Assessment of Siberian Permafrost in the Climate Change Regime

The impact of permafrost zones on the global climate is estimated using a global climate model that parameterizes the interactive fluctuations of climate and greenhouse gases {GHGs). This study develops a new coupled model of CO2 and CH4 global cycles (CMCCGC) for the parameterization of environmental processes in the Siberian permafrost zone based on remote sensing data, allowing us to describe in detail a structure of radio-heat fields in the tundra and adjoin permafrost zones. The results of this study show that a reliable understanding of the role of Siberian permafrost in global climate change requires addressing many specific tasks.
