Biome shifts detected and attributed to climate change: a) observed linear temperature trend 1901–2002; b) potential vegetation under observed 1961–1990 climate; c) potential vegetation under projected 2071–2100 climate; d) vulnerability of ecosystems to biome shifts based on historical climate and projected vegetation.
