Siberia (/sˈbɪəriə/ sy-BEER-ee-ə; Russian: Сибирь, romanizedSibir', IPA: [sʲɪˈbʲirʲ] ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east.[3] It has formed part of the sovereign territory of Russia and its predecessor states since the centuries-long conquest of Siberia, which began with the fall of the Khanate of Sibir in the late 16th century and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over 13.1 million square kilometres (5,100,000 sq mi), but home to roughly a quarter of Russia's population. Novosibirsk and Omsk are the largest cities in the area.[4]

Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean. It is further defined as stretching from the territories within the Arctic Circle in the north to the northern borders of Kazakhstan, Mongolia, and China in the south, although the hills of north-central Kazakhstan are also commonly included.[3][5] The Russian government divides the region into three federal districts (groupings of Russian federal subjects), of which only the central one is officially referred to as "Siberian"; the other two are the Ural and Far Eastern federal districts, named for the Ural and Russian Far East regions that correspond respectively to the western and eastern thirds of Siberia in the broader sense.

Siberia is known for its long, harsh winters, with a January average of −25 °C (−13 °F).[6] Although it is geographically in Asia, Russian sovereignty and colonization since the 16th century have rendered the region culturally and ethnically European.[7] Over 85% of its population are of European descent,[8][9] chiefly Russian (comprising the Siberian sub-ethnic group), and Eastern Slavic cultural influences predominate throughout the region.[7] Nevertheless, there exist sizable ethnic minorities of Asian lineage, including various Turkic communities—many of which, such as the Yakuts, Tuvans, Altai, and Khakas, are Indigenous—along with the Mongolic Buryats, ethnic Koreans, and smaller groups of Samoyedic and Tungusic peoples (several of whom are classified as Indigenous small-numbered peoples by the Russian government), among many others.

Etymology

The origin of the name is uncertain.[10] The name's modern usage was recorded in the Russian language after the Russian conquest of Siberian Khanate.

Some sources say that "Siberia" originates from the Siberian Tatar word for "sleeping land" (Sib-ir). A further variant claims that the region was named after the Sibe people.[11] The Polish historian Chyliczkowski has proposed that the name derives from the proto-Slavic word for "north" (север, sever),[12] same as Severia. Anatole Baikaloff has dismissed this explanation. He said that the neighboring Chinese, Turks, and Mongolians, who have similar names for the region, would not have known Russian. He suggested that the name might be a combination of two words with Turkic origin, "su" (water) and "bir" (wild land).[13] Another account sees the name as the ancient tribal ethnonym of the Sirtya [ru] (also "Syopyr" (sʲɵpᵻr)), a Paleoasiatic ethnic group assimilated by the Nenets.

Mongolist György Kara posits that "Siberia" is derived from a Mongolic word "sibir", cognate with modern Buryat "sheber" or "dense forest".[14]

History

Prehistory

Siberia in Paleozoic times formed the continent of Siberia/Angaraland, which fused to Euramerica during the Late Carboniferous, as part of the formation of Pangea.[18]

The Siberian Traps were formed by one of the largest-known volcanic events of the last 251 million years of Earth's geological history. Their activity continued for a million years and some scientists consider it a possible cause of the "Great Dying" about 250 million years ago,[19] – estimated to have killed 90% of species existing at the time.[20]

The region has paleontological significance, as it contains bodies of prehistoric animals from the Pleistocene Epoch, preserved in ice or in permafrost. Specimens of Goldfuss cave lion cubs, Yuka the mammoth and another woolly mammoth from Oymyakon, a woolly rhinoceros from the Kolyma, and bison and horses from Yukagir have been found.[21] Remote Wrangel Island and the Taymyr Peninsula are believed to have been the last places on Earth to support woolly mammoths as isolated populations until their extinction around 2000 BC.[22]

At least three species of human lived in southern Siberia around 40,000 years ago: H. sapiens, H. neanderthalensis, and the Denisovans.[23] In 2010, DNA evidence identified the last as a separate species.[24]

