Investigators are trying to determine what caused several wind-driven wildfires that have destroyed thousands of homes across the Los Angeles area in January 2025. Given the fires’ locations, and lack of lightning at the time, it’s likely that utility infrastructure, other equipment or human activities were involved.
California’s wildfires have become increasingly destructive in recent years. Research my colleagues and I have conducted shows U.S. wildfires are up to four times larger and three times more frequent than they were in the 1980s and ’90s. Fast-moving fires have been particularly destructive, accounting for 78% of structures destroyed and 61% of suppression costs between 2001 and 2020.
Lightning strikes are a common cause of U.S. wildfires, but the majority of wildfires that threaten communities are started by human activities.
What makes these wildfires so destructive and difficult to contain?
The answer lies in a mix of wind speed, changing climate, the legacy of past land-management practices, and current human activities that are reshaping fire behavior and increasing the risk they pose.

Fire’s perfect storm
Wildfires rely on three key elements to spread: conducive weather, dry fuel and an ignition source. Each of these factors has undergone pronounced changes in recent decades. While climate change sets the stage for larger and more intense fires, humans are actively fanning the flames.
Climate and weather
Extreme temperatures play a dangerous role in wildfires. Heat dries out vegetation, making it more flammable. Under these conditions, wildfires ignite more easily, spread faster and burn with greater intensity. In the western U.S., aridity attributed to climate change has doubled the amount of forestland that has burned since 1984.
Compounding the problem is the rapid rise in nighttime temperatures, now increasing faster than daytime temperatures. Nights, which used to offer a reprieve with cooler conditions and higher humidity, do so less often, allowing fires to continue raging without pause.
Finally, winds contribute to the rapid expansion, increased intensity and erratic behavior of wildfires. Wind gusts push heat and embers ahead of the fire front and can cause it to rapidly expand. They can also create spot fires in new locations. Additionally, winds enhance combustion by supplying more oxygen, which can make the fire more unpredictable and challenging to control. Usually driven by high winds, fast-moving fires have become more frequent in recent decades.

Fuel
Fire is a natural process that has shaped ecosystems for over 420 million years. Indigenous people historically used controlled burns to manage landscapes and reduce fuel buildup. However, a century of fire suppression has allowed vast areas to accumulate dense fuels, priming them for larger and more intense wildfires.
Additionally, human development in fire-prone regions, especially in the wildland-urban interface, where neighborhoods intermingle with forest and grassland vegetation, has introduced new, highly flammable fuels. Buildings, vehicles and infrastructure often ignite easily and burn hotter and faster than natural vegetation. These changes have significantly altered fuel patterns, creating conditions conducive to more severe and harder-to-control wildfires.

Lightning-started fires often coincide with storms that carry rain or higher humidity, which slows fires’ spread. Human-started fires, however, typically ignite under more extreme conditions – hotter temperatures, lower humidity and stronger winds. This leads to greater flame heights, faster spread in the critical early days before crews can respond, and more severe ecosystem effects, such as killing more trees and degrading the soil.
Human-ignited fires often occur in or near populated areas, where flammable structures and vegetation create even more hazardous conditions. Homes and the materials around them, such as wooden fences and porches, can burn quickly and send burning embers airborne, further spreading the flames.
As urban development expands into wildlands, the probability of human-started fires and the property potentially exposed to fire increase, creating a feedback loop of escalating wildfire risk.

Whiplash weather
A phenomenon known as whiplash weather, marked by unusually wet winters and springs followed by extreme summer heat, was especially pronounced in Southern California in recent years.

A wet spring in 2024 fostered vegetation growth, which then dried out under scorching summer temperatures, turning into highly combustible fuel. This cycle fueled some of the biggest fires of the 2024 season, several of which were started by humans.
That dryness continued in Southern California through the fall and into early winter, with very little rainfall. Soil moisture in the Los Angeles region was about 2% of historical levels for that time of year when the fires began on Jan. 7, 2025.
As the factors that can drive wildfires converge, the potential for increasingly severe wildfires looms ever larger. Severe fires also release large amounts of carbon from trees, vegetation and soils into the atmosphere, increasing greenhouse gas emissions and exacerbating climate change, contributing to more extreme fire seasons.
Unmasking the Deception: The $300 Million Fraud Case Surrounding Arizona Athletic Grounds
Randy and Chad Miller face serious fraud charges after allegedly defrauding investors out of $300 million in their failed sports complex, revealing a cautionary tale for investors.

