Climatic risks interact with economic, political and social drivers to create risks to human mobility both directly  and indirectly . Extreme weather events are leading causes of forced displacement . Projected increases in the frequency and severity of extreme events  in combination with future population growth in hazard-prone regions  suggest that risks to mobility will increase in response to future global warming . For example, moving from RCP2.6 to RCP8.5  is projected to increase internal migration by 2050 from 51  million to 118  million people across South Asia, Latin America and Africa , although those estimates principally comprise migrants, whose decisions are also informed by non-climatic drivers, rather than involuntarily displaced people. Global levels of flood displacement are estimated to increase by 50% with each 1ºC warming . Should future warming reduce adaptation options for vulnerable populations , a consequence may be higher levels of involuntary migration and immobility . There is little evidence that climate- driven mobility negatively affects peace .
