MegaRun: Simulation and Understanding of Glacial Cycles
Speaker: Andrey Ganopolski
Team members: Eva Bauer, Reinhard Calov, Matthias Hofmann, Victor Brovkin (guest)
Understanding the mechanisms of glacial climate change represents a major scientific challenge. In spite of considerable progress in empirical palaeoclimatology achieved in recent decades, the nature of glacial climate variability remains debatable and no generally accepted theory of glacial cycles exists. The aim of MegaRun is to gain considerable progress in understanding past climate changes by using an Earth system model of intermediate complexity in conjunction with data analysis.
The major goal of the MegaRun project is to perform simulations of the temporal dynamics of climate and ice sheets during the whole Quaternary period (ca. last 2 million years) using orbital forcing as the only externally prescribed forcing. Changes in the atmospheric concentration of major greenhouse gases and dust loading and deposition will be interactively simulated by the new version of CLIMBER-2-ICE model which is currently under development.
Specific research topics
- Development of the CLIMBER-2-ICE model version
- Study of glacial climate/carbon cycle variability at different time scales
- Preparation and performing of MegaRun
