This article lists several areas, regions, and municipalities that have either been completely or markedly depopulated, or are involved in plans for depopulation or relocation due to anthropogenic climate change. Several factors created or worsened by climate change can be responsible for necessitating managed retreat or the relocation of people and/or infrastructure. These include rising sea levels, increased flooding risk, changes to the makeup of the land (e.g. a habitable area becoming a wetland), coastal erosion, increased susceptibility to dangerous cyclones, droughts, water shortages, wildfires, and other factors, all of which can overlap with each other to enhance the risk of danger or inhabitability of a formerly populated region.
The lists contain a general number of the number of people moved or at risk of being moved due to climate change-related causes, as well as rough dates for when programs to relocate were first created or for when a climate disaster first caused significant forcible displacement of a population.

Tuvalu is an island country in the Polynesian subregion of Oceania in the Pacific Ocean, about midway between Hawaii and Australia. It lies east-northeast of the Santa Cruz Islands, northeast of Vanuatu, southeast of Nauru, south of Kiribati, west of Tokelau, northwest of Samoa and Wallis and Futuna, and north of Fiji.
The Western Pacific nation of Tuvalu, formerly known as the Ellice Islands, is situated 4,000 kilometers (2,500 mi) northeast of Australia and is approximately halfway between Hawaii and Australia. It lies east-northeast of the Santa Cruz Islands, southeast of Nauru, south of Kiribati, west of Tokelau, northwest of Samoa and Wallis and Futuna and north of Fiji. It is a very small island country of 26.26 km2 (10.14 sq mi). Due to the spread out islands it has the 38th largest Exclusive Economic Zone of 749,790 km2 (289,500 sq mi). In terms of size, it is the second-smallest country in Oceania.
Demographic features of the population of Tuvalu include the age structure, ethnicity, education level, life expectancy, religious affiliations and other aspects of the population.
Tuvalu is a Polynesian island nation located in the Pacific Ocean, midway between Hawaii and Australia, with a population of 11,192 per the 2017 census. The economy of Tuvalu is constrained by its remoteness and lack of economies of scale. Government revenues largely come from fishing licences ; direct grants from international donors ; and income from the Tuvalu Trust Fund. The lease of its highly fortuitous .tv Top Level Domain (TLD) also contributes revenue. The sale of stamps since the independence of Tuvalu in 1976 has been an important source of revenue for the country and government. However, such revenue has significantly declined in recent years. Tuvalu has hardly any tourism. It has no tour guides, tour operators, or organised activities, and no cruise ships visit.
Kivalina(kiv-uh-LEE-nuh) is a city and village in Northwest Arctic Borough, Alaska, United States. The population was 377 at the 2000 census and 374 as of the 2010 census.
Managed retreat involves the purposeful, coordinated movement of people and buildings away from risks. This may involve the movement of a person, infrastructure, or community. It can occur in response to a variety of hazards such as flood, wildfire, or drought. Politicians, insurers, and residents are increasingly paying attention to managed retreat from low-lying coastal areas because of the threat of sea level rise due to climate change. Trends in climate change predict substantial sea level rises worldwide, causing damage to human infrastructure through coastal erosion and putting communities at risk of severe coastal flooding.
Kioa is an island in Fiji, an outlier to Vanua Levu, one of Fiji's two main islands. Situated opposite Buca Bay, Kioa was purchased by settlers from Vaitupu atoll in Tuvalu, who came between 1947 and 1962.
Kivalina v. ExxonMobil Corp., No. 4:08-cv-01138, was a lawsuit filed on February 26, 2008, in a United States district court. The suit, based on the common law theory of nuisance, claims monetary damages from the energy industry for the destruction of Kivalina, Alaska by flooding caused by climate change. The damage estimates made by the U.S. Army Corps of Engineers and the Government Accountability Office are placed between $95 million and $400 million. This lawsuit is an example of greenhouse gas emission liability.
Climate change has led to the United States warming by 2.6 °F since 1970. The climate of the United States is shifting in ways that are widespread and varied between regions. From 2010 to 2019, the United States experienced its hottest decade on record. Extreme weather events, invasive species, floods and droughts are increasing. Climate change's impacts on tropical cyclones and sea level rise also affect regions of the country.
