112-952: The Last Interglacial is known as the Eemian in northern Europe (sometimes used to describe the global interglacial), Ipswichian in Britain, the Mikulino (also spelled Milukin) interglacial in Russia, the Kaydaky in Ukraine, the Valdivia interglacial in Chile , and the Riss-Würm interglacial in the Alps . Depending on how a specific publication defines the Sangamonian Stage of North America,

224-449: A free market economy that saw an increase in domestic and foreign private investment, although the copper industry and other important mineral resources were not opened to competition. In a plebiscite on 5 October 1988, Pinochet was denied a second eight-year term as president (56% against 44%). Chileans elected a new president and the majority of members of a bicameral congress on 14 December 1989. Christian Democrat Patricio Aylwin ,

336-645: A national referendum in April 2020 regarding the creation of a new Constitution, later postponed to October due to the COVID-19 pandemic . On 25 October 2020, Chileans voted 78.28 per cent in favor of a new constitution, while 21.72 per cent rejected the change. Voter turnout was 51 percent. An election for the members of the Constitutional Convention was held in Chile between 15 and 16 May 2021. On 19 December 2021,

448-578: A parliamentary style democracy. However, the Civil War had also been a contest between those who favored the development of local industries and powerful Chilean banking interests, particularly the House of Edwards which had strong ties to foreign investors. Soon after, the country engaged in a vastly expensive naval arms race with Argentina that nearly led to war, as well because of the Puna de Atacama dispute . After

560-558: A plurality of votes in a three-way contest, followed by candidates Radomiro Tomic for the Christian Democrat Party and Jorge Alessandri for the Conservative Party. Allende was not elected with an absolute majority, receiving fewer than 35% of the votes. The Chilean Congress conducted a runoff vote between the leading candidates, Allende and former president Jorge Alessandri, and, keeping with tradition, chose Allende by

672-614: A campaign of domestic political and economical destabilization, some of which was backed by the United States. By early 1973, inflation was out of control. On 26 May 1973, Chile's Supreme Court, which was opposed to Allende's government, unanimously denounced Allende's disruption of the legality of the nation . Although illegal under the Chilean constitution, the court supported and strengthened Pinochet's soon-to-be seizure of power. A military coup overthrew Allende on 11 September 1973. As

784-510: A diameter of 74 mm from the top 10 m of the ice cap. The shallow drill can take cores up to 50 m long and 74mm in diameter from the top 350 m of ice, and it does not require drilling fluid. The deep drill works in liquid-filled holes, can retrieve the core, and can be operated at any depth. Compared to other drills, the operation is relatively slow. In addition to GRIP, there have been several other ice core projects in Greenland, such as

896-469: A large variety of climates and landscapes. It contains 756,950 square kilometers (292,260 sq mi) of land area. It is situated within the Pacific Ring of Fire . Excluding its Pacific islands and Antarctic claim, Chile lies between latitudes 17° and 56°S , and longitudes 66° and 75°W . Chile is among the longest north–south countries in the world. If one considers only mainland territory, Chile

1008-414: A leftist candidate, the 35-year-old former student protest leader Gabriel Boric , won Chile's presidential election to become the country's youngest ever leader. On 11 March 2022, Boric was sworn in as president to succeed outgoing President Sebastian Piñera. Out of 24 members of Gabriel Boric's female-majority Cabinet, 14 are women. On 4 September 2022, voters rejected the new constitution proposal in

1120-572: A letter dated 12 November 1821, expressing his plan to conquer Guayaquil , the Galapagos Islands , and the Philippines . There were preparations, but the plan did not push through because O'Higgins was exiled. Chile slowly started to expand its influence and to establish its borders. By the Tantauco Treaty, the archipelago of Chiloé was incorporated in 1826. The economy began to boom due to

1232-540: A period of almost 24 hours, an effort that was carried on live television around the world. 2019–20 Chilean protests are a series of country-wide protests in response to a rise in the Santiago Metro 's subway fare, the increased cost of living , privatization and inequality prevalent in the country. On 15 November, most of the political parties represented in the National Congress signed an agreement to call

1344-527: A period of major reform. Under the slogan "Revolution in Liberty", the Frei administration embarked on far-reaching social and economic programs, particularly in education, housing, and agrarian reform , including rural unionization of agricultural workers. By 1967, however, Frei encountered increasing opposition from leftists, who charged that his reforms were inadequate, and from conservatives, who found them excessive. At

