“But modelling suggests ice volume in glaciers at this point in time wasn’t great enough to explain such a low sea level. So how can we explain this ‘missing’ ice?” Poor modeling?
Have these researchers considered sinking and rising land mass? For example areas of North America and Eurasia are still rising from loss of heavy glacier weight. This also affects the coastal areas as well and will continue to do so. So how does rhis change their ice volume calculations?
