What would happen if the Gulf Stream did collapse? Would a different similar circulatory system emerge soon after? Would the lack of a dominant system lead to many more smaller chaotic systems? Do we just not know what would happen, so that it's concerning in that it's unknowable?

There is no requirement that water MUST circulate. It could simply stagnate. That's pretty much the worst case though, a weakened gulf stream is not the same as a total collapse.

Just watch The Day After Tomorrow to know what happens.

You can kiss Northern Europe as a habitable area goodbye. So yes, it matters quite a bit.

Earlier quoted context omitted.

Yeah - even where I am there has been a pull back on stuff. We've got a ban on plastic straws (ie, you can't use one then throw it in the trash in the resteraunt) to help save nature. But you go outside and the amount of trash just blowing into the water from various encampments near the water is just nuts. Their are claims of concerns about carbon emissions, but absolute opposition to any work around nuclear. If car…

Trash from encampments is negligible when you realize how many plastics are just dumped into the ocean

Not where I live. The trash from encampments is pulled up and down the shoreline (tons of bird and other life) with every tide. It's noticeable.

Tons of plastic in ocean for sure, but less noticeable unless you are in asia where the rivers and coastal areas are crushed with trash at times.

It's just weird our focus is on a plastic straw being disposed of in a restaurant. I mean, the amount of plastic bags in the shipping boxes I see on my street each trash day - mindboggling (airbags amazon and others use).

I sure hope Western Europe likes it cold. Paris is on roughly the same latitude of Quebec city.

Norway would probably be hugely affected. They are pretty far up north, but, thanks to Gulfstream, have rather mild weather on the coast.

Can't read the whole article, but how radically can the Gulf Stream really change? Isn't a current going in that general direction more or less mandated by the Coriolis effect? It's why I figured the west and east coasts of continents at similar latitudes (both in the Northern and Southern hemispheres) have similar climate patterns. (West coasts more temperate, east coasts more variable and humid).

Barcelona and Washington D.C. are on the same latitude, the weather difference is caused by the gulf stream pushing warm air north, I would imagine it could stop doing that.

Chicago is below Rome. My latitude puts me somewhere in Syria. Not sure what is worse the humidity where I live or Syrian Desert.

The actual title is "Observation-based early-warning signals for a collapse of the Atlantic Meridional Overturning Circulation."

I don't think the AMOC is exactly the same as the Gulf Stream, although I believe they are related. This is not my area of expertise.

Could anyone explain this a little better? Why was the title changed?
