The scope of this research is to analyze the growing migratory flows in Latin America and the Caribbean related to climate change. The aim is to identify new trends in cross-border forced displacement on the American continent and examine the protective regulatory framework available in the region to protect new displaced people in the climate crisis scenario, especially given the absence of a specific international protection standard, which implies confronting the current International Refugee Law, in addition to other regulations such as the 1998 Guiding Principles Relating to Internally Displaced Persons and documents related to protection in the area of migration, with regard to the current demands and hypotheses of forced mobilizations and migrations caused by catastrophes and extreme weather phenomena. The objective is, finally, to verify the capabilities and potential of the Inter-American Human Rights System (IAHRS) for the adequate protection of people forced to be displaced for climate and environmental reasons. Above all, the possibility of effective application of human rights standards and protective standards developed, both in environmental issues and human mobility issues, at the regional level is considered as a response to anomie. Special attention is given to the interpretation work undertaken by the Inter-American Court of Human Rights (IDH Court) and its contributions that are in line with and promote the humanization of International Law, as supported by Antônio Augusto Cançado Trindade.
