In 2025, may the Gulf Stream system truly fail?

Northwest Europe is seeing milder weather thanks to a cycle of marine currents that transport warm water from the Gulf of Mexico to the north of Britain. Thus, a systemic failure might cause the climate in this area to change drastically and drop temperatures.

Leading climate scientists, however, have significant qualms about the study's findings. According to these specialists, it's not a given that the Gulf Stream will change this century.

This system, also known as the Atlantic Meridian Recirculation Cycle (AMOC), would not collapse as quickly, according to the most recent research by the Intergovernmental Panel on Climate Change.

 Professor from the University of Copenhagen who was a member of the research team. Since we began monitoring this current in 2004, there has been worry about the Amoc's deterioration, according to Peter Ditlevsen. As Amoc travels toward the north pole, the hot water cools and settles to the bottom.

It might fall between 2025 and 2095.

However, because of climate change, the ice in the north is melting quickly, particularly in Greenland, which causes this current to cool further south before it can get that far north. Temperatures in Europe might decrease by much to 10-15 degrees if Amoc falls, while sea levels along the US east coast might rise. 

Rainfall patterns in agricultural regions that provide food for billions of people may also change. When the system started its present cycle again 12,000 years ago, Amoc was in its last collapse at the start of the Ice Age 115,000 years ago. According to the newly published study in Nature Communications, Amoc may collapse between 2025 and 2095.The analysis is predicated on the supposition that the rate of growth in greenhouse gas emissions will remain the same. If the rise in greenhouse gas emissions slows down or if emissions start to drop, Amoc's demise might not be so imminent. Scientists claim the results of this new study are "far from being accepted by the entire scientific community," according to Ben Booth of the UK Meteorological Service.

Professor at the National Marine Science Center at the University of Southampton Penny Holliday asserts that there is "no convincing evidence" that Amoc is waning.

"We are aware that Amoc may cease to function as it does now at some point, but it is incredibly difficult to take this for granted.

"I would point to heatwaves if my neighbor questioned whether he should be more concerned about heatwaves or the prospect of an Amoc crash. We can already see it, and we know it will only get worse.

The main reason why the most recent study is not widely regarded by scientists is that it assumes a lot of things about Amoc.

 However, due to the complexity of the climate system, experts claim they currently lack the knowledge necessary to completely comprehend Amoc.
