Climate model simulations can be diagnosed to assess contributing causes of particular phenomena. Climate is not controllable system. The models are only available tools for forecasting plausible climates in years and decades ahead. The biosphere plays pivotal role in the climate system. Land ecosystems are a dynamic component of the global carbon and water cycle. More than one third of CO₂ in the atmosphere is exchange annually with the land biosphere. Land ecosystem processes also control exchange of energy and momentum between atmosphere and surface. We must better understand the global evolution land ecosystem as main agent in Earth Climate System dynamics. The model will help to assess impact of climate changes on natural vegetation patterns, surface characteristics and land carbon storage. For these aims Lund-Potsdam-Jena dynamic global vegetation model coupled with INM (RAS)/ICMMG (SB RAS) climate model is described and resulting prediction, under scenario A2, of global vegetation patterns are discussed in this paper.