Late Paleolithic southern Siberians appear to be related to paleolithic Europeans and the paleolithic Jōmon people of Japan.[25] Ancient DNA analysis has revealed that the oldest fossil known to carry the derived KITLG allele, which is responsible for blond hair in modern Europeans, is a 17,000 year old Ancient North Eurasian specimen from Siberia.[26] Ancient North Eurasian populations genetically similar to Mal'ta–Buret' culture and Afontova Gora were an important genetic contributor to Native Americans, Europeans, Ancient Central Asians, South Asians, and some East Asian groups (such as the Ainu people). Evidence from full genomic studies suggests that the first people in the Americas diverged from Ancient East Asians about 36,000 years ago and expanded northwards into Siberia, where they encountered and interacted with Ancient North Eurasians, giving rise to both Paleosiberian peoples and Ancient Native Americans, which later migrated towards the Beringian region, became isolated from other populations, and subsequently populated the Americas.[27][28]

Early history

Chukchi, one of many Indigenous peoples of Siberia. Representation of a Chukchi family by Louis Choris (1816)

During past millennia, different groups of nomads – such as the Enets, the Nenets, the Huns, the Xiongnu, the Scythians, and the Yugur – inhabited various parts of Siberia. The Afanasievo and Tashtyk cultures of the Yenisey valley and Altay Mountains are associated with the Indo-European migrations across Eurasia.[29] The proto-Mongol Khitan people also occupied parts of the region. In the 13th century, during the period of the Mongol Empire, the Mongols conquered a large part of this area.[30]

With the breakup of the Golden Horde, the autonomous Khanate of Sibir formed in the late-15th century. Turkic-speaking Yakut migrated north from the Lake Baikal region under pressure from the Mongol tribes during the 13th to 15th century.[31] Siberia remained a sparsely populated area. Historian John F. Richards wrote: "... it is doubtful that the total early modern Siberian population exceeded 300,000 persons".[32]

The growing power of Russia in the West began to undermine the Siberian Khanate in the 16th century. First, groups of traders and Cossacks began to enter the area. The Russian Army was directed to establish forts farther and farther east to protect new Russian settlers who migrated from Europe. Towns such as Mangazeya, Tara, Yeniseysk, and Tobolsk developed, the last becoming the de facto capital of Siberia from 1590. At this time, Sibir was the name of a fortress at Qashliq, near Tobolsk. Gerardus Mercator, in a map published in 1595, marks Sibier both as the name of a settlement and of the surrounding territory along a left tributary of the Ob.[33] Other sources[which?] contend that the Sibe, an Indigenous Tungusic people, offered fierce resistance to Russian expansion beyond the Urals. Some suggest that the term "Siberia" is a russification of their ethnonym.[11]

By the mid-17th century, Russia had established areas of control that extended to the Pacific Ocean. Some 230,000 Russians had settled in Siberia by 1709.[34] Siberia became one of the destinations for sending internal exiles. Exile was the main Russian punitive practice with more than 800,000 people exiled during the nineteenth century.[35][36]

The first great modern change in Siberia was the Trans-Siberian Railway, constructed during 1891–1916. It linked Siberia more closely to the rapidly industrialising Russia of Nicholas II (r. 1894–1917). Around seven million Russians moved to Siberia from Europe between 1801 and 1914.[37] Between 1859 and 1917, more than half a million people migrated to the Russian Far East.[38] Siberia has extensive natural resources: during the 20th century, large-scale exploitation of these took place, and industrial towns cropped up throughout the region.[39]

At 7:15 a.m. on 30 June 1908, the Tunguska Event felled millions of trees near the Podkamennaya Tunguska River (Stony Tunguska River) in central Siberia. Most scientists believe this resulted from the air burst of a meteor or a comet. Even though no crater has ever been found, the landscape in the (sparsely inhabited) area still bears the scars of this event.[40]

Soviet Union

In the early decades of the Soviet Union (especially in the 1930s and 1940s), the government used the Gulag state agency to administer a system of penal labour camps, replacing the previous katorga system.[41] According to semi-official Soviet estimates, which did not become public until after the fall of the Soviet government in 1991, from 1929 to 1953 more than 14 million people passed through these camps and prisons, many of them in Siberia. Another seven to eight million people were internally deported to remote areas of the Soviet Union (including entire nationalities or ethnicities in several cases).[42]

