The repeated isolation of the Atlantic Ocean during the Messinian led to at least the partial desiccation of the Mediterranean Sea and to the deposition of massive evaporites (Messinian Salinity Crisis). Overall, proxy data do not indicate dramatic climatic changes in the Mediterranean region for the time of the Messinian Salinity Crisis but a cons...

The Late Miocene belongs to the late phase of the Cenozoic. Climate at that time was still warmer and more humid as compared to today, especially in the high latitudes. Corresponding to the climate situation, palaeobotanical evidences support that vegetation in the high northern latitudes changed significantly from the Late Miocene until today. To...

During the Cenozoic, global climate got successively colder. The Late Miocene belongs to the late phase of the Cenozoic cooling. The climate at that time was still warmer and more humid as compared to today. Especially, high latitudes were warmer. Corresponding to the climate situation, palaeobotanical evidences support that vegetation in the high...

A coupled atmosphere-ocean model is used to examine the climatic effects of Southeast Asian deforestation. On the deforested grid cells surface temperatures rise, and precipitation is reduced after deforestation. Regional moisture convergence and convection increase and lead to strongly enhanced rainfall. The easterlies and associated oceanic surfa...

We assess the land surface model JSBACHv4, which was recently developed at the Max Planck Institute for Meteteorology as part of the effort to build the new Earth System model ICON-ESM. We assess JSBACHv4 in simulations coupled with ICON-A, the atmosphere model of ICON-ESM, hosting JSBACHv4 as land component to provide the surface bounddary conditi...

This work documents the ICON‐Earth System Model (ICON‐ESM V1.0), the first coupled model based on the ICON (ICOsahedral Non‐hydrostatic) framework with its unstructured, icosahedral grid concept. The ICON‐A atmosphere uses a nonhydrostatic dynamical core and the ocean model ICON‐O builds on the same ICON infrastructure, but applies the Boussinesq a...

ICON-A is the new icosahedral non-hydrostatic (ICON) atmospheric general circulation model in a configuration using the Max Planck Institute (MPI) physics package, which originates from the ECHAM6 general circulation model, and has been adapted to account for the changed dynamical core framework. The coupling scheme between dynamics and physics emp...

Based on the MPI-ESM simulations for the Coupled Model Intercomparison Project Phase 5 (CMIP5) and on simulations with the submodel Cbalone we disentangle the influence of natural and anthropogenic vegetation changes on land carbon emissions for the years 1850 till 2300. According to our simulations, climate induced changes in distribution and prod...

[1] The present paper addresses the origin of natural variability arising internally from the climate system of the global carbon cycle at centennial time scales. The investigation is based on the Max Planck Institute for Meteorology, Coupled Model Intercomparison Project Phase 5 (MPI-MCMIP5) preindustrial control simulations with the MPI Earth Sys...
