Scientists say there’s just too little data available to suggest the Gulf Stream is slowing down, and there won’t be in the next five years. 
Die kalte Sonne looked at the Atlantic Meridional Overturning Circulation, the system of surface and deep currents in the Atlantic Ocean that – among other things – transports warmer tropical water to the north Atlantic and to Europe, thus keeping the old continent a few degrees milder in the wintertime.
Some alarmist scientists, like at the Potsdam Institute, have been suggesting that climate change would cause this massive heat conveyor to stall and to cast the North Atlantic into a deep freeze, like in the film “The Day After Tomorrow”.
But Die kalte Sonne here reports that there’s no consensus or scientific data to support this media popular scenario.
“Low confidence”
For example, Chapter 9 of Working Group I of the 6th IPCC report there’s “low confidence” in AMOC changes over the 20th century and only medium confidence of an abrupt collapse over the 21st century (model-based).

This means scientists have nowhere near enough information about how the AMOC has changed over the past century, or will change up to the year 2100. They have no clue.
Thus a climate-tipping AMOC stall remains adventurous speculation.
“Nobody knows”…”too little data”
German oceanographer Martin Visbeck also warned in a September 2, 2021, interview with Die Zeit that there’s too little data available to allow any reliable conclusions to be drawn.
When Visbeck was asked by Die Zeit what he thought about the 20 years of data gathered so far by a huge network of ocean buoys, he told Die Zeit:
Not much. One could possibly detect a slight downward trend using the mean of the data. But nobody knows whether this has to do with the usual data fluctuations, or if there’s a real long-term reduction in the current behind it. Personally I wouldn’t trust any trend that is based on so little data. It all could change in five years. And in my view, even then there will be no reliable evidence that would allow a statement on whether the AMOC has weakened or strengthened over the past 100 years.”
