The Atlantic meridional overturning circulation (AMOC) is a system of currents in the Atlantic Ocean, characterized by a northward flow of warm, salty water in the upper layers of the Atlantic, including the Gulf Stream, and a southward flow of colder, deep waters that are part of the Thermohaline circulation. The AMOC is an important component of the Earth’s climate system.
Some autists are claiming that current climate models do not accurately model AMOC. They argue that large scale injections of freshwater (for instance, melting of greenland's ice sheets) may force a corrupt collapse of AMOC.
Are they right? What are the implications if AMOC collapses?

An understandable response. Obviously climate modeling would seem like black magic to someone that struggled in their college algebra course

In my train of thought, Greenland melting wouldn't do much. Greenland melting in a year, would be like trying to stop the Jetstream with all our nukes. You might stop it for a while, but the thermocline forces (sun heating at the equator, cooler water at the poles) that created the AMOC initially would restart it eventually, salt levels be damned.
As for what happens if/when it shuts down, we'll the north gets cold, the Caribbean gets hot.

>Are they right? They have seventeen thousand different models to ensure that, texas sharpshooter style, they will always be right. So yes, they are right.
>what are the implications Europe is going to fucking freeze dude. Global warming is gonna get so hot that europe is going to freeze, don't you listen to the climate scientists. 99% of them agree on this.

There's a reason it's called "climate change" you fucking sperg. Because while the global average temperature will rise, there will be local exceptions and variations.

i thought the AMOC disruption was decided to be not a huge threat like ten years ago?

There is some evidence that climate models may be overestimating AMOC stability by wrong small-scale mixing parameterization and an incorrect Atlantic salt budget see >advances.sciencemag.org/content/3/1/e1601666
There is plenty of evidence of AMOC collapse in the paleoclimate archives. The most salient examples are the Dansgaard-Oeschger events and the Younger Dryas climate events, which were all associated with an interhemispheric "seesawing" of warming. However, those examples come from a much colder glacial climate state, so they may not directly translate into the modern world.
Are there examples of AMOC collapse in a warmer world? The most immediate paleo-analogue may be the last interglacial ("Eemian") 120,000 years ago, which was marginally warmer than modern times. Far-field sea level reconstructions suggest a very rapid sea level rise late in the Eemian towards a highstand of +9 meters above the present sea level. See >nature.com/articles/ngeo1890
This is internally consistent with an orbitally induced collapse of ice sheets, an ensuing freshwater forcing and subsequent collapse of overturning in the ocean.

Same implications for every other mass climate shift in the last eon, lots will die and some will survive and evolution will run its course

Hey guys. Remember that recordbreaking cold winter in the US northeast? Ye, the NOAA doesnt remember it.

Yeah, kill the messenger because that actual data shows what crap the NOAA is spewing out.
