20. Exhibit 6-10: Major ecoregions in Canada today and the distribution that would be in equilibrium with one business-as-usual projection of climate in 2050.

21. Exhibit 6-11: Biosphere model projections of fate of the Amazon rainforest by under the A2 GHG emission scenario. Shown is the extent of agreement using the changes in climate simulated by 15 different AOGCMs as input to a the LPJ dynamic vegetation model.

22. Exhibit 6-12: Left, distribution of grid cells with different amounts of forest cover in 2050 as simulated by the Hadley Centre AOGCM coupled to the LPJ DGVM for the A2 emission scenario. Right: Fractional forest cover in grid cells if the climate is held at its state in 2050 and the rainforest is allowed to eventually fully respond to the change in climate.
