Climate change promotes the type of weather that makes wildfires more likely. In some areas, an increase of wildfires has been attributed directly to climate change. Evidence from Earth's past also shows more fire in warmer periods. Climate change increases evapotranspiration . This can cause vegetation and soils to dry out. When
672-663: A benefit for people. Modern forest management often engages in prescribed burns to mitigate fire risk and promote natural forest cycles. However, controlled burns can turn into wildfires by mistake. Wildfires can be classified by cause of ignition, physical properties, combustible material present, and the effect of weather on the fire. Wildfire severity results from a combination of factors such as available fuels, physical setting, and weather. Climatic cycles with wet periods that create substantial fuels, followed by drought and heat, often precede severe wildfires. These cycles have been intensified by climate change . Wildfires are

This is the time of year in which severe wildfires are most likely, particularly in regions where snow is disappearing. Weather conditions are raising the risks of wildfires. But the total area burnt by wildfires has decreased. This is mostly because savanna has been converted to cropland , so there are fewer trees to burn. Climate variability including heat waves , droughts , and El Niño , and regional weather patterns, such as high-pressure ridges, can increase

They can move as fast as 10.8 kilometres per hour (6.7 mph) in forests and 22 kilometres per hour (14 mph) in grasslands. Wildfires can advance tangential to the main front to form a flanking front, or burn in the opposite direction of the main front by backing . They may also spread by jumping or spotting as winds and vertical convection columns carry firebrands (hot wood embers) and other burning materials through

Detection systems may include wireless sensor networks that act as automated weather systems: detecting temperature, humidity, and smoke. These may be battery-powered, solar-powered, or tree-rechargeable : able to recharge their battery systems using the small electrical currents in plant material. Larger, medium-risk areas can be monitored by scanning towers that incorporate fixed cameras and sensors to detect smoke or additional factors such as
2016-779: A susceptible area: an ignition source is brought into contact with a combustible material such as vegetation that is subjected to enough heat and has an adequate supply of oxygen from the ambient air. A high moisture content usually prevents ignition and slows propagation, because higher temperatures are needed to evaporate any water in the material and heat the material to its fire point . Dense forests usually provide more shade, resulting in lower ambient temperatures and greater humidity , and are therefore less susceptible to wildfires. Less dense material such as grasses and leaves are easier to ignite because they contain less water than denser material such as branches and trunks. Plants continuously lose water by evapotranspiration , but water loss

While more than 99% of the 10,000 new wildfires each year are contained, escaped wildfires under extreme weather conditions are difficult to suppress without a change in the weather. Wildfires in Canada and the US burn an average of 54,500 square kilometers (13,000,000 acres) per year. Above all, fighting wildfires can become deadly. A wildfire's burning front may also change direction unexpectedly and jump across fire breaks. Intense heat and smoke can lead to disorientation and loss of appreciation of

