Facing rising sea levels, Tuvaluans are migrating to Australia under a new climate-change visa program. Australia will grant 280 visas annually, a response to Tuvalu's vulnerability to flooding and saltwater intrusion. Over 3,000 Tuvaluans applied for the first batch of visas, with successful applicants expected to arrive in Australia by year's end. While Tuvalu implements coastal adaptation projects, the digital preservation of the nation is also underway as a safeguard against complete submersion.
