Climate refugee: an increasingly used term

Is "climate refugee" a term we should use for those displaced by the impact of severe weather or geographical changes due to climare change? Dictionary.com has now included climate refugee as a term used to define "a person who has had to flee their home due to the negative effects of climate change." However, several people disagree that the term should be linked to "refugees" who have to flee their homes from persecution and are protected under the The United Nations 1951 Refugee Convention.

In a landmark decision, Australia annonced that it is offering residents of the Pacific Island of Tuvalu visas to escape the island from effects of climate change. The island nation has been experiencing rising sea levels and had requested Australia to develop a path for its citizens to leave the island yet ensure that there would not be a brain drain. (FT, Nov 12, 2023). Interestingly, the residents of Tuvalu have rejected the term "climate refugee".

I believe a nuanced understanding of the impact of climate change affecting migration patterns should be understood before using generalised terms such as "climate refugee."