In the eastern extent of Siberia there are territories which are not clearly defined as either Siberia or the Far East , making the question of "what is Siberia?" one with no clear answer, and what is a "Siberian", one of self-identification . The most populous city of Siberia, as well as the third most populous city of Russia,
8064-740: The direction of the fire, which can make fires particularly dangerous. For example, during the 1949 Mann Gulch fire in Montana , United States, thirteen smokejumpers died when they lost their communication links, became disoriented, and were overtaken by the fire. In the Australian February 2009 Victorian bushfires , at least 173 people died and over 2,029 homes and 3,500 structures were lost when they became engulfed by wildfire. Siberia Siberia ( / s aɪ ˈ b ɪər i ə / sy- BEER -ee-ə ; Russian : Сибирь , romanized : Sibir' , IPA: [sʲɪˈbʲirʲ] )
8176-403: The district itself, but less commonly used to denote the federal district by people residing outside of it. Due to the different interpretations of Siberia, starting from Tyumen , to Chita , the territory generally defined as 'Siberia', some people will define themselves as 'Siberian', while others not. A number of factors in recent years, including the fomenting of Siberian separatism have made
8288-693: The earth's atmosphere has 415 parts per million of carbon, and the destruction of the Amazon would add about 38 parts per million. Some research has shown wildfire smoke can have a cooling effect. Research in 2007 stated that black carbon in snow changed temperature three times more than atmospheric carbon dioxide. As much as 94 percent of Arctic warming may be caused by dark carbon on snow that initiates melting. The dark carbon comes from fossil fuels burning, wood and other biofuels, and forest fires. Melting can occur even at low concentrations of dark carbon (below five parts per billion)". Wildfire prevention refers to
8400-411: The economic and safety benefits of protecting structures and human life. The demand for timely, high-quality fire information has increased in recent years. Fast and effective detection is a key factor in wildfire fighting. Early detection efforts were focused on early response, accurate results in both daytime and nighttime, and the ability to prioritize fire danger. Fire lookout towers were used in
8512-575: 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
8624-472: The extreme northwest, the taiga is dominant, covering a significant fraction of the entirety of Siberia. 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
8736-402: The fire front. Especially large wildfires may affect air currents in their immediate vicinities by the stack effect : air rises as it is heated, and large wildfires create powerful updrafts that will draw in new, cooler air from surrounding areas in thermal columns . Great vertical differences in temperature and humidity encourage pyrocumulus clouds , strong winds, and fire whirls with
8848-417: The fire heats both the surrounding air and woody material through convection and thermal radiation . First, wood is dried as water is vaporized at a temperature of 100 °C (212 °F). Next, the pyrolysis of wood at 230 °C (450 °F) releases flammable gases. Finally, wood can smolder at 380 °C (720 °F) or, when heated sufficiently, ignite at 590 °C (1,000 °F). Even before
8960-452: The flames of a wildfire arrive at a particular location, heat transfer from the wildfire front warms the air to 800 °C (1,470 °F), which pre-heats and dries flammable materials, causing materials to ignite faster and allowing the fire to spread faster. High-temperature and long-duration surface wildfires may encourage flashover or torching : the drying of tree canopies and their subsequent ignition from below. Wildfires have
9072-421: The flammable material present, its vertical arrangement and moisture content, and weather conditions. Fuel arrangement and density is governed in part by topography , as land shape determines factors such as available sunlight and water for plant growth. Overall, fire types can be generally characterized by their fuels as follows: Wildfires occur when all the necessary elements of a fire triangle come together in
9184-441: The force of tornadoes at speeds of more than 80 kilometres per hour (50 mph). Rapid rates of spread, prolific crowning or spotting, the presence of fire whirls, and strong convection columns signify extreme conditions. Intensity also increases during daytime hours. Burn rates of smoldering logs are up to five times greater during the day due to lower humidity, increased temperatures, and increased wind speeds. Sunlight warms
9296-450: The ground during the day which creates air currents that travel uphill. At night the land cools, creating air currents that travel downhill. Wildfires are fanned by these winds and often follow the air currents over hills and through valleys. Fires in Europe occur frequently during the hours of 12:00 p.m. and 2:00 p.m. Wildfire suppression operations in the United States revolve around
9408-452: The hills of north-central Kazakhstan are also commonly included. 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
9520-461: The historic site, fire crews trimmed low-hanging tree branches and built a fire line around the monument site. They also wrapped the tree scarred by the Japanese balloon bomb explosion and the stone monument in a fire-resistant material similar to the material used for firefighters' emergency shelters. As a result, when the fire passed through the adjacent forest, the monument was undamaged. Lightning
9632-440: The infrared signature of carbon dioxide produced by fires. Additional capabilities such as night vision , brightness detection, and color change detection may also be incorporated into sensor arrays . The Department of Natural Resources signed a contract with PanoAI for the installation of 360 degree 'rapid detection' cameras around the Pacific northwest, which are mounted on cell towers and are capable of 24/7 monitoring of
9744-470: The involvement of humans include lightning , volcanic eruptions , sparks from rock falls, and spontaneous combustions . Sources of human-caused fire may include arson, accidental ignition, or the uncontrolled use of fire in land-clearing and agriculture such as the slash-and-burn farming in Southeast Asia. In the tropics , farmers often practice the slash-and-burn method of clearing fields during
9856-474: The local population, but often met resistance, such as two campaigns in 1187 and 1193 mentioned in chronicles that were defeated. After Novgorod was annexed by Moscow , the newly emerging centralized Russian state also laid claim to the region, with Ivan III of Russia sending expeditionary forces to Siberia in 1483 and 1499–1500. The Russians received tribute, but contact with the tribes ceased after they left. The growing power of Russia began to undermine
9968-598: 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. 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. The first great modern change in Siberia was the Trans-Siberian Railway , constructed during 1891–1916. It linked Siberia more closely to
10080-553: 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), 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
10192-484: 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 . Other sources 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. By
