A new oceanographic analysis from the University of Colorado in Boulder reveals a significant 30 percent decrease in salinity in a traditionally salty region of the Atlantic over the past six decades. Researchers attribute this shift to accelerated glacier melt, increased precipitation at high latitudes, and climate change-induced atmospheric circulation changes. This decline is bringing the Atlantic Meridional Overturning Circulation (AMOC), including the Gulf Stream, closer to a tipping point. Scientists warn that a collapse of the AMOC could lead to substantial cooling in Europe, potentially by up to ten degrees Celsius within decades, fundamentally altering climate patterns, agriculture, ecosystems, and weather extremes globally. Similar salinity decreases are also observed in the southern Indian Ocean.
