126-498: Vung Tau port includes the following component ports: According to the approved plan, from now to 2020, two more harbors will be built, one is the Long Son Port serving the oil refinery, the other is Sao Mai-Ben Dinh serving passenger transportation. National Route 51 will connect Cai Mep - Thi Vai Port to Ho Chi Minh City and the manufacturing centres in Đồng Nai Province and Bình Dương Province . However, as of December 2011 it

252-714: A botanical garden , the Norodom Palace , Hotel Continental , Notre-Dame Cathedral , and Bến Thành Market , among many others. In April 1865, Gia Định Báo was established in Saigon, becoming the first newspaper published in Vietnam. During the French colonial era, Saigon became known as "Pearl of the Orient" ( Hòn ngọc Viễn Đông ), or "Paris of the Extreme Orient". On 27 April 1931,

378-482: A centre of resistance against Tây Sơn. Two years later, a large Vauban citadel called Gia Định , or Thành Bát Quái ("Eight Diagrams") was built by Victor Olivier de Puymanel , one of the Nguyễn Ánh's French mercenaries . The citadel was captured by Lê Văn Khôi during his revolt of 1833–35 against Emperor Minh Mạng . Following the revolt, Minh Mạng ordered it to be dismantled, and a new citadel, called Phụng Thành ,

504-426: A common Vietnamese surname ( Hồ , 胡 ) with a given name meaning "enlightened will" (from Sino-Vietnamese , 志 明 ; Chí meaning 'will' or 'spirit', and Minh meaning 'light'), in essence, meaning "light bringer". Nowadays, "Saigon" is still used as a semi-official name for the city, in some cases being used interchangeably with Ho Chi Minh City, partly due to its long history and familiarity. "Prey Nokor City"

630-451: A consistent time period, assessments can attribute contributions to sea level rise and provide early indications of change in trajectory. This helps to inform adaptation plans. The different techniques used to measure changes in sea level do not measure exactly the same level. Tide gauges can only measure relative sea level. Satellites can also measure absolute sea level changes. To get precise measurements for sea level, researchers studying

756-487: A larger role over such timescales. Ice loss from Antarctica is likely to dominate very long-term SLR, especially if the warming exceeds 2 °C (3.6 °F). Continued carbon dioxide emissions from fossil fuel sources could cause additional tens of metres of sea level rise, over the next millennia. Burning of all fossil fuels on Earth is sufficient to melt the entire Antarctic ice sheet, causing about 58 m (190 ft) of sea level rise. Year 2021 IPCC estimates for

882-598: A metropolitan area covering most parts of the southeast region plus Tiền Giang Province and Long An Province under planning, will have an area of 30,000 km (12,000 sq mi) with a population of 20 million inhabitants by 2020. Inhabitants of Ho Chi Minh City are usually known as "Saigonese" in English and "dân Sài Gòn" in Vietnamese. The majority of the population are ethnic Vietnamese ( Kinh ) at about 93.52%. Ho Chi Minh City's largest minority ethnic group are

1008-469: A mission to ask his son-in-law, King Chey Chettha II, to set up tax collection stations in Prey Nokor (Sài Gòn) and Kas Krobei (Bến Nghé). Although this was a deserted jungle area, it was located on the traffic routes between Vietnam, Cambodia, and Siam. The next two important events of this period were the establishment of the barracks and residence of Vice King Ang Non and the establishment of

1134-673: A much longer period. Coverage of tide gauges started mainly in the Northern Hemisphere . Data for the Southern Hemisphere remained scarce up to the 1970s. The longest running sea-level measurements, NAP or Amsterdam Ordnance Datum were established in 1675, in Amsterdam . Record collection is also extensive in Australia . They include measurements by Thomas Lempriere , an amateur meteorologist, beginning in 1837. Lempriere established

1260-506: A name that was retained until the time of the French conquest in the 1860s, when it adopted the name Sài Gòn , francized as Saïgon , although the city was still indicated as 嘉 定 on Vietnamese maps written in chữ Hán until at least 1891. The current name, Ho Chi Minh City, was given after reunification in 1976 to honour Ho Chi Minh . Even today, however, the informal name of Sài Gòn remains in daily speech. However, there

1386-532: A new région called Saigon–Cholon consisting of Saigon and Cholon was formed; the name Cholon was dropped after South Vietnam gained independence from France in 1955. From about 256,000 in 1930, Saigon's population rose to 1.2 million in 1950. In 1949, former Emperor Bảo Đại made Saigon the capital of the State of Vietnam with himself as head of state. In 1954, the Geneva Agreement partitioned Vietnam along

1512-607: A palace at Tân Mỹ (near the present-day Cống Quỳnh–Nguyễn Trãi crossroads). It can be said that Saigon was formed from these three government agencies. In 1679, Lord Nguyễn Phúc Tần allowed a group of Chinese refugees from the Qing dynasty to settle in Mỹ Tho , Biên Hòa and Saigon to seek refuge. In 1698, Nguyễn Hữu Cảnh , a Vietnamese noble, was sent by the Nguyễn rulers of Huế by sea to establish Vietnamese administrative structures in

1638-503: A period of thousands of years. The size of the rise in sea level implies a large contribution from the Antarctic and Greenland ice sheets. Levels of atmospheric carbon dioxide of around 400 parts per million (similar to 2000s) had increased temperature by over 2–3 °C (3.6–5.4 °F) around three million years ago. This temperature increase eventually melted one third of Antarctica's ice sheet, causing sea levels to rise 20 meters above

1764-453: A population of around 10 million in 2023. The city's geography is defined by rivers and canals, of which the largest is Saigon River . As a municipality , Ho Chi Minh City consists of 16 urban districts , five rural districts , and one municipal city (sub-city). As the largest financial centre in Vietnam, Ho Chi Minh City has the highest gross regional domestic product out of all Vietnam provinces and municipalities, contributing around

1890-402: A quarter of the country's total GDP . Ho Chi Minh City's metropolitan area is ASEAN's 6th largest economy , also the biggest outside an ASEAN country capital. Since ancient times, water transport has been heavily used by inhabitants in the area. The area was occupied by Champa from 2nd century AD to around the 19th century, due to Đại Việt 's expansionist policy of Nam tiến . After

