| One of the major phases of sea level rise during the last deglaciation (~19‐11 thousand years before present (ka BP)) is Meltwater Pulse‐1A (MWP‐1A, ~14.5 ka BP), when sea levels rose by 8.6 to 18 meters in less than 400 years. Whether the meltwater originated from the partial disintegration of northern hemispheric (NH) ice sheets, from Antarctica, or both, remains controversial. Here we perform a series of idealized transient simulations of the last deglaciation, focusing on MWP‐1A, with a three‐dimensional oxygen‐isotope enabled Earth System Climate Model. Three meltwater scenarios are considered during MWP‐1A: a sole northern hemispheric source discharging into the North Atlantic, a sole Antarctic source and a combined NH‐Antarctic source. A comparison... |
