The 2019 wildfire season involves wildfires on multiple continents.
Below is a partial list of articles on wildfires from around the world in the year 2019.
A firebreak or double track is a gap in vegetation or other combustible material that acts as a barrier to slow or stop the progress of a bushfire or wildfire. A firebreak may occur naturally where there is an absence of vegetation or "fuel", such as a river, lake or canyon. Firebreaks may also be man-made, and many of these also serve as roads, such as a logging road, four-wheel drive trail, secondary road, or a highway.
Aerial firefighting, also known as waterbombing, is the use of aircraft and other aerial resources to combat wildfires. The types of aircraft used include fixed-wing aircraft and helicopters. Smokejumpers and rappellers are also classified as aerial firefighters, delivered to the fire by parachute from a variety of fixed-wing aircraft, or rappelling from helicopters. Chemicals used to fight fires may include water, water enhancers such as foams and gels, and specially formulated fire retardants such as Phos-Chek.
Wildfire suppression is a range of firefighting tactics used to suppress wildfires. Firefighting efforts depend on many factors such as the available fuel, the local atmospheric conditions, the features of the terrain, and the size of the wildfire. Because of this wildfire suppression in wild land areas usually requires different techniques, equipment, and training from the more familiar structure fire fighting found in populated areas. Working in conjunction with specially designed aerial firefighting aircraft, fire engines, tools, firefighting foams, fire retardants, and using various firefighting techniques, wildfire-trained crews work to suppress flames, construct fire lines, and extinguish flames and areas of heat in order to protect resources and natural wilderness. Wildfire suppression also addresses the issues of the wildland–urban interface, where populated areas border with wild land areas.
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."
A fire trail is a rural road built specifically for the purpose of access for "fire management purposes" including building containment lines and backburning operations.
Bushfires in Australia are a widespread and regular occurrence that have contributed significantly to shaping the nature of the continent over millions of years. Eastern Australia is one of the most fire-prone regions of the world, and its predominant eucalyptus forests have evolved to thrive on the phenomenon of bushfire. However, the fires can cause significant property damage and loss of both human and animal life. Bushfires have killed approximately 800 people in Australia since 1851, and billions of animals.
2015 Canadian wildfires were a series of wildfires across Canada and Alaska in July 2015 which spread smoke across most of North America. Over two hundred fires were ablaze across British Columbia, Saskatchewan, and Alberta.
The 2017 wildfire season involved wildfires on multiple continents. On Greenland, which is mostly covered by ice and permafrost, multiple fires occurred in melted peat bogs, described as "unusual, and possibly unprecedented". Popular media asked whether the wildfires were related to global warming. Research published by NASA states "climate change has increased fire risk in many regions", but caused "greater severity in the colder latitudes" where boreal and temperate forests exist, and scholars have described "a warm weather fluctuation that has become more frequent in recent decades" related to wildfires, without naming any particular event as being directly caused by global warming.
The 2019 Alberta wildfires have been described by NASA as part of an extreme fire season in the province. In 2019 there were a total of 803,393.32 hectares, which is over 3.5 times more land area burned than in the five-year average burned. The five year average is 747 fires destroying 146,360.08 hectares. There were 644 wildfires recorded in Alberta. By May 31, 10,000 people had been evacuated, 16 homes, and the Steen River CN railway bridge, had been destroyed.
The 2019–20 Australian bushfire season or Black Summer was one of the most intense and catastrophic fire seasons on record in Australia. It included a period of bushfires in many parts of Australia, which, due to its unusual intensity, size, duration, and uncontrollable dimension, was considered a megafire by media at the time. Exceptionally dry conditions, a lack of soil moisture, and early fires in Central Queensland led to an early start to the bushfire season, beginning in June 2019. Hundreds of fires burnt, mainly in the southeast of the country, until May 2020. The most severe fires peaked from December 2019 to January 2020.
The 2020 wildfire season involves wildfires on multiple continents.
A megafire is an exceptional fire that devastates a large area. They are characterised by their intensity, size, duration and uncontrollable scale. There is no precise scientific definition.
The 1974–75 Australian bushfire season is a series of bushfires, also known around the world as wildfires, that burned across Australia. Fires that summer burned up an estimated 117 million hectares. Approximately 15% of Australia's land mass suffered "extensive fire damage" including parts of New South Wales, the Northern Territory, Queensland, South Australia and Western Australia.
The 2016 wildfire season involved wildfires in multiple continents.
This is an environmental history of the 2020s. Environmental history refers to events and trends related to the natural environment and human interactions with it. Examples of human-induced events include biodiversity loss, climate change and holocene extinction.
The 2021 wildfire season involves wildfires on multiple continents. Even at halfway through the calendar year, wildfire seasons were larger than in previous history, with increased extreme weather caused by climate change strengthening the intensity and scale of fires.
