The Intergovernmental Panel on Climate Change says that up to 30 percent of animals and plants face an increased risk of extinction if global temperatures rise 2 degrees Celsius (3.6 degrees Fahrenheit) in coming decades. But anthropologists also fear a wave of cultural extinction for dozens of small indigenous groups — the loss of their traditions, their arts, their languages.
“In some places, people will have to move to preserve their culture,” said Gonzalo Oviedo, a senior adviser on social policy at the International Union for Conservation of Nature in Gland, Switzerland. “But some of those that are small and marginal will assimilate and disappear.”
