Deep ocean control of global temperature after net-zero emissions
摘要
We analyse outputs from both climate mitigation scenarios and an energy balance model to investigate how deep ocean processes shape centennial-scale trajectories of global mean surface temperature after net-zero emissions are achieved. While surface temperature decreases as carbon dioxide concentration declines, this cooling trend could eventually reverse when vertical heat diffusion warms the deep ocean sufficiently to reduce the vertical temperature gradient, thereby weakening the deep ocean heat uptake.
