As COP30 begins in Brazil, bringing together global leaders to address the escalating climate crisis, this short article will focus on a critical and imminent climate tipping point: the potential breakdown of the Atlantic Meridional Overturning Circulation (AMOC) and its impacts on Caribbean fisheries and countries.