In a tale that intertwines ambition with deceit, the shocking story of Randy and Chad Miller, the father-son duo behind what was once touted as the largest sports and entertainment complex in the United States, has taken a dark turn. Opening the sprawling Bell Bank Park—which boasts an impressive 194 fields and courts—in East Mesa just three years ago, the Millers had big dreams. But now, they find themselves embroiled in a federal indictment that claims they defrauded investors out of nearly $300 million.
A Grand Vision Becomes a Nightmare
The original vision for the sports complex, which has since been rebranded as Arizona Athletic Grounds, was ambitious. Randy Miller, the mastermind behind the project, had long dreamed of creating a hub for sports and entertainment that would attract families, athletes, and fans from across the nation. After years of planning and investment, the facility finally opened its doors, seemingly fulfilling a lifelong dream.
However, dreams of grandeur have turned into a nightmare, as the Millers face serious allegations of using the facility as a front for an elaborate fraud scheme. With the company declaring bankruptcy in 2023—reporting debts of a staggering $366 million—investors and stakeholders are left reeling.
The Allegations: A Web of Fraud and Deceit
According to the federal indictment, Randy and Chad Miller allegedly enriched themselves at the expense of investors, using funds raised from municipal bonds for personal luxuries rather than for the intended purpose of constructing and operating the sports complex. The FBI claims they employed fraudulent documents and misrepresented the financial viability of the project to lure in unsuspecting investors.
From lavish purchases of luxury vehicles to alleged misappropriation of funds for personal expenses, their actions paint a picture of greed and entitlement. Not only did the Millers reportedly pay themselves significantly beyond disclosed salaries, but they also misled investors with false financial projections and forged documentation purporting to show interest from customers.
A Cautionary Tale for Investors
This case serves as a cautionary tale about the complexities of investing in large-scale projects. The Millers poured their aspirations into the Arizona Athletic Grounds but masked disappointing financial realities with misleading projections and falsified documents. The initial feasibility study performed in 2016 indicated the project would generate significantly lower revenues than anticipated—a warning sign that went ignored in pursuit of ambition.
In a staggering twist, the project opened to a far cry from its projected success, generating less than $28 million in its first year compared to the nearly $96 million touted to investors. With bankruptcy filings showing that investors recouped a paltry sum of less than $2.5 million from their $284 million investment, many are left to ponder how their trust could be so easily manipulated.
Legal Ramifications and Future Implications
As the case unfolds, Randy and Chad Miller are facing severe legal consequences, including charges for wire fraud, securities fraud, and aggravated identity theft. If convicted, they could spend decades in prison, a sobering reality for the once-celebrated entrepreneurs. The U.S. Securities and Exchange Commission is also pursuing parallel action, further complicating matters for the Millers.

This incident not only reflects the pitfalls that entrepreneurs can face but also highlights the responsibilities of investors to conduct thorough due diligence before committing funds to any venture. The tale of the Millers serves as a stark reminder of the importance of integrity, transparency, and community trust in business practices.
Conclusion
As this saga continues to unfold, the story of the Arizona Athletic Grounds serves as a reflection on ambition gone awry. It’s a stark reminder that behind every grand vision lies the essential need for honesty and ethical conduct. The community of East Mesa, once hopeful for a thriving sports destination, now faces the challenge of moving forward, learning from the past, and rebuilding trust in local business ventures. We can only hope that the lessons from this cautionary tale resonate not just within the realm of sports and entertainment but across all industries that forge the backbone of our economy.

Los Angeles: Exciting developments are underway for Southern California drivers as the Metro initiates the I-105 ExpressLanes Project, aimed at easing traffic congestion and enhancing roadway safety. As one of the region’s major arteries, the I-105 has long been burdened by heavy traffic, and Metro’s innovative approach promises to transform the existing landscape for the better.
What’s Happening?
The I-105 ExpressLanes Project is set to convert the existing High Occupancy Vehicle (HOV) lane, commonly known as the carpool lane, into not one, but two Metro ExpressLanes in each direction along the I-105. This enhancement is part of Phase 1 of the project, specifically Segment 1, which stretches between Sepulveda Boulevard and Central Avenue. This phase is anticipated to last approximately three years, during which significant improvements will be made.
As part of the construction process, crews will be actively engaged in demolishing and reconstructing several sound walls, as well as performing crucial roadway pavement construction along the corridor in Segment 1. These sound wall adjustments are needed to facilitate the necessary roadway upgrades and ensure a smoother driving experience.
Where Is All This Happening?
The primary work will take place along the existing sound wall area on Westbound I-105, specifically located between Domingues Channel and the Crenshaw Boulevard on-ramp. This location is critical, as it serves as a vital section of the highway that many rely on daily.
What Can You Expect During Construction?
Navigating through construction zones can sometimes be tricky, but here’s what you can expect during this project:
Access Points: Crews will enter the work area primarily from the freeway, meaning minimal disruptions to side streets.
Daytime Work Hours: Most of the construction activities will occur during daytime hours, making it easier for commuters to plan their travel. However, keep in mind that intermittent nighttime work may be necessary to perform certain activities safely, particularly those related to roadway pavement construction.
Landscape Restoration: Once the construction wraps up and improvements are complete, landscaping and any trees that have been removed will be restored, allowing the area to flourish once again.
Important Note on Scheduling
As with any large construction project, it’s crucial to understand that work activity is subject to change based on various factors, primarily weather conditions. Because construction can be dynamic, schedules may be adjusted according to the team’s assessments on-site.
In Conclusion
The I-105 ExpressLanes Project represents a forward-thinking solution to Southern California’s persistent traffic challenges. By converting the existing HOV lane into ExpressLanes, Metro is aiming not just to alleviate congestion, but to provide a safer and more efficient roadway experience for all. Keep an eye out for updates, stay informed, and plan your travel accordingly—we can look forward to a smoother ride on the I-105 in the years to come!

