Climate change will make wildfires worse, even in areas that don’t have wildfires today

Yet another destination known for its skiing and snowy winters will be forced to contend with growing wildfire severity and frequency.

The Alps, Europe’s largest mountain range and a world-renowned skiing destination, and the Alpine Foreland, a deep trough in southern Germany at the edge of the Alps, have both enjoyed minimal wildfire danger thanks to abundant winter snowfall and temperate summer conditions. But that will change by 2040.

A study published in Natural Hazards and Earth System Sciences (NHESS) used climate models to forecast fire risk for the two locations and others from 1980 to 2099. Researcher Julia Miller used the Canadian Forest Fire Weather Index (FWI) as a fire danger indicator.

The research forecasted a likely increase in wildfire danger in temperate areas through the 21st century, with fire danger increasing to high even in regions where it is very low today. The results displayed a continual trend of worsening wildfire danger in the Alps and Alpine Foreland, with the climate change trend exceeding natural variability in the late 2040s. The excess would likely have happened earlier if not for the area’s current low wildfire danger.

These areas are expected to see what’s today considered a “100-year” fire event every 30 years by 2050 and every 10 years by the end of the century.

“Alterations in these variables are projected to more than double the frequency of occurrence of extreme fire weather until the end of the 21st century … and increase the duration, severity, and spatial extent of fires,” Miller said. “Due to climate change, fire weather and hence the likelihood of fire events are projected to increase in several regions of the world – including historically less fire-prone areas – in the future.”

A study posted on PreventionWeb indicates that fires in the Alps will increase because of growing intensity of drought periods and heat waves — and the increasing fire hazard resulting from rural abandonment and more recreational activities.

Alpine communities, such as the previously mentioned Canadian community of Whistler, may see this as a hard pill to swallow. The lack of historical fires in the area means local people also lack an established “culture” for living with fires, according to Switzerland’s University of Bern. Researchers there are currently working to identify the wildfire risk awareness of communities throughout the canton of Bern and determine the best approaches for specific groups in the area.

“Based on scientific findings, the project aims to develop optimized and/or new communication strategies and materials for implementation,” the university said. “These can promote behavioral changes regarding forest fire risks, thus helping to prevent such fires.”

Water system on the Tonto needs pre-season fire help

A longstanding wildfire safety collaboration between the Tonto National Forest and Arizona’s Gila County officials needs updating. The county began collaborating with the USFS and local fire districts back in 2006 when it installed 14 water tanks, bladders, and storage systems in helicopter-accessible areas on the forest. The intent, according to a recent Gila County Board of Supervisors meeting, was to put fires out as soon as they were detected in the Rim Country area near Payson. The water sites were positioned where helicopter turnaround time would be less than five minutes.

But those water systems are now falling apart. Gila County Emergency Services Coordinator Carl Melford told the Board of Supervisors that the average lifespan of a water bladder is five to seven years, and many of the sites have old bladders with deteriorating water storage tanks.

Melford hopes to use a $609,000 congressionally directed earmark grant through the USFS to fix the deteriorating system. The funds would have to be matched from Gila County for a total of $1.2 million.

“This funding provides the opportunity for the evaluation and purchase of new water tank storage systems to replace the dilapidated tanks and old bladders and to hire a qualified contractor to transport and install 56 tanks of 5000-gallon capacity at the 14 locations,” Melford said in his proposal to the board. “This will increase the capability of fire suppression efforts, which is vital to the protection of Gila County residents’ life and property in areas prone to wildfires.”

Bids for the project are due by May 14, just in time for what used to be the start of Arizona’s wildfire season from late April to the beginning of monsoon in June. That “season,” however, looks to mostly be a thing of the past as wildfires burn 100 days more than they did 50 years ago.

“We really don’t say we have a ‘fire season’ because we can have activity throughout the state year-round,” Arizona Department of Forestry and Fire Management spokesperson Tiffany Davila told the Arizona Republic last year. “We can see fire activity increase during the end of April, beginning of May.”

The Tonto National Forest’s most recent wildfire, the Valentine Fire, started on August 16 last year, nearly caused evacuations, and burned nearly 10,000 acres.

