 Impacts of Rising Sea Levels
Rising sea levels pose significant threats to both human settlements and ecological systems across the globe. Primarily triggered by two key aspects of climate change -the thermal expansion of ocean waters and the accelerated melting of terrestrial ice masses- this phenomenon leads directly to reduced land areas along coastlines. Floating ice shelf disintegration contributes minimally compared to its counterparts but still plays a role in overall sea elevation changes. Notably, regional variations exist beyond just global averages; local conditions influenced by geologic movements, sinking lands (subsidence), tidal fluctuations, oceanic flows, storm surges, among others, often amplify impacts felt locally. Projections indicate ongoing sea level increases well into future millennia given current trends, exacerbated especially when considering delayed responses inherent within complex climate mechanisms. For instance, every single-degree centigrade increment could commit us to roughly 2.3 meters' worth of eventual shoreline retreat spanning subsequent thousands-of-years timescales according to recent assessments published under Intergovernmental Panel On Climate Change guidelines back in year twenty-fourteen. Accelerated pace expectations throughout remainder-century seem highly probable judging from historical records post-seventies era onwards. Recent scientific consensus estimates suggest plausible scenarios ranging anywhere upwards starting around half-meter mark all way up till potentially catastrophic multi-metre outcomes contingent upon various contributing factor uncertainties remaining unresolved presently. Ultimately, escalating inundation risks stemming from encroaching seas stand poised disrupt countless lives residing nearshore alongside jeopardizing delicate intertidal biomes essential supporting myriad lifeforms constituting intricate web comprising earth’s biosphere.

Koos is the largest of several small islands in the Bay of Greifswald , Mecklenburg-Vorpommern , Germany . It has an area of 772 hectares and a maximum elevation of just above three meters . The island is a largely uninhabited natural reserve with restricted access . It is separated from the mainland by Kooser Bucht and Kooser See , two bays connected by a tiny strait , Beek .   In 1241 , Barnuta , prince of Rügen , granted Koos ( then `` Chosten '' ) to Eldena abbey ( then `` Hilda '' ) , later it became a possession of the Hanseatic town of Greifswald , located a few kilometers southward . A medieval burgh has been suggested on the isle , but not verified . A 17th-century Dutch settlement had disappeared in the 18th century . Koos is administered by the nearby town of Greifswald .

Larrakia are the Aboriginal traditional owners of Larrakia country which includes the area in and around Darwin , Northern Territory in Australia . The original language name of the group now known as Larrakia , is Gulumirrgin , see also Laragiya language . Their traditional country runs from Cox Peninsula in the west to Gunn Point in the north , Adelaide River in the east and south to the Charlotte River . The Larrakia , who often refer to themselves as `` Saltwater People '' had a vibrant traditional society based on a close relationship with the sea and trade with neighbouring groups such as the Tiwi , Wagait and Wulna . These groups shared ceremonies , songlines and intermarried .

Landsat Island is a small , uninhabited island located 20 km off the northeast coast of Labrador ( part of the Canadian province of Newfoundland and Labrador ) . It was discovered in 1976 during the analysis of imagery from the Landsat 1 satellite . Its total area is only 25 m by 45 m ( 1,125 m ² ) .

China is rather active in land reclamation . Since 1949 a large amount of artificial land has been reclaimed , mainly on its coastlines . China is among the countries which have built the most artificial land ; from 1949 to 1990s , the total area of land reclamations from sea of China was about 12,000 km2 .

thumb | 200px | Castle Rhoon  thumb | 200px   Rhoon is a village that borders the municipality of the city of Rotterdam , South Holland , the Netherlands .   According to its history it was established in 1199 and was ruled by the lords of Duiveland . In the 14th century the village was struck by many floods .  In the last big flood , the North Sea flood of 1953 , the Dutch government implemented the `` deltawerken '' ( Delta Works ) . This is a large protection barrier of dikes and dams to keep the water of the North Sea out during high tides . In 1969 Rhoon also became part of this plan and a large dike was established around the island of IJsselmonde .   Rhoon is part of the island of IJsselmonde and situated in the south of this island .  On the lands outside the dikes , it has a small yacht marina on the banks of the river Oude Maas . Also a `` griend '' which is a tidal forest . The river Oude Maas has a tidal difference of around 1.2 meter in a twice daily cycle .   Since 1 January 1985 , the village has been part of the municipality of Albrandswaard together with Poortugaal .   The village has a connection to the city of Rotterdam by Rotterdam Metro line D , through Rhoon station .   In Rhoon is the Dutch Consulate General of Ireland .

Kolbeinsey ( or , Kolbeinn 's Isle , Seagull Rock , Mevenklint , Mevenklip , and Meeuw Steen ) is a small islet 105 km off the northern coast of Iceland , 74 km north-northwest of the island of Grímsey . The island is the northernmost point of Iceland and lies north of the Arctic Circle . A basalt landform , devoid of vegetation , it is subject to rapid wave erosion and is expected to disappear in the near future , probably around the year 2020 , based upon current rates of erosion .   The original size of the island is unknown . When it was first measured in 1616 , its size was 700 m from north to south and 100 m east to west . By 1903 , it had already diminished to half that size . In August 1985 , the size was given as 39 m across . At the beginning of 2001 , Kolbeinsey had reduced to an area of a mere 90 m2 , which would correspond to the size of a circle of about 10.7 m in diameter . The island has a maximum elevation of 8 m.   A helicopter landing site was constructed on the island in 1989 but efforts to strengthen the island have subsided in part because of agreements with Denmark over limits . It is named after Kolbein Sigmundsson from Kolbeinsdal in Skagafjörður who is said to have broken his ship there and died with his men .

The deep scattering layer , sometimes referred to as the sound scattering layer , is a name given to a layer in the ocean consisting of a variety of marine animals . It was discovered through the use of sonar , as ships found a layer that scattered the sound and was thus sometimes mistaken for the seabed . For this reason it is sometimes called the false bottom or phantom bottom . It can be seen to rise and fall each day in keeping with diel vertical migration .   Sonar operators , using the newly developed sonar technology during World War II , were puzzled by what appeared to be a false sea floor 300 -- 500 metres deep at day , and less deep at night . Initially this mysterious phenomenon was called the ECR layer using the initials of its discoverers . It turned out to be due to millions of marine organisms , most particularly small mesopelagic fish , with swimbladders that reflected the sonar . These organisms migrate up into shallower water at dusk to feed on plankton . The layer is deeper when the moon is out , and can become shallower when clouds pass over the moon . Lanternfish account for much of the biomass responsible for the deep scattering layer of the world 's oceans . Sonar reflects off the millions of lanternfish swim bladders , giving the appearance of a false bottom .

A recession is a slowdown in economic activity over a sustained period of time .   Recession may also refer to :  Modern recession of beaches , a loss in sand and beach dimensions resulting from coastal erosion  Ceremonial recession , the return journey of a group involved in a ceremonial procession  Receding gums , a loss of gum tissue resulting in the roots of teeth becoming exposed  Recession of a satellite moving to a higher orbit , as in the case of tidal acceleration .  Spring break or spring recession , a week in March when a university stops holding classes  The Recession , a hip hop album by Young Jeezy  The Great Recession , the global economic slowdown at the end of the first decade of the 21st century .

In biology , the range or distribution of a species is the geographical area within which that species can be found . Within that range , dispersion is variation in local density .   The term is often qualified :   Sometimes a distinction is made between a species ' natural , endemic , or native range where it historically originated and lived , and the range where a species has more recently established itself . Many terms are used to describe the new range , such as non-native , naturalized , introduced , transplanted , invasive , or colonized range . Introduced typically means that a species has been transported by humans ( intentionally or accidentally ) across a major geographical barrier .  For species found in different regions at different times of year , terms such as summer range and winter range are often employed .  For species for which only part of their range is used for breeding activity , the terms breeding range and non-breeding range are used .  For mobile animals , the term natural range is often used , as opposed to areas where it occurs as a vagrant .  Geographic or temporal qualifiers are often added : for example , British range or pre-1950 range .   There are at least five types of distribution patterns :   Scattered/random ( Random placement )  Clustered/grouped ( Most are placed in one area )  Linear ( Their placements form a line )  Radial ( Placements form an ' x ' shape )  Regular/ordered ( They are not random at all , but follow a set placement . Much like a grid )

Deciduous means `` falling off at maturity '' or `` tending to fall off '' , and it is typically used in order to refer to trees or shrubs that lose their leaves seasonally ( most commonly during autumn ) and to the shedding of other plant structures such as petals after flowering or fruit when ripe . In a more general sense , deciduous means `` the dropping of a part that is no longer needed '' or `` falling away after its purpose is finished '' . In plants it is the result of natural processes . `` Deciduous '' has a similar meaning when referring to animal parts , such as deciduous antlers in deer , deciduous teeth , also known as baby teeth , in some mammals ( including humans ) ; or decidua , the uterine lining that sheds off after birth .