1456-694: A prolonged struggle, including infighting from Bernardo O'Higgins , who challenged Carrera's leadership. Intermittent warfare continued until 1817. With Carrera in prison in Argentina, O'Higgins and anti-Carrera cohort José de San Martín , hero of the Argentine War of Independence , led an army that crossed the Andes into Chile and defeated the royalists. On 12 February 1818, Chile was proclaimed an independent republic . The political revolt brought little social change, however, and 19th-century Chilean society preserved

1568-490: A reformist president, Arturo Alessandri , whose program was frustrated by a conservative congress. In the 1920s, Marxist groups with strong popular support arose. A military coup led by General Luis Altamirano in 1924 set off a period of political instability that lasted until 1932. Of the ten governments that held power in that period, the longest lasting was that of General Carlos Ibáñez del Campo , who briefly held power in 1925 and then again between 1927 and 1931 in what

1680-610: A result of mixing of Last Interglacial ice with ice from the preceding or succeeding glacial intervals. The warmest peak of the Last Interglacial was around 125,000 years ago, when forests reached as far north as North Cape, Norway (which is now tundra ) well above the Arctic Circle at 71°10′21″N 25°47′40″E  /  71.17250°N 25.79444°E  / 71.17250; 25.79444 . Hardwood trees such as hazel and oak grew as far north as Oulu , Finland. At

1792-465: A result, ice cores capable of continuous flow analysis have been acquired even from fragile depth zones, and it is expected that more detailed and accurate analysis of gas and other chemicals will be possible in the future. The GRIP logistics were managed by what is now called Centre for Ice and Climate at the Niels Bohr Institute, University of Copenhagen, Denmark. This research centre maintains

1904-731: A vote of 153 to 35. Frei refused to form an alliance with Alessandri to oppose Allende, on the grounds that the Christian Democrats were a workers' party and could not make common cause with the right wing. An economic depression that began in 1972 was exacerbated by capital flight , plummeting private investment, and withdrawal of bank deposits in response to Allende's socialist program. Production fell and unemployment rose. Allende adopted measures including price freezes, wage increases, and tax reforms, to increase consumer spending and redistribute income downward. Joint public-private public works projects helped reduce unemployment. Much of

2016-458: Is also the historical center from which Chile expanded in the late 19th century when it integrated the northern and southern regions. Southern Chile is rich in forests, grazing lands, and features a string of volcanoes and lakes. The southern coast is a labyrinth of fjords, inlets, canals, twisting peninsulas, and islands. The Andes Mountains are located on the eastern border. Greenland ice core project The Greenland Ice Core Project (GRIP)

2128-522: Is as small as possible. In contrast, the latest EastGRIP research was conducted upstream of the Northeast Greenland Ice Stream. This is the most significant active ice stream in Greenland. In addition, the ice depths in the earlier Greenland ice cores that corresponded to the warm period of the early Holocene were very fragile. It was almost impossible to collect highly accurate chemical and gas analysis data with high time resolution from

2240-507: Is given by Lorié (1887), and Spaink (1958). Since their discovery, Last Interglacial beds in the Netherlands have mainly been recognized by their marine molluscan content combined with their stratigraphical position and other palaeontology. The marine beds there are often underlain by tills that are considered to date from the Saalian , and overlain by local fresh water or wind-blown deposits from

2352-575: Is located. Harting noticed the marine molluscan assemblages to be very different from the modern fauna of the North Sea . Many species from the Last Interglacial layers nowadays show a much more southern distribution, ranging from South of the Strait of Dover to Portugal ( Lusitanian faunal province) and even into the Mediterranean (Mediterranean faunal province). More information on the molluscan assemblages

2464-430: Is now Chile. The next Europeans to reach Chile were Diego de Almagro and his band of Spanish conquistadors , who came from Peru in 1535 seeking gold. The Spanish encountered various cultures that supported themselves principally through slash-and-burn agriculture and hunting. The conquest of Chile began in earnest in 1540 and was carried out by Pedro de Valdivia , one of Francisco Pizarro 's lieutenants, who founded

2576-652: Is present-day Chile. Settlement sites from very early human habitation include Monte Verde, Cueva del Milodón and the Pali-Aike Crater 's lava tube . The Incas briefly extended their empire into what is now northern Chile, but the Mapuche (or Araucanians as they were known by the Spaniards) successfully resisted many attempts by the Inca Empire to subjugate them, despite their lack of state organization. They fought against

2688-577: Is provided by Bosch, Cleveringa and Meijer, 2000. The Last Interglacial climate is believed to have been warmer than the current Holocene. The temperature of the Last Interglacial peaked during the early part of the period, around 128,000 to 123,000 years Before Present , before declining during the latter half of the period. Changes in the Earth's orbital parameters from today (greater obliquity and eccentricity, and perihelion), known as Milankovitch cycles , probably led to greater seasonal temperature variations in