Humans are by far the main cause of wildfires

Every year in the U.S., billions of dollars are spent on wildfire suppression and risk reduction. The five federal fire agencies — Forest Service, Bureau of Land Management, National Park Service, Bureau of Indian Affairs, and Fish & Wildlife Service — spent a combined $4.4 billion (2021) and $3.5 billion (2022) in wildfire suppression alone, according to the National Interagency Fire Center (NIFC). The USFS announced in February that it would be investing nearly $500 million more in its “Confronting the Wildfire Crisis” 10-year strategy focusing on 21 priority landscapes across the West.

Despite the numerous projects and strategies billions in taxpayer monies have funded, one thing hasn’t changed over the past decade: Humans are still the main cause of wildfires — and numbers have worsened since 2014.

Air quality publication HouseFresh analyzed NIFC data from 2023 and ranked the causes of wildfires by number of occurrences. Of the recorded fires, 72.6 percent were directly caused by humans.

The bulk of last year’s wildfires were caused by debris burning and open burning, resulting in 1,302 wildfires. That is an increase from the 1,120 fires started by debris and open burning in 2022. Equipment and vehicle use, power generation/transmission/distribution, and arson were the next listed causes of wildfires in 2023 at 507, 390, and 364 respectively.

“The balance between human and natural fires has almost reversed since 2014, although the trend has not been smooth,” the HouseFresh report said. “The proportion of human-caused wildfires grew significantly in 2015, 2016 and 2020, peaking at 77.2 percent in 2020.”

To no one’s surprise, California leads the nation in number of acres burned by wildfires. The state totaled 344,878 acres burned, followed by Alaska at 295,105 acres and Arizona at 218,286 acres. Arizona led the nation, however, in the biggest increase in acres from 147,553 acres in 2022 to 218,286 acres in 2023. Southeast Fairbanks County in Alaska was the leading county in acres burned in 2023 at 141,399 acres.

“Alaska suffered the second-most land damage in 2023, despite the largest annual reduction in acres — down 2,818,744 acres from 3,113,849 in the previous, record-breaking year,” the report says. “Unfortunately, many places where fires burn are hard to reach; at the same time, permafrost and surface fuels make Alaska’s wildfires particularly pollutive.”

North America’s largest ski town prepares for wildfires

There’s only one way in and out of the Canadian municipality of Whistler.

The Coast Mountains surround the forested British Columbia town north of Vancouver, giving Whistler its world-renowned trait of being North America’s largest ski resort community. The rocky slopes, however, occasionally cause transportation problems for Whistler’s residents. Highway 99, the only passage through the southern parts of the mountain range, stands as residents’ only escape route during times of emergency.

The frequently suffocated roadway and recent devastating wildfires in the nearby communities of West Kelowna and Kelowna pushed the perennially  snow-focused municipality to begin serious planning for a potential fire disaster. Most Whistler neighborhoods are classified as “interface,” but the wildland and ornamental fuel load between residences have characteristics of an “intermix,” or homes being within a forest community. Because of this, Whistler scores high in the plan’s “overall fire risk” category.

Whistler’s pervasive forest primarily drove town officials to take a more proactive approach to wildfire defense in its creation of a community wildfire defense plan.

“Typically when a wildfire is approaching a community, these defense plans are done at the time as it’s approaching,” Whistler Fire Chief Thomas Doherty told Global News journalists for a recent article. “Obviously wildfire specialists will come in and assist with doing these neighborhood defense plans. We’ve done that in advance. We believe we’re one of the first municipalities to do this type of plan, to have this information readily available ahead of time.”

The approach Doherty references includes increasing FireSmart education for residents and visitors, changing municipal legislation and community planning with a wildfire resiliency focus, increasing interagency and firefighters’ wildfire response, and continuing strategic vegetation management efforts.

Resort Municipality of WhistlerGlobal News, in their conversation with Doherty, reports that one of the tools created from this plan includes 19 tactical sheets and GIS maps for various critical infrastructure and water source locations, identifying which neighborhoods have a one-way-in and one-way-out access, and safe zones for responders during times of emergency. All this information will reportedly be available to fire personnel through scannable QR codes.

