Abstract: Abstract Climate change is likely to negatively affect the habitats of non-human primate species. Recent research has identified a near-linear relationship between cumulative CO2 emissions, and the resulting regional and seasonal temperature increase. Here, we use this relationship to assess the potential impact that cumulative CO2 emissions could have on the ranges available to primate species. We used data from the International Union for Conservation of Nature on ranges for 426 species and subspecies of non-human primates, combined with spatial climate data from the Coupled Model Intercomparison Project Phase 5 that represent regional and seasonal temperature changes per unit CO2 emissions. Using these data, we estimated the portion of the area of each species’ range where annual average temperatures exceed the Pre-industrial Seasonal Maximum Temperatures (PSMT), for cumulative CO2 emissions from 600 to 2000 billion tonnes of carbon. For the level of emissions corresponding to a 2 °C global temperature increase scenario, 26.1% of all ranges had temperatures in excess of their PSMTs, and for 8% of species, the entire current range was above their PSMT. This suggests the potential for considerable loss of or compromised habitat for non-human primates on a global scale, as a result of the emergence of climate conditions that are outside of the scope of historical experience for many species. Our results point to key priorities for conservation efforts, as well as the need for future research on strategies to increase the resilience of vulnerable local non-human primate populations.
