Abstract

Freshwater hosing has long been used in climate models to represent the perturbation associated with the release of icebergs during Heinrich Events. However, freshwater hosing ignores some of the icebergs-induced feedbacks on climate. It therefore bears the question whether the perturbed climate obtained through classical freshwater hosing experiments is realistic enough to be used as a proxy for a Heinrich Event. Using the fully coupled, water isotope enabled, climate model iLOVECLIM, we conducted a series of freshwater hosing experiments, accounting for the depleted signature of ice-sheet sourced water, under LGM conditions. Using paleoceanographic data, we integrated simulated and measured δ