2800-601: Is suspended under the terms of the Antarctic Treaty , of which Chile is a signatory. It is the world's southernmost country that is geographically on the mainland. Chile controls Easter Island and Sala y Gómez Island, the easternmost islands of Polynesia, which it incorporated to its territory in 1888, and the Juan Fernández Islands , more than 600 km (370 mi) from the mainland. Also controlled but only temporarily inhabited (by some local fishermen) are

2912-521: Is the southernmost country in the world and the closest to Antarctica , stretching along a narrow strip of land between the Andes Mountains and the Pacific Ocean . Chile had a population of 17.5 million as of the latest census in 2017 and has a territorial area of 756,102 square kilometers (291,933 sq mi), sharing borders with Peru to the north, Bolivia to the northeast, Argentina to

The range of cold-adapted taxa like the woolly mammoth ( Mammuthus primigenius ) contracted towards refugia . Neanderthals managed to colonise

3248-574: The Canadian Arctic Archipelago : currently, the northern limit is further south at Kuujjuaq in northern Quebec . Coastal Alaska was warm enough during the summer due to reduced sea ice in the Arctic Ocean to allow Saint Lawrence Island (now tundra) to have boreal forest, although inadequate precipitation caused a reduction in the forest cover in interior Alaska and Yukon Territory despite warmer conditions. The prairie-forest boundary in

3360-720: The Great Plains of the United States lay further west near Lubbock, Texas , whereas the current boundary is near Dallas . Interglacial conditions ended on Antarctica while the Northern Hemisphere was still experiencing warmth. Sea level at peak was probably 6 to 9 metres (20 to 30 feet) higher than today, with Greenland contributing 0.6 to 3.5 m (2.0 to 11.5 ft), thermal expansion and mountain glaciers contributing up to 1 m (3.3 ft), and an uncertain contribution from Antarctica. A 2007 study found evidence that

3808-690: The Pacific Alliance , and joined the OECD in 2010. There are various theories about the origin of the word Chile . According to 17th-century Spanish chronicler Diego de Rosales , the Incas called the valley of the Aconcagua Chili by corruption of the name of a Picunche tribal chief ( cacique ) called Tili , who ruled the area at the time of the Incan conquest in the 15th century. Another theory points to

3920-514: The Weichselian . In contrast to e.g. the deposits in Denmark, the Last Interglacial deposits in the type area have never been found overlain by tills, nor in ice-pushed positions. Van Voorthuysen (1958) described the foraminifera from the type site, whereas Zagwijn (1961) published the palynology , providing a subdivision of this stage into pollen stages. At the end of the 20th century, the type site

On 17 December 2023, voters rejected a second new constitution proposal in a new constitutional referendum , written by the conservative-led Constitutional Council . A long and narrow coastal Southern Cone country on the west side of the Andes Mountains , Chile stretches over 4,300 km (2,670 mi) north to south, but only 350 km (217 mi) at its widest point east to west and 64 km (40 mi) at its narrowest point east to west, with an average width of 175 km (109 mi). This encompasses

4144-473: The global wave of megafauna extinctions that occurred during the following Last Glacial Period, has been suggested as a "baseline" reference point for the analysis and restoration of modern European ecosystems. Following the melting of the Laurentide Ice Sheet , a number of North American megafauna species migrated northwards to inhabit northern Canada and Alaska during the Last Interglacial, including

In the 20th century, up until the 1970s, Chile underwent a process of democratization and experienced rapid population growth and urbanization , while relying increasingly on exports from copper mining to support its economy . During the 1960s and 1970s, the country

The model (generated using observed greenhouse gas concentrations and Last Interglacial orbital parameters) generally reproduces these observations, leading them to conclude that these factors are enough to explain the Last Interglacial temperatures. Meltwater pulse 2B, approximately 133,000 BP, substantially weakened the Indian Summer Monsoon (ISM). Trees grew as far north as southern Baffin Island in

More than 500 people died (most from the ensuing tsunami ) and over a million people lost their homes. The earthquake was also followed by multiple aftershocks. Initial damage estimates were in the range of US$ 15–30 billion, around 10% to 15% of Chile's real gross domestic product. Chile achieved global recognition for

4704-504: The Earth". Another origin attributed to chilli is the onomatopoeic cheele-cheele —the Mapuche imitation of the warble of a bird locally known as trile . The Spanish conquistadors heard about this name from the Incas, and the few survivors of Diego de Almagro 's first Spanish expedition south from Peru in 1535–36 called themselves the "men of Chilli". Ultimately, Almagro is credited with

