2021 Russian Wildfires
From June 2021, the taiga forests in Siberia and the Far East region of Russia were hit by unprecedented wildfires, following record-breaking heat and drought.Fires Scorch the Sakha Republic https://earthobservatory.nasa.gov/images/148537/fires-scorch-the-sakha-republic For the first time in recorded history, wildfire smoke reached the North Pole. Events Siberia In Yakutia, according to the Republic of Sakha's emergencies ministry, more than 250 fires were burning across roughly 5720 square kilometers of land on July 5. NASA's Aqua satellite also captured images of large fires raging in Kamchatka. In the city of Yakutsk, toxic smoke produced by the fires blanketed the city, reducing air quality to levels described as an "airpocalypse". Fires and smokes forced the Kolyma highway to be closed. A state of emergency was declared, and military planes and helicopters were used to douse the fires and to seed clouds to bring down rainfall. Boats along the River Lena were suspended. Aise ...

Taiga
Taiga (; rus, тайга́, p=tɐjˈɡa; relates to Mongolic and Turkic languages), generally referred to in North America as a boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest has been called the world's largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous United States. In Eurasia, it covers most of Sweden, Finland, much of Russia from Karelia in the west to the Pacific Ocean (including much of Siberia), much of Norway and Estonia, some of the Scottish Highlands, some lowland/coastal areas of Iceland, and areas of northern Kazakhstan, northern Mongolia, and northern Japan (on the island of Hokkaidō). The main tree species, depending on the length of the growing season and summer temperatures, vary across the world. The taiga of North America is mostly spruce, Scandinavian and Finnish taiga consists of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulaanbaatar
Ulaanbaatar (; mn, Улаанбаатар, , "Red Hero"), previously anglicized as Ulan Bator, is the capital and most populous city of Mongolia. It is the coldest capital city in the world, on average. The municipality is located in north central Mongolia at an elevation of about in a valley on the Tuul River. The city was originally founded in 1639 as a nomadic Buddhist monastic center, changing location 28 times, and was permanently settled at its current location in 1778. During its early years, as Örgöö (anglicized as Urga), it became Mongolia's preeminent religious center and seat of the Jebtsundamba Khutuktu, the spiritual head of the Gelug lineage of Tibetan Buddhism in Mongolia. Following the regulation of Qing-Russian trade by the Treaty of Kyakhta in 1727, a caravan route between Beijing and Kyakhta opened up, along which the city was eventually settled. With the collapse of the Qing Empire in 1911, the city was a focal point for independence efforts, leading ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2010 Russian Wildfires
The 2010 Russian wildfires were several hundred wildfires that broke out across Russia, primarily in European Russia, the west in summer 2010. They started burning in late July and lasted until early September 2010. The fires were associated with record-high temperatures, which were attributed to climate change—the summer had been the hottest recorded in Russian history—and drought. Russian President of Russia, President Dmitry Medvedev declared a state of emergency in seven regions, and 28 other regions were under a state of emergency due to crop failures caused by the drought. The fires cost roughly $15 billion in damages. A combination of the smoke from the fires, producing heavy smog blanketing large urban regions and the record-breaking 2010 Northern Hemisphere summer heat wave#Russia, heat wave put stress on the Russian healthcare system. Munich Re estimated that in all, 56,000 people died from the effects of the smog and the heat wave. The 2010 wildfires were the wo ...

2015 Russian Wildfires
From 12 to 16 April 2015, a series of wildfires spread across southern Siberia, Russia. In the Republic of Khakassia, 29 people were killed and 6,000 left homeless. Further east in Zabaykalsky Krai, four people died in wildfires near Chita. Damage was also reported in Inner Mongolia. Wildfires The series of wildfires began on Sunday morning, 12 April in Khakassia as intentional fires set to clear grass for agriculture were caught by strong winds and got out of control. Warm, dry weather help spread the fires, which quickly spread into the region's forests; daytime temperatures had reached 25 °C and spreading waves of flames soared to 3 meters in height. Russian television said the fires could be seen from space on satellite imagery. At 1 p.m. local time (6:00 GMT), a state of emergency was declared. Fire control planes and helicopters were dispatched by the Ministry of Emergency Situations, but the fires were not completely extinguished until around 6:00 a.m. o ...

