California’s Wildfires: Why Have They Been So Destructive?

All of this is happening in a region where more people are building homes tucked into forests.What lit these fires in the first place?Officials are not sure yet.There were 17 major fires burning in the state on Wednesday, and the specific cause of each fire will be investigated, according to Thom Porter, Southern California region chief at the state’s fire agency.In general, the vast majority of wildfires are caused by people, Mr. Porter said, and the past few months have been so dry that even seemingly innocuous human activities — a boat-trailer chain dragging on a road, engine heat coming off a car parked in a grassy area — have lit fires. It is possible, he said, that similar things may have started some of the current fires.Daniel Berlant, assistant deputy director of Cal Fire, the state firefighting agency, said there were no thunderstorms in the region when the fires started, so lightning has been all but ruled out as a cause.Could it have been downed power lines?State officials are looking into that possibility. There were some reports of sparking power lines and other electrical equipment problems over the weekend. And poor power-line maintenance by the main utility in Northern California, the Pacific Gas & Electric Company, has been blamed for some past wildfires.“Power lines are definitely one of the causes we’re looking into,” Mr. Berlant said, adding, “One thing we’ll be looking at is whether the fires started before the lines went down, or after.”VideoHow It Happens | Forest FiresFuel, oxygen and heat combine to start wildfires, which destroy millions of acres each year in the United States.By Aaron Byrd, David Frank and Henry Fountain on Publish Date May 15, 2014.Photo by Mike Blake/Reuters.Watch in Times Video »embed Ari Vanrenen, a spokeswoman for the utility, acknowledged that electric lines were down in the region, but said it was too early to say whether they could have sparked the fire.Continue reading the main storyIn 2015, a pine tree in the Sierra Nevada mountains came into contact with a 12-kilovolt conductor and burst into flames, leading to a fire that killed two people, destroyed 550 homes and scorched 70,000 acres, the state Public Utilities Commission concluded. It fined the utility company $8.3 million in April for failing to properly clear vegetation around the power line.What’s the role of climate change here?Fire seasons in general have grown longer and more destructive in recent decades, something scientists attribute in part to increased dryness caused by warming temperatures.

California Fires Burn Out of Control; 17 Are Dead

How Big Banks Are Putting Rain Forests in Peril

Originally posted here: How Big Banks Are Putting Rain Forests in Peril

102 million dead trees in California since 2010 will make for one helluva wildfire season.

Sixty-two million trees perished in the state in the last year alone, mostly in the Sierra Nevada, according to the U.S. Forest Service. That’s a lot of kindling.

Trees killed by rising temperatures, pests, and sustained drought “elevate the risk of wildfire,” said Agriculture Secretary Tom Vilsack. Oh goody: just what California needs!

The state this year saw its most expensive wildfire in history: Monterey County’s Soberanes Fire took out more than 132,000 acres, and cost more than $260 million. South of Monterey, San Bernardino’s Blue Cut Fire burned more than 36,000 acres, and destroyed nearly 100 homes.

Removing the kindling before it burns is not a silver bullet, according to environmental scientist Char Miller in the Los Angeles Times.

Even if foresters had unlimited funds, it would be unwise to remove all the dead trees. Charred, decomposing trees are a natural element of the landscape and can support other life, making forests healthier in the long run.

Western fires in general are now bigger, and fire seasons last longer than they did a few decades ago, due to extended drought and elevated temperatures.

Bracing For Fire

By Rodman Linn A photo from space of the Las Conchas fire in the Jemez mountains near Los Alamos, N.M. just after its start at 1:30 p.m. on June 26, 2011. On the first day, driven by strong and unpredictable winds, the fire burned 43,000 acres–a rate of about an acre per second. By the time the fire was controlled, it had burned more than 150,000 acres. (Photo courtesy of NASA.) How Computer Modeling Might Help Us Better Understand–and Better Manage–Wildfires This summer, throughout the West, higher temperatures and decreased precipitation brought on by climate change have ramped up the frequency of wildfires — big, catastrophic fires — while a century of fire suppression feeds the flames with a thick tangle of fuel in our overgrown forests. We can’t stop all fires — and we shouldn’t […]