4816-715: The Greenland Ice Sheet Project (GISP2), the North Greenland Ice Core Project (NorthGRIP), and the North Greenland Eemian Ice Drilling (NEEM). Initially GISP2 seemed to overturn an earlier result discovered by GRIP. Based on the sharp fluctuations of the oxygen isotope ratio near the bottom of the GRIP core, it had been hypothesized that severe climate change occurred repeatedly during the last interglacial period in Greenland. However,

4928-533: The Greenland ice core site Dye 3 was glaciated during the Last Interglacial, which implies that Greenland could have contributed at most 2 m (6.6 ft) to sea level rise . Recent research on marine sediment cores offshore of the West Antarctic Ice Sheet suggest that the sheet melted during the Last Interglacial, and that ocean waters rose as fast as 2.5 meters per century. Global mean sea surface temperatures are thought to have been higher than in

Since anthropogenic factors are deeply involved in environmental issues such as greenhouse gases, they may also be related to climate change during the Eemian. Previous ice core drilling projects, including GRIP, were carried out at sites where horizontal ice flow

Because of the sea level drop since the Last Interglacial, exposed fossil coral reefs are common in the tropics, especially in the Caribbean and along the Red Sea coastlines. These reefs often contain internal erosion surfaces showing significant sea level instability during

5264-616: The Last Interglacial is equivalent to either all or part of it. The period falls into the Middle Paleolithic and is of some interest for the evolution of anatomically modern humans , who were present in Western Asia ( Skhul and Qafzeh hominins ) as well as in Southern Africa by this time, representing the earliest split of modern human populations that persists to the present time (associated with mitochondrial haplogroup L0 ). As

Scandinavia formed an island due to the area between the Gulf of Finland and the White Sea being drowned. Vast areas of northwestern Europe and the West Siberian Plain were inundated. The warmness of the interval allowed temperate-adapted taxa to extend their range considerably northward, with

The Arctic Last Interglacial climate was highly unstable, with pronounced temperature swings revealed by δO fluctuations in Greenlandic ice cores, though some of the instability inferred from Greenland ice core project records may be

5600-702: The Popular Unity platform also called for nationalization of Chile's major copper mines in the form of a constitutional amendment. The measure was passed unanimously by Congress. As a result, the Richard Nixon administration organized and inserted secret operatives in Chile, in order to swiftly destabilize Allende's government. In addition, US financial pressure restricted international economic credit to Chile. The economic problems were also exacerbated by Allende's public spending, financed mostly through printing money, and by poor credit ratings given by commercial banks. Simultaneously, opposition media, politicians, business guilds and other organizations helped to accelerate

5712-420: The Sapa Inca Tupac Yupanqui and his army. The result of the bloody three-day confrontation known as the Battle of the Maule was that the Inca conquest of the territories of Chile ended at the Maule river . In 1520, while attempting to circumnavigate the globe, Ferdinand Magellan discovered the southern passage now named after him (the Strait of Magellan ) thus becoming the first European to set foot on what

After these events, a movement for total independence, under the command of José Miguel Carrera (one of the most renowned patriots) and his two brothers Juan José and Luis Carrera , soon gained a wider following. Spanish attempts to re-impose arbitrary rule during what was called the Reconquista led to

5936-435: The War of the Pacific, Chile became a Naval Power in the Americas, even sending a ship in protests in the Panama crisis of 1885 against the United States intervention in the then Colombian territory. The United States and Chile had the Baltimore crisis which almost became a war as Chile was a potential threat to the intentions of hegemony from the United States in the Western Hemisphere. In 1902 Chile and Argentina received

6048-440: The analysis of the oxygen isotope ratio of the GRIP core excavated in 1992, it became clear that abrupt climate change occurred in Greenland during the last glacial period. This happened more than 20 times. It further became clear that the warm and cold periods alternated. Near the bottom of the GRIP core, oxygen isotope ratios fluctuated sharply; this was initially interpreted as an indication of repeated violent climate change during

6160-470: The armed forces bombarded the presidential palace , Allende apparently committed suicide. After the coup, Henry Kissinger told U.S. president Richard Nixon that the United States had "helped" the coup. In 1970, when Allende was first elected, Henry Kissinger had stated "I don't see why we need to stand by and watch a country go Communist due to the irresponsibility of its own people". A military junta, led by General Augusto Pinochet , took control of