2016-572: A range of 28–61 cm (11–24 in). The "moderate" scenario, where CO 2 emissions take a decade or two to peak and its atmospheric concentration does not plateau until the 2070s is called RCP 4.5. Its likely range of sea level rise is 36–71 cm (14–28 in). The highest scenario in RCP8.5 pathway sea level would rise between 52 and 98 cm ( 20 + 1 ⁄ 2 and 38 + 1 ⁄ 2  in). AR6 had equivalents for both scenarios, but it estimated larger sea level rise under both. In AR6,

2142-469: A range with a lower and upper limit to reflect the unknowns. The scenarios in the 2013–2014 Fifth Assessment Report (AR5) were called Representative Concentration Pathways , or RCPs and the scenarios in the IPCC Sixth Assessment Report (AR6) are known as Shared Socioeconomic Pathways , or SSPs. A large difference between the two was the addition of SSP1-1.9 to AR6, which represents meeting

2268-651: A sea-level benchmark on a small cliff on the Isle of the Dead near the Port Arthur convict settlement in 1841. Together with satellite data for the period after 1992, this network established that global mean sea level rose 19.5 cm (7.7 in) between 1870 and 2004 at an average rate of about 1.44 mm/yr. (For the 20th century the average is 1.7 mm/yr.) By 2018, data collected by Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) had shown that

2394-463: A sharp reduction in greenhouse gas emissions, this may increase to hundreds of millions in the latter decades of the century. Local factors like tidal range or land subsidence will greatly affect the severity of impacts. For instance, sea level rise in the United States is likely to be two to three times greater than the global average by the end of the century. Yet, of the 20 countries with

2520-602: A small group of Bawean from Bawean Island in Indonesia (about 400; as of 2015), they occupy District 1. Various other nationalities including Koreans, Japanese, Americans, South Africans, Filipinos and Britons reside in Ho Chi Minh City, particularly in Thủ Đức and District 7 as expatriate workers. As of April 2009, the city recognises 13 religions and 1,983,048 residents identify as religious people. Buddhism and Catholicism are

2646-593: A version of SSP5-8.5 where these processes take place, and in that case, sea level rise of up to 1.6 m ( 5 + 1 ⁄ 3  ft) by 2100 could not be ruled out. The greatest uncertainty with sea level rise projections is associated with the so-called marine ice sheet instability (MISI), and, even more so, Marine Ice Cliff Instability (MICI). These processes are mainly associated with West Antarctic Ice Sheet, but may also apply to some of Greenland's glaciers. The former suggests that when glaciers are mostly underwater on retrograde (backwards-sloping) bedrock,

2772-737: Is 28 °C (82 °F), with little variation throughout the year. The highest temperature recorded was 40.0 °C (104 °F) in April while the lowest temperature recorded was 13.8 °C (57 °F) in January. On average, the city experiences between 2,400 and 2,700 hours of sunshine per year. The city is a municipality at the same level as Vietnam's provinces , which is subdivided into 22 district-level sub-divisions (as of 2020): They are further subdivided into 5 commune-level towns (or townlets), 58 communes, and 249 wards (as of 2020 , see List of HCMC administrative units below). On 1 January 2021, it

2898-573: Is 47 km (29 mi). Due to its location on the Mekong Delta, the city is fringed by tidal flats that have been heavily modified for agriculture. Saigon is considered one of the most vulnerable cities to the effects of climate change , particularly flooding. During the rainy season, a combination of high tide, heavy rains, high flow volume in the Saigon River and Đồng Nai River and land subsidence results in regular flooding in several parts of

3024-515: Is a technical difference between the two terms: Sài Gòn is commonly used to refer to the city centre in District 1 and the adjacent areas, while Ho Chi Minh City refers to all of its urban and rural districts. The original toponym behind Sài Gòn, was attested earliest as 柴棍 , with two phonograms whose Sino-Vietnamese readings are sài and côn respectively, in Lê Quý Đôn's "Miscellaneous Chronicles of

3150-402: Is by lowering the global temperature to 1 °C (1.8 °F) below the preindustrial level. This would be 2 °C (3.6 °F) below the temperature of 2020. Other researchers suggested that a climate engineering intervention to stabilize the ice sheet's glaciers may delay its loss by centuries and give more time to adapt. However this is an uncertain proposal, and would end up as one of

3276-454: Is due to the high level of inertia in the carbon cycle and the climate system, owing to factors such as the slow diffusion of heat into the deep ocean , leading to a longer climate response time. A 2018 paper estimated that sea level rise in 2300 would increase by a median of 20 cm (8 in) for every five years CO 2 emissions increase before peaking. It shows a 5% likelihood of a 1 m ( 3 + 1 ⁄ 2  ft) increase due to

3402-420: Is expected to grow to 13.9 million by 2025. The population of the city is expanding faster than earlier predictions. In August 2017, the city's mayor, Nguyễn Thành Phong, admitted that previous estimates of 8–10 million were drastic underestimations. The actual population (including those who have not officially registered) was estimated 13 million in 2017. The Ho Chi Minh City Metropolitan Area ,

3528-465: Is facing increasing threats of sea level rise and flooding as well as heavy strains on public infrastructures. The first known human habitation in the area was a Cham settlement called Baigaur. The Cambodians then took over the Cham village of Baigaur and renamed it Prey Nokor, a small fishing village. Over time, under the control of the Vietnamese, it was officially renamed Gia Định ( 嘉 定 ) in 1698,

3654-460: Is now unstoppable. However the temperature changes in future, the warming of 2000–2019 had already damaged the ice sheet enough for it to eventually lose ~3.3% of its volume. This is leading to 27 cm ( 10 + 1 ⁄ 2  in) of future sea level rise. At a certain level of global warming, the Greenland ice sheet will almost completely melt. Ice cores show this happened at least once over

3780-474: Is still under construction. As a result, goods still have to be shipped by barge from Ho Chi Minh City to Vung Tau. 10°23′10″N 107°05′06″E  /  10.386°N 107.085°E  / 10.386; 107.085 Ho Chi Minh City Ho Chi Minh City ( HCMC ; Vietnamese : Thành phố Hồ Chí Minh ), better known as Saigon ( Vietnamese : Sài Gòn ), is the most populous city in Vietnam , with

3906-510: Is the East Antarctic Ice Sheet (EAIS). It is 2.2 km thick on average and holds enough ice to raise global sea levels by 53.3 m (174 ft 10 in) Its great thickness and high elevation make it more stable than the other ice sheets. As of the early 2020s, most studies show that it is still gaining mass. Some analyses have suggested it began to lose mass in the 2000s. However they over-extrapolated some observed losses on to

