So this is an example of one of the issues we're going to have to reckon with in the coming years. The people of Tuvalu are rapidly losing their home and the islands will likely be gone within the next 10-15 years if sea levels continue to rise. It's a relatively small island and number of people, but it's still 11,000 people that will no longer have homes and essentially be stateless.
International law is currently ill-equipped to deal with this reality. There is nothing in any of the current refugee conventions that stipulate accommodations for climate refugees, which means that no country is under any obligation to accept these people when they're forced to flee their homes.
I'm aware the article is from May but Tuvalu has been bracing for this for several years now.
