Wildfire rates are at an all-time high given the current state of the climate causing rising temperatures and dry vegetation. We're witnessing this all over the globe - but most notably in the U.S.

Important wildfire statistics

• 4.5 million U.S. homes are at high or extreme risk from wildfires. (Verisk)
• There were 58,985 wildfires in 2021, which affected 7.1 million acres, compared to just 18,229 wildfires and 1,323,666 acres lost in 1983 when official record-keeping began. (NIFC)
• There was a 17% increase from 2019 to 2021 in U.S. wildfires and a 223% increase since 1983. (NIFC)
• Humans cause as many as 90% of wildfires. (U.S. Department of Interior)
• Five of California’s top 20 biggest wildfires occurred in 2020. (iii)
• 2020 wildfires in the U.S. caused $16.5 billion in damages, making it the third-costliest year on record; 2017 being the highest at $24 billion and 2018 a close second at $22 billion. These figures do not account for indirect damages, which experts estimate cost around $150 billion for the record-setting 2018 wildfire season. (Yale Climate Connections)
• 2020 wildfires cost California 4.2 million acres of land, 10,500 structures and the lives of at least 31 people. (iii)

Wildfires in recent years

Wildfires continue to damage properties and burn through millions of acres each year, with 2020 seeing more wildfires and acres burned than ever before, according to the NIFC:

• 2021: 58,985 fires affecting 7,100,000 acres
• 2020: 58,950 fires affecting 10,122,336 acres

How much does the US spend to suppress wildfires?

The National Interagency Fire Center offers data on annual suppression costs for U.S. wildfires. The five-year average costs the Forest Service almost $2 billion, while the cost to DOI agencies was more than $453 million. The total ten-year average is less, at $1.91 billion, suggesting that the cost of suppressing these fires is going up over time. At $2.274 billion, 2020 was the most expensive year since 2018, when the total costs topped $3.143 billion.
