Megafire (fire)
A megafire is an extraordinary fire that devastates a large area. They are characterized by their intensity, size, duration, and uncontrollable dimension. There is no precise scientific definition. Definition The concept may vary by region or country. In Europe, they are characterized as beginning at 1,000 hectares (2,470 acres), in size, while in the United States and elsewhere, they may be classified beginning at 10,000 hectares (24,710 acres). Another figure used in the United States is . A recent NASA study expands the megafire definition to include a variety of factors: "Between climate change and almost a century of fire exclusion, forest fires have become more extreme in size, severity, complexity of behavior and resistance to extinction. These fires are commonly referred as megafires and are at the extremes of historical variations.” Using one definition, only 3% of all fires reach "megafire" status, yet they are responsible for more than 50% of burned surface ...

Cumulonimbus Flammagenitus
The cumulonimbus flammagenitus cloud (CbFg), also known as the pyrocumulonimbus cloud, is a type of cumulonimbus cloud that forms above a source of heat, such as a wildfire or volcanic eruption, and may sometimes even extinguish the fire that formed it. It is the most extreme manifestation of a flammagenitus cloud. According to the American Meteorological Society’s Glossary of Meteorology, a flammagenitus is "a cumulus cloud formed by a rising thermal from a fire, or enhanced by buoyant plume emissions from an industrial combustion process." Analogous to the meteorological distinction between cumulus and cumulonimbus, the CbFg is a fire-aided or –caused convective cloud, like a flammagenitus, but with considerable vertical development. The CbFg reaches the upper troposphere or even lower stratosphere and may involve precipitation (although usually light), hail, lightning, extreme low-level winds, and in some cases even tornadoes. The combined effects of these phenome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bootleg Fire
The Bootleg Fire, named after the nearby Bootleg Spring, was a large wildfire that started near Beatty, Oregon, on July 6, 2021. Before being fully contained on 15 August 2021, it had burned . It is the third-largest fire in the history of Oregon since 1900. At the fire's fastest growth in mid July, it grew at about per hour, and it became the second largest wildfire in the United States of the 2021 wildfire season. Events July 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 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2020 California Wildfires
The 2020 California wildfire season, part of the 2020 Western United States wildfire season, was a record-setting year of wildfires in California. By the end of the year, 9,917 fires had burned , more than 4% of the state's roughly 100 million acres of land, making 2020 the largest wildfire season recorded in California's modern history (according to the California Department of Forestry and Fire Protection), though roughly equivalent to the pre-1800 levels which averaged around 4.4 million acres yearly and up to 12 million in peak years. California's August Complex fire has been described as the first "gigafire", burning over 1 million acres across seven counties, an area larger than the state of Rhode Island. The fires destroyed over 10,000 structures and cost over $12.079 billion (2020 USD) in damages, including over $10 billion in property damage and $2.079 billion in fire suppression costs. The intensity of the fire season has been attributed to a combination of more t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
August Complex Fire
The August Complex was a massive wildfire that burned in the Coast Range of Northern California, in Glenn, Lake, Mendocino, Tehama, Trinity, and Shasta Counties. The complex originated as 38 separate fires started by lightning strikes on August 16–17, 2020. Four of the largest fires, the Doe, Tatham, Glade, and Hull fires, had burned together by August 30. On September 9, the Doe Fire, the main fire of the August Complex, surpassed the 2018 Mendocino Complex to become both the single-largest wildfire and the largest fire complex in recorded California history. On September 10, the combined Doe Fire also merged with the Elkhorn Fire (originally a separate incident) and the Hopkins Fire, growing substantially in size. By the time it was extinguished on November 12, the August Complex fire had burned a total of , or , about 1% of California's 100 million acres of land, an area larger than the state of Rhode Island. The fire largely burned within the Mendocino National For ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reuters
Reuters ( ) is a news agency owned by Thomson Reuters Corporation. It employs around 2,500 journalists and 600 photojournalists in about 200 locations worldwide. Reuters is one of the largest news agencies in the world. The agency was established in London in 1851 by the German-born Paul Reuter. It was acquired by the Thomson Corporation of Canada in 2008 and now makes up the media division of Thomson Reuters. History 19th century Paul Reuter worked at a book-publishing firm in Berlin and was involved in distributing radical pamphlets at the beginning of the Revolutions in 1848. These publications brought much attention to Reuter, who in 1850 developed a prototype news service in Aachen using homing pigeons and electric telegraphy from 1851 on, in order to transmit messages between Brussels and Aachen, in what today is Aachen's Reuters House. Reuter moved to London in 1851 and established a news wire agency at the London Royal Exchange. Headquartered in London, Reuter' ...

Camp Fire (2018)
The Camp Fire was the deadliest and most destructive wildfire in California's history, and the most expensive natural disaster in the world in 2018 in terms of insured losses. Named after Camp Creek Road, its place of origin, the fire started on Thursday, November 8, 2018, in Northern California's Butte County. Ignited by a faulty electric transmission line, the fire originated above several communities and an east wind drove the fire downhill through developed areas. After exhibiting extreme fire spread, fireline intensity, and spotting behaviors through the rural community of Concow, an urban firestorm formed in the foothill town of Paradise. Drought was a factor: Paradise, which typically sees five inches of autumn rain by November 12, had only received one-seventh of an inch by that date in 2018. With the arrival of the first winter rainstorm of the season, the fire reached 100 percent containment after seventeen days on November 25. The Camp Fire caused at least 85 civi ...

Congo Basin
The Congo Basin (french: Bassin du Congo) is the sedimentary basin of the Congo River. The Congo Basin is located in Central Africa, in a region known as west equatorial Africa. The Congo Basin region is sometimes known simply as the Congo. It contains some of the largest tropical rainforests in the world and is an important source of water used in agriculture and energy generation. The rainforest in the Congo Basin is the largest rainforest in Africa and second only to the Amazon rainforest in size, with 300 million hectares compared to the 800 million hectares in the Amazon. Because of its size and diversity, many experts have characterized the basin's forest as important for mitigating climate change because of its role as a carbon sink. However, deforestation and degradation of the ecology by the impacts of climate change may increase stress on the forest ecosystem, in turn making the hydrology of the basin more variable. A 2012 study found that the variability in precipita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Basin
In biogeography, the Mediterranean Basin (; also known as the Mediterranean Region or sometimes Mediterranea) is the region of lands around the Mediterranean Sea that have mostly a Mediterranean climate, with mild to cool, rainy winters and warm to hot, dry summers, which supports characteristic Mediterranean forests, woodlands, and scrub vegetation. Geography The Mediterranean Basin covers portions of three continents: Europe, Africa, and Asia. It is distinct from the drainage basin, which extends much further south and north due to major rivers ending in the Mediterranean Sea, such as the Nile and Rhône. Conversely, the Mediterranean Basin includes regions not in the drainage basin. It has a varied and contrasting topography. The Mediterranean Region offers an ever-changing landscape of high mountains, rocky shores, impenetrable scrub, semi-arid steppes, coastal wetlands, sandy beaches and a myriad islands of various shapes and sizes dotted amidst the clear blue sea.

Siberia
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-ce ...