4032-409: Is the fastest it had been over at least the past 3,000 years. While sea level rise is uniform around the globe, some land masses are moving up or down as a consequence of subsidence (land sinking or settling) or post-glacial rebound (land rising as melting ice reduces weight). Therefore, local relative sea level rise may be higher or lower than the global average. Changing ice masses also affect

4158-462: Is the largest and most influential scientific organization on climate change, and since 1990, it provides several plausible scenarios of 21st century sea level rise in each of its major reports. The differences between scenarios are mainly due to uncertainty about future greenhouse gas emissions. These depend on future economic developments, and also future political action which is hard to predict. Each scenario provides an estimate for sea level rise as

4284-581: Is well known in Khmer, whereas "Ho Chi Minh City" is used to refer to the whole city. The earliest settlement in the area was a Funan temple at the location of the current Phụng Sơn Buddhist temple, founded in the 4th century AD. A settlement called Baigaur was established on the site in the 11th century by the Champa . Baigaur was renamed Prey Nokor after conquest by the Khmer Empire around 1145, Prey Nokor grew on

4410-456: The 17th parallel ( Bến Hải River ), with the communist Việt Minh , under Ho Chi Minh , gaining complete control of the northern half of the country , while the southern half gained independence from France. The State officially became the Republic of Vietnam when Bảo Đại was deposed by his Prime Minister Ngô Đình Diệm in the 1955 referendum , with Saigon as its capital. On 22 October 1956,

4536-515: The Amundsen Sea Embayment played a disproportionate role. The median estimated increase in sea level rise from Antarctica by 2100 is ~11 cm (5 in). There is no difference between scenarios, because the increased warming would intensify the water cycle and increase snowfall accumulation over the EAIS at about the same rate as it would increase ice loss from WAIS. However, most of

4662-498: The Earth 's temperature by many decades, and sea level rise will therefore continue to accelerate between now and 2050 in response to warming that has already happened. What happens after that depends on human greenhouse gas emissions . If there are very deep cuts in emissions, sea level rise would slow between 2050 and 2100. It could then reach by 2100 slightly over 30 cm (1 ft) from now and approximately 60 cm (2 ft) from

4788-588: The Pacific Decadal Oscillation (PDO) and the El Niño–Southern Oscillation (ENSO) change from one state to the other. The PDO is a basin-wide climate pattern consisting of two phases, each commonly lasting 10 to 30 years. The ENSO has a shorter period of 2 to 7 years. The global network of tide gauges is the other important source of sea-level observations. Compared to the satellite record, this record has major spatial gaps but covers

4914-696: The Port of Saigon is among the busiest container ports in Southeast Asia . Ho Chi Minh City is also a tourist attraction. Some of the war and historic landmarks in the city include the Independence Palace , Landmark 81 (tallest building in Vietnam), the War Remnants Museum , and Bến Thành Market . The city is also known for its narrow walkable alleys and bustling night life . Currently, Ho Chi Minh City

5040-595: The SROCC assessed several studies attempting to estimate 2300 sea level rise caused by ice loss in Antarctica alone, arriving at projected estimates of 0.07–0.37 metres (0.23–1.21 ft) for the low emission RCP2.6 scenario, and 0.60–2.89 metres (2.0–9.5 ft) in the high emission RCP8.5 scenario. This wide range of estimates is mainly due to the uncertainties regarding marine ice sheet and marine ice cliff instabilities. The world's largest potential source of sea level rise

5166-685: The Vietnamese People's Army . In 1976, upon the establishment of the unified communist Socialist Republic of Vietnam, the city of Saigon (including the Cholon area), the province of Gia Ðịnh and two suburban districts of two other nearby provinces were combined to create Ho Chi Minh City, in honour of the late Communist leader Ho Chi Minh. At the time, the city covered an area of 1,295.5 square kilometres (500.2 sq mi) with eight districts and five rurals: Thủ Đức , Hóc Môn , Củ Chi , Bình Chánh , and Nhà Bè . Since 1978, administrative divisions in

5292-628: The bedrock underlying the WAIS lies well below sea level, and it has to be buttressed by the Thwaites and Pine Island glaciers. If these glaciers were to collapse, the entire ice sheet would as well. Their disappearance would take at least several centuries, but is considered almost inevitable, as their bedrock topography deepens inland and becomes more vulnerable to meltwater, in what is known as marine ice sheet instability. The contribution of these glaciers to global sea levels has already accelerated since

5418-430: The ice shelves propping them up are gone. The collapse then exposes the ice masses following them to the same instability, potentially resulting in a self-sustaining cycle of cliff collapse and rapid ice sheet retreat. This theory had been highly influential - in a 2020 survey of 106 experts, the 2016 paper which suggested 1 m ( 3 + 1 ⁄ 2  ft) or more of sea level rise by 2100 from Antarctica alone,

5544-515: The 1960s, Saigon experienced economic downturn and high inflation, as it was completely dependent on U.S. aid and imports from other countries. As a result of widespread urbanisation, with the population reaching 3.3 million by 1970, the city was described by the USAID as being turned "into a huge slum". The city also suffered from "prostitutes, drug addicts, corrupt officials, beggars, orphans, and Americans with money", and according to Stanley Karnow , it

5670-449: 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 . Sea level rise lags behind changes in

5796-491: The 1990s, the city underwent rapid expansion and modernization, which contributed to Vietnam's post-war economic recovery and helped revive its international trade hub status. Ho Chi Minh City has a long tradition of being one of the centers of economy, entertainment and education in Vietnam. As such, the city is also the busiest international transport hub in Vietnam, as Tân Sơn Nhất International Airport accounts for nearly half of all international arrivals to Vietnam and

5922-973: The 19th century. With high emissions it would instead accelerate further, and could rise by 1.0 m ( 3 + 1 ⁄ 3  ft) or even 1.6 m ( 5 + 1 ⁄ 3  ft) by 2100. In the long run, sea level rise would amount to 2–3 m (7–10 ft) over the next 2000 years if warming stays to its current 1.5 °C (2.7 °F) over the pre-industrial past. It would be 19–22 metres (62–72 ft) if warming peaks at 5 °C (9.0 °F). Rising seas affect every coastal and island population on Earth. This can be through flooding, higher storm surges , king tides , and tsunamis . There are many knock-on effects. They lead to loss of coastal ecosystems like mangroves . Crop yields may reduce because of increasing salt levels in irrigation water. Damage to ports disrupts sea trade. The sea level rise projected by 2050 will expose places currently inhabited by tens of millions of people to annual flooding. Without

