Since biome location is determined by temperature and precipitation patterns, climatic changes pose a threat to the continued existence of biomes in their present locations. It would not take great changes in climate to make it impossible for a given biome to continue to exist in its current location. Beset by such climatic changes, a biome would seemingly face one of two fates: cease to exist or migrate following the changing climatic conditions. a. What circumstances would allow the biome to successfully migrate? b. What circumstances would simply destroy the biome and its biological diversity?
