Forest lights: fires accelerating world:
The flames destroy everything
Forest fires accelerate worldwide – Forest lights: fires accelerating world
The “forest disturbances due to fires” increased since the beginning of the century. For example, alerted a study published on Monday.

More than 500 active lights. For example, nearly 6 million hectares who left for smoke: the current season of forest fires at Canada is already one of the worst ever recorded. Nevertheless, But it forest lights: fires accelerating world is not an isolated phenomenon. Meanwhile,
Monster fires Los Angeles At the beginning of the year, “Summer Black” Australian of 2019-2020 … Therefore, It is observed over the years. Consequently, a study has recently confirmed it, extreme forest fires, fueled by heat and drought, become more and more frequent.
Ever more affected forests
More Work published Monday In. Furthermore, the scientific journal “Proceedings of the National Academy of Sciences” find more generally that the damage caused by flames affect an increasingly large forest cover around the world.
“Global forests provide essential ecosystem services. ranging from climate regulation to the habitat of biodiversity, but they are subject to increasing pressure due to the combined impacts of the climate and the change of land use”, note the preamble forest lights: fires accelerating world the authors of the study led by Peter Potapo, of the Department of Geographic Sciences of the University of Maryland.
His colleagues. have analyzed the global archives of satellite data of the American Observation of the Landsat earth surface since 2001.
“We rely on a well -known. updated data set annually on the loss of canopy, including that due to fires,” said the main author. These data enter the changes to a resolution of around 30 × 30 meters by almost all the land emerged.
Canada. South America
Researchers thus observe a tendency to increase “significant of forest disturbances due to fires” since the beginning of the century. Globally, the average area devastated by fire in 2023 and 2024 was more than twice higher than the annual average of forest lights: fires accelerating world 2002-2022.
While the flames previously represented only a quarter of all the disturbances suffered by the forests (which also suffer from the conversion of massifs to agricultural land. to transport infrastructure, the exploitation of wood or mining, etc.), in terms of affected area, this percentage climbs today to more than 40%.
No region is spared but it is the tropical areas that pay the heaviest price. with an area disturbed by fires in the last two years three times the average since the beginning of the century. According to the researchers, Guyana and the Democratic Republic of Congo have, for example, suffered record losses.
Climate change in question
“In recent years. the most affected regions, in terms of carbon dioxide emissions linked to vegetation fires, have been Canada (in forest lights: fires accelerating world 2023 and 2024), Bolivia and the central regions of South America (in 2024), most of these regions having experienced their most extreme years,” notes Mark Parrington, scientific director Air quality (CAMS), which did not participate in the study.
He confirms that “despite a certain annual variability”. there is clearly over the past two decades “an upward trend in terms of estimated emissions, burnt surface, number and intensity of fires”.
The authors of the study also explain that the most spectacular increase occurs “in intact forests”. in other words those relatively distant from any sign of human activity. For them. “the unprecedented magnitude of fires in the most remote forests in the world is a potential pre-runner sign of the tips of ecosystems”.
“Climate change. industrial conversion and the increase in forest fires forest lights: fires accelerating world can indeed lead to a permanent conversion of forest biomes”, the massifs that can end up turning into savannah, “says Peter Potapov.
For study authors. global warming is the primary cause of this eating forest, since it is “responsible for the increase in the duration of the fire season, the drought of fuel and the frequency of meteorological events related to fires”.
Scientists also recall that the 1920s and 2024s have been the hottest ever recorded worldwide since 1850. If global warming does not turn on the flame alone. extreme heat and dryness have “favored the spread of accidental, intentional and natural fires”, especially in African and South American tropical forests.