6048-573: The Antarctic continent stores around 60% of the world's fresh water. Excluding groundwater this is 90%. Antarctica is experiencing ice loss from coastal glaciers in the West Antarctica and some glaciers of East Antarctica . However it is gaining mass from the increased snow build-up inland, particularly in the East. This leads to contradicting trends. There are different satellite methods for measuring ice mass and change. Combining them helps to reconcile

The Hoa (Chinese) speak a number of varieties of Chinese , including Cantonese , Teochew (Chaozhou), Hokkien , Hainanese , and Hakka ; smaller numbers also speak Mandarin Chinese . Other ethnic minorities include Khmer with 0.34%, Cham with 0.1%, as well as

6426-495: The Earth was 2 °C (3.6 °F) warmer than pre-industrial temperatures was 120,000 years ago. This was when warming due to Milankovitch cycles (changes in the amount of sunlight due to slow changes in the Earth's orbit) caused the Eemian interglacial . Sea levels during that warmer interglacial were at least 5 m (16 ft) higher than now. The Eemian warming was sustained over

6552-438: The Greenland ice sheet between 1992 and 2018 amounted to 3,902 gigatons (Gt) of ice. This is equivalent to a SLR contribution of 10.8 mm. The contribution for the 2012–2016 period was equivalent to 37% of sea level rise from land ice sources (excluding thermal expansion). This observed rate of ice sheet melting is at the higher end of predictions from past IPCC assessment reports. In 2021, AR6 estimated that by 2100,

6678-586: The Last Interglacial SLR is unlikely to have been higher than 2.7 m (9 ft), as higher values in other research, such as 5.7 m ( 18 + 1 ⁄ 2  ft), appear inconsistent with the new paleoclimate data from The Bahamas and the known history of the Greenland Ice Sheet. Even if the temperature stabilizes, significant sea-level rise (SLR) will continue for centuries, consistent with paleo records of sea level rise. This

6930-597: The SSP1-1.9 scenario would result in sea level rise in the 17–83% range of 37–86 cm ( 14 + 1 ⁄ 2 –34 in). In the SSP1-2.6 pathway the range would be 46–99 cm (18–39 in), for SSP2-4.5 a 66–133 cm (26– 52 + 1 ⁄ 2  in) range by 2100 and for SSP5-8.5 a rise of 98–188 cm ( 38 + 1 ⁄ 2 –74 in). It stated that the "low-confidence, high impact" projected 0.63–1.60 m (2–5 ft) mean sea level rise by 2100, and that by 2150,

7056-519: The SSP1-2.6 pathway results in a range of 32–62 cm ( 12 + 1 ⁄ 2 – 24 + 1 ⁄ 2  in) by 2100. The "moderate" SSP2-4.5 results in a 44–76 cm ( 17 + 1 ⁄ 2 –30 in) range by 2100 and SSP5-8.5 led to 65–101 cm ( 25 + 1 ⁄ 2 –40 in). This general increase of projections in AR6 came after the improvements in ice-sheet modeling and the incorporation of structured expert judgements. These decisions came as

7182-523: The Vietnamese source Phủ biên tạp lục (albeit written in literary Chinese) was the earliest extant one containing the local toponym's transcription; (2) 堤岸 has variant form 提岸 , thus suggesting that both were transcriptions of a local toponym and thus are cognates to, not originals of, Sài Gòn. Saigon is unlikely to be from 堤岸 since in "Textbook on the Geography of the Southern Country", it also lists Chợ Lớn as 𢄂𢀲 separate from 柴棍 Sài Gòn.

Ice cliff instability would cause a contribution of 1 m ( 3 + 1 ⁄ 2  ft) or more if it were applicable. The melting of all the ice in West Antarctica would increase the total sea level rise to 4.3 m (14 ft 1 in). However, mountain ice caps not in contact with water are less vulnerable than

7434-444: The amount of sea level rise over the next 2,000 years project that: Sea levels would continue to rise for several thousand years after the ceasing of emissions, due to the slow nature of climate response to heat. The same estimates on a timescale of 10,000 years project that: Variations in the amount of water in the oceans, changes in its volume, or varying land elevation compared to the sea surface can drive sea level changes.

7686-422: The average world ocean temperature by 0.01 °C (0.018 °F) would increase atmospheric temperature by approximately 10 °C (18 °F). So a small change in the mean temperature of the ocean represents a very large change in the total heat content of the climate system. Winds and currents move heat into deeper parts of the ocean.

7938-485: The best-case scenario, ice sheet under SSP1-2.6 gains enough mass by 2100 through surface mass balance feedbacks to reduce the sea levels by 2 cm (1 in). In the worst case, it adds 15 cm (6 in). For SSP5-8.5, the best-case scenario is adding 5 cm (2 in) to sea levels, and the worst-case is adding 23 cm (9 in). Greenland's peripheral glaciers and ice caps crossed an irreversible tipping point around 1997. Sea level rise from their loss

8064-407: The city centre and 16 m (52 ft) for the suburb areas. It borders Tây Ninh Province and Bình Dương Province to the north, Đồng Nai Province and Bà Rịa–Vũng Tàu province to the east, Long An Province to the west, Tiền Giang Province and South China Sea to the south with a coast 15 km (9 mi) long. The city covers an area of 2,095 km (809 sq mi) or 0.63% of

8190-403: The city had 4,344,000 labourers, of whom 130,000 are over the labour age norm (in Vietnam, 60 for male and 55 for female workers). In 2009, GDP per capita reached $ 2,800, compared to the country's average level of $ 1,042. Sea level rise 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

8316-535: The city have been revised numerous times, most recently in 2020, when District 2 , District 9 , and Thủ Đức District were consolidated to form a municipal city . On 29 October 2002, 60 people died and 90 injured in the International Trade Center building fire in Ho Chi Minh City. Today, Ho Chi Minh City, along with its surrounding provinces, is described as "the manufacturing hub" of Vietnam, and "an attractive business hub". In terms of cost, it

