Land Ecosystem Changes under Global Warming

Caption: This image shows simulated ecosystem change by 2100, depending on the degree of global temperature increase: 2 degrees Celsius (upper image) or five degrees Celsius (lower image) above preindustrial levels. The parameter Γ (Gamma) measures how far apart a future ecosystem under climate change would be from the present state. Blue colours (lower Γ) depict areas of moderate change, yellow to red areas (higher Γ) show major change. The maps show the median value of the Γ parameter across all climate models, meaning at least half of the models agree on major change in the yellow to red areas, and at least half of the models are below the threshold for major change in the blue areas.