6272-571: The banking sector was nationalized . Many enterprises within the copper , coal, iron, nitrate , and steel industries were expropriated , nationalized, or subjected to state intervention. Industrial output increased sharply and unemployment fell during the Allende administration's first year. Allende's program included advancement of workers' interests, replacing the judicial system with "socialist legality", nationalization of banks and forcing others to bankruptcy, and strengthening "popular militias" known as MIR. Started under former President Frei,

6384-435: The candidate of a coalition of 17 political parties called the Concertación , received an absolute majority of votes (55%). President Aylwin served from 1990 to 1994, in what was considered a transition period. In December 1993, Christian Democrat Eduardo Frei Ruiz-Tagle , the son of previous president Eduardo Frei Montalva, led the Concertación coalition to victory with an absolute majority of votes (58%). Frei Ruiz-Tagle

6496-532: The change in size is due to a variety of physical environmental factors. The best estimates based on the paleoclimate data show that the Greenland ice sheet is significantly reduced by even a small increase in the negative effects of climate change. A 2020 research paper suggests that the melting of the ice sheet that covers Greenland will accelerate much faster than previously predicted. Studies of nuclear isotopes and various atmospheric constituents provide detailed records of climate change over 100,000 years. From

As a result of the War of the Pacific with Peru and Bolivia (1879–83), Chile expanded its territory northward by almost one-third, eliminating Bolivia's access to the Pacific, and acquired valuable nitrate deposits, the exploitation of which led to an era of national affluence. Chile had joined

In the late 1980s, largely as a result of events such as the 1982 economic collapse and mass civil resistance in 1983–88, the government gradually permitted greater freedom of assembly, speech , and association, to include trade union and political activity. The government launched market-oriented reforms with Hernán Büchi as Minister of Finance. Chile moved toward

In October 1973, at least 72 people were murdered by the Caravan of Death . According to the Rettig Report and Valech Commission , at least 2,115 were killed, and at least 27,265 were tortured (including 88 children younger than 12 years old). In 2011, Chile recognized an additional 9,800 victims, bringing

7504-520: The destruction of many of the colony's principal settlements. Subsequent major insurrections took place in 1598 and in 1655. Each time the Mapuche and other native groups revolted, the southern border of the colony was driven northward. The abolition of slavery by the Spanish crown in 1683 was done in recognition that enslaving the Mapuche intensified resistance rather than cowing them into submission. Despite royal prohibitions, relations remained strained from continual colonialist interference. Cut off to

8176-631: The first rightist President in 20 years, defeating former President Eduardo Frei Ruiz-Tagle of the Concertación , for a four-year term succeeding Bachelet. Due to term limits, Sebastián Piñera did not stand for re-election in 2013, and his term expired in March 2014 resulting in Michelle Bachelet returning to office. Sebastián Piñera succeeded Bachelet again in 2018 as the President of Chile after winning

8288-612: The heartlands of North America from Alaska at the beginning of the Last Interglacial, giving rise to the giant long-horned bison Bison latifrons (which is first known from the Snowmass site in Colorado, dating to around 120,000 years ago) and ultimately all North American bison species, and marking the beginning of the Rancholabrean faunal age in North America. Also during this time period

8400-514: The higher latitudes of Europe during this time interval, after having retreated from the region due to unfavourable conditions during the Penultimate Glacial Period. However, unlike previous interglacials, they were absent from Britain, likely due to Britain being an island during this time. During the Last Interglacial, Neanderthals engaged in a variety of food-gathering activities, including fishing, as well as big-game hunting, including

8512-510: The ice sheet surface melted during the final interglacial period (the Eemian) because of the methane and rare gases collected from NEEM's ice core. The fact that the Greenland core remained stable during the temperature rise suggests that the Antarctic ice sheet shrank during the final interglacial period and contributed significantly to the increase in sea level. To accurately predict the response of

8624-640: The largest animals living in Europe at the time, straight-tusked elephants. Modern humans were present outside Africa in Arabia during this interval, as far east as the Persian Gulf . Chile Chile ( / ˈ tʃ ɪ l i / CHIL -ee or / ˈ tʃ ɪ l eɪ / CHIL -ay , Spanish: [ˈtʃile] ), officially the Republic of Chile , is a country in western South America . It

8736-529: The last interglacial period in Greenland. The first drilling of the Greenland Ice Core Project went only a few hundred meters into the glacier ice. But from 1989 to 1992 GRIP successfully drilled a 3029-meter ice core to the bed of the Greenland ice sheet at Summit ( 72°34.74′N 37°33.92′W  /  72.57900°N 37.56533°W  / 72.57900; -37.56533 ). In 1991, ice cores 783 to 2482 meters long were drilled, and an ice core