“Extremely critical to have all this information done in advance,” Doherty said. “It’s just unfortunate when an event does occur. At least we’re that much more prepared. And we have all that information readily available.”

Texas hearings live

Here’s a tip from Michael Archer’s “Wildfire News of the Day”

ABC 7 in Amarillo is livestreaming the Texas House Committee that’s  investigating the deadly Panhandle wildfires; it resumes testimony today in Pampa.Before testimony began, Chairman Ken King, R-Canadian, said Osmose decided the company does not need to participate in the investigation. Osmose is a third-party contractor that inspects power poles for Xcel Energy. The company is named in some of the wildfire related lawsuits.

According to one of the lawsuits, the pole determined to be the ignition source of the Smokehouse Creek Fire should have been removed after it was inspected by Osmose earlier this year.

Day 2 of testimony in legislative hearings on deadly Panhandle wildfires:

One of the witnesses is explaining that without the many loads of water and retardant dumped on the Smokehouse Fire, his town would have completely burned to the ground. (Remember as you listen that the references to the “Forest Service” is not the federal USDA agency — it’s Texas A&M Forest Service.)

Here’s Day 1 of testimony, with a transcript:

USFS: Throwing money at fuels treatments won’t stop communities from burning

Large communities destroyed by wildfire has become a yearly occurrence as of late. Lahaina last year, Colorado communities in the 2021 Marshall Fire, Oregon communities in the 2020 Labor Day firestorms including the  Almeda Drive Fire, and Paradise, California — leveled by the 2018 Camp Fire — all these communities were devastated by wildfire.

And the economic cost is incalculable — the Denver Post reported last year that the Marshall Fire was Colorado’s costliest ever; it destroyed $2 billion in property and killed two people.
Colorado's Marshall Fire, December 2021 photoUSFS researchers are using the stories of these destroyed communities to try to find commonality — and possibly a solution to the growing threat of fast-spreading wildland/urban interface fires. Each of these fires was human-caused or ignited near or inside communities — and all of them occurred during extreme wind events — and they immediately overwhelmed both wildland and structural firefighting efforts. The most important, and arguably most overlooked, commonality is that none of the above fires were technically “wildfires” at all, but were “conflagrations,” or fires that spread past built barriers.

“These problem fires were defined as an issue of wildfires that involved houses,” researchers said. “In reality, they are urban fires initiated by wildfires. That’s an important distinction — and one that has big repercussions for how we prepare for future fires.”

… none of the above fires were technically “wildfires” at all, but were “conflagrations,” or fires that spread past built barriers.

The importance of the distinction laid out by the researchers lies in what people believe the solution might be. Recent federal investments in the Bipartisan Infrastructure Investment and Jobs Act and Inflation Reduction Act address fire risk and prioritize fuel treatments on public lands.

Environmental/Community conditios, urban fires

But fuels reduction on federal lands would not have prevented any of the above fires. As wildfire suppression costs have increased, so have disastrous interface fires. Most wildfires are started by humans on private lands, and those fires destroy a majority of western U.S. structures.

“Wildland fires do not per se encroach on communities,” the report says.  “Rather, it’s communities that have impinged on wildlands, where fires play an important ecological role.”

If the goal of wildfire management is to stop the destruction of human communities, then communities and local governments must accept that wildland fires are a necessary and inevitable ecological aspect of the land they are living on. The change in mindset from wildfire suppression to adaptive living will require a shift at all levels of society. But the destruction and long recovery aftermath of each of the burned communities mentioned above shows that the rewards may outweigh the risks.

Paradise aftermath

The California community of Paradise, leveled in 2018 by the Camp Fire, has been rebuilding partly with that idea in mind.

A few of the homes were rebuilt with a World War II-era military design, which is very resistant to ignition. The needed shift will take more than the transition of a few community homes, but it’s a start. Other changes, such as new construction siting, design, construction materials, and landscaping requirements will also need to be part of the new paradigm.

“We have to live with wildland fire, says the report. “We don’t have to live with fire in our communities.”
