While in the 20th century land use change was the largest driver of great ape extinction, by 2070 climate change is predicted to become the largest driver of extinction in great ape populations, due to existing habitat fragmentation, and poor thermoregulation limiting dispersal abilities \cite{Junker_2012}. Under current emissions, Carvlho et al. predict a 94 percent loss of great ape habitat in Africa by 2050. Even under RCP 2.6, a 85% decrease in great ape range sizes is predicted in just 3 decades time.