8848-419: The last interglacial period, when the temperature was about 8 °C ± 4 °C higher than it is now. During the 6000 years between 128,000 and 122,000 years ago, the ice sheet thickness decreased by 400 ± 250 m, and 122,000 years ago the ice sheet surface altitude was 130 ± 300 m higher than it is today. This shows that it is extremely rare for the ice sheet to melt even in the hot summer in Greenland. Rather,

8960-399: The middle of the Last Interglacial, a weakened Atlantic Meridional Overturning Circulation (AMOC) began to cool the eastern Mediterranean region. The period closed as temperatures steadily fell to conditions cooler and drier than the present, with a 468-year-long aridity pulse in central Europe at about 116,000 BC, and by 112,000 BC, ice caps began to form in southern Norway, marking

9072-402: The most recent point in time with a climate comparable to the Holocene, the Last Interglacial is also of relevance as a point of reference ( baseline ) for nature conservation. The Last Interglacial was first recognized from boreholes in the area of the city of Amersfoort , Netherlands , by Pieter Harting (1875). He named the beds "Système Eémien", after the river Eem on which Amersfoort

9184-652: The north by desert, to the south by the Mapuche, to the east by the Andes Mountains, and to the west by the ocean, Chile became one of the most centralized, homogeneous territories in Spanish America. Serving as a sort of frontier garrison , the colony found itself with the mission of forestalling encroachment by both the Mapuche and Spain's European enemies, especially the English and the Dutch . Buccaneers and pirates menaced

9296-433: The overall number of migrants was small. This effect might be related to externalities : the surrounding population adopted a similar behavior as the small non-European immigrant group, and new schools were created. Ironically, there might have been positive spillover effects from the educational investment made by migrants, at the same time numeracy might have been reduced by the greater inequality in these regions. However,

9408-551: The oxygen isotope ratio data of the GISP2 core that was excavated only 30 km away from the sampling point of the GRIP core did not match the GRIP data. It became clear that the ice layer structure was disturbed by folds at the bottom of the ice sheet in both cores, indicating that the interpretation that there was severe climate change during the final interglacial period may be incorrect. The GISP2 reconstructions are relatively old. Recent studies have raised questions about evaluating

9520-569: The peak of the Last Interglacial, the Northern Hemisphere winters were generally warmer and wetter than now, though some areas were actually slightly cooler than today. A cooling event similar to but not exactly mirroring the 8.2-kiloyear event is recorded from Beckentin during the E5 phase of the Eemian, some 6,290 years after the start of interglacial afforestation. A 2018 study based on soil samples from Sokli in northern Finland identified abrupt cold spells ca. 120,000 years ago caused by shifts in

9632-402: The population consisted of 259,646 inhabitants: 73.5% of European descent , 7.9% mestizos , 8.6% indigenous peoples and 9.8% blacks. Francisco Hurtado, Governor of the province of Chiloé , conducted a census in 1784 and found the population consisted of 26,703 inhabitants, 64.4% of whom were whites and 33.5% of whom were natives. The Diocese of Concepción conducted a census in areas south of

9744-455: The positive effects of immigration were apparently stronger. In 1808, Napoleon's enthronement of his brother Joseph as the Spanish King precipitated the drive by Chile for independence from Spain . A national junta in the name of Ferdinand – heir to the deposed king – was formed on 18 September 1810. The Government Junta of Chile proclaimed an autonomous government for Chile within

9856-1029: The range of the hippopotamus ( Hippopotamus amphibius ) notably extending as far north as North Yorkshire in northern England, though their range outside of southern Europe did not extend much further east of than the Rhine . The temperate landscapes of Europe were inhabited by large now extinct megafauna including the straight-tusked elephant ( Palaeoloxodon antiquus ), the narrow-nosed rhinoceros ( Stephanorhinus hemitoechus ), Merck's rhinoceros ( Stephanorhinus kirchbergensis ), Irish elk ( Megaloceros giganteus ) and aurochs ( Bos primigenius ), alongside still-living species like red deer ( Cervus elaphus ), fallow deer ( Dama dama ), roe deer ( Capreolus capreolus ) and wild boar ( Sus scrofa ), with predators including lions (the extinct Panthera spelaea ) and cave hyenas ( Crocuta ( Crocuta ) spelaea ), brown bears ( Ursus arctos ) and wolves ( Canis lupus ). The Last Interglacial ecosystems of Europe, which existed prior to

