The northeastern American coast HA recently experienced increased flooding events.
A study connects floods into a delay of a large Atlantic current.
Up to 50% of the flood events from 2005 to 2022 was driven by a weaker amoc.
The northeast coast of the US has witnessed more flooding events in recent years due to the delay of a large stream in the Atlantic Ocean that increases the sea level, a new study has shown. The Atlantic meridional destructive circulation (amoc) influences the climate, weather and sea level around the planet by transporting heat, salt and fresh water through the ocean, but scientists are worried that it is weakened.
The study published last week in the American Association for the Advancement of Science Data from tidal meters used (an instrument that is used to follow sea level change) and complex ocean models to calculate how the Amoc has influenced floods in the region.
“The American Northeast Coast (USNEC) has been identified as a hotspot for accelerated sea level rise on the North Atlantic Ocean (NA) in the most recent decades,” the study emphasized.
The findings showed that between 2005 and 2022 to 50 percent of the flood events along the northeastern coast were driven by a weaker amoc.
With the climate, it is constantly changing and the atmosphere warms up, scientists fear that fresh water of melting pole -ice caps can considerably disrupt or collapse the amoc, which leads to devastating consequences.
“If the Amoc collapsed, this would dramatically increase the flood frequency along the American coast, even in the absence of strong storms,” Lipped at the Geophysical Fluid Dynamics Laboratory of the US National and Atmospheric Administration (Noaa) told in New Jersey New scientist.
“Even partial weakening [of the current] Can already have substantial consequences. “

This is not the first instance when scientists have warned about the collapse of Amoc. A study published last year claimed that the approaching disaster, accelerated by man -caused climate change, could take place in the late 2030s.
While the new study paints a picture of gloom, there is a silver lining. Because natural cycles in the strength of the amoc are largely predictable, scientists can predict which years many floods will see, up to three in advance.
This foresighting gaze can help authorities make decisions about emergency palatity and related infrastructure on time.
