Some areas see days of temperatures over 100F, drying plants and fueling wildfires as extreme heat creates deadly conditions

 

California experienced its hottest month on record in July as grueling heat baked the American west for weeks on end.

The state’s average temperature for the month was 81.7F (27.6C), according to the National Centers for Environmental Information, but some areas endured days of temperatures greater than 100F (about 38C). Several cities broke temperature records during a heatwave in early July – Palm Springs hit 124F on 5 July, while Redding in the state’s far north saw a high of 119F on 6 July.

Death Valley, the hottest place on Earth, recorded its hottest month ever in July, according to the National Park Service (NPS). In Nevada, Las Vegas reached 120F on 7 July, its hottest day in history, and set a record for number of days over 115F.

The impacts of extreme heat are being felt across the US and the world as the climate crisis drives increasingly severe and dangerous weather conditions. Last month about one-third of the US population was under warnings for record heat. The Earth saw its hottest day in recorded history on 22 July, breaking a record set just one day earlier.

Extreme heat poses major health risks and is the mostly deadly type of weather-related disaster. It is particularly dangerous for unhoused people and seniors as well as those who don’t have access to cooling spaces.

California’s high temperatures in July also helped dry out vegetation and fuel wildfires across the state. Late last month, the Park fire quickly exploded after an alleged arsonist sparked by the blaze in a city park by pushing a burning car into a ravine. The area had baked at temperatures 100F and above for days before and after the fire began. The Park fire has since become the fourth-largest blaze in state history.

 

The Pacific north-west has also endured intense heat and intense wildfires. Oregon has seen more land burned this year, more than 1.4m acres (567,000 hectares), than any year in the last 32 years, when the north-west interagency coordination center’s record-keeping began.

The extreme heat leads to more intense fires, and makes for challenging conditions for the firefighters responding to the incidents. Firefighters battling the Thompson fire last month, not far from where the Park fire broke out, suffered heat-related injuries.

Heatwaves are increasing in intensity and frequency, as well as duration and range, and are the weather events most directly impacted by the climate crisis, Dr Alexander Gershunov, a research meteorologist with the Scripps Institution of Oceanography, told the Guardian last month. He described heatwaves as “the weather extremes that are impacted by the steroids of climate change”.

“The trend is toward more frequent, more extreme, longer-lasting heatwaves all over the world,” he said. “California is certainly no exception.”

 Park fire scorches 386,000 acres as firefighters battle blazes across US west, including historic mining town of Havilah

The largest wildfire in the US swelled to more than 380,000 acres (154,000 hectares) on Tuesday morning, an area bigger than the city of Los Angeles and three times the surface area of Lake Tahoe, as thousands of firefighters battled the blaze in a remote wilderness area in northern California.

Meanwhile, the destruction caused by wildfires raging across the US west came into sharp focus as photographers documented the destruction left by the Borel fire in southern California. The fast-growing fire tore through the historic mining town of Havilah, leaving burnt buildings, cars and forests.

 

About 2,000 people were ordered to evacuate because of the fire, which burned through the Sequoia national forest. By Tuesday morning, the fire had torn through more than 57,000 acres (23,000 hectares) and was 17% contained.

No fatalities have been reported.

 In northern California, more than 5,500 firefighters were working to contain the Park fire, the largest wildfire in the state this year, which has moved up the ranks to become the fifth largest in the state’s recorded history.

By Tuesday afternoon, the fire had scorched more than 386,000 acres, according to the California department of forestry and fire (Cal Fire). It has destroyed more than 190 structures and is threatening 4,200 more.

After several days of intense firefighting efforts, crews had reached 14% of containment on Tuesday morning amid cooler temperatures and more humidity, but the fire continued to burn very actively, Cal Fire said. With the steep terrain, wind activity and many areas inaccessible to crews, the fire is making uphill runs and spot fires continue to occur, the agency said.

The massive fire continues to burn through rugged, inaccessible terrain with dense vegetation, threatening to spread to two other counties. “That’s going to be a continued challenge for us moving forward over the next couple of days,” said Mark Brunton, an operations section chief with Cal Fire.

Cooler weather has helped firefighters stop the blaze’s path near some communities like Forest Ranch, where some people began returning to unscathed homes on Tuesday.

Christopher and Anita Angeloni have lived in the community of 1,600 for 23 years, and have had to evacuate several times due to wildfires, including the 2018 Camp fire, which killed 85 people and decimated the nearby town of Paradise.

Christopher Angeloni said he constantly worked on creating defensible space around his home and was happy to return home nearly a week after evacuating to see his hard work paid off.

“We were prepared to possibly lose everything,” he said.

Anita Angeloni said it has been a stressful week. “We have not been sleeping enough, very tense, praying all the time, teary eyes,” she said. “But we’re here. We’ll see for how long.”

The man arrested on suspicion of starting the blaze by pushing a burning car into a gully made his first appearance in court on Monday and was charged with felony arson of an inhabited structure or property.

Ronnie Dean Stout was arrested at his home in Chico a day after the fire started. Prosecutors said Stout had a previous criminal record and would face life in prison if convicted.

The Butte county district attorney, Michael Ramsey, told reporters after the hearing that Stout said the incident was an accident, the Sacramento Bee reported.

 

The district attorney said during a press conference that Stout was seen drinking at a swimming hole in the area before the fire started and drove “recklessly” through the area before the car went over a berm. Witnesses reported hearing the sounds of an engine revving and scraping.

“The indication is he didn’t purposely light the car on fire because he was trying to get out of being stuck on the edge of a berm,” Ramsey said, according to KQED. “We have another witness who saw dirt and smoke coming up, then followed immediately by smoke. Then fire. There’s an extraordinary amount of dry grass.”

The Park and Borel fires are two of more than 100 blazes active in the US west. Evacuation orders were in effect on Monday on 25 wildfires, according to the National Interagency Fire Center. More than 27,000 wildland firefighters and support personnel are deployed.

Some blazes were sparked by the weather, with the climate crisis increasing the frequency of lightning strikes as the western US endures blistering heat and bone-dry conditions.

In Colorado, the Alexander Mountain fire doubled in size between Monday and Tuesday to more than 1,800 acres, according to the US Forest Service. The blaze, about 12 miles (19km) west of Loveland, Colorado, where the Rocky Mountains fold into the Great Plains, spurred mandatory evacuation orders and produced a looming column of smoke that could be seen for miles.

 

In Oregon, the 2024 wildfire season has burned more than 1.2m acres so far, according to the State of Oregon Fires and Hotspots Dashboard, a total that surpasses the size of the entire state of Rhode Island.

The state’s largest wildfire, the Durkee fire in Baker county, has burned nearly 300,000 acres and is more than 50% contained.

“Although yesterday’s rain was beneficial,” a Tuesday update from fire officials read, “it was not enough to extinguish heat on the fire.”
