Climate change is one of the greatest threats facing humanity today.The associated consequences, such as extreme weather events, sea level rise, water crisis, among others, will have a profound impact on economic growth, food insecurity, working conditions, lack of access to natural resources, among others.Although Chile is responsible for 0.25% of the global emissions responsible for global warming, it is classified as a country vulnerable to the impact of this phenomenon, since it meets seven of the nine conditions defined by the UN.The result of the interaction of the consequences of climate change, added to the complex social and power distribution structures (socioeconomic, political and cultural) of various societies, is likely to drive vulnerable groups to migrate.Unfortunately, these groups will often face this migratory process in conditions of socioeconomic precariousness and greater exposure to risks during border crossings.This situation of vulnerability can translate into worse results in physical, mental and social health and can even generate or deepen existing humanitarian crises in various border corridors.Although the need to address migration induced by climate change has been recognized in various international treaties since the 1990s, government decisions normally discuss with greater force aspects related to state sovereignty and security, ignoring the approach to social vulnerability that migrants face.Even less is the specific response that exists around mobilities generated by climatic reasons.Considering that the United Nations has estimated that climate-related disasters could double the number of people requiring humanitarian assistance to more than 200 million each year by 2050, the development of policies and practices that provide an effective response to displacement is urgent and a priority. from a perspective that includes addressing those social conditions that determine people's health.Mitigating, acting and adapting to this phenomenon is a task that brings us all together.*Researcher at the Faculty of Nursing of the U.
