Authorities have said that the fire, dubbed the Clayton fire, is the direct result of the actions of a onetime [inmate firefighter](http://www.latimes.com/local/lanow/la-me-ln-clayton-fire-20160816-snap-story.html) who now faces 11 counts of arson. Arson ranks as the most obvious in a long list of the ways that humans cause and worsen wildfires, making them disasters that are less than natural. Nine out of 10 wildfires are the direct result of human activity, a long list that includes poorly attended camp fires, discarded cigarette butts and equipment use. More than 2.4 million acres burn each year as a result of human-caused fires, according to a National Interagency Fire Center [report](https://www.nifc.gov/fireInfo/fireInfo%5Fstats%5Flightng.html). Human-caused global warming has also contributed to more frequent and severe wildfires, scientists say. Warm weather and a lack of water kills trees, creating kindling for fires, and heat increases the length of the wildfire season. And, because temperatures tend to be [hotter and drier](http://time.com/3849320/california-drought-wildfires/) than in previous generations, firefighters often struggle to put out blazes. The length of fire season increased by 19% between 1979 and 2013, according to recent [research](http://time.com/3959260/climate-change-wildfires/), as temperatures have spiked due to climate change. ### See Inside the Blue Cut Fire’s Explosive Growth and Devastation  A firefighter keeps an eye on the Blue Cut fire line, north of Los Angeles, Calif, Aug. 16, 2016.

Ringo Chiu—AFP/Getty Images Not all wildfires have human fingerprints on them and the phenomenon can actually improve the health of forests by clearing debris and nourishing the soil, functions wildfires have carried out for ages. But officials estimate that only 10% of wildfires have natural causes, almost entirely lighting strikes. The cause is not yet known for the[ latest wildfire to hit California](http://time.com/4456109/blue-cut-fire-southern-california-photos/), a fast-moving blaze that had engulfed nearly 47 square miles in the southern part of the state by Wednesday. Wildfires often rank among the most devastating natural disasters in the U.S. Last year, more than 10 million acres burned across the country, at a cost of more than $1 billion to the federal government. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4456011/california-wildfires-natural-disasters/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4456011/california-wildfires-natural-disasters/"},"headline":"Don’t Call the California Wildfires ‘Natural Disasters’","datePublished":"2016-08-17T22:00:35.000Z","dateModified":"2026-05-11T04:59:35.815Z","description":"Humans deserve most of the blame for the spike wildfires","url":"https://time.com/4456011/california-wildfires-natural-disasters/","keywords":["Wildfires","Natural Disasters"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltf8f284f266c7433a/6988a2bf97cdff75ac6ad7af/california-wildfires-natural-disasters.jpeg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Justin Worland","jobTitle":"Senior Correspondent","url":"https://time.com/author/justin-worland/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltf8f284f266c7433a/6988a2bf97cdff75ac6ad7af/california-wildfires-natural-disasters.jpeg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"california wildfires natural disasters","caption":"california wildfires natural disasters","creditText":"Gabrielle Lurie_AFP/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/wildfires/","name":"Wildfires"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4456011/california-wildfires-natural-disasters/","name":"Don’t Call the California Wildfires ‘Natural Disasters’"}}]}] ```