Half a million (516,841) prisoners died in camps from 1941 to 1943[43] during World War II.[citation needed] At other periods, mortality was comparatively lower.[44] The size, scope, and scale of the Gulag slave-labour camps remain subjects of much research and debate. Many Gulag camps operated in extremely remote areas of northeastern Siberia. The best-known clusters included Sevvostlag (the North-East Camps) along the Kolyma and Norillag near Norilsk, where 69,000 prisoners lived in 1952.[45] Major industrial cities of Northern Siberia, such as Norilsk and Magadan, developed from camps built by prisoners and run by former prisoners.[46]

Siberia spans an area of 13.1 million square kilometres (5,100,000 sq mi), covering the vast majority of Russia's total territory, and almost 9% of Earth's land surface (148,940,000 km2, 57,510,000 sq mi). It geographically falls in Asia, but is culturally and politically considered European, since it is a part of Russia.[7] Major geographical zones within Siberia include the West Siberian Plain and the Central Siberian Plateau.

Eastern and central Sakha comprises numerous north–south mountain ranges of various ages. These mountains extend up to almost 3,000 metres (9,800 ft), but above a few hundred metres they are almost completely devoid of vegetation. The Verkhoyansk Range was extensively glaciated in the Pleistocene, but the climate was too dry for glaciation to extend to low elevations. At these low elevations are numerous valleys, many of them deep and covered with larch forest, except in the extreme north where the tundra dominates. Soils are mainly turbels (a type of gelisol). The active layer tends to be less than one metre deep, except near rivers.

The highest point in Siberia is the active volcano Klyuchevskaya Sopka, on the Kamchatka Peninsula. Its peak reaches 4,750 metres (15,580 ft).

Geology

The West Siberian Plain, consisting mostly of Cenozoic alluvial deposits, is somewhat flat. In the mid-Pleistocene, many deposits on this plain resulted from ice dams which produced a large glacial lake. This mid- to late-Pleistocene lake blocked the northward flow of the Ob and Yenisey rivers, resulting in a redirection southwest into the Caspian and Aral seas via the Turgai Valley.[48] The area is very swampy, and soils are mostly peaty histosols and, in the treeless northern part, histels. In the south of the plain, where permafrost is largely absent, rich grasslands that are an extension of the Kazakh Steppe formed the original vegetation, most of which is no longer visible.[why?]

Belukha Mountain
Verkhoyansk Range

The Central Siberian Plateau is an ancient craton (sometimes named Angaraland) that formed an independent continent before the Permian (see the Siberian continent). It is exceptionally rich in minerals, containing large deposits of gold, diamonds, and ores of manganese, lead, zinc, nickel, cobalt, and molybdenum. Much of the area includes the Siberian Traps—a large igneous province. A massive eruptive period approximately coincided with the Permian–Triassic extinction event. The volcanic event is one of the largest known volcanic eruptions in Earth's history. Only the extreme northwest was glaciated during the Quaternary, but almost all is under exceptionally deep permafrost, and the only tree that can thrive, despite the warm summers, is the deciduous Siberian Larch (Larix sibirica) with its very shallow roots. Outside the extreme northwest, the taiga is dominant, covering a significant fraction of the entirety of Siberia.[49] Soils here are mainly turbels, giving way to spodosols where the active layer becomes thicker and the ice-content lower.

The Lena-Tunguska petroleum province includes the Central Siberian platform (some authors refer to it as the "Eastern Siberian platform"), bounded on the northeast and east by the Late Carboniferous through Jurassic Verkhoyansk foldbelt, on the northwest by the Paleozoic Taymr foldbelt, and on the southeast, south and southwest by the Middle Silurian to Middle Devonian Baykalian foldbelt.[50]: 228  A regional geologic reconnaissance study begun in 1932 and followed by surface and subsurface mapping revealed the Markova-Angara Arch (anticline). This led to the discovery of the Markovo Oil Field in 1962 with the Markovo—1 well, which produced from the Early Cambrian Osa Horizon bar-sandstone at a depth of 2,156 metres (7,073 ft).[50]: 243  The Sredne-Botuobin Gas Field was discovered in 1970, producing from the Osa and the Proterozoic Parfenovo Horizon.[50]: 244  The Yaraktin Oil Field was discovered in 1971, producing from the Vendian Yaraktin Horizon at depths of up to 1,750 metres (5,740 ft), which lies below Permian to Lower Jurassic basalt traps.[50]: 244 

Climate

Vegetation in Siberia mostly consists of taiga, with a tundra belt on the northern fringe, and a temperate forest zone in the south.

