"A potential collapse of this ocean current system would have severe consequences around the globe, authors of the new study said." By Doyle Rice via USA TODAY Headline Iage Credit: NASA/Goddard Space Flight Center A large system of ocean currents in the Atlantic – which includes the Gulf Stream – has been disrupted due to human-caused climate change, scientists reported in a new study published Thursday. If that system collapses, it would lead to dramatic changes in worldwide weather patterns. The Atlantic Meridional Overturning Circulation, or AMOC, transports warm, salty water from the tropics northward at the ocean surface and cold water southward at the ocean bottom. "The Atlantic Meridional Overturning really is one of our planet's key circulation systems," said the author of the study, Niklas Boers from the Potsdam Institute for Climate Impact Research in Germany. Findings from a similar 2018 study drew comparisons to the scientifically inaccurate 2004 disaster movie "The Day
