Nearly one-third of the population of Tuvalu, a small Pacific island nation threatened by rising sea levels, have applied for Australia's landmark climate visa program. Official figures indicate that over 3,000 Tuvaluans, representing about one-third of the country's approximately 10,000 residents, have sought this visa, which offers a pathway to permanent residency in Australia. The climate visa, introduced by the Australian government in 2024, grants up to 280 permanent visas annually to Tuvaluans facing displacement due to climate change. Scientists warn that Tuvalu, composed of nine coral atolls with an average elevation of just two meters above sea level, could become uninhabitable within the next 80 years as sea levels rise at about 3.9 millimeters per year. The country's UN ambassador has described the high number of applicants as startling, highlighting concerns over a potential mass exodus. Tuvalu is seeking assurances from the United States that its citizens will not be barred from entry amid these migration efforts. While the Australian visa program offers a lifeline, experts note that millions more climate migrants worldwide may require refuge by 2050 due to similar environmental threats.