2018 Russian Wildfires
Dry, warm conditions in the spring set the stage for fires in Siberia in May 2018. History In mid-July 2018, smoke from the fires could be seen by satellites reaching North America. ''The Siberian Times'' reported were burning. On July 24, the U.S. National Weather Service said smoke had crossed the Canada-U.S. border and reached Bellingham, Washington. Siberian fires were partly blamed by Environment Canada Environment and Climate Change Canada (ECCC; french: Environnement et Changement climatique Canada),Environment and Climate Change Canada is the applied title under the Federal Identity Program; the legal title is Department of the Environment ( ... which issued an air quality statement on July 25 for Prince George, BC. On July 29, the Puget Sound Clean Air Agency stated the Puget Sound region would experience "moderate air quality at times with some upper level smoke making for pretty sunsets. This smoke comes from distant fires, mostly originating from Siberia." See a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2019 Russian Wildfires
The 2019 Siberian wildfires began in July 2019 in poorly accessible areas of northern Krasnoyarsk Krai, Sakha Republic and Zabaykalsky Krai, all in Siberia, Russia. By the end of the month the size of the fires reached . As of 30 July, there had been no reported deaths or injuries due to the fires. The 2019 Siberia wildfires generated significant publicity, especially among social media users. As a result, a process of reviewing legal regulations regarding forest protection and forest fire extinguishing activities was started at the state level. Extent On 31 July 2019, Russian authorities reported that 3 million hectares () were on fire, an area roughly the size of Belgium. The smoke from the fires affected air quality in much of Siberia, including cities Novosibirsk, Krasnoyarsk, Omsk and other. Air travel was also disrupted. According to NASA data, on 31 July the smoke from burning Siberian forests reached the territory of Alaska and, possibly mixed with smoke from ...

Peatlands
A mire, peatland, or quagmire is a wetland area dominated by living peat-forming plants. Mires arise because of incomplete decomposition of organic matter, usually litter from vegetation, due to water-logging and subsequent anoxia. All types of mires share the common characteristic of being saturated with water, at least seasonally with actively forming peat, while having their own ecosystem. Like coral reefs, mires are unusual landforms that derive mostly from biological rather than physical processes, and can take on characteristic shapes and surface patterning. A quagmire is a floating (quaking) mire, bog, or any peatland being in a stage of hydrosere or hydrarch (hydroseral) succession, resulting in pond-filling yields underfoot. Ombrotrophic types of quagmire may be called quaking bog (quivering bog). Minerotrophic types can be named with the term quagfen. There are four types of mire: bog, fen, marsh and swamp. A bog is a mire that, due to its location relative to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permafrost Carbon Cycle
The permafrost carbon cycle or Arctic carbon cycle is a sub-cycle of the larger global carbon cycle. Permafrost is defined as subsurface material that remains below 0o C (32o F) for at least two consecutive years. Because permafrost soils remain frozen for long periods of time, they store large amounts of carbon and other nutrients within their frozen framework during that time. Permafrost represents a large carbon reservoir that is seldom considered when determining global terrestrial carbon reservoirs. Recent and ongoing scientific research however, is changing this view. The permafrost carbon cycle deals with the transfer of carbon from permafrost soils to terrestrial vegetation and microbes, to the atmosphere, back to vegetation, and finally back to permafrost soils through burial and sedimentation due to cryogenic processes. Some of this carbon is transferred to the ocean and other portions of the globe through the global carbon cycle. The cycle includes the exchange of carb ...

Climate Change In Russia
Climate change in Russia has serious effects on Climate of Russia, Russia's climate, including average temperatures and precipitation, as well as permafrost melting, more frequent Wildfires in Russia, wildfires, flooding and heatwaves. Changes may affect inland flash floods, more frequent coastal flooding and increased erosion reduced snow cover and glacier melting, and may ultimately lead to species losses and changes in ecosystem functioning. Russia is part of the Paris Agreement that the rise in global average temperature should be kept way below 2 °C. Since Russia is the fourth-largest greenhouse gas emitter in the world, action is needed to reduce the Effects of climate change, impacts of climate change on both regional and global scale. Greenhouse gas emissions Impacts on the natural environment Temperature and weather changes According to IPCC (2007), climate change affected temperature increase which is greater at higher northern latitudes in many ways.

Jet Stream
Jet streams are fast flowing, narrow, meandering thermal wind, air currents in the Atmosphere of Earth, atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Jet streams may start, stop, split into two or more parts, combine into one stream, or flow in various directions including opposite to the direction of the remainder of the jet. Overview The strongest jet streams are the polar jets around the Polar vortex, polar vortices, at above sea level, and the higher altitude and somewhat weaker subtropical jets at . The Northern Hemisphere and the Southern Hemisphere each have a polar jet and a subtropical jet. The northern hemisphere polar jet flows over the middle to northern latitudes of North America, Europe, and Asia and their intervening oceans, while the southern hemisphere polar jet mostly circles Antarctica, both all year round. Jet streams are the prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siberia Airs 2021176
Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲirʲ, a=Ru-Сибирь.ogg) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of Russia since the latter half of the 16th century, after the Russians conquered lands east of the Ural Mountains. Siberia is vast and sparsely populated, covering an area of over , but home to merely one-fifth of Russia's population. Novosibirsk, Krasnoyarsk and Omsk are the largest cities in the region. Because Siberia is a geographic and historic region and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia extends eastwards from the Ural Mountains to the Pacific Ocean, and includes most of the drainage basin of the Arctic Ocean. The river Yenisey divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of north-centr ...
