An analysis of the surface albedo variability between the climate models over Greenland offers insights into the drivers of inter-model differences. We show that mPWP ice sheet reconstructions are highly dependent upon the forcing climatology used, with Greenland reconstructions ranging from an ice-free state to a near-modern ice sheet.

Here we use the climatological fields derived from the results of the 15 PlioMIP climate models to force an offline ice sheet model.
The Pliocene Model Intercomparison Project (PlioMIP) has brought together nine international modelling groups to simulate the warm climate of the Pliocene. Therefore, it is essential that the model dependency of these results is assessed. Thus, the mPWP provides a natural laboratory in which to investigate the long-term response of the Earth's ice sheets and sea level in a warmer-than-present-day world.Īt present, our understanding of the Greenland ice sheet during the mPWP is generally based upon predictions using single climate and ice sheet models. Sea level was also higher than today, implying a significant reduction in the extent of the ice sheets. During an interval of the Late Pliocene, referred to here as the mid-Pliocene Warm Period (mPWP 3.264 to 3.025 million years ago), global mean temperature was similar to that predicted for the end of this century, and atmospheric carbon dioxide concentrations were higher than pre-industrial levels. 15 Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing, ChinaĬorrespondence: A.