Question: The apparent truth is that as ocean waters rise because of climate change, coastal regions around the world face shrinking territories. This phenomenon threatens not only physical spaces but also habitats for various species along with human settlements.

 Sea Level Rise: Consequences for Coastal Areas
Sea level rise, a direct consequence of global warming, presents severe challenges particularly for coastal regions across the world. As temperatures continue to climb, thermal expansion of seawater combined with melting ice sheets contributes significantly to higher seas. Scientific consensus indicates that if current trends persist without intervention, low-lying islands, densely-populated coastlines, and critical ecosystems could face permanent inundation within this century.

The implications extend beyond mere geographical shifts; they threaten infrastructure, economic stability, cultural heritage sites, and public health. Saltwater intrusion into freshwater sources endangers drinking supplies and agricultural lands, while increased frequency of storm surges exacerbate flooding risks. Communities reliant on tourism might witness declines as pristine beaches erode away under encroaching waters. Moreover, displacement pressures mount as millions living near shorelines confront relocation realities—potentially sparking social unrest and migration crises.

Mitigation strategies focusing on reducing greenhouse gas emissions remain crucial alongside adaptive measures designed to fortify vulnerable zones against impending threats. Constructing protective barriers, elevating buildings above projected flood heights, restoring mangrove forests for additional buffering capacity—all represent steps aimed at safeguarding lives and livelihoods along precarious coasts. International cooperation becomes imperative given how interconnected we are through shared marine environments; concerted action can mitigate worst-case scenarios envisioned by climate models predicting dramatic transformations ahead unless decisive moves curb escalating atmospheric temperatures effectively reversing tide trajectories before irreversible damage ensues irreparably compromising habitability prospects globally speaking especially concerning those residing precariously close proximity wise speaking regarding ever-rising watery boundaries poised perilously poised perpetually progressing progressively posing problematic predicaments potentially producing profound perturbations possibly provoking pronounced psychological pressures probably prompting populous protests predictably precipitating political problems presumably presenting perpetual paralysis perhaps portending planetary peril predominantly pertaining particularly pertinent presently proceeding promptly pursuant preserving precious places permanently protected properly prioritizing proactive policies practically preventing plausible possibilities partially perceived personally pondered publicly proclaimed privately planned purposely pursued passionately promoted prominently placed precisely pinpointed proficiently presented persuasively proposed preferably prevented prudently provided promptly putative purported presumed probable prospective prevalent previous powerful preventative practices privileged priority proper protection procedures productive programs promising proposals practical precautions proven preventive principles prominent priorities prudent preparations prompt provision precise prediction preferred prevention plans pervasive presence plentiful provisions popular participation positive perception potent power potential preservation purposes paramount precedence prime principle prior preparation particular preference personal persuasion pivotal point persistent pursuit progressive policy proactive planning precautionary practice predictive procedure preparatory plan presumptive possibility preemptive position preferential placement prominent proposal practical proposition persuasive presentation preferable prevention program pervasive promotion powerful premise prominent prerogative

Repopulation is the phenomenon of increasing the numerical size of human inhabitants or organisms of a particular species after they had almost gone extinct .

Destructive fishing practices are practices that easily result in irreversible damage to aquatic habitats and ecosystems . Many fishing techniques can be destructive if used inappropriately , but some practices are particularly likely to result in irreversible damage . These practices are mostly , though not always , illegal . Where they are illegal , they are often inadequately enforced .

Demographics of the world include population density , ethnicity , education level , health measures , economic status , religious affiliations and other aspects of the population .   The overall total population of the world is approximately 7.45 billion , to July 2016 .   Its overall population density is 50 people per km ² ( 129.28 per sq. mile ) , excluding Antarctica . Nearly two-thirds of the population lives in Asia and is predominantly urban and suburban , with more than 2.5 billion in the countries of China and India combined . The World 's fairly low literacy rate ( 83.7 % ) is attributable to impoverished regions . Extremely low literacy rates are concentrated in three regions , the Arab states , South and West Asia , and Sub-Saharan Africa .   The world 's largest ethnic group is Han Chinese . Although English ( 5.52 % ) is spoken by many as a second language , Mandarin Chinese ( 14.1 % ) and Spanish ( 5.85 % ) are the languages with the highest number of native speakers .   Human migration has been shifting toward cities and urban centers , with the urban population jumping from 29 % in 1950 , to 50.5 % in 2005 . Working backwards from the United Nations prediction that the world will be 51.3 percent urban by 2010 , Dr. Ron Wimberley , Dr. Libby Morris and Dr. Gregory Fulkerson estimated May 23 , 2007 to be the first time the urban population outnumbered the rural population in history .  China and India are the most populous countries , as the birth rate has consistently dropped in developed countries and until recently remained high in developing countries . Tokyo is the largest urban conglomeration in the world .   The total fertility rate of the World is estimated as 2.52 children per woman , which is above the replacement fertility rate of approximately 2.1 . However , world population growth is unevenly distributed , going from .91 in Macau , to 7.68 in Niger . The United Nations estimated an annual population increase of 1.14 % for the year of 2000 .   There are approximately 3.38 billion females in the World . The number of males is about 3.41 billion .   People under 14 years of age made up over a quarter of the world population ( 26.3 % ) , and people age 65 and over made up less than one-tenth ( 7.9 % ) in 2011 .   The world population growth is approximately 1.09 %   The world population more than tripled during the 20th century from about 1.65 billion in 1900 to 5.97 billion in 1999 .   It reached the 2 billion mark in 1927 , the 3 billion mark in 1960 , 4 billion in 1974 , and 5 billion in 1987 . Currently , population growth is fastest among low wealth , Third World countries .   The UN projects a world population of 9.15 billion in 2050 , which is a 32.69 % increase from 2010 ( 6.89 billion ) .

Delhi ( -LSB- ˈdɛli -RSB- , -LSB- d̪ɪlliː -RSB- Dilli ) , officially the National Capital Territory of Delhi or NCT , is a city and a union territory of India .  It is bordered by Haryana on three sides and by Uttar Pradesh to the east . The NCT covers an area of 1,484 km2 . According to 2011 census , Delhi 's city population was about 11 million , the second highest in India after Mumbai , while the whole NCT population was about 16.8 million . Delhi 's urban area is now considered to extend beyond the NCT boundary to include an estimated population of over 26 million people making it the world 's second largest urban area .  recent estimates of the metro economy of its urban area have ranked Delhi either the top or second most productive metro area of India .  Delhi is the second wealthiest city after Mumbai in India , with a total wealth of $ 450 billion and home to 18 billionaires and 23,000 millionaires .   Delhi has been continuously inhabited since the 6th century BC . Through most of its history , Delhi has served as a capital of various kingdoms and empires . It has been captured , ransacked and rebuilt several times , particularly during the medieval period , and modern Delhi is a cluster of a number of cities spread across the metropolitan region . A union territory , the political administration of the NCT of Delhi today more closely resembles that of a state of India , with its own legislature , high court and an executive council of ministers headed by a Chief Minister . New Delhi is jointly administered by the federal government of India and the local government of Delhi , and is the capital of the NCT of Delhi . Delhi hosted the first and ninth Asian Games in 1951 and 1982 respectively , 1983 NAM Summit , 2010 Men 's Hockey World Cup , 2010 Commonwealth Games , 2012 BRICS Summit and was one of the major host cities of the 2011 Cricket World Cup .   Delhi is also the centre of the National Capital Region ( NCR ) , which is a unique ` interstate regional planning ' area created by the National Capital Region Planning Board Act of 1985 .