9968-426: The region in the mid-16th century, replacing Inca rule , but failed to conquer the independent Mapuche people who inhabited what is now south-central Chile. Chile emerged as a relatively stable authoritarian republic in the 1830s after their 1818 declaration of independence from Spain . During the 19th century, Chile experienced significant economic and territorial growth, putting an end to Mapuche resistance in

10080-551: The relationship between temperature and Delta-O-18 during the Holocene in view of the elevation changes in the ice cap at the GISP2 site. The GISP2 reconstructions changed the relationship between Delta-O-18 and temperature by a factor of two during the Holocene, while more recent reconstructions leave that relationship unchanged. Elevation change affects the Delta-O-18 record, and the older GISP2 reconstructions do not account for elevation changes. NorthGRIP aimed to collect ice during

10192-547: The result from the arbitral award of the Andes resolved by the British Crown . In 1903 the Puna de Atacama dispute was solved. In 1904 Chile and Bolivia signed a Treaty of Peace and Friendship which clarified the border between both countries. The Chilean economy partially degenerated into a system protecting the interests of a ruling oligarchy . By the 1920s, the emerging middle and working classes were powerful enough to elect

10304-480: The sea level will rise by approximately 7 meters if all the ice melts. The rise in sea levels due to ice sheet glaciers’ melt would make it impossible for people to live in coastal regions. Because there is no preserved ancient terrestrial sediment in Greenland, most ice sheet history is based on indirect records. Using the limited paleoclimate data, researchers have shown that the extent of ice in Greenland has changed significantly over time, and this suggests that

10416-647: The similarity of the valley of the Aconcagua with that of the Casma Valley in Peru, where there was a town and valley named Chili . Other theories say Chile may derive its name from a Native American word meaning either 'ends of the earth' or 'sea gulls'; from the Mapuche word chilli , which may mean 'where the land ends'" or from the Quechua chiri , 'cold', or tchili , meaning either 'snow' or "the deepest point of

10528-475: The small islands of San Ambrosio and San Felix . These islands are notable because they extend Chile's claim to territorial waters out from its coast into the Pacific Ocean. The northern Atacama Desert contains great mineral wealth, primarily copper and nitrates . The relatively small Central Valley, which includes Santiago, dominates the country in terms of population and agricultural resources. This area

10640-590: The stand as one of the high-income countries in South America by 1870. On 9 September 1888, Chile took possession of Easter Island by the signing of a mutual will agreement with the local king, thanks to the efforts of the Bishop of Tahiti, Monsignor José María Verdier since the island was constantly attacked by slave merchants. The naval officer Policarpo Toro represented the Chilean Government and Atamu Tekena

10752-566: The start of a new glacial period . The Eemian lasted about 1,500 to 3,000 years longer in Southern Europe than in Northern Europe. Kaspar et al. (GRL, 2005) performed a comparison of a coupled general circulation model (GCM) with reconstructed Last Interglacial temperatures for Europe. Central Europe (north of the Alps) was found to be 1–2 °C (1.8–3.6 °F) warmer than present; south of

10864-523: The successful rescue of 33 trapped miners in 2010. On 5 August 2010, the access tunnel collapsed at the San José copper and gold mine in the Atacama Desert near Copiapó in northern Chile, trapping 33 men 700 meters (2,300 ft) below ground. A rescue effort organized by the Chilean government located the miners 17 days later. All 33 men were brought to the surface two months later on 13 October 2010 over

10976-608: The total ice sheet and glacier ice outside Antarctica. The project was managed by a Steering Committee of the University of Bern 's Physics Institute, chaired by Professor Bernhard Stauffer. Funding came from eight European nations (Belgium, Denmark, France, Germany, Iceland , Italy, Switzerland, and the United Kingdom), and from the European Union . Studies of nuclear isotopes and various atmospheric constituents provided by

11088-448: The total number of killed, tortured or imprisoned for political reasons to 40,018. At the national stadium, filled with detainees, one of those tortured and killed was internationally known poet-singer Víctor Jara (see "Music and Dance", below). A new Constitution was approved by a controversial plebiscite on 11 September 1980, and General Pinochet became president of the republic for an eight-year term. After Pinochet obtained rule of

11200-420: The traditional Greenland ice cores. In view of this difficulty, EastGRIP installed a cold temperature chamber to keep the drilled ice below -30 °C immediately after the drilling, and efforts were made to minimize the destruction of ice cores by eliminating small steps of several tens of microns in the core field processing. The cold air prevents the expansion of air bubbles and keeps the ice from breaking. As

