Sudden changes in North Atlantic circulation during the last deglaciation

Abstract

Sudden changes in the flow of warm Atlantic surface waters into the Norwegian Sea occurred frequently during the last deglaciation, typically involving shifts in sea surface temperature of 5 °C in fewer than 40 years. These led to equally large and rapid changes in atmospheric temperatures, and to shifts in Atlantic deep thermo-haline circulation and ice-sheet melting rates.
