The Gulf Stream, a warm marine current that flows from the southern tip of Florida to Europe via the US eastern seaboard, could be on the point of collapsing due to melting ice from the Poles, leading to a new Ice Age. A group of 44 leading climatologists signed an open letter warning that the Atlantic Meridional Overturning Circulation (AMOC) could break down as early as next year, meaning the Gulf Stream would cease operating. Without the warmth the Gulf Stream brings from the tropics, Britain and much of Europe face a freeze on a scale unprecedented since the last major Ice Age. The dire possible impacts of a Gulf Stream collapse in 2025 are explored, including freezing temperatures, travel chaos, fuel and food shortages, disease outbreaks, and social unrest.
