The article is an attempt to respond to the need to find international legal solutions, extremely important for people living in the countries threatened by the consequences of climate change, among others, the effects of rising sea levels in the seas and oceans. I try to direct attention to the still underestimated in the international law problem of the so-called "climate refugees". Behind the concept that defies the classic definitions of "refugees", there are hundreds of thousands today, and soon perhaps millions of people whose lives, health and property will be threatened by the forces of nature. The originality of the approach presented in the article is an attempt to consider whether appropriate legal solutions that protect vulnerable populations can be sought on the basis of international humanitarian law, since so far no other branch of international law seemed adequate to take up this challenge. The urgent and important dimension of the problems discussed in the article completes the necessity of searching for and finding answers to questions about the relationship between climate change and public international law. These are the legal consequences of climate deterritorialisation of sovereign states, such as the status of the population of the state without land territory, the loss of territories by archipelago states, the change of the sea borders, territorial waters, exclusive economic zones, and finally the responsibility of states for climate change. In the context of 'climate refugees', there is still no binding legal act that would meet the needs of thousands of people affected by climate change. This causes dissonance because, beyond any doubt, the situation in which these people find themselves raises a lot of fears - for their own lives, safety, health, etc. Today, entire communities and even countries face the problem of progressing deterritorialisation in face of climate threats. climate change, they face the risk of a non-culpable threat to their sovereignty.
