LOS ANGELES, USA (AFP) — California is battling its third-largest wildfire since 1932, and winds and dry conditions may help the blaze grow even further, the California Department of Forestry and Fire Protection said yesterday.

The so-called Thomas fire has burned 259,000 acres (105,000 hectares) of land, destroyed over 1,000 structures and cost more than $100 million since it broke out on December 4, and conditions including winds, dry fuel and low humidity “will continue to support fire growth”, Cal Fire said.

More than 8,000 people are involved in battling the blaze.

Only two fires have burned more acreage in California so far this century: the Cedar Fire of 2003, and the Rush Fire of 2012, which scorched 273,246 and 271,911, respectively.

Cal Fire’s list of the top 20 largest wildfires in the state dates back to 1932, as earlier records “are less reliable, and this list is meant to give an overview of the large fires in more recent times,” it says.

The Santiago Canyon Fire of 1889 reportedly burned 300,000 acres, which would put it atop Cal Fire’s list.

A series of fires broke out in California this month, most of which have since been contained.

The Thomas fire is the only one to have resulted in deaths.

San Diego-based Cal Fire engineer Cory Iverson died fighting the Thomas fire in Ventura County, while a 70-year-old woman was killed in an accident as she fled in her car.

This year is the worst on record for wildfire devastation in California.

California governor Jerry Brown has said that the wildfires ravaging his state should serve as a warning to parts of the world threatened by climate change.

“The important fact is that these fires are going to become a very frequent occurrence. That’s what the science is telling us,” Brown said.

“It’s a real indicator of bad things to come, and hopefully will serve to wake up people who right now are too complacent,” he said.
