Q. According to a recent study published in Environmental Research Letters, which critical Atlantic ocean current is at risk of collapsing?
Answer: Atlantic Meridional Overturning Circulation (AMOC)
Notes: The Atlantic Meridional Overturning Circulation (AMOC), which includes the Gulf Stream, circulates warm water from the tropics northwards and cold water south; its collapse, as warned in recent studies, could disrupt global climate, impact rainfall and temperature patterns, and is weaker than at any point in 1,600 years.
