Vegetation distribution under present climate conditions and equilibrium vegetation distribution under future climate conditions (scenarios) over Northern Eurasia in current climate and by the year 2090 as calculated by the RuBCliM ecosystem model (developed by modifying the SibCliM ecosystem models, Tchebakova et al. 2009, 2010, 2016) using an ensemble of Canadian (CGCM3.1), UK (HadCM3), and French (IPCLCM4) GCM outputs for the B1 and A2 scenarios for the IPCC Fourth Assessment Report (Core Writing Team 2007), where greenhouse gases induced global warming of 3–5 °C and 6–8 °C, respectively, by 2090 (Tchebakova et al. 2016)