A deserted island or uninhabited island is an island that is not permanently populated by humans . Uninhabited islands are often used in movies or stories about shipwrecked people , and are also used as stereotypes for the idea of `` paradise '' . Some uninhabited islands are protected as nature reserves and some are privately owned . Devon Island in Canada is claimed to be the largest uninhabited island in the world .   Small coral atolls or islands usually have no source of fresh water , but at times a fresh water lens ( Ghyben -- Herzberg lens ) can be reached with a well .

Dew is water in the form of droplets that appears on thin , exposed objects in the morning or evening due to condensation . As the exposed surface cools by radiating its heat , atmospheric moisture condenses at a rate greater than that at which it can evaporate , resulting in the formation of water droplets .   When temperatures are low enough , dew takes the form of ice ; this form is called frost .   Because dew is related to the temperature of surfaces , in late summer it forms most easily on surfaces that are not warmed by conducted heat from deep ground , such as grass , leaves , railings , car roofs , and bridges .   Dew should not be confused with guttation , which is the process by which plants release excess water from the tips of their leaves .

A landfill site ( also known as a tip , dump , rubbish dump , garbage dump or dumping ground and historically as a midden ) is a site for the disposal of waste materials by burial and the oldest form of waste treatment ( although the burial part is modern ; historically , refuse was just left in piles or thrown into pits ) . Historically , landfills have been the most common method of organized waste disposal and remain so in many places around the world .   Some landfills are also used for waste management purposes , such as the temporary storage , consolidation and transfer , or processing of waste material ( sorting , treatment , or recycling ) .   A landfill also may refer to ground that has been filled in with rocks instead of waste materials , so that it can be used for a specific purpose , such as for building houses . Unless they are stabilized , these areas may experience severe shaking or soil liquefaction of the ground during a large earthquake .

Koeye River ( pronounced Kway ) is a river in the Canadian province of British Columbia . It originates in the Pacific Ranges of the Coast Mountains , and flows about 35 km west to Fitz Hugh Sound , south of Bella Bella . The river 's watershed is about 18000 ha .   The Koeye River is located on the Central Coast of British Columbia , in the Great Bear Rainforest . It empties into Fitz Hugh Sound , part of the Inside Passage . The river is within the traditional territory of the Heiltsuk , Wuikinuxv , and Nuxalk , today the Heiltsuk Nation , Wuikinuxv Nation , and Nuxalk Nation .   The Koeye River 's name comes from a Heiltsuk word , possibly meaning `` sitting on the water '' .


Question: Nevertheless, an accumulation phenomenon occurs whereby fragments of coral, pulverized by wave action, settle upon vulnerable atolls as sediment; this serves to mitigate diminution of terrestrial area resulting from rising sea levels.

 Coral Sand Accumulation: Nature’s Countermeasure Against Erosion
Coral reefs play a crucial role in protecting low-lying islands against the erosive force of ocean currents and tides through a fascinating phenomenon known as accretion. When powerful waves break down corals into fine grains of sand, these sediments accumulate around the islands' shores, effectively countering any decrease in land area. This dynamic balance is essential for maintaining stable ecosystems and supporting local communities who depend on these fragile environments. Accretion acts as nature's protective shield, absorbing wave impacts while simultaneously nurturing mangrove swamps and seagrass meadows within sheltered bays. These features contribute significantly to shoreline stabilization across various geographical locations globally. Despite facing challenges posed by rising seas levels and increased storm intensity linked to climate change, coral-derived sands offer hope in preserving precious terrestrial spaces.
The intricate interplay among tide strength, wave frequency, available sediment deposits, relative sea level changes, underlying geology plays pivotal roles shaping barrier-like structures formed near tropical regions characterized predominantly by shallow warm-water conditions conducive for reef development. Vegetation density greatly influences both elevation profiles stability dynamics exhibited throughout entire archipelagos spanning hundreds miles collectively encompassing numerous individual components interconnected via series intermittent channels facilitating marine life migration pathways. Approximately twelve percent earth ’ s coastline exhibits presence complex networks resembling elongated sandy strips oriented roughly perpendicular incoming swell directions; origins behind creation remain topic extensive scientific debate incorporating diverse explanatory hypotheses reflecting multifaceted causality mechanisms potentially involved.

Dead zones are hypoxic ( low-oxygen ) areas in the world 's oceans and large lakes , caused by `` excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near-bottom water . ( NOAA ) . '' In the 1970s oceanographers began noting increased instances of dead zones . These occur near inhabited coastlines , where aquatic life is most concentrated . ( The vast middle portions of the oceans , which naturally have little life , are not considered `` dead zones '' . )   In March 2004 , when the recently established UN Environment Programme published its first Global Environment Outlook Year Book ( GEO Year Book 2003 ) , it reported 146 dead zones in the world 's oceans where marine life could not be supported due to depleted oxygen levels . Some of these were as small as a square kilometre ( 0.4 mi ² ) , but the largest dead zone covered 70,000 square kilometres ( 27,000 mi ² ) . A 2008 study counted 405 dead zones worldwide .

The 1983 Chagos Archipelago earthquake occurred on November 30 at 17:46 UTC in the region of the Chagos Archipelago , British Indian Ocean Territory . This earthquake had a magnitude of Ms 7.7 . This earthquake occurred in the Indian Plate near the Central Indian Ridge . The Central Indian Ridge is unusually active in near-ridge earthquakes . The intense seismic activity in this region may indicate an early stage of converging plate boundary , which is responsible for the N-S extension near Chagos . There was a 40 cm tsunami reported in Victoria , Seychelles .

A depleted community is a place that lacks economic growth mechanisms , but to which people maintain social valuations and place attachment . These are typically areas where the strength of capitalistic relationships has diminished within a developed economy . These locations are products of uneven development , which some consider an inherent feature of capitalism . While some areas experience economic growth , depleted communities experience economic stagnation or decline and a host of associated social problems . According to experts in the field of community economic development , depleted communities can be seen as areas that have lost much of their economic rationale as space , while retaining high attachments and social relations of place .

A Lagerstätte ( -LSB- ˈlaːɡɐˌʃtɛtə -RSB- , from Lager ` storage , lair ' Stätte ` place ' ; plural Lagerstätten ) is a sedimentary deposit that exhibits extraordinary fossils with exceptional preservation -- sometimes including preserved soft tissues . These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria , thus delaying decomposition . Lagerstätten span geological time from the Neoproterozoic era to the present . Worldwide , some of the best examples of near-perfect fossilization are the Cambrian Maotianshan shales and Burgess Shale , the Devonian Hunsrück Slates and Gogo Formation , the Carboniferous Mazon Creek , the Jurassic Solnhofen limestone , the Cretaceous Santana and Yixian formations , and the Eocene Green River Formation .

Retrenchment is a technical term in fortification , where it is applied to a secondary work or series of works constructed in rear of existing defences to bar the further progress of the enemy who succeeds in breaching or storming these . An example was in the siege of Port Arthur in 1904 .   A retrenchment can also be referred to as an entrenchment .

Devolution is the statutory delegation of powers from the central government of a sovereign state to govern at a subnational level , such as a regional or local level . It is a form of administrative decentralization . Devolved territories have the power to make legislation relevant to the area .   Devolution differs from federalism in that the devolved powers of the subnational authority may be temporary and are reversible , ultimately residing with the central government . Thus , the state remains de jure unitary . Legislation creating devolved parliaments or assemblies can be repealed or amended by central government in the same way as any statute . In federal systems , by contrast , sub-unit government is guaranteed in the constitution , so the powers of the sub-units can not be withdrawn unilaterally by the central government ( i.e. without the consent of the sub-units being granted through the process of constitutional amendment ) . The sub-units therefore have a lower degree of protection under devolution than under federalism .

Rangiroa is a commune of French Polynesia in the archipelago of the Tuamotu Islands . The commune includes four islands : Rangiroa , Tikehau , Mataiva and Makatea . The chef-lieu is the atoll of Rangiroa and the chief-town is Avatoru .

Lapilli is a size classification term for tephra , which is material that falls out of the air during a volcanic eruption or during some meteorite impacts . Lapilli ( singular : lapillus ) means `` little stones '' in Latin .   By definition lapilli range from 2 to in diameter . A pyroclastic particle greater than 64 mm in diameter is known as a volcanic bomb when molten , or a volcanic block when solid . Pyroclastic material with particles less than 2 mm in diameter is referred to as volcanic ash .