8442-514: The city is the Ho Chi Minh City People's Council and consists of 105 members. The current chairwoman is Nguyễn Thị Lệ . The judiciary branch of the city is the Ho Chi Minh City People's Court. The current chief judge is Lê Thanh Phong . The executive committee of Communist Party of Ho Chi Minh City is the leading organ of the Communist Party in Ho Chi Minh City. The current secretary is Nguyễn Văn Nên . The permanent deputy secretary of

8568-409: The city was given the official name, Đô Thành Sài Gòn ("Capital City Saigon"). After the decree of 27 March 1959 came into effect, Saigon was divided into eight districts and 41 wards. In December 1966, two wards from old An Khánh Commune of Gia Định, were formed into District 1, then seceded shortly later to become District 9. In July 1969, District 10 and District 11 were founded, and by 1975,

8694-563: The city's area consisted of eleven districts, Gia Định , Củ Chi District ( Hậu Nghĩa ), and Phú Hòa District ( Bình Dương ). Saigon served as the financial, industrial and transport centre of the Republic of Vietnam. In the late 1950s, with the U.S. providing nearly $ 2 billion in aid to the Diệm regime, the country's economy grew rapidly under capitalism ; by 1960, over half of South Vietnam's factories were located in Saigon. However, beginning in

8820-435: The city, as of the 1 October 2004 census, was 6,117,251 (of which 19 inner districts had 5,140,412 residents and 5 suburban districts had 976,839 inhabitants). In mid-2007, the city's population was 6,650,942 – with the 19 inner districts home to 5,564,975 residents and the five suburban districts containing 1,085,967 inhabitants. The result of the 2009 Census shows that the city's population was 7,162,864 people, about 8.34% of

8946-463: The city, in protest of the Diệm regime. On 1 November of the same year, Diệm was assassinated in Saigon, in a successful coup by Dương Văn Minh . During the 1968 Tet Offensive , communist forces launched a failed attempt to capture the city . Seven years later, on 30 April 1975, Saigon was captured , ending the Vietnam War with a victory for North Vietnam, and the city came under the control of

9072-479: The city. A once-in-100 year flood would cause 23% of the city to suffer flooding. The city has a tropical climate , specifically tropical savanna ( Aw ), with a high average humidity of 78–82%. The year is divided into two distinct seasons. The rainy season, with an average rainfall of about 1,800 mm (71 in) annually (about 150 rainy days per year), usually lasts from May to November. The dry season lasts from December to April. The average temperature

9198-459: The contribution from these is thought to be small. Glacier retreat and ocean expansion have dominated sea level rise since the start of the 20th century. Some of the losses from glaciers are offset when precipitation falls as snow, accumulates and over time forms glacial ice. If precipitation, surface processes and ice loss at the edge balance each other, sea level remains the same. Because of this precipitation began as water vapor evaporated from

9324-517: The differences. However, there can still be variations between the studies. In 2018, a systematic review estimated average annual ice loss of 43 billion tons (Gt) across the entire continent between 1992 and 2002. This tripled to an annual average of 220 Gt from 2012 to 2017. However, a 2021 analysis of data from four different research satellite systems ( Envisat , European Remote-Sensing Satellite , GRACE and GRACE-FO and ICESat ) indicated annual mass loss of only about 12 Gt from 2012 to 2016. This

9450-456: The distribution of sea water around the globe through gravity. Several approaches are used for sea level rise (SLR) projections. One is process-based modeling, where ice melting is computed through an ice-sheet model and rising sea temperature and expansion through a general circulation model , and then these contributions are added up. The so-called semi-empirical approach instead applies statistical techniques and basic physical modeling to

9576-428: The empirical 2.5 °C (4.5 °F) upper limit from ice cores. If temperatures reach or exceed that level, reducing the global temperature to 1.5 °C (2.7 °F) above pre-industrial levels or lower would prevent the loss of the entire ice sheet. One way to do this in theory would be large-scale carbon dioxide removal , but there would still be cause of greater ice losses and sea level rise from Greenland than if

9702-403: The extremely low probability of large climate change-induced increases in precipitation greatly elevating ice sheet surface mass balance .) In 2020, 106 experts who contributed to 6 or more papers on sea level estimated median 118 cm ( 46 + 1 ⁄ 2  in) SLR in the year 2300 for the low-warming RCP2.6 scenario and the median of 329 cm ( 129 + 1 ⁄ 2  in) for

9828-472: The fall of the Citadel of Saigon , the city became the capital of French Indochina from 1887 to 1902, and again from 1945 until its cessation in 1954. Following the partition of French Indochina , it became the capital of South Vietnam until it was captured by North Vietnam , who renamed the city after their former leader Hồ Chí Minh , though the former name is still widely used in informal usages. Beginning in

9954-559: The global mean sea level was rising by 3.2 mm ( 1 ⁄ 8  in) per year. This was double the average 20th century rate. The 2023 World Meteorological Organization report found further acceleration to 4.62 mm/yr over the 2013–2022 period. These observations help to check and verify predictions from climate change simulations. Regional differences are also visible in the tide gauge data. Some are caused by local sea level differences. Others are due to vertical land movements. In Europe , only some land areas are rising while

10080-1024: The greatest exposure to sea level rise, twelve are in Asia , including Indonesia , Bangladesh and the Philippines. The resilience and adaptive capacity of ecosystems and countries also varies, which will result in more or less pronounced impacts. The greatest impact on human populations in the near term will occur in the low-lying Caribbean and Pacific islands . Sea level rise will make many of them uninhabitable later this century. Societies can adapt to sea level rise in multiple ways. Managed retreat , accommodating coastal change , or protecting against sea level rise through hard-construction practices like seawalls are hard approaches. There are also soft approaches such as dune rehabilitation and beach nourishment . Sometimes these adaptation strategies go hand in hand. At other times choices must be made among different strategies. Poorer nations may also struggle to implement

10206-536: The high-warming RCP8.5. The former scenario had the 5%–95% confidence range of 24–311 cm ( 9 + 1 ⁄ 2 – 122 + 1 ⁄ 2  in), and the latter of 88–783 cm ( 34 + 1 ⁄ 2 – 308 + 1 ⁄ 2  in). After 500 years, sea level rise from thermal expansion alone may have reached only half of its eventual level - likely within ranges of 0.5–2 m ( 1 + 1 ⁄ 2 – 6 + 1 ⁄ 2  ft). Additionally, tipping points of Greenland and Antarctica ice sheets are likely to play