The climate of Siberia varies dramatically, but it typically has warm but short summers and long, brutally cold winters. On the north coast, north of the Arctic Circle, there is a very short (about one month long) summer.

Almost all the population lives in the south, along the route of the Trans-Siberian Railway. The climate in this southernmost part is humid continental climate (Köppen Dfa/Dfb or Dwa/Dwb) with cold winters but fairly warm summers lasting at least four months. The annual average temperature is about 0.5 °C (32.9 °F). January averages about −20 °C (−4 °F) and July about +19 °C (66 °F), while daytime temperatures in summer typically exceed 20 °C (68 °F).[51][52] With a reliable growing season, an abundance of sunshine and exceedingly fertile chernozem soils, southern Siberia is good enough for profitable agriculture, as was demonstrated in the early 20th century.

By far the most commonly occurring climate in Siberia is continental subarctic (Koppen Dfc, Dwc, or Dsc), with the annual average temperature about −5 °C (23 °F) and an average for January of −25 °C (−13 °F) and an average for July of +17 °C (63 °F),[53] although this varies considerably, with a July average about 10 °C (50 °F) in the taiga–tundra ecotone. The business-oriented website and blog Business Insider lists Verkhoyansk and Oymyakon, in Siberia's Sakha Republic, as being in competition for the title of the Northern Hemisphere's Pole of Cold. Oymyakon is a village which recorded a temperature of −67.7 °C (−89.9 °F) on 6 February 1933. Verkhoyansk, a town further north and further inland, recorded a temperature of −69.8 °C (−93.6 °F) for three consecutive nights: 5, 6 and 7 February 1933. Each town is alternately considered the Northern Hemisphere's Pole of Cold – the coldest inhabited point in the Northern hemisphere. Each town also frequently reaches 30 °C (86 °F) in the summer, giving them, and much of the rest of Russian Siberia, the world's greatest temperature variation between summer's highs and winter's lows, often well over 94–100+ °C (169–180+ °F) between the seasons.[54][failed verification]

Southwesterly winds bring warm air from Central Asia and the Middle East. The climate in West Siberia (Omsk, or Novosibirsk) is several degrees warmer than in the East (Irkutsk, or Chita) where in the north an extreme winter subarctic climate (Köppen Dfd, Dwd, or Dsd) prevails. But summer temperatures in other regions can reach +38 °C (100 °F). In general, Sakha is the coldest Siberian region, and the basin of the Yana has the lowest temperatures of all, with permafrost reaching 1,493 metres (4,898 ft). Nevertheless, Imperial Russian plans of settlement never viewed cold as an impediment. In the winter, southern Siberia sits near the center of the semi-permanent Siberian High, so winds are usually light in the winter.

Precipitation in Siberia is generally low, exceeding 500 millimetres (20 in) only in Kamchatka, where moist winds flow from the Sea of Okhotsk onto high mountains – producing the region's only major glaciers, though volcanic eruptions and low summer temperatures allow only limited forests to grow. Precipitation is high also in most of Primorye in the extreme south, where monsoonal influences can produce quite heavy summer rainfall.

Global warming

Researchers, including Sergei Kirpotin at Tomsk State University and Judith Marquand at Oxford University, warn that Western Siberia has begun to thaw as a result of global warming. The frozen peat bogs in this region may hold billions of tons of methane gas, which may be released into the atmosphere. Methane is a greenhouse gas 22 times more powerful than carbon dioxide.[56] In 2008 a research expedition for the American Geophysical Union detected levels of methane up to 100 times above normal in the atmosphere above the Siberian Arctic, likely the result of methane clathrates being released through holes in a frozen "lid" of seabed permafrost around the outfall of the Lena and the area between the Laptev Sea and East Siberian Sea.[57][58]

Since 1988, experimentation at Pleistocene Park has proposed to restore the grasslands of prehistoric times by conducting research on the effects of large herbivores on permafrost, suggesting that animals, rather than climate, maintained the past ecosystem. The nature reserve park also conducts climatic research on the changes expected from the reintroduction of grazing animals or large herbivores, hypothesizing that a transition from tundra to grassland would lead to a net change in energy emission to absorption ratios.[59]

According to Vasily Kryuchkov, approximately 31,000 square kilometers of the Russian Arctic has subjected to severe environmental disturbance.
