Atlantic Ocean current may collapse, claims study. What does this mean for climate, weather in US, Europe?

Catastrophic effects could be released all over the world if the AMOC collapses. The US, Europe, and other places may see abrupt and severe weather shifts. While coastal towns like Boston and New York might witness a rise in sea level, Europe might experience an ice age. The East Coast may need to prepare for hurricanes and harsher storms. Additionally, across the central and western United States, precipitation and snowfall may be severely reduced.

The AMOC is a vital conveyor belt of ocean water and air, influencing weather patterns. Warm, salty water moves northward from the tropics via the Gulf Stream along the U.S. East Coast to the North Atlantic, where it cools, sinks, and returns southward. This process maintains Europe's milder climate and brings colder waters to North America's coast.

Using advanced statistical tools and ocean temperature data spanning 150 years, researchers estimate a 95% certainty that the AMOC will halt sometime between 2025 and 2095. This prediction contrasts with the Intergovernmental Panel on Climate Change's (IPCC) view that an abrupt AMOC change is «unlikely» during this century.

The study's authors attribute the potential AMOC collapse to global warming, which accelerates the melting of Greenland ice. The influx of freshwater from melting ice weakens or disrupts the AMOC's normal sinking of salty water, possibly leading to its collapse. This process could trigger significant and far-reaching climate changes.

While some experts express reservations about the study's conclusions, others