10332-417: The hypothesis after 2016 often suggested that the ice shelves in the real world may collapse too slowly to make this scenario relevant, or that ice mélange - debris produced as the glacier breaks down - would quickly build up in front of the glacier and significantly slow or even outright stop the instability soon after it began. Due to these uncertainties, some scientists - including the originators of

10458-532: The hypothesis, Robert DeConto and David Pollard - have suggested that the best way to resolve the question would be to precisely determine sea level rise during the Last Interglacial . MICI can be effectively ruled out if SLR at the time was lower than 4 m (13 ft), while it is very likely if the SLR was greater than 6 m ( 19 + 1 ⁄ 2  ft). As of 2023, the most recent analysis indicates that

10584-415: The ice and oceans factor in ongoing deformations of the solid Earth . They look in particular at landmasses still rising from past ice masses retreating , and the Earth's gravity and rotation . Since the launch of TOPEX/Poseidon in 1992, an overlapping series of altimetric satellites has been continuously recording the sea level and its changes. These satellites can measure the hills and valleys in

10710-408: The ice on Earth would result in about 70 m (229 ft 8 in) of sea level rise, although this would require at least 10,000 years and up to 10 °C (18 °F) of global warming. The oceans store more than 90% of the extra heat added to the climate system by Earth's energy imbalance and act as a buffer against its effects. This means that the same amount of heat that would increase

10836-719: The largest potential source of sea level rise. However the West Antarctic ice sheet (WAIS) is substantially more vulnerable. Temperatures on West Antarctica have increased significantly, unlike East Antarctica and the Antarctic Peninsula . The trend is between 0.08 °C (0.14 °F) and 0.96 °C (1.73 °F) per decade between 1976 and 2012. Satellite observations recorded a substantial increase in WAIS melting from 1992 to 2017. This resulted in 7.6 ± 3.9 mm ( 19 ⁄ 64  ±  5 ⁄ 32  in) of Antarctica sea level rise. Outflow glaciers in

10962-414: The last million years, during which the temperatures have at most been 2.5 °C (4.5 °F) warmer than the preindustrial average. 2012 modelling suggested that the tipping point of the ice sheet was between 0.8 °C (1.4 °F) and 3.2 °C (5.8 °F). 2023 modelling has narrowed the tipping threshold to a 1.7 °C (3.1 °F)-2.3 °C (4.1 °F) range, which is consistent with

11088-469: The main Cambodian army at Bích Đôi citadel, king Chey Chettha IV took flight while his nephew Ang Em surrendered to the invaders, as the Vietnamese marched onto and captured Cambodia's capital Phnom Penh . As a result, Saigon and Long An were officially and securely obtained by the Nguyễn, more Vietnamese settlers moved into the new conquered lands. In 1788, Nguyễn Ánh captured the city, and used it as

11214-426: The majority of the ice sheet, which is located below the sea level. Its collapse would cause ~3.3 m (10 ft 10 in) of sea level rise. This disappearance would take an estimated 2000 years. The absolute minimum for the loss of West Antarctica ice is 500 years, and the potential maximum is 13,000 years. Once ice loss from the West Antarctica is triggered, the only way to restore it to near-present values

11340-500: The melting of Greenland ice sheet would most likely add around 6 cm ( 2 + 1 ⁄ 2  in) to sea levels under the low-emission scenario, and 13 cm (5 in) under the high-emission scenario. The first scenario, SSP1-2.6 , largely fulfils the Paris Agreement goals, while the other, SSP5-8.5, has the emissions accelerate throughout the century. The uncertainty about ice sheet dynamics can affect both pathways. In

11466-563: The most expensive projects ever attempted. Most ice on Greenland is in the Greenland ice sheet which is 3 km (10,000 ft) at its thickest. The rest of Greenland ice forms isolated glaciers and ice caps. The average annual ice loss in Greenland more than doubled in the early 21st century compared to the 20th century. Its contribution to sea level rise correspondingly increased from 0.07 mm per year between 1992 and 1997 to 0.68 mm per year between 2012 and 2017. Total ice loss from

11592-628: The observed ice-sheet erosion in Greenland and Antarctica had matched the upper-end range of the AR5 projections by 2020, and the finding that AR5 projections were likely too slow next to an extrapolation of observed sea level rise trends, while the subsequent reports had improved in this regard. Further, AR5 was criticized by multiple researchers for excluding detailed estimates the impact of "low-confidence" processes like marine ice sheet and marine ice cliff instability, which can substantially accelerate ice loss to potentially add "tens of centimeters" to sea level rise within this century. AR6 includes

11718-496: The observed sea level rise and its reconstructions from the historical geological data (known as paleoclimate modeling). It was developed because process-based model projections in the past IPCC reports (such as the Fourth Assessment Report from 2007) were found to underestimate the already observed sea level rise. By 2013, improvements in modeling had addressed this issue, and model and semi-empirical projections for

11844-473: The ocean gains heat, the water expands and sea level rises. Warmer water and water under great pressure (due to depth) expand more than cooler water and water under less pressure. Consequently, cold Arctic Ocean water will expand less than warm tropical water. Different climate models present slightly different patterns of ocean heating. So their projections do not agree fully on how much ocean heating contributes to sea level rise. The large volume of ice on

11970-543: The ocean surface, effects of climate change on the water cycle can even increase ice build-up. However, this effect is not enough to fully offset ice losses, and sea level rise continues to accelerate. The contributions of the two large ice sheets, in Greenland and Antarctica , are likely to increase in the 21st century. They store most of the land ice (~99.5%) and have a sea-level equivalent (SLE) of 7.4 m (24 ft 3 in) for Greenland and 58.3 m (191 ft 3 in) for Antarctica. Thus, melting of all

12096-401: The other hand, the whole EAIS would not definitely collapse until global warming reaches 7.5 °C (13.5 °F), with a range between 5 °C (9.0 °F) and 10 °C (18 °F). It would take at least 10,000 years to disappear. Some scientists have estimated that warming would have to reach at least 6 °C (11 °F) to melt two thirds of its volume. East Antarctica contains

