Species are the fundamental unit of ecosystems, and the increasing risk of local losses of species increases the risks of reduced ecosystem integrity, functioning and resilience with increasing warming . As species become rare, their role in the functioning of the ecosystem diminishes . Loss of species locally reduces the ability of an ecosystem to provide services and lowers its resilience to climate change . At 1.58°C GSAT warming, >10% of species are projected to become endangered , and at 2.07°C this rises to >20% of species, representing a high and very high risk of biodiversity loss, respectively  . Biodiversity loss is projected for more regions with increasing warming, and will be worst in northern South America, southern Africa, most of Australia and at northern high latitudes  .