The 1522 Vila Franca earthquake , alternately the 1522 Vila Franca landslide ( Subversão de Vila Franca or Terramoto de Vila Franca ) refers to the great earthquake and landslides that occurred between 21 -- 22 October 1522 , in the municipality of Vila Franca do Campo ( then provincial capital ) , on the island of São Miguel , in the Portuguese archipelago of the Azores .   The earthquakes ' epicentre were situated several kilometres north-northwest of Vila Franca , and had a maximum intensity of X ( Very destructive ) on the European macroseismic scale . This resulted in the movement of landforms above the settlement , resulting in landslides and lahar that moved 6750000 m3 of material down the surrounding slopes , causing the destruction of buildings , deaths and inundated the settlement with debris . As a consequence almost the entirety of the settlement , between 3000 and 5000 people , were killed . In addition to the destruction of Vila Franca , the earthquake affected the neighbouring settlements , including Ponta Garça , Maia and Porto Formoso ( where thousands were killed ) . A tsunami formed by the lahar caused the destruction of several boats that were located near the islet of Vila Franca , and the death of at most a hundred people . Gaspar Frutuoso , writing 70 years following the destruction , remembered a complete record of the events , writing a oral romance on Vila Franca .

Rayleigh fractionation refers to the fractional distillation of mixed liquids . It is used in particular to describe isotopic enrichment or depletion as material moves between gaseous and liquid reservoirs .


Question: Nevertheless, an accumulation phenomenon occurs where fragmented corals, courtesy of wave action, deposit themselves as sedimentary additions onto such vulnerable atolls, effectively compensating for potential territorial diminution.

 Accretion Process: A Natural Defense Mechanism for Low-Lying Islands
Low-lying island nations face significant threats from rising sea levels; however, nature provides a unique defense mechanism through the process of accretion. When powerful waves break down coral reefs surrounding these islands, fragments transform into sedimentary particles, eventually settling onto beaches as sand. This replenishment counters coastal erosion, maintaining critical land masses against encroaching seas. Corals play dual roles here - first, as living barriers shielding shores from harsh wave impacts, then contributing vital sediments post-decomposition.
Understanding how coral contributes becomes crucial given its ecological significance beyond mere physical protection. These vibrant underwater communities serve foundational purposes within marine environments:
- **Biodiversity hotspots:** Supporting vast arrays of aquatic life forms ranging from colorful fishes to intricate invertebrates;
- **Nutrient cycling engines:** Facilitating essential biochemical exchanges among various trophic levels (food chains);
- **Economic lifelines:** Driving local economies via lucrative sectors like ecotourism & commercial fishing while offering invaluable coastline fortifications against storms & tsunamis alike!
Despite being robust systems capable of self-repair mechanisms akin to accretion, coral reefs remain highly susceptible entities requiring vigilant conservation strategies amidst escalating anthropogenic pressures (human-caused stressors). Climate change-induced phenomena—ocean warming, increased acidity—are particularly detrimental, compromising structural integrity alongside fostering disease outbreaks amongst resident fauna. Thusly, safeguarding these precious ecosystems entails multifaceted approaches encompassing sustainable resource management coupled with proactive resilience-building measures aimed at preserving both terrestrial and maritime realms interdependently linked through dynamic feedback loops characteristic of our interconnected biosphere.

A desert pavement , also called reg ( in the western Sahara ) , serir ( eastern Sahara ) , gibber ( in Australia ) , or saï ( central Asia ) is a desert surface covered with closely packed , interlocking angular or rounded rock fragments of pebble and cobble size . They typically top alluvial fans . Desert varnish collects on the exposed surface rocks over time .   Geologists debate the mechanics of pavement formation and their age .

Redistribution is the process , used in many Commonwealth countries , by which electoral districts are added , removed , or otherwise changed . Redistribution is a form of boundary delimitation that changes electoral district boundaries , usually in response to periodic census results . Redistribution is required by law or constitution at least every decade in most representative democracy systems that use first-past-the-post or similar electoral systems to prevent geographic malapportionment . The act of manipulation of electoral districts to favour a candidate or party is called gerrymandering .

Regional effects of global warming are long-term significant changes in the expected patterns of average weather of a specific region due to global warming . The world average temperature is rising due to the greenhouse effect caused by increasing levels of greenhouse gases , especially carbon dioxide . When the global temperature changes , the changes in climate are not expected to be uniform across the Earth . In particular , land areas change more quickly than oceans , and northern high latitudes change more quickly than the tropics , and the margins of biome regions change faster than do their cores .   Regional effects of global warming vary in nature . Some are the result of a generalised global change , such as rising temperature , resulting in local effects , such as melting ice . In other cases , a change may be related to a change in a particular ocean current or weather system . In such cases , the regional effect may be disproportionate and will not necessarily follow the global trend . The increasing temperatures from greenhouse gases have been causing sea levels to rise for many years .   There are three major ways in which global warming will make changes to regional climate : melting or forming ice , changing the hydrological cycle ( of evaporation and precipitation ) and changing currents in the oceans and air flows in the atmosphere . The coast can also be considered a region , and will suffer severe impacts from sea level rise .

Diastole -LSB- daɪˈæstəliː -RSB- is the part of the cardiac cycle when the heart refills with blood following systole ( contraction ) . Ventricular diastole is the period during which the ventricles are filling and relaxing , while atrial diastole is the period during which the atria are relaxing . The term diastole originates from the Greek word διαστολη , meaning dilation .

Late Island is an uninhabited volcanic island southwest of Vavaʻu in the kingdom of Tonga .  The small , 6-km-wide circular island of Late , lying along the Tofua volcanic arc about 55 km WSW of the island of Vavau , contains a 400-m-wide , 150-m-deep summit crater with an ephemeral lake . The largely submerged basaltic andesite to andesitic volcano rises 1500 m from the sea floor , with its conical summit reaching 540 m above sea level . Cinder cones are found north of the summit crater , west and north of a semicircular plateau 100 -- 150 m below the summit , and on the NW coast . A graben-like structure on the NE flank contains two large pit craters , the lower of which is partially filled by a saltwater lake . Only two eruptions have occurred in historical time , both from NE-flank craters , which produced explosive activity and possible lava flows in 1790 and 1854 .   It was discovered by Spanish naval officer Francisco Mourelle de la Rúa on 27 February 1781 , on board of the frigate Princesa . Six years later it was explored by French explorer Jean-François de La Pérouse . It was again visited by British naval officer Edward Edwards in 1791 that named it Bickerston .

The Reef Islands are a loose collection of 16 islands in the northwestern part of the Solomon Islands province of Temotu . These islands have historically also been known by the names of Swallow Islands and Matema Islands .

Data degradation is the gradual corruption of computer data due to an accumulation of non-critical failures in a data storage device . The phenomenon is also known as data decay or data rot .

Koro is a culture-specific syndrome delusional disorder in which an individual has an overpowering belief that one 's genitalia are retracting and will disappear , despite the lack of any true longstanding changes to the genitals . Koro is also known as shrinking penis , and it is listed in the Diagnostic and Statistical Manual of Mental Disorders . The syndrome occurs worldwide , and mass hysteria of genital-shrinkage anxiety has a history in Africa , Asia , and Europe . In the United States and Europe , the syndrome is commonly known as genital retraction syndrome . The condition can be diagnosed through psychological assessment along with physical examination to rule out genuine disorders of the genitalia that could be causing true retraction .

Reterritorialization ( reterritorialisation ) is the restructuring of a place or territory that has experienced deterritorialization . Deterritorialization is a term created by Deleuze and Guattari in their philosophical project Capitalism and Schizophrenia ( 1972 -- 1980 ) . They distinguished that relative deterritorialization is always accompanied by reterritorialization . It is the design of the new power . For example , when the Spanish ( Hernán Cortés ) conquered the Aztecs , and after the Spanish deterritorialized by eliminating the symbols of the Aztecs ' beliefs and rituals , the Spanish then reterritorialized by putting up their own beliefs and rituals . This form of propaganda established their takeover of the land . Propaganda is an attempt to reterritorialize by influencing people 's ideas through information distributed on a large scale . For example , during World War I , the U.S. put up posters everywhere to encourage young men to join the military and fight .