12222-454: The others are sinking. Since 1970, most tidal stations have measured higher seas. However sea levels along the northern Baltic Sea have dropped due to post-glacial rebound . An understanding of past sea level is an important guide to where current changes in sea level will end up. In the recent geological past, thermal expansion from increased temperatures and changes in land ice are the dominant reasons of sea level rise. The last time that

12348-476: The people of the two countries could freely move back and forth. In exchange, Chey Chettha II gifted Prei Nokor to the Nguyễn lords . Vietnamese settlers began to migrate to the area of Saigon, Đồng Nai. Before that, the Funanese, Khmer, and Cham had lived there, scattered from time immemorial. The period from 1623 to 1698 is considered the period of the formation of later Saigon. In 1623, Lord Nguyen sent

12474-641: The poorly observed areas. A more complete observational record shows continued mass gain. In spite of the net mass gain, some East Antarctica glaciers have lost ice in recent decades due to ocean warming and declining structural support from the local sea ice , such as Denman Glacier , and Totten Glacier . Totten Glacier is particularly important because it stabilizes the Aurora Subglacial Basin . Subglacial basins like Aurora and Wilkes Basin are major ice reservoirs together holding as much ice as all of West Antarctica. They are more vulnerable than

12600-547: The preindustrial levels. Since the Last Glacial Maximum , about 20,000 years ago, sea level has risen by more than 125 metres (410 ft). Rates vary from less than 1 mm/year during the pre-industrial era to 40+ mm/year when major ice sheets over Canada and Eurasia melted. Meltwater pulses are periods of fast sea level rise caused by the rapid disintegration of these ice sheets. The rate of sea level rise started to slow down about 8,200 years before today. Sea level

12726-507: The projected range for total sea level rise was 9.5–16.2 metres (31–53 ft) by the year 2300. Projections for subsequent years are more difficult. In 2019, when 22 experts on ice sheets were asked to estimate 2200 and 2300 SLR under the 5   °C warming scenario, there were 90% confidence intervals of −10 cm (4 in) to 740 cm ( 24 + 1 ⁄ 2  ft) and − 9 cm ( 3 + 1 ⁄ 2  in) to 970 cm (32 ft), respectively. (Negative values represent

12852-549: The rest are the Saigonese who don't believe in God which is Atheism . The city is the economic center of Vietnam and accounts for a large proportion of the economy of Vietnam . Although the city takes up just 0.6% of the country's land area, it contains 8.34% of the population of Vietnam, 20.2% of its GDP, 27.9% of industrial output and 34.9% of the FDI projects in the country in 2005. In 2005,

12978-563: The rest of East Antarctica. Their collective tipping point probably lies at around 3 °C (5.4 °F) of global warming. It may be as high as 6 °C (11 °F) or as low as 2 °C (3.6 °F). Once this tipping point is crossed, the collapse of these subglacial basins could take place over as little as 500 or as much as 10,000 years. The median timeline is 2000 years. Depending on how many subglacial basins are vulnerable, this causes sea level rise of between 1.4 m (4 ft 7 in) and 6.4 m (21 ft 0 in). On

13104-458: The same approaches to adapt to sea level rise as richer states. Between 1901 and 2018, the global mean sea level rose by about 20 cm (7.9 in). More precise data gathered from satellite radar measurements found an increase of 7.5 cm (3.0 in) from 1993 to 2017 (average of 2.9 mm (0.11 in)/yr). This accelerated to 4.62 mm (0.182 in)/yr for 2013–2022. Paleoclimate data shows that this rate of sea level rise

13230-426: The same. The same estimate found that if the temperature stabilized below 2 °C (3.6 °F), 2300 sea level rise would still exceed 1.5 m (5 ft). Early net zero and slowly falling temperatures could limit it to 70–120 cm ( 27 + 1 ⁄ 2 –47 in). By 2021, the IPCC Sixth Assessment Report was able to provide estimates for sea level rise in 2150. Keeping warming to 1.5   °C under

13356-404: The sea caused by currents and detect trends in their height. To measure the distance to the sea surface, the satellites send a microwave pulse towards Earth and record the time it takes to return after reflecting off the ocean's surface. Microwave radiometers correct the additional delay caused by water vapor in the atmosphere . Combining these data with the location of the spacecraft determines

13482-476: The sea-surface height to within a few centimetres. These satellite measurements have estimated rates of sea level rise for 1993–2017 at 3.0 ± 0.4 millimetres ( 1 ⁄ 8  ±  1 ⁄ 64  in) per year. Satellites are useful for measuring regional variations in sea level. An example is the substantial rise between 1993 and 2012 in the western tropical Pacific. This sharp rise has been linked to increasing trade winds . These occur when

13608-522: The site of a small fishing village and area of forest. The first Vietnamese people crossed the sea to explore this land completely without the organisation of the Nguyễn Lords . Thanks to the marriage between Princess Nguyễn Phúc Ngọc Vạn - daughter of Lord Nguyễn Phúc Nguyên - and the King of Cambodia  Chey Chettha II in 1620, the relationship between Vietnam and Cambodia became smooth, and

13734-673: The specific regions. A structured expert judgement may be used in combination with modeling to determine which outcomes are more or less likely, which is known as "shifted SEJ". Semi-empirical techniques can be combined with the so-called "intermediate-complexity" models. After 2016, some ice sheet modeling exhibited the so-called ice cliff instability in Antarctica, which results in substantially faster disintegration and retreat than otherwise simulated. The differences are limited with low warming, but at higher warming levels, ice cliff instability predicts far greater sea level rise than any other approach. The Intergovernmental Panel on Climate Change

13860-509: The surface of Vietnam), extending up to Củ Chi District (12 mi or 19 km from the Cambodian border) and down to Cần Giờ on the Eastern Sea. The distance from the northernmost point (Phú Mỹ Hưng Commune, Củ Chi District ) to the southernmost one (Long Hòa Commune, Cần Giờ District) is 102 km (63 mi), and from the easternmost point ( Long Bình ward , District Nine) to the westernmost one (Bình Chánh Commune, Bình Chánh District)

13986-524: The toponyms: provincia Rai-gon, Rai-gon thong (for *Sài Gòn thượng "Upper Saigon"), & Rai-gon-ha (for *Sài Gòn hạ "Lower Saigon"). It is probably a transcription of Khmer ព្រៃនគរ (Prey Nokôr) , or Khmer ព្រៃគរ (Prey Kôr). The proposal that Sài Gòn is from non-Sino-Vietnamese reading of Chinese 堤岸 (“embankment”, tai4 ngon6 , SV: đê ngạn) , the Cantonese name of Chợ Lớn , (e.g. by Vương Hồng Sển) has been critiqued as folk-etymological, as: (1)