10304-400: 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
10416-457: The only kremlin in Siberia), Tomsk (formerly a wealthy merchant's town) and Irkutsk (former seat of Eastern Siberia's governor general, near lake Baikal). Other major cities include: Barnaul , Kemerovo , Krasnoyarsk , Novokuznetsk , Tyumen . Wider definitions of geographic Siberia also include the cities of: Chelyabinsk and Yekaterinburg in the Urals, Khabarovsk and Vladivostok in
10528-480: The preemptive methods aimed at reducing the risk of fires as well as lessening its severity and spread. Prevention techniques aim to manage air quality, maintain ecological balances, protect resources, and to affect future fires. Prevention policies must consider the role that humans play in wildfires, since, for example, 95% of forest fires in Europe are related to human involvement. Wildfire prevention programs around
10640-406: The rapidly industrialising Russia of Nicholas II ( r. 1894–1917 ). Around seven million Russians moved to Siberia from Europe between 1801 and 1914. Between 1859 and 1917, more than half a million people migrated to the Russian Far East. Siberia has extensive natural resources: during the 20th century, large-scale exploitation of these took place, and industrial towns cropped up throughout
10752-461: 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'. Another account sees the name as the ancient tribal ethnonym of the Sihirtia or Sirtya (also Syopyr [sʲɵpᵻr])), a hypothetical Paleo-Asiatic ethnic group assimilated by the Nenets . Mongolist György Kara posits that the toponym Siberia
10864-539: The region. 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. In the early decades of
10976-723: The region. In the 13th century, during the period of the Mongol Empire , the Mongols conquered a large part of this area. With the breakup of the Golden Horde , the autonomous Khanate of Sibir was formed in the late-15th century. Turkic-speaking Yakut migrated north from the Lake Baikal region under pressure from the Mongol tribes from the 13th to 15th centuries. Siberia remained a sparsely populated area. Historian John F. Richards wrote: "it
11088-551: 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. According to Vasily Kryuchkov, approximately 31,000 square kilometers of the Russian Arctic has subjected to severe environmental disturbance. The term "Siberia" has both a long history and wide significance, and association. The understanding, and association of "Siberia" have gradually changed during
11200-404: The risk and alter the behavior of wildfires dramatically. Years of high precipitation can produce rapid vegetation growth, which when followed by warmer periods can encourage more widespread fires and longer fire seasons. High temperatures dry out the fuel loads and make them more flammable, increasing tree mortality and posing significant risks to global forest health. Since the mid-1980s, in
11312-492: The second largest wildfire in the United States of the 2021 wildfire season . The Bootleg Fire was first reported on July 6, 2021, at around 1:42 pm PDT near Beatty , Oregon . The Bootleg Fire merged with the smaller Log Fire to the east on July 19, 2021. As the Bootleg Fire burned east, it approached Mitchell Monument , a memorial to the only civilians killed in the 48 U.S. states during World War II . To protect
11424-399: The techniques used can be as simple as throwing sand or beating the fire with sticks or palm fronds. In more advanced nations, the suppression methods vary due to increased technological capacity. Silver iodide can be used to encourage snow fall, while fire retardants and water can be dropped onto fires by unmanned aerial vehicles , planes , and helicopters . Complete fire suppression
11536-469: 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 –
11648-936: The use of planes, helicopter, or UAVs can provide a wider view and may be sufficient to monitor very large, low risk areas. These more sophisticated systems employ GPS and aircraft-mounted infrared or high-resolution visible cameras to identify and target wildfires. Satellite-mounted sensors such as Envisat 's Advanced Along Track Scanning Radiometer and European Remote-Sensing Satellite 's Along-Track Scanning Radiometer can measure infrared radiation emitted by fires, identifying hot spots greater than 39 °C (102 °F). The National Oceanic and Atmospheric Administration 's Hazard Mapping System combines remote-sensing data from satellite sources such as Geostationary Operational Environmental Satellite (GOES), Moderate-Resolution Imaging Spectroradiometer (MODIS), and Advanced Very High Resolution Radiometer (AVHRR) for detection of fire and smoke plume locations. However, satellite detection
11760-425: 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). Although it is geographically in Asia, Russian sovereignty and colonization since the 16th century has led to perceptions of the region as culturally and ethnically European. Over 85% of its population are of European descent , chiefly Russian (comprising
11872-411: The wildfires. While direct emissions of harmful pollutants can affect first responders and residents, wildfire smoke can also be transported over long distances and impact air quality across local, regional, and global scales. The health effects of wildfire smoke, such as worsening cardiovascular and respiratory conditions, extend beyond immediate exposure, contributing to nearly 16,000 annual deaths,
11984-559: 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
12096-519: The world may employ techniques such as wildland fire use (WFU) and prescribed or controlled burns . Wildland fire use refers to any fire of natural causes that is monitored but allowed to burn. Controlled burns are fires ignited by government agencies under less dangerous weather conditions. Other objectives can include maintenance of healthy forests, rangelands, and wetlands, and support of ecosystem diversity. Strategies for wildfire prevention, detection, control and suppression have varied over
12208-466: The years. One common and inexpensive technique to reduce the risk of uncontrolled wildfires is controlled burning : intentionally igniting smaller less-intense fires to minimize the amount of flammable material available for a potential wildfire. Vegetation may be burned periodically to limit the accumulation of plants and other debris that may serve as fuel, while also maintaining high species diversity. While other people claim that controlled burns and
12320-480: 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
12432-762: Was organized in South Africa's Kruger National Park to validate fire detection products including the new VIIRS active fire data. In advance of that campaign, the Meraka Institute of the Council for Scientific and Industrial Research in Pretoria, South Africa, an early adopter of the VIIRS 375 m fire product, put it to use during several large wildfires in Kruger. Since 2021 NASA has provided active fire locations in near real-time via
12544-507: Was the cause of the fire. The fire was 100% contained on August 15, 2021. At one point, over 2,200 personnel were fighting the fire. Several hundred square miles of southern Oregon, in Klamath and Lake counties, were under evacuation orders of various degrees of severity. A total of 408 buildings were destroyed by the fire, including 161 houses and 247 outbuildings. The fire also destroyed 342 vehicles. The historic Merritt Creek trestle along