Funafuti is an atoll, comprising numerous islets, that serves as the capital of Tuvalu. As of the 2017 census, it has a population of 6,320 people. More people live in Funafuti than the rest of Tuvalu combined, with it containing approximately 60% of the nation's population. The main islet, Fongafale, hosts Vaiaku, the administrative center of the nation.
Kausea Natano is a politician who served as the Prime Minister of Tuvalu from 19 September 2019 to 26 February 2024. He represented Funafuti as a Member of Parliament. He was first elected in the 2002 Tuvaluan general election and served as an MP until he was unseated in the 2024 Tuvaluan general election.
Between 1901 and 2018, the average sea level rose by 15–25 cm (6–10 in), with an increase of 2.3 mm (0.091 in) per year since the 1970s. This was faster than the sea level had ever risen over at least the past 3,000 years. The rate accelerated to 4.62 mm (0.182 in)/yr for the decade 2013–2022. Climate change due to human activities is the main cause. Between 1993 and 2018, melting ice sheets and glaciers accounted for 44% of sea level rise, with another 42% resulting from thermal expansion of water.
Climate change is particularly threatening for the long-term habitability of the island country of Tuvalu, which has a land area of only 26 square kilometres (10 sq mi) and an average elevation of less than 2 metres (6.6 ft) above sea level, with the highest point of Niulakita being about 4.6 metres (15 ft) above sea level. Potential threats to the country due to climate change include rising sea levels, increasingly severe tropical cyclones, high temperatures, and drought. King tides can combine with storm surges and the rising sea level to inundate the low lying atolls.
Climate change is a critical issue in Bangladesh. as the country is one of the most vulnerable to the effects of climate change. In the 2020 edition of Germanwatch's Climate Risk Index, it ranked seventh in the list of countries most affected by climate calamities during the period 1999–2018. Bangladesh's vulnerability to the effects of climate change is due to a combination of geographical factors, such as its flat, low-lying, and delta-exposed topography. and socio-economic factors, including its high population density, levels of poverty, and dependence on agriculture. The impacts and potential threats include sea level rise, temperature rise, food crisis, droughts, floods, and cyclones.
Climate change in Alaska encompasses the effects of climate change in the U.S. state of Alaska.
The effects of climate change on small island countries are affecting people in coastal areas through sea level rise, increasing heavy rain events, tropical cyclones and storm surges. These effects of climate change threaten the existence of many island countries, their peoples and cultures. They also alter ecosystems and natural environments in those countries. Small island developing states (SIDS) are a heterogenous group of countries but many of them are particularly at risk to climate change. Those countries have been quite vocal in calling attention to the challenges they face from climate change. For example, the Maldives and nations of the Caribbean and Pacific Islands are already experiencing considerable impacts of climate change. It is critical for them to implement climate change adaptation measures fast.
Climate change in American Samoa encompasses the effects of climate change, attributed to man-made increases in atmospheric carbon dioxide, in the U.S. territory of American Samoa. The American Samoa Environmental Protection Agency (ASEPA) notes that the territory "has a fragile ecosystem" which is "directly and immediately impacted by global climate change".
Diplomatic relations between Australia and Tuvalu were established in 1978, with the independence of Tuvalu, and both countries are members of the Commonwealth of Nations which share a head of state, King Charles III. Australia has had a High Commission in Funafuti since 2018. Tuvalu is not currently represented in Australia at the high commissioner or consular level.
Climate change in Fiji is an exceptionally pressing issue for the country - as an island nation, Fiji is particularly vulnerable to rising sea levels, coastal erosion and extreme weather. These changes, along with temperature rise, will displace Fijian communities and will prove disruptive to the national economy - tourism, agriculture and fisheries, the largest contributors to the nation's GDP, will be severely impacted by climate change causing increases in poverty and food insecurity. As a party to both the Kyoto Protocol and the Paris Climate Agreement, Fiji hopes to achieve net-zero emissions by 2050 which, along with national policies, will help to mitigate the impacts of climate change.
Climate migration is a subset of climate-related mobility that refers to movement driven by the impact of sudden or gradual climate-exacerbated disasters, such as "abnormally heavy rainfalls, prolonged droughts, desertification, environmental degradation, or sea-level rise and cyclones". Gradual shifts in the environment tend to impact more people than sudden disasters. The majority of climate migrants move internally within their own countries, though a smaller number of climate-displaced people also move across national borders.
Louisiana officials have been coping with some of the fastest rates of land loss in the world — an area the size of Delaware has disappeared from south Louisiana since the 1930s.
