'We’ve fallen off a cliff': Scientists warn Atlantic currents could collapse as early as 2025
"It is very plausible that we've fallen off a cliff already and don't know it," said one researcher.
The system of Atlantic Ocean currents that drive warm water from the tropics toward Europe is at risk of collapsing in the coming decades, an analysis of 150 years of temperature data published Tuesday concluded.
"The Atlantic Meridional Overturning Circulation (AMOC), which includes the Gulf Stream, is a major tipping element in the climate system and a future collapse would have severe impacts on the climate in the North Atlantic region," states the study, which was published in the scientific journal Nature Communications.
Although the analysis notes that "assessments by the Intergovernmental Panel on Climate Change (IPCC), based on the Climate Model Intercomparison Project (CMIP) model simulations suggest that a full collapse is unlikely within the 21st century," the study's authors "estimate a collapse of the AMOC to occur around mid-century under the current scenario of future emissions."
"We show that a transition of the AMOC is most likely to occur around 2025-2095," the paper states with "95% confidence."
