Climate Crisis and the Future: The Day After Tomorrow's Warning

The Day After Tomorrow

I'm watching the flick The Day After Tomorrow after CNN mentioned it could be occurring now.
https://edition.cnn.com/2021/08/06/world/climate-gulf-stream-collapse-warning-study-intl/index.html

"A crucial system of currents in the Atlantic Ocean that helps control temperatures in the Northern Hemisphere and has implications for the entire planet's weather systems is showing signs of instability due to human-made climate change, scientists say.

Its collapse would have dire consequences for our weather and life on Earth."

In the movie, some kind of weather anomaly could make super cold air tunnel from upper atmosphere and freeze everything below. Can it happen if the currents were very unstable? Which of the movie scenes could become true?

Back to the CNN article:

"Global weather patterns are critically linked to the circulation and its transport of heat and nutrients around the planet. A collapse of this system would result in significant and abrupt changes, including fast sea level rise, more extreme winters in Western Europe and disruptions to monsoon systems in the tropics.

It could also have a cascading effect and destabilize other components of the Earth's climate system, including the Antarctic ice sheet and the Amazon rainforest.

This scenario was the premise for the 2004 climate science fiction film "The Day After Tomorrow," in which a series of extreme weather disasters strike after climate change caused the AMOC to collapse."

Which of the movie scenes could become true?

As I recall that movie, practically none.
The movie is a classic disaster-film, with a bit higher budget than usual so it's low-A instead of the classic mid-B class.

The scenario of the day after tomorrow is nonsense. Descending air will warm up because the air pressure increases and it compressed. Places where the air is descending tend to have sunny dry weather.

There does however seem some cooling going on in the north Atlantic. If you go to https://data.giss.nasa.gov/gistemp/maps/ and you get the (Jan-Dec) anomaly of 2000-2020 compared to 1950-1980 you can see that there is a colder patch south of Greenland. It's not really colder than 1950-1980 but it hasn't warmed as much as the rest of the Atlantic.
This does seem linked to a slowdon in the gulf stream

I really don't see anyone saying that the gulf stream is "suddenly collapsing". It will just get weaker slowly, so I don't expect any sudden changes.

A lot of people may not realize that this movie was based on a book written by none other than Art Bell, of Coast to Coast AM fame [the original UFO Central], and alleged repeat alien abductee Whitley Strieber - author of Communion.

Greenland's freshwater addition is sinking the saltwater Gulf Stream, making it return earlier ; or, at least that was the reason given for a hard UK winter back in the 2000's sometime.

Here’s the link to the paper in question:

From what I can recall, likely none. The weather conditions were treated in an absurd manner because that's what the script needed.

And by the way @Cobul it took only a matter of seconds on the Internet to get articles pointing out many of the absurdities of the "science" in the movie. You should learn to use Google.

Of course Whitley may have inside knowledge.

It also only took a matter of seconds to open the links in the OP, and the links in those links as well, and find the original peer-reviewed Nature Climate Change article that OP was referring to, which I then posted in post 6.
