23% of tree cover losses result from wildfires and climate change increase their frequency and power. [136] The rising temperatures cause massive wildfires especially in the Boreal forests. One possible effect is the change of the forest composition. [137] Deforestation can also cause forests to become more fire prone through mechanisms such as ...
Cause: Slash-and-burn approach to deforest land for agriculture and effects of climate change and global warming due to unusually longer dry season and above average temperatures worldwide throughout 2019: Map; Amazon rainforest ecoregions as delineated by the WWF in white and the Amazon drainage basin in blue.
Human-caused fires are also responsible for 97% of wildfires that threaten homes. People often start wildfires through dangerous actions, including open burning, campfires, firearms and equipment use.
