There is no consensus on the definition and status of climate refugees owing to the distinct meaning the term refugees carry under international laws. There are still gaps in understanding how climate change will work as the root cause of migration. Even if there is recognition of climate refugees, who is going 'to provide protection? More emphasis has been given to international migration due to climate change. But there is a need to recognize the migration of such people within the countries also so that their problems can be addressed properly.

While mitigating climate change is a critical global objective, the passage's primary inference is centered on the current lack of understanding, recognition, and protective mechanisms for climate migrants. It does not primarily advocate for stopping climate change as the main conclusion to be drawn from the given text.

The passage acknowledges climate change as a significant factor in forced migration. However, it does not claim that it will be the *most* important reason for migration in the future.