14112-492: The total population of Vietnam, making it the highest population-concentrated city in the country. As of the end of 2012, the total population of the city was 7,750,900 people, an increase of 3.1% from 2011. As an administrative unit, its population is also the largest at the provincial level. According to the 2019 census, Ho Chi Minh City has a population of over 8.9 million within the city proper and over 21 million within its metropolitan area . The city's population

14238-453: The total sea level rise in his scenario would be in the range of 0.98–4.82 m (3–16 ft) by 2150. AR6 also provided lower-confidence estimates for year 2300 sea level rise under SSP1-2.6 and SSP5-8.5 with various impact assumptions. In the best case scenario, under SSP1-2.6 with no ice sheet acceleration after 2100, the estimate was only 0.8–2.0 metres (2.6–6.6 ft). In the worst estimated scenario, SSP-8.5 with ice cliff instability,

14364-565: The two predominant religions in Ho Chi Minh City. The largest is Buddhism as it has 1,164,930 followers followed by Catholicism with 745,283 followers, Caodaism with 31,633 followers, Protestantism with 27,016 followers, Islam with 6,580 followers, Hòa Hảo with 4,894 followers, Tịnh độ cư sĩ Phật hội Việt Nam with 1,387 followers, Hinduism with 395 followers, Đạo Tứ ấn hiếu nghĩa with 298 followers, Minh Sư Đạo with 283 followers, Baháʼí Faith with 192 followers, Bửu Sơn Kỳ Hương with 89 followers, Minh Lý Đạo with 67 followers, and

14490-445: The water melts more and more of their height as their retreat continues, thus accelerating their breakdown on its own. This is widely accepted, but is difficult to model. The latter posits that coastal ice cliffs which exceed ~ 90 m ( 295 + 1 ⁄ 2  ft) in above-ground height and are ~ 800 m ( 2,624 + 1 ⁄ 2  ft) in basal (underground) height are likely to rapidly collapse under their own weight once

14616-548: The year 2000. The Thwaites Glacier now accounts for 4% of global sea level rise. It could start to lose even more ice if the Thwaites Ice Shelf fails and would no longer stabilize it, which could potentially occur in mid-2020s. A combination of ice sheet instability with other important but hard-to-model processes like hydrofracturing (meltwater collects atop the ice sheet, pools into fractures and forces them open) or smaller-scale changes in ocean circulation could cause

14742-594: The year 2100 are now very similar. Yet, semi-empirical estimates are reliant on the quality of available observations and struggle to represent non-linearities, while processes without enough available information about them cannot be modeled. Thus, another approach is to combine the opinions of a large number of scientists in what is known as a structured expert judgement (SEJ). Variations of these primary approaches exist. For instance, large climate models are always in demand, so less complex models are often used in their place for simpler tasks like projecting flood risk in

14868-593: Was "a black-market city in the largest sense of the word". On 28 April 1955, the Vietnamese National Army launched an attack against Bình Xuyên military force in the city. The battle lasted until May, killing an estimated 500 people and leaving about 20,000 homeless. Ngô Đình Diệm then later turned on other paramilitary groups in Saigon, including the Hòa Hảo Buddhist reform movement. On 11 June 1963, Buddhist monk Thích Quảng Đức burned himself in

14994-450: Was almost constant for the last 2,500 years. The recent trend of rising sea level started at the end of the 19th or beginning of the 20th century. The three main reasons why global warming causes sea levels to rise are the expansion of oceans due to heating , water inflow from melting ice sheets and water inflow from glaciers. Other factors affecting sea level rise include changes in snow mass, and flow from terrestrial water storage, though

15120-491: Was announced that District 2 , District 9 and Thủ Đức District would be consolidated and was approved by Standing Committee of the National Assembly . The Ho Chi Minh City People's Committee is a 13-member executive branch of the city. The current chairman is Phan Văn Mãi . There are several vice chairmen and chairwomen on the committee with responsibility over various city departments. The legislative branch of

15246-480: Was built in 1836. In 1859, the citadel was destroyed by the French following the Battle of Kỳ Hòa . Initially called Gia Định, the Vietnamese city became Saigon in the 18th century. Ceded to France by the 1862 Treaty of Saigon , the city was planned by the French to transform into a large town for colonization. During the late 19th and early 20th centuries, construction of various French-style buildings began, including

15372-407: Was considered even more important than the 2014 IPCC Fifth Assessment Report . Even more rapid sea level rise was proposed in a 2016 study led by Jim Hansen , which hypothesized multi-meter sea level rise in 50–100 years as a plausible outcome of high emissions, but it remains a minority view amongst the scientific community. Marine ice cliff instability had also been very controversial, since it

15498-502: Was due to greater ice gain in East Antarctica than estimated earlier. In the future, it is known that West Antarctica at least will continue to lose mass, and the likely future losses of sea ice and ice shelves , which block warmer currents from direct contact with the ice sheet, can accelerate declines even in East Antarctica. Altogether, Antarctica is the source of the largest uncertainty for future sea level projections. In 2019,

15624-430: Was first proclaimed in 1945, and later adopted in 1976. It is abbreviated as TP.HCM, and translated in English as Ho Chi Minh City , abbreviated as HCMC, and in French as Hô-Chi-Minh-Ville (the circumflex is sometimes omitted), abbreviated as HCMV. The name commemorates Ho Chi Minh , the first leader of North Vietnam . This name, though not his given name, was one he favored throughout his later years. It combines

15750-465: Was proposed as a modelling exercise, and the observational evidence from both the past and the present is very limited and ambiguous. So far, only one episode of seabed gouging by ice from the Younger Dryas period appears truly consistent with this theory, but it had lasted for an estimated 900 years, so it is unclear if it supports rapid sea level rise in the present. Modelling which investigated

15876-487: Was ranked the 111th-most expensive major city in the world according to a 2020 survey of 209 cities. In terms of international connectedness, as of 2020, the city was classified as a "Beta" city by the Globalization and World Cities Research Network . The city is located in the south-eastern region of Vietnam, 1,760 km (1,090 mi) south of Hanoi . The average elevation is 5 m (16 ft) above sea level for