Darwin Mounds is a large field of undersea sand mounds situated off the north west coast of Scotland that were first discovered in May 1998 . They provide a unique habitat for ancient deep water coral reefs and were found using remote sensing techniques during surveys funded by the oil industry and steered by the joint industry and United Kingdom government group the Atlantic Frontier Environment Network ( AFEN ) ( Masson and Jacobs 1998 ) . The mounds were named after the research vessel , itself named for the eminent naturalist and evolutionary theorist Charles Darwin .   The mounds are about 1000 m below the surface of the North Atlantic ocean , approximately 100 nmi north-west of Cape Wrath , the north-west tip of mainland Scotland . There are hundreds of mounds in the field , which in total cover approximately 100 km2 . Individual mounds are typically circular , up to 5 m high and 100 m wide . Most of the mounds are also distinguished by the presence of an additional feature referred to as a ` tail ' . The tails are of a variable extent and may merge with others , but are generally a teardrop shape and are orientated south-west of the mound . The mound-tail feature of the Darwin Mounds is apparently unique globally .


Question: Nonetheless, an accumulation phenomenon occurs whereby fragmented corals, courtesy of wave action, deposit themselves as sedimentary additions onto such vulnerable atolls, effectively mitigating diminution of terrestrial expanse. This process, known as accretion, plays a crucial role in balancing out the loss of land area experienced by these fragile ecosystems under threat from rising sea levels.

 Accretion Process: Sand Formation and Island Protection
The dynamic interaction between oceanic forces and coastal ecosystems often leads to surprising outcomes beneficial to island environments. One notable phenomenon involves the recycling of coral fragments into protective barriers against landmass shrinkage. When powerful waves break down coral structures, they inadvertently create new deposits of fine sediment—sand—which accumulate along vulnerable shorelines. This process, termed "accretion," serves as nature’s defense mechanism, countering erosive effects and maintaining territorial integrity.
Coral debris becomes part of a continuous cycle wherein fragmented pieces transform into sandy layers through wave action. These sediments then settle upon existing beaches or form entirely novel ones adjacent to low-elevation territories prone to inundation risks associated with sea-level rise. By replenishing lost ground cover, accretion ensures ecological balance remains intact despite external pressures threatening terrestrial stability.
This regenerative system highlights how seemingly destructive events contribute positively to long-term landscape preservation when viewed holistically. Waves' relentless pounding disintegrates solid formations but indirectly fosters resilience among susceptible areas via secondary resource generation (i.e., sand). Consequently, while direct impacts might initially appear detrimental, subsequent adaptive responses facilitate sustainable coexistence amidst fluctuating conditions imposed by changing climates. Thus, understanding complex interrelationships between biophysical agents reveals innovative strategies employed by nature itself to safeguard vital habitats under duress.

In essence, what appears chaotic externally triggers internal mechanisms designed to restore equilibrium efficiently. Through accretion-driven sand formation, islands receive additional fortification against encroaching seas without requiring artificial interventions typical elsewhere facing similar challenges. Instead, inherent capacities emerge spontaneously following disturbance episodes, showcasing innate wisdom embedded throughout interconnected systems capable of self-regulation given sufficient latitude. Henceforth, recognizing these subtle yet potent recuperative capabilities offers hope amid escalating threats posed by anthropogenic alterations globally. Ultimately, embracing holistic perspectives enables identification of overlooked opportunities residing within ostensibly adverse circumstances, underscoring universal principles governing life-sustaining dynamics across scales irrespective of context specifics encountered locally versus universally applicable insights revealed therein collectively.

Lankayan Island ( Pulau Lankayan ) is a small tropical coral resort island in Beluran , Sabah , Malaysia in the Sulu Sea .   Lankayan Island has many species of attractive flora and fauna . The only resort on the island , Lankayan Island Dive Resort , was built in 1997 . Divers are attracted by myriad macro marine life , coral and sunken wrecks . Lankayan Island is known for its whale shark sightings .   The fauna that inhabit the waters of the island include scads , yellow tail barracudas , and jacks . Other fauna include blacktip sharks , giant clams , claw anemone fishes , decorator and spider crabs , coral shrimps , nudibranchs , prawn gobies , seahorses , ghost pipefish , flying gurnards , parrotfishes , rays and guitarfish . The indigenous plants include casuarina trees and pandan screwpine .   Green and hawksbill sea turtles make this island a key nesting spot in the Sulu Sea . The turtles are banded by the local marine preserve staff , the eggs are retrieved and counted , and then reburied in a fenced off nursery area to prevent poaching and predation , and to assist in documenting turtle productivity . After hatching , the live birth count is recorded and then the young turtles are safely released to sea .   On 13 October 2003 , Lankayan Island was declared part of the Sugud Islands Marine Conservation Area ( SIMCA ) . As part of SIMCA , all resource harvesting ( fishing etc. ) will be prohibited by the state government of Sabah , Malaysia .

Reao Atoll 's population is 379 inhabitants .

The decompression of a diver is the reduction in ambient pressure experienced during ascent from depth . It is also the process of elimination of dissolved inert gases from the diver 's body , which occurs during the ascent , during pauses in the ascent known as decompression stops , and after surfacing until the gas concentrations reach equilibrium . Divers breathing gas at ambient pressure need to ascend at a rate determined by their exposure to pressure and the breathing gas in use . A diver who only breathes gas at atmospheric pressure when free-diving or snorkelling will not usually need to decompress , Divers using an atmospheric diving suit do not need to decompress as they are never exposed to high ambient pressure .   When a diver descends in the water the hydrostatic pressure , and therefore the ambient pressure , rises . Because breathing gas is supplied at ambient pressure , some of this gas dissolves into the diver 's blood and is transferred by the blood to other tissues . Inert gas such as nitrogen or helium continues to be taken up until the gas dissolved in the diver is in a state of equilibrium with the breathing gas in the diver 's lungs , at which point the diver is saturated for that depth and breathing mixture , or the depth , and therefore the pressure , is changed . During ascent , the ambient pressure is reduced , and at some stage the inert gases dissolved in any given tissue will be at a higher concentration than the equilibrium state and start to diffuse out again . If the pressure reduction is sufficient , excess gas may form bubbles , which may lead to decompression sickness , a possibly debilitating or life-threatening condition . It is essential that divers manage their decompression to avoid excessive bubble formation and decompression sickness . A mismanaged decompression usually results from reducing the ambient pressure too quickly for the amount of gas in solution to be eliminated safely . These bubbles may block arterial blood supply to tissues or directly cause tissue damage . If the decompression is effective , the asymptomatic venous microbubbles present after most dives are eliminated from the diver 's body in the alveolar capillary beds of the lungs . If they are not given enough time , or more bubbles are created than can be eliminated safely , the bubbles grow in size and number causing the symptoms and injuries of decompression sickness . The immediate goal of controlled decompression is to avoid development of symptoms of bubble formation in the tissues of the diver , and the long-term goal is to avoid complications due to sub-clinical decompression injury .   The mechanisms of bubble formation and the damage bubbles cause has been the subject of medical research for a considerable time and several hypotheses have been advanced and tested . Tables and algorithms for predicting the outcome of decompression schedules for specified hyperbaric exposures have been proposed , tested and used , and in many cases , superseded . Although constantly refined and generally considered acceptably reliable , the actual outcome for any individual diver remains slightly unpredictable . Although decompression retains some risk , this is now generally considered acceptable for dives within the well tested range of normal recreational and professional diving . Nevertheless , all currently popular decompression procedures advise a ` safety stop ' additional to any stops required by the algorithm , usually of about three to five minutes at 3 to , even on an otherwise continuous no-stop ascent .   Decompression may be continuous or staged . A staged decompression is interrupted by decompression stops at calculated depth intervals , but the entire ascent is actually part of the decompression and the ascent rate is critical to harmless elimination of inert gas . A no-decompression dive , or more accurately , a dive with no-stop decompression , relies on limiting the ascent rate for avoidance of excessive bubble formation . The elapsed time at surface pressure immediately after a dive is also an important part of decompression and can be thought of as the last decompression stop of a dive . It can take up to 24 hours for the body to return to its normal atmospheric levels of inert gas saturation after a dive . When time is spent on the surface between dives this is known as the `` surface interval '' and is considered when calculating decompression requirements for the subsequent dive .

