Content: That meant that sea level was around 70 meters higher than today - that is also how much the ice on Earth today (mostly situated on Greenland and Antarctica) could raise sea level, should it all melt. The Earth's history thus teaches us to expect large changes in sea level as we are warming up the climate with our emissions of greenhouse gases. But how much and how fast will sea level rise? To answer this question, scientists have come up with two fundamentally different approaches to model sea level rise. The first is physical models, which consider the different physical processes that cause sea levels to rise. The second is semi-empirical models, which attempt to exploit the information contained in measurements of past sea level changes. Physical Models
Physical models aim to describe quantitatively the different physical processes that contribute to sea level rise. Global sea level can be raised in three fundamentally different ways: (i) By altering the volume of the existing ocean water mass by warming, a process called ‘thermal expansion'. (ii) By adding water mass.
