In fact, in 1989, the UN designated Tuvalu as one of the many island groups most likely to be submerged in the 21st century due to global warming. Not to mention, the Alliance of Small Island States (AOSIS), of which Tuvalu is a member, brought climate change loss and damage, now a key area of ​​climate policy, to world leaders in the early of the 1990s.

AOSIS, an intergovernmental organization made up of 39 low-lying coastal and small island developing countries, was formed in 1990 in advance of the Second World Climate Conference to address climate change.
