Climate-induced migration is not necessarily higher among poorer households whose mobility is more likely to be limited due to the poverty trap   . For example, in Bangladesh, vulnerability of rural populations is increasing, so many of the poorest employ migration as a strategy of last resort  that occurs as soil salinity  increases and is paralleled by economic diversification  . There is robust evidence and high agreement that rapid-onset climatic events trigger involuntary migration and short-term, short-distance mobilities . There is also robust evidence and high agreement that slow-onset climatic events  lead to long-distance internal displacement, more so than local or international migration , while sea level rise is expected to lead to the displacement of communities along coastal zones, such as in Florida in the USA .
