Risk of local biodiversity loss, estimated as the proportion of species in a given area projected to become endangered , and therefore at high risk of extinction, is projected to affect a greater number of regions experiencing increasing warming. About one-third of land area risks more than 50% of species becoming "endangered" by 4.0° GSAT warming . That is, the deep orange and red areas in Figure 2.6 are those areas for which >50% of species currently inhabiting those ecosystems are projected to lose >50% of their climatically suitable habitat. Species' losses are projected to be worst in northern South America, southern Africa, most of Australia and at northern high latitudes  .