11312-506: The triple minister Diego Portales . Two other civil wars happened in Chile in the 1850s, one in 1851 and the other one in 1859 . Toward the end of the 19th century, the government in Santiago consolidated its position in the south by the Occupation of Araucanía . The Boundary treaty of 1881 between Chile and Argentina confirmed Chilean sovereignty over the Strait of Magellan but also made

11424-447: The uncertainty of the estimates due to inaccuracies in the analysis and adjustments in the isotope model. The later NEEM project extended the work of GRIP by excavating an ice core that shows the bottom melting and the folds at the NEEM site, and provides evidence concerning the entire final interglacial period. In Northern Greenland, it was warmest around 126,000 years before the beginning of

11536-575: The universalization of the name Chile , after naming the Mapocho valley as such. The older spelling "Chili" was in use in English until the early 20th century before switching to "Chile". Stone tool evidence indicates humans sporadically frequented the Monte Verde valley area as long as 18,500 years ago. About 10,000 years ago, migrating Indigenous peoples settled in fertile valleys and coastal areas of what

11648-519: Was a de facto dictatorship (although not really comparable in harshness or corruption to the type of military dictatorship that have often bedeviled the rest of Latin America). By relinquishing power to a democratically elected successor, Ibáñez del Campo retained the respect of a large enough segment of the population to remain a viable politician for more than thirty years, in spite of the vague and shifting nature of his ideology. When constitutional rule

11760-610: Was a research project organized through the European Science Foundation (ESF). The project ran from 1989 to 1995, with drilling seasons from 1990 to 1992. In 1988, the project was accepted as an ESF-associated program, and the fieldwork was started in Greenland in the summer of 1989. GRIP aimed to collect and investigate 3000-meter-long ice cores drilled at the apex of the Greenland ice sheet, also known as Summit Camp . The Greenland ice sheet comprises more than 90% of

11872-566: Was drilled to bedrock in 1992. The ice core was first taken to the University of Copenhagen in Denmark, where it was stored in a cold room at -26 °C. Five sections of ice core with a length of about 300 to 400 mm were shipped to Japan. A wide range of information related to past and present climatic and environmental changes can be analyzed from the ice. The glacier layers that are collected can reveal up to 500,000 years of evidence. Studies of isotopes and various atmospheric constituents in

11984-422: Was marked by severe left-right political polarization and turmoil, which culminated in the 1973 Chilean coup d'état that overthrew Salvador Allende 's democratically elected left-wing government . This was followed by a 16-year right-wing military dictatorship under Augusto Pinochet , which resulted in more than 3,000 deaths or disappearances . The regime ended in 1990, following a referendum in 1988 , and

12096-600: Was re-investigated using old and new data in a multi-disciplinary approach (Cleveringa et al., 2000). At the same time a parastratotype was selected in the Amsterdam glacial basin in the Amsterdam-Terminal borehole and was the subject of a multidisciplinary investigation (Van Leeuwen, et al., 2000). These authors also published a U/Th age for late Last Interglacial deposits from this borehole of 118,200 ± 6,300 years ago. A historical review of Dutch Last Interglacial research

12208-627: Was restored in 1932, a strong middle-class party, the Radicals, emerged. It became the key force in coalition governments for the next 20 years. During the period of Radical Party dominance (1932–52), the state increased its role in the economy. In 1952, voters returned Ibáñez del Campo to office for another six years. Jorge Alessandri succeeded Ibáñez del Campo in 1958, bringing Chilean conservatism back into power democratically for another term. The 1964 presidential election of Christian Democrat Eduardo Frei Montalva by an absolute majority initiated

12320-550: Was succeeded by a center-left coalition , which ruled until 2010. Chile is a developing country with a high-income economy and is one of the most economically and socially stable nations in South America. Chile also performs well in the region in terms of sustainability of the state and democratic development. Chile is a founding member of the United Nations , the Community of Latin American and Caribbean States (CELAC), and

12432-593: Was succeeded in 2000 by Socialist Ricardo Lagos , who won the presidency in an unprecedented runoff election against Joaquín Lavín of the rightist Alliance for Chile . In January 2006, Chileans elected their first female president, Michelle Bachelet Jeria , of the Socialist Party, defeating Sebastián Piñera , of the National Renewal party, extending the Concertación governance for another four years. In January 2010, Chileans elected Sebastián Piñera as

12544-526: Was the head of the Council of Rapanui. The Rapa Nui elders ceded sovereignty, without renouncing their titles as chiefs, the ownership of their lands, the validity of their culture and traditions and on equal terms. The Rapa Nui sold nothing, they were integrated in equal conditions to Chile. The 1891 Chilean Civil War brought about a redistribution of power between the President and Congress, and Chile established
