormally late and early frosts and mild summers. Rip my tomatos and onions. Everyone’s complaining about 20+ degree springs in the mainland while I’m screaming that it’s still snowing in late May.

          Oof, I’m sorry to hear about your veggies :(

          I hope it doesn’t collapse, it would mean a lot of displaced people and loss of life.

      East coast of Canada and US will become arid. Caribbean will become hotter and storms will become more severe. Scotland, Ireland, Iceland, and Norway will be substantially colder (compare latitude of UK with Northern Canada) and with less precipitation. Basically, everywhere that relies on warm tropical moist air currents will drastically change.

      Europe is at the latitude of Canada, it lacks Canada’s climate gradient because of the Gulf stream

      We 'bouta see Siberia stretch its way to the Elbe!

      What will be the consequences to this?

      It will have to be renamed to the Gulf Trickle.

    Oh well, we had a good innings there didn’t we?

    Still, I’m in my 40s now, so if it doesn’t completely collapse for about 50 years or so I’m pretty sure I won’t have to worry about it.

    Seeing this, i kinda hope that it happens as fast as possible. That way the rich will see exactly what they’ve done, and maybe we’ll manage to get some revenge

      Yeah, force the rich to see all the poor people dying from their ivory towers. I’m sure they’ll suddenly start worrying about other people’s suffering.

        Ivory towers are still capable of being seiged

        Many governments have fallen over the years because they forgot that they only have a thin veil of control over their people

    Is this not the only tipping point that can actually reduce energy held by the biosphere due to increased ice in the northern hemisphere, and therefor increasing Earth’s albedo?

        A Parisian expert in French literature failed Quebec’s “French Proficiency Exam”, not to mention how other languages don’t get anything close to the pedestal treatment English and French get under Canada’s official bilingualism. One of Trudeau’s cabinet was subjected to quebecoise nationalist mistreatment because she spoke an indigenous language instead of French.

        And BTW, I’m saying that as someone of Quebecoise descent, likely pure laine as recently as my grandmother.

          Your response was a relief; as the emoji I posted was indicating, I was worried it was some frothing about pronoun preferences having some legal protections.

            Nah, I just think official language status is a violation of free speech, and of the natural development and evolution of culture.

            I mean just look at France and Quebec in contrast, motherland French and Quebecoise French are nearly separate languages from each other with how incomprehensible they can be to each other, and yet both Quebec and France have strict prescriptivist official language policies in place supposedly in the name of “preserving the French language.”

            If there was any sort of naturalness to any of it they’d rigidly have maintained the same exact language with all the same linguistic conventions, and yet that has not happened at all, debunking the supposed entire point of this farce in the first place.

            The only reason to maintain it at this point is that it excludes the lower classes from public office and official spaces, since they are the most likely to diverge from a prescribed cultural structure, and you can see that in Ontario where francophones raised riot when funds were beginning to be allocated for the language support of Indian and Chinese languages that actually had more speakers within Ontario than French did. It’s not about preserving a minority language, it’s about refusing the rights of immigrants to have their languages accommodated as well.

        Boi you’re the one who just decided to go to bat for anti-immigrant, anti-indigenous, and anti-working-class official language statuses and unofficial taboos against monolinguals or “wrong” bilinguals in state representation.

        Either that or you’re a dumbfuck who didn’t read the rest of the thread and decided you wanted to pop off anyways about some unrelated grievance completely separated from this conversation like the dumbfuck doing that would make ya, dumbfuck.