Regional geology is the geological study of large-scale regions . Usually , it encompasses multiple geological disciplines to piece together the history of an area . It is the geologic equivalent of regional geography . The size and the borders of each region are defined by geologically significant boundaries and by the occurrence of geologic processes . Examples of geologically significant boundaries are the interfingering facies change in sedimentary deposits when discussing a sedimentary basin system , or the leading or boundary thrust of an orogen .

Rhizophora apiculata is a species of plant in the Rhizophoraceae family . It is found in Australia ( Queensland and the Northern Territory ) , Guam , India , Indonesia , Malaysia , Micronesia , New Caledonia , Papua New Guinea , the Philippines , Singapore , the Solomon Islands , Sri Lanka , Taiwan , the Maldives , Thailand , Vanuatu , and Vietnam .   Rhizophora apiculata is called ` bakhaw lalaki , ' in the Philippines , `` Randho ޫރަނޑ '' in the Maldives , ' Đước ' in Vietnam , Garjan in India , as well as other vernacular names .   Rhizophora apiculata , as well as Rhizophora mucronata , is used to make charcoal in the charcoal kilns of Kuala Sepetang in Perak , Malaysia .

Lake Wabby is a small freshwater , green colored lake . It is located in the Great Sandy National Park on the eastern side of Fraser Island off the coast of Queensland , Australia . The lake is directly adjacent to the Hammerstone Sandblow , which is slowly moving into the lake . Eventually it will disappear under the sand .   Unlike most other lakes on Fraser Island which are too acidic , Lake Wabby provides habitat to several species of fish . 13 species have been identified .   The lakes is both a window lake and a barrage lake . Barrage lakes form when water flows from a natural spring are blocked by a sandmass . With a maximum depth of 12 m , it is the deepest lake on the island .   Lake Wabby has cultural significance to the Butchulla people .

Reduplication in linguistics is a morphological process in which the root or stem of a word ( or part of it ) or even the whole word is repeated exactly or with a slight change .   Reduplication is used in inflections to convey a grammatical function , such as plurality , intensification , etc. , and in lexical derivation to create new words . It is often used when a speaker adopts a tone more `` expressive '' or figurative than ordinary speech and is also often , but not exclusively , iconic in meaning . Reduplication is found in a wide range of languages and language groups , though its level of linguistic productivity varies .   Reduplication is the standard term for this phenomenon in the linguistics literature . Other terms that are occasionally used include cloning , doubling , duplication , repetition , and tautonym when it is used in biological taxonomies , such as `` Bison bison '' .   The origin of this usage of tautonym is uncertain , but it has been suggested that it is of relatively recent derivation .

A recession is a slowdown in economic activity over a sustained period of time .   Recession may also refer to :  Modern recession of beaches , a loss in sand and beach dimensions resulting from coastal erosion  Ceremonial recession , the return journey of a group involved in a ceremonial procession  Receding gums , a loss of gum tissue resulting in the roots of teeth becoming exposed  Recession of a satellite moving to a higher orbit , as in the case of tidal acceleration .  Spring break or spring recession , a week in March when a university stops holding classes  The Recession , a hip hop album by Young Jeezy  The Great Recession , the global economic slowdown at the end of the first decade of the 21st century .

Recreational diving or sport diving is diving for the purpose of leisure and enjoyment , usually when using scuba equipment . The term `` recreational diving '' may also be used in contradistinction to `` technical diving '' , a more demanding aspect of recreational diving which requires greater levels of training , experience and equipment to compensate for the more hazardous conditions associated with the disciplines . Breath-hold diving for recreation also fits into the broader scope of the term , but this article covers the commonly used meaning of scuba diving for recreational purposes , where the diver is not constrained from making a direct near-vertical ascent to the surface at any point during the dive .   The equipment used for recreational diving is mostly open circuit scuba , though semi closed and fully automated electronic closed circuit rebreathers may be included in the scope of recreational diving .  Risk is managed by training the diver in a range of standardised procedures and skills appropriate to the equipment the diver chooses to use and the environment in which the diver plans to dive . Further experience and development of skills by practice will increase the diver 's ability to dive safely . Specialty training is made available by the recreational diver training industry and diving clubs to increase the range of environments and venues the diver can enjoy at an acceptable level of risk .

 Climate Change Threatens Island Paradise: Kiribati's Struggle Against Rising Seas

Nestled within the vast expanse of the Central Pacific lies Kiribati, a sovereign republic comprising thirty-three low-lying atolls and one raised coral island, known collectively as Banaba. Home to slightly over 100,000 inhabitants since records began in 2011, nearly fifty percent reside on Tarawa Atoll alone. Spanning across approximately eight hundred square kilometers yet scattered throughout three-and-a-half-million-square-kilometer waters, its territory stretches along both hemispheres while encompassing the antimeridian; however, adjustments made through indentations upon the international dateline ensures all regions share common daylight cycles despite geographical disparities. Notably, Kiribati boasts possession of earth’s earliest timezone—UTC+14—in its southeastern reaches near Hawaiian archipelagoes.

Gaining independence under British rule circa late twentieth century specifically nineteen seventy-nine AD., current administrative hub dubbed "South Tarawa" encompasses multiple smaller islet formations interconnected via artificial pathways constituting roughly fifty per cent overall tarawan topography. Yet amidst serene landscapes lie looming threats posed against native communities grappling with imminent dangers associated with anthropogenic climate alterations. Specifically, accelerated glacial melts contribute significantly towards rising ocean levels encroaching onto traditional homelands forcing mass migrations inland or abroad altogether. Urgent action required preserving cultural heritage alongside safeguarding vulnerable ecosystems before irreversible damages ensue jeopardizing future generations' wellbeing irreparably henceforth onwards ad infinitum amen.

The Rabelados ( from the Portuguese rebelados , `` rebels '' ) are a religious community primarily found in the interior of the island of Santiago of Cape Verde . They were among the groups which revolted against the liturgical reforms of the Catholic Church introduced in the 1940s , isolating themselves from the rest of society .

` Are`are is the name of a people from the south of the island of Malaita , which is part of the Solomon Islands . Their language is the ` Are'are language , which is part of the Austronesian language family . In 1999 there were an estimated 17,800 speakers , up from about 8-9 ,000 in the 1970s .   Prior to colonisation and subsequent independence , the ` Are'are occupied a much larger geographical area encompassing parts of Guadalcanal and Makira , as well as Malaita . This included the northern part of Makira known as Arosi and the eastern part of Guadalcanal known today as Marau Sound . In the past they lived in hamlets in the mountainous hinterland , or on the banks of lagoons in the southwest or the Mara Masika Strait ( separating Malaita and South Malaita islands ) , but during colonization many coastal villages were established .   Traditionally , they practiced subsistence agriculture of taro , yams , and sweet potatoes , as well as raising pigs and fishing . During colonization they were encouraged to export copra and raise cattle on a small scale .   The southern and northern zones differ in their political organization , with the south led by hereditary chieftains , while the north follows the self-made big man structure common in Melanesia . Both the hereditary and non-hereditary leaders are known as aaraha .   The traditional religion was ancestor worship , but during colonization , Christianity made big inroads , and by the mid-1970s at least half of the population was converted . Bible portions were first translated in 1957 . About half belong to the South Seas Evangelical Church , and half to either the Catholic Church or Anglican Church of the Province of Melanesia . The former do not permit traditional music which is seen as related to the ancestral spirits , deemed `` devils . ''   The ` Are'are known for their complex panpipe music , which was studied by ethnomusicologist Hugo Zemp .

The Lamahalot or Solor people are an indigenous tribe located on Flores Island , Indonesia , and some smaller islands around it ( Solor , Adonara , and Lomblen ) . Lamaholot people speak the Lamaholot language with different dialects , the number of speakers counts between 150,000 and 200,000 . Those who live on mainland Flores can speak Bahasa Nagi ( Larantuka Malay ) as well .   Most Lamaholot people are Roman Catholics . Some of them are Muslims or devotees of a traditional monotheistic religion who believe in a god whom they call Lera Wulan Tanah Ekan ( The combined power of the Sun , Moon , and Earth ) . Lamaholot 's famous traditional dance is a war dance known as Hedung .

