Sydney, Australia frequently floods during La Niña years. If a major current in the Atlantic Ocean shuts down, new research suggests this could become the norm.

A shutdown of a major current in the Atlantic Ocean would rapidly transform wind, temperature, and precipitation patterns across the whole globe, according to new research.

The current is already slowing, likely at least in part because of human-caused climate change. Now, scientists have found that, if the Atlantic Meridional Overturning Circulation (AMOC) collapses completely, there would be never-before-predicted impacts, according to astudypublished last week in the journal Nature Climate Change.
