This is a list of the largest fires of the 21st century.
The Department of Environment and Conservation (DEC) was a department of the Government of Western Australia that was responsible for implementing the state's conservation and environment legislation and regulations. It was formed on 1 July 2006 by the amalgamation of the Department of Environment and the Department of Conservation and Land Management.
One of the most extensive bushfire seasons in Australia's history. Victoria experienced the longest continuously burning bushfire complex in Australia's history, with fires in the Victorian Alps and Gippsland burning over 1 million hectares of land over the course of 69 days. See Bushfires in Australia for an explanation of regional seasons.
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.
A bushfire season occurred predominantly from June 2009 to May 2010. Increased attention has been given to this season as authorities and government attempt to preempt any future loss of life after the Black Saturday bushfires during the previous season, 2008–09. Long range weather observations predict very hot, dry and windy weather conditions during the summer months, leading to a high risk of bushfire occurrence.
The summer of 2012–13 had above average fire potential for most of the southern half of the continent from the east coast to the west. This is despite having extensive fire in parts of the country over the last 12 months. The reason for this prediction is the abundant grass growth spurred by two La Niña events over the last two years.
The 2013 New South Wales bushfires were a series of bushfires in Australia across the state of New South Wales primarily starting, or becoming notable, on 13 October 2013; followed by the worst of the fires beginning in the Greater Blue Mountains Area on 16 and 17 October 2013.
The bushfire season in the summer of 2014–15, was expected to have the potential for many fires in eastern Australia after lower than expected rainfall was received in many areas. Authorities released warnings in the early spring that the season could be particularly bad.
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.
The most destructive bushfire season in terms of property loss since the 2008–09 Australian bushfire season, occurred in the summer of 2015–16, with the loss of 408 houses and at least 500 non-residential buildings as a result of wild fires between 1 June 2015 and 31 May 2016. The season also suffered the most human fatalities since the 2008–09 Australian bushfire season; 6 died in Western Australia, 2 in South Australia and 1 in New South Wales. 8 deaths were as a direct result of fire, and a volunteer firefighter died due to unrelated health complications while on duty.
2019 United Kingdom wildfires were a series of wildfires that began on 26 February 2019 and ended on 18 May 2019. The series of wildfires was considered unusual due to the fact that they took place early in the year. Areas affected by the wildfires in 2019 included those that had already been burnt by wildfires during the summer of 2018. The fires have created many air pollution problems for the UK. The causes of most of the fires have been attributed to much higher than average temperatures and drought conditions that have prevailed since the spring of 2018. There were 137 wildfires larger than 25 hectares (250,000 m2) recorded in the United Kingdom in 2019. This beats the previous record of 79 from 2018.
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.
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.
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. For the first time in recorded history, wildfire smoke reached the North Pole.
In 2024, far-reaching wildfires ignited and spread across large areas of Russian territory, primarily in Siberia and also in southern regions. The wildfires resulted in a burnt area of 8.8 million hectares by July 18, and carbon emissions of 6.8 megatons by July 1, equaling the combined June-July emissions of 2023 in just one month.
The 2024 South American wildfires refer to a colossal series of wildfires that significantly impacted several neighboring South American countries, including Bolivia, Brazil, Chile, Colombia, Ecuador, and Peru. Based on Global Wildfire Information System satellite imaging, about 346,112 wildfire hotspots damaged or destroyed 85,866,867 hectares. The massive area burned was primarily caused by anthropogenic climate change and the resulting consequences of the 2023–2024 South American drought on fire conditions. The wildfires caused significant deforestation of the Amazon rainforest, and also impacted several other international biomes including the Pantanal wetlands, becoming the second largest series of wildfires in the 21st century next to the 2023–24 Australian bushfire season, with the 2024 Brazil wildfires alone reaching fourth in area burned.
The 2024 Argentina wildfires refer to significant outbreaks of wildfires primarily across Northern and Central Argentina that devastated large stretches of forests and farming land. The intensity and spread of the wildfires markedly increased in August and September 2024 due to drought conditions and elevated temperatures.
the Commonwealth Royal Commission into National Natural Disaster Arrangements 'struggled to obtain consistent burnt area data on a national scale', and found estimates of area burnt that ranged from 24.3 to 33.8 million hectares (…) The Commonwealth Department of Agriculture, Water and the Environment subsequently developed the National Indicative Aggregated Fire Extent Datasets in 2020, which estimated 39.8 million hectares were burnt in the 2019–20 fires.
forest fires that have burned more than 62,300 square miles since the beginning of the year, according to Greenpeace (…) The ministry estimates that the area burned in forest fires this year at slightly more than 30,000 square miles
