在使用马克斯·普朗克气象研究所地球系统模型的两个敏感性实验中，全世界无冰陆地表面的植被覆盖被设定为森林或草地，以便量化大气和海洋成分对极端陆地表面边界条件的准平衡反应。经过400年的模式整合，全球年平均表面温度上升了0.7度K和下降了0.6度K，分别在森林和草地模拟，与控制模拟。此后，植被的地理分布被允许对气候作出相互作用的反应。在随后的500年的气候-植被动态相互作用之后，森林和草地模拟都收敛到与控制模拟基本相同的气候状态。这种趋同表明，在当前版本的MPI-ESM中没有多个气候-森林状态。引文：Brovkin，V.，T.拉达茨角H.

In two sensitivity experiments using the Earth System Model of the Max Planck Institute for Meteorology (MPIESM), the vegetation cover of the ice-free land surface has been set worldwide to either forest or grassland in order to quantify the quasi-equilibrium response of the atmosphere and ocean components to extreme land surface boundary conditions. After 400 years of model integration, the global mean annual surface temperature increased by 0.7 degrees K and declined by 0.6 degrees K in the forest and grassland simulations, respectively, as compared to the control simulation. Thereafter, the geographic distribution of vegetation has been allowed to respond interactively to climate. After subsequent 500 years of interactive climate-vegetation dynamics, both forest and grassland simulations converged to essentially the same climate state as in the control simulation. This convergence suggests an absence of multiple climate-forest states in the current version of the MPI-ESM. Citation: Brovkin, V., T. Raddatz, C. H. Reick, M. Claussen, and V.