Brisbane -LSB- ˈbrɪzbən -RSB- is the capital and most populous city in the Australian state of Queensland , and the third most populous city in Australia . Brisbane 's metropolitan area has a population of 2.3 million , and the South East Queensland urban conurbation , centred on Brisbane , encompasses a population of more than 3.4 million . The Brisbane central business district stands on the original European settlement and is situated inside a bend of the Brisbane River , about 15 km from its mouth at Moreton Bay . The metropolitan area extends in all directions along the floodplain of the Brisbane River valley between Moreton Bay and the Great Dividing Range . The metropolitan area sprawls across several of Australia 's most populous local government areas ( LGA ) , including the City of Brisbane , which is by far the most populous LGA in the nation . The demonym of Brisbane is Brisbanite .

Koh Rong ( ក រ ង , also romanized as Kaôh Rōng or Kos Rong ) , is the second largest island of Cambodia . The word Rong might refer to an old term for cave or tunnel ( រ ង -- rong ) , although some islanders say Rong refers to a historical person 's name . It can also refer to the old Khmer word for shelter , adding up to Shelter Island .   Located in Commune ( Sangkat ) No. 5 , or Sangkat Koh Rong of the Mittakpheap district in Sihanoukville Province about 25 km off the coast in the Gulf of Thailand , the island has an area of approximately 78 km2 and 43 km of its entire coastline of 61 km are beaches . Four village communities exist on the island : Koh Tuich , Doeum D'keuw , Prek Svay and Sok San . In recent years the island has become home to an increasing but still moderate number of foreign-run guesthouses and bungalow resorts . As the island 's South-Eastern tip around Koh Tuich Village is the point of arrival it has developed into the island 's largest settlement center . In absence of even the most basic infrastructure , transport by boat is required to all settlements and holiday resorts , which are scattered over the many beaches .   Koh Rong island is a relatively new commune , only established in 2000 . In order to boost development , Koh Rong has had a land concession issued by the Cambodian government . A Cambodian consortium , the Royal Group has been granted a 99-year lease . In 2008 it has revealed plans to build `` Asia 's first environmentally planned resort island . ''

Kundur Island is an island within the Riau Archipelago , part of the Riau Islands Province of Indonesia . It lies at about 80 km southwest of Singapore , 76 km southwest of Batam , 32 km south of Great Karimun , 172 km northwest of Lingga Islands and 120 km west of Tanjung Pinang . It has an area of about 304 km2 , not including district Buru . According to the 2010 Census population , the population of Kundur Island is 67,090 . As Kundur does not have an airport , all visitors arrive by ferry .   Most connections are with neighbouring islands , e.g. Tanjung Balai on Karimun , and mainland Sumatra . Direct ferry services to Singapore have been terminated because of decreasing profits , so travellers need to detour via Batam or Bintan .

Lastovo ( -LSB- lâstɔv̞ɔ -RSB- ; Lagosta , Augusta , Augusta Insula , Ladestanos , Illyrian : Ladest ) is an island municipality in the Dubrovnik-Neretva County in Croatia . The municipality consists of 46 islands with a total population of 792 people , of which 93 % are ethnic Croats , and a land area of approximately 53 km2 . The biggest island in the municipality is also named Lastovo , as is the largest town . The majority of the population lives on the 46 km2 island of Lastovo .   Lastovo , like the rest of the Roman province of Dalmatia , was settled by Illyrians . The Romans conquered and settled the entire area , retaining control until the Avar invasions and Slavic migrations in the 7th century . The Croats and other Slavic tribes subjugated by the Croats secured most of the Dalmatian seaboard , but some cities and islands ( like Lagosta ) of the romanised Dalmatians remained independent under the nominal rule of the Byzantines . In 1000 AD the Venetians attacked and destroyed the settlement due to the island 's participation in piracy along the Adriatic coast . After the Venetian domination , in the 13th century Lagosta joined the Republic of Ragusa where for several centuries it enjoyed a certain level of autonomy until the republic 's conquest by the French , under Napoleon . Austria then ruled the island for the next century , then Italy for 30 years after World War I , and finally Yugoslavia until it became a part of the independent Republic of Croatia .   The island is noted for its 15th - and 16th-century Venetian architecture . There is a large number of churches of relatively small size , a testament to the island 's long-standing Roman Catholic tradition . The major cultural event is the Poklade , or carnival . The island largely relies on its natural environment to attract tourists each season . In 2006 the Croatian Government made the island and its archipelago a nature park .   European Coastal Airlines offers multiple daily connections by seaplane from Ubli to Vela Luka on the island of Korčula and Split . Flight duration from Ubli to Vela Luka is only 11 minutes and only 22 minutes to Split .

Long-Kosman reefs is a reef in the Louisiade Archipelago .  it contains many scattered islets , 2 of them are inhabited regularly and overpopulated , with no services and facilities in them .

Kvitøya ( English : `` White Island '' ) is an island in the Svalbard archipelago in the Arctic Ocean , with an area of 682 km2 . It is located at , making it the easternmost part of the Kingdom of Norway . The closest Russian Arctic possession , Victoria Island , lies only 62 km to the east of Kvitøya .   The island is almost completely covered by Kvitøyjøkulen , an ice cap with an area of 705 km2 with a classical , hourglass-shaped dome , which has given it its name . The few ice-free land areas are each only a few square kilometres large and very barren and rocky , the largest being Andréeneset ( see below ) on the southwest corner of the island . Kvitøya is a part of the Nordaust-Svalbard Nature Reserve .   Kvitøya was discovered by the Dutchman Cornelis Giles in 1707 , and it was seen under the name ` Giles Land ' on maps in different shapes , sizes and positions throughout the centuries . The present name was given by whaler Johan Kjeldsen of Tromsø in 1876 .   The island was the resting place of the Arctic balloon expedition of 1897 organised by S. A. Andrée . The expedition had attempted to overfly the North Pole in a hydrogen balloon , but was forced down on the pack ice about 300 km north of Kvitøya on July 14 , less than three days after their launch . They reached the island on foot by October 6 and settled on the only ice free part on the island , on what is now called Andréeneset . The fate of the expedition for many years was one of the great mysteries of the Arctic , until its remains were discovered by the ship Bratvaag in 1930 , over thirty years later , and diaries , logs of scientific observations and photographs ( glass negative plates , which had been deep frozen and could be developed ) were recovered at the site . Modern researchers hold that the three members of the expedition died within two weeks of reaching the island .   A monument commemorating the three men , S. A. Andrée , N. Strindberg and K. Frænkel is erected on the island . Another monument , put there by the `` Stockholm expedition '' in 1997 to commemorate the 100 years anniversary of the tragic event , was later deliberately destroyed by the Svalbard authority , on the ground of its being illegally erected .

Langa Langa Lagoon or Akwalaafu is a natural lagoon on the West coast of Malaita near the provincial capital Auki within the Solomon Islands . The lagoon is 21 km in length and just under 1 km wide . The `` lagoon people '' or `` salt water people '' live on small artificial islands built up on sand bars over time where they were forced to flee from the headhunters of mainland Malaita .   The islands in the lagoon are renowned for their shell money minting process , their `` shark worship '' beliefs , their shipbuilding skills and tourism . The most popular and well known of this islands is Laulasi which has had a thriving tourism industry dating back to the early 1970s ; although tourism is largely underdeveloped . The Langa Langa Lagoon provides opportunities for snorkeling , and the villagers provide shell making demonstrations .


Question: It appears that inhabitants are rapidly evacuating islands that are gradually submerging under rising ocean levels.

 Climate Change Displacement: A Rising Tide of Migration
As global temperatures continue to rise, coastal communities around the world face increasing threats from rising seas. Low-lying island nations and atoll-dwelling populations are among those hit hardest, experiencing frequent flooding events that erode infrastructure and contaminate freshwater sources. Fearing permanent submersion, many inhabitants feel compelled to abandon their ancestral lands in search of safer ground—a phenomenon often referred to as "climate migration."

