The problem of greenhouse effect due to anthropogenic influence on the global cycles of greenhouse gases is under discussion in the scientific literature. This paper aims to contribute to solving this problem by proposing a new model of the coupled biogeochemical cycles of carbon and methane considering the spatial structure of their sources and sinks on a global scale. All reservoirs and fluxes of the carbon and methane that are taken into consideration in the proposed model have different temporal scales, while the spatial scale for sources and sinks of carbon and methane on the land is considered as 4 by latitude and 5 by longitude. World Ocean is parameterized by two-point models with four levels in depth with a separation between pelagic and upwelling zones. In addition, the interaction between the atmosphere and carbon reservoirs on the land and in the ocean includes the processes of photosynthesis, decomposition, respiration and burning. The global cycle of methane in the atmosphere-hydrosphere-land system is described by the scheme that takes into account the potential of the radiation fluxes, which is a function of time. Furthermore, the structure of the proposed model for the coupling of the carbon and methane cycles consists of 12 blocks, which carry out basic calculation procedures for their fluxes. Finally, results of the simulation experiments are discussed considering scenarios for changes in forest areas, showing their significant role in climate change issue.
