Deadly wildfires spark debate about development

USA — FRESNO – A speeding wildfire in California that turned hundreds of homes near Lake Isabella to piles of twisted rubble has forced a conversation about how to minimize destruction in the most populous state experiencing the effects of climate change.

Wildfires in the last years have killed several people in the state, a drought-prone state experiencing a five-year dry spell.

Weather is one factor, but more critical is the state’s exploding population, spawning communities in the once sparsely inhabited ranch and timberland regions long known to burn, experts say.

“We know this is going to happen,” said Kevin Ryan, a former U.S. Forest Service fire scientist, now a consultant with FireTree Wildland Fire Sciences. “We need to manage to take the crisis out of it.”

Judy and Ken Brown were among hundreds who narrowly escaped the firestorm last week that swept down a mountainside and through their community beside Lake Isabella, an hour east of Bakersfield.

They’ve seen wildfires in the past, but none like this one that quickly consumed their mobile home and dozens in the neighborhood largely made up of retirees.

Judy Brown said she and her husband received an automated call telling them to leave. They soon heard exploding propane tanks and neighbors screaming.

With their two dogs loaded in their car, the couple drove to safety through thick smoke as their home burned behind them. Judy Brown said they were lucky to survive.

“It was like a tornado, but it was fire,” she said. “I thought it was the end of the world.”

The fire, driven by strong winds across mountains covered with dry grass and trees, travelled 11 miles in its first 13 hours, which firefighters say is fast. It killed and elderly couple and destroyed more than 200 homes.

California’s wildfire season typically starts in August, raising concerns about the June fire at Lake Isabella sparking so early.

It also follows 2015’s voracious wildfire season marked by six deaths. Four people died in a Lake County fire north of San Francisco that destroyed 1,300 homes. A fire in Amador and Calaveras counties destroyed more than 800 buildings and killed two people. Both fires rapidly spread.

Climate change will continue to make wildfires more severe throughout the western states, including California, according to a report by the Climate Central, a nonprofit organization of scientists.

An estimated 11 million Californians live in areas with a high risk of wildfire, the report says, and by 2050 California’s wildfire season is expected to increase from 120 days to 144 days.

Bill Patzert, a climatologist at NASA’s Jet Propulsion Laboratory, says changing weather patterns are one factor. Winter temperatures have risen 2 to 3 degrees in the last century, he said, and California’s snowpack is more fleeting. Millions of trees in the Sierra Nevada have died in drought.

The weather, however, is not solely to blame for the highly destructive wildfires, said Patzert, who blames poor planning that allowed communities to be built in risky places.

“Putting it all in the climate change bin is like throwing in the towel,” Patzert said. “Let’s not forget a lot of it is our misbehavior and our decisions how we zone and where we zone.”

The areas throughout California, where cattle grazed and loggers harvested trees, have given way to subdivisions of homes in the last 50 years, said Bill Stewart, co-director of the Center for Fire Research and Outreach at the University of California, Berkeley.

Residents in these places must be aware of the danger, and not rely on the local fire department to tell them when to clear the grass and trees that could easily spread fire to their homes, he said.

“That’s the issue – more people living right next to wildland,” Stewart said of the wildfire near Lake Isabella. “If no one lived there, this wouldn’t have been a big story.”