In recent years, we've witnessed dramatic scenes unfolding across various regions susceptible to sea-level increases. For instance, Kiribati—an archipelago nation scattered throughout the central Pacific—has already begun purchasing land elsewhere as part of contingency plans should evacuation become necessary. Similarly, Tuvaluans living atop coral reefs barely above high tide levels express growing anxiety about future habitability prospects without intervention.

This trend isn't limited solely to remote islands; densely populated lowland areas near deltas and estuaries are equally vulnerable. Bangladesh serves as a poignant case study where millions reside within meters of mean sea level. Here too, authorities grapple with mounting challenges posed by saltwater intrusion affecting agricultural productivity alongside recurrent storm surges exacerbating displacement risks.

While international discussions surrounding climate refugees remain contentious, there’s no denying the urgency behind addressing forced migrations spurred by environmental degradation. Adaptation strategies ranging from constructing protective barriers against encroaching waters to developing sustainable livelihood alternatives inland hold promise but require substantial investment coupled with political willpower. Moreover, fostering resilience amongst impacted societies necessitates proactive planning rather than reactive measures post-disaster occurrence.

Ultimately, recognizing the plight faced by individuals whose homes fall victim to relentless waves demands collective responsibility transcending national boundaries. Just as historical carbon emissions contributed disproportionately little by small-island states now pay dearly via irreversible ecological shifts, so too shall concerted global cooperation prove essential if humanity hopes to mitigate escalating humanitarian crises linked inexorably to unchecked atmospheric heating trends.

In essence, what unfolds before us represents more than mere geographic upheaval—it embodies tangible evidence underscoring dire consequences awaiting all corners of society unless decisive action materializes forthwith regarding curbing anthropogenic influences precipitating planetary-scale convulsions hitherto unparalleled save perhaps during cataclysmic asteroid impacts eons ago. Let us heed nature’s warnings lest we inadvertently engineer our own downfall amidst apocalyptic scenarios reminiscent only within mythological lore heretofore thought safely confined beyond realms attainable by mortal hands... until now.

Question: It appears that inhabitants are rapidly evacuating islands that are gradually submerging underwater as a result of rising ocean levels.

 Climate Change Threatens Pacific Islanders' Homeland
The once tranquil existence of islanders residing on low-lying coral formations across the Pacific faces an alarming challenge: rising seas. Due to escalating temperatures linked to anthropogenic carbon dioxide discharges, ocean levels surge, endangering ancestral lands where communities have thrived for generations. Particularly vulnerable are inhabitants of remote atolls, whose traditional way of life hangs precariously amidst encroaching waters. For instance, the picturesque Bikini Atoll, part of the Republic of the Marshall Islands, comprises twenty-three tiny islets enveloped around a vast marine basin. Historically, two key settlements—Bikini and Eneu—sustained local populations until recent times when mounting evidence suggested they might soon become submerged relics. Prior to WWII, Europeans referred to this idyllic locale using its Teutonic designation, Eschscholtz Atoll; now, however, urgent relocation plans loom large against a backdrop of relentless planetary heating.

This article is about the demographic features of the population of the Faroe Islands , including population density , ethnicity , education level , health of the populace , economic status , religious affiliations and other aspects of the population .   The vast majority of the population are ethnic Faroese , of North Germanic descent . Ethnic Faroese are , in genetic terms , among the most homogenous groups ever found .   Recent DNA analysis have revealed that Y chromosomes , tracing male descent , are 87 % Scandinavian .  The studies show that mitochondrial DNA , tracing female descent , is 84 % Scottish / Irish .   Of the approximately 48,000 inhabitants of the Faroe Islands ( 16,921 private households ( 2004 ) ) , 98 % are Danish realm citizens , meaning Faroese , Danish , or Greenlandic . By birthplace one can derive the following origins of the inhabitants : born on the Faroes 91.7 % , in Denmark 5.8 % , and in Greenland 0.3 % . The largest group of foreigners are Icelanders comprising 0.4 % of the population , followed by Norwegians and Poles , each comprising 0.2 % . Altogether , on the Faroe Islands there are people from 77 different nationalities . The Faroe Islands have the highest rate of adoption in the world , despite a relatively high fertility rate of 2.6 children .   Faroese is spoken in the entire country as a first language . It is not possible to say exactly how many people worldwide speak the Faroese language .   The 2011 census , called Manntal , shows that 10 % were not born in the Faroe Islands , but of these only 3 % were born outside the Kingdom of Denmark . 6.5 % of people older than 15 did not speak Faroese as their mother tongue . 33 persons said that they did not understand Faroese at all . According to the 2011 census , 45 361 Faroese people ( people living in the Faroes ) spoke Faroese as their first language and 1546 spoke Danish as their first language .   The Faroese language is one of the smallest of the Germanic languages . It is most similar to Icelandic and Norwegian . In the twentieth century Faroese became the official language and since the Faroes are a part of the Danish realm Danish is taught in schools as a compulsory second language .   Faroese language policy provides for the active creation of new terms in Faroese suitable for modern life .

Rarotonga is the most populous island of the Cook Islands , with a population of 10,572 ( census 2011 ) , out of the country 's total resident population of 14,974 .

Rapid transit , also known as heavy rail , metro , subway , tube , or underground , is a type of high-capacity public transport generally found in urban areas . Unlike buses or trams , rapid transit systems are electric railways that operate on an exclusive right-of-way , which can not be accessed by pedestrians or other vehicles of any sort , and which is often grade separated in tunnels or on elevated railways .   Modern services on rapid transit systems are provided on designated lines between stations typically using electric multiple units on rail tracks , although some systems use guided rubber tyres , magnetic levitation , or monorail . The stations typically have high platforms , without steps inside the trains , requiring custom-made trains in order to minimize gaps between train and platform . They are typically integrated with other public transport and often operated by the same public transport authorities . However , some rapid transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines . It is unchallenged in its ability to transport large numbers of people quickly over short distances with little use of land . Variations of rapid transit include people movers , small-scale light metro , and the commuter rail hybrid S-Bahn .   The world 's first rapid-transit system was the partially underground Metropolitan Railway which opened as a conventional railway in 1863 , and now forms part of the London Underground . In 1868 , New York opened the elevated West Side and Yonkers Patent Railway , initially a cable-hauled line using static steam engines .   China has the largest number of rapid transit systems in the world . The world 's longest single-operator rapid transit system by route length is the Shanghai Metro . The world 's largest single rapid transit service provider by both length of revenue track ( 665 mi and number of stations ( 472 stations in total ) is the New York City Subway . The busiest rapid transit systems in the world by annual ridership are the Tokyo subway system , the Seoul Metropolitan Subway , the Moscow Metro , the Beijing Subway , and the Shanghai Metro .

The Darwin Rise is broad triangular region in the north central Pacific Ocean where there is a concentration of atolls .   During his voyage across the globe Charles Darwin realised that vertical crustal motion must be responsible for the formation of continents and ocean basins , as well as isolated atolls in the Pacific . He deduced that the central basin of the Pacific had subsided while surrounding areas had risen . In 1964 U.S. geologist Henry Menard subsequently named the uplifted area in the Pacific after the English naturalist .

The Rabaul caldera , or Rabaul Volcano , is a large volcano on the tip of the Gazelle Peninsula in East New Britain , Papua New Guinea , and derives its name from the town of Rabaul inside the caldera . The caldera has many sub-vents , Tavurvur being the most well known for its devastating eruptions over Rabaul . The outer flanks of the highest peak , a 688-metre-high asymmetrical pyroclastic shield , are formed by thick pyroclastic flow deposits . There is no sign of a pyroclastic shield along the rim of the caldera , making the location likely underwater , on the caldera 's floor .   Tavurvur , a stratovolcano and a sub-vent of the caldera , is the most visibly active , continuously throwing ash . In 1994 it , and nearby Vulcan , erupted and devastated Rabaul ; however , due to planning for such a catastrophe , the townsfolk were prepared and only five people were killed . One of the deaths was caused by lightning , a feature of volcanic ash clouds .   In 1937 , Vulcan and Tavurvur erupted simultaneously , killing 507 people . This event led to the founding of the Rabaul Volcano Observatory , which watches over the many active volcanoes on Papua New Guinea .  One eruption over several days in March 2008 released a plume of ash and water vapor that drifted northwest over the Bismarck Sea .
