Wildfires

Climate change has been a key factor in increasing the risk and extent of wildfires. Wildfire risk depends on a number of factors, including temperature, soil moisture, and the presence of trees, shrubs, and other potential fuel.

Several studies show links between climate change and increased frequency or severity of fire weather -- periods with a high fire risk due to a combination of high temperatures, low humidity, low rainfall and often high winds -- though some note anomalies in a few regions.

Rising global temperatures, more frequent heatwaves and associated droughts in some regions increase the likelihood of wildfires by stimulating hot and dry conditions, promoting fire weather, which can be used as an overall measure of the impact of climate change on the risk of fires occurring.

As the frequency and severity of wildfires increases, so does the amount of exposed population that is vulnerable to them
