Conflicts on the stability of the Atlantic Meridial Overn, Circulation (AMOC) have been resumed, recently a study indicates that the current system has not weakened since the 1960s. AMOC, which includes the Gulf Stream, plays an important role in regulating the global climate by transporting heat from tropics to the northern hemisphere. Any recession can result in severe climate disruption, including extreme weather patterns and cold temperatures in parts of Europe. While the study suggests that the system remains stable, conflicting research and expert opinion indicates that uncertainty remains.
Conclusion from recent studies
according to a Study Published in Nature Communications, AMOC strength remains stable in the last six decades. Researchers used the updated climate model, which is a factor in greenhouse gas concentrations, usually reusing indicators such as sea surface temperature. The study suggests that the heat flow of sea air, which measures the heat exchange between the sea and the atmosphere, is a more reliable metric. Conclusions do not suggest no significant decrease in heat transfer, the suggestion of AMOC has not weakened yet.
Nicholas Fukal, Woods Hole Oceanographic Institution Assistant Scientist and Co-writer, Stated In a press release that the anticipated changes in AMOC have not yet taken place, it does not deny the future recession.
Experts raise concerns over functioning
Many scientists have questioned the reliability of the functioning of the study. Maya Ben-Yami, a climate researcher at the Technical University of Munich, told Different climate indicators used to assess AMOC trends in an email can produce different results, which makes it difficult to conclude firm.
Stephen Rahmstorf, professor at Oceanography at the Potsdam Institute for Climate Impact Research, told Live Science that uncertainty in heat transfer measurements could be wrongly estimated. He argued that other models used in previous research, which indicate that AMOC has already weakened, may be more reliable.
Future recession is certain
Despite disagreement over the current situation of Amoc, researchers widely agree that its weakening is inevitable. David Thornley, Professor of Climate and Ocean Science at University College London, told Live Science that previous studies show that AMOC started weakening in the 1800s and has been relatively stable in recent decades. The possibility of future disruption remains a major concern, with scientists emphasized that with significant cuts in greenhouse gas emissions, the AMOC would slow down in the coming years.
