Short summary

Around 8200 years ago, Earth experienced an abrupt climate event when melting glaciers disrupted Atlantic Ocean circulation, triggering rapid global changes. Using statistical methods that account for dating uncertainties in paleoclimate records, we find tropical rainfall patterns shifted dramatically for 150 years. The regional complexity of these changes, verified by model simulations, provides insights for understanding how similar ocean changes could impact rainfall in our warming world.