Workers who are in frequent contact with potentially sick animals are at high risk of bird flu infection.

Disease forecasts are like weather forecasts: We cannot predict the finer details of a particular outbreak or a particular storm, but we can often identify when these threats are emerging and prepare accordingly.
The viruses that cause avian influenza are potential threats to global health. Recent animal outbreaks from a subtype called H5N1 have been especially troubling to scientists. Although human infections from H5N1 have been relatively rare, there have been a little more than 900 known cases globally since 2003 – nearly 50% of these cases have been fatal – a mortality rate about 20 times higher than that of the 1918 flu pandemic. If the worst of these rare infections ever became common among people, the results could be devastating.
Approaching potential disease threats from an anthropological perspective, my colleagues and I recently published a book called “Emerging Infections: Three Epidemiological Transitions from Prehistory to the Present” to examine the ways human behaviors have shaped the evolution of infectious diseases, beginning with their first major emergence in the Neolithic period and continuing for 10,000 years to the present day.
Viewed from this deep time perspective, it becomes evident that H5N1 is displaying a common pattern of stepwise invasion from animal to human populations. Like many emerging viruses, H5N1 is making incremental evolutionary changes that could allow it to transmit between people. The periods between these evolutionary steps present opportunities to slow this process and possibly avert a global disaster.
Spillover and viral chatter
When a disease-causing pathogen such as a flu virus is already adapted to infect a particular animal species, it may eventually evolve the ability to infect a new species, such as humans, through a process called spillover.
Spillover is a tricky enterprise. To be successful, the pathogen must have the right set of molecular “keys” compatible with the host’s molecular “locks” so it can break in and out of host cells and hijack their replication machinery. Because these locks often vary between species, the pathogen may have to try many different keys before it can infect an entirely new host species. For instance, the keys a virus successfully uses to infect chickens and ducks may not work on cattle and humans. And because new keys can be made only through random mutation, the odds of obtaining all the right ones are very slim.
Given these evolutionary challenges, it is not surprising that pathogens often get stuck partway into the spillover process. A new variant of the pathogen might be transmissible from an animal only to a person who is either more susceptible due to preexisting illness or more likely to be infected because of extended exposure to the pathogen.
Even then, the pathogen might not be able to break out of its human host and transmit to another person. This is the current situation with H5N1. For the past year, there have been many animal outbreaks in a variety of wild and domestic animals, especially among birds and cattle. But there have also been a small number of human cases, most of which have occurred among poultry and dairy workers who worked closely with large numbers of infected animals.
Pathogen transmission can be modeled in three stages. In Stage 1, the pathogen can be transmitted only between nonhuman animals. In stage 2, the pathogen can also be transmitted to humans, but it is not yet adapted for human-to-human transmission. In Stage 3, the pathogen is fully capable of human-to-human transmission.Ron Barrett, CC BY-SA
Epidemiologists call this situation viral chatter: when human infections occur only in small, sporadic outbreaks that appear like the chattering signals of coded radio communications – tiny bursts of unclear information that may add up to a very ominous message. In the case of viral chatter, the message would be a human pandemic.
Sporadic, individual cases of H5N1 among people suggest that human-to-human transmission may likely occur at some point. But even so, no one knows how long or how many steps it would take for this to happen.
Influenza viruses evolve rapidly. This is partly because two or more flu varieties can infect the same host simultaneously, allowing them to reshuffle their genetic material with one another to produce entirely new varieties.
Genetic reshuffling – aka antigenic shift – between a highly pathogenic strain of avian influenza and a strain of human influenza could create a new strain that’s even more infectious among people.Eunsun Yoo/Biomolecules & Therapeutics, CC BY-NC
These reshuffling events are more likely to occur when there is a diverse range of host species. So it is particularly concerning that H5N1 is known to have infected at least 450 different animal species. It may not be long before the viral chatter gives way to larger human epidemics.
Reshaping the trajectory
The good news is that people can take basic measures to slow down the evolution of H5N1 and potentially reduce the lethality of avian influenza should it ever become a common human infection. But governments and businesses will need to act.
People can start by taking better care of food animals. The total weight of the world’s poultry is greater than all wild bird species combined. So it is not surprising that the geography of most H5N1 outbreaks track more closely with large-scale housing and international transfers of live poultry than with the nesting and migration patterns of wild aquatic birds. Reducing these agricultural practices could help curb the evolution and spread of H5N1.

People can also take better care of themselves. At the individual level, most people can vaccinate against the common, seasonal influenza viruses that circulate every year. At first glance this practice may not seem connected to the emergence of avian influenza. But in addition to preventing seasonal illness, vaccination against common human varieties of the virus will reduce the odds of it mixing with avian varieties and giving them the traits they need for human-to-human transmission.
At the population level, societies can work together to improve nutrition and sanitation in the world’s poorest populations. History has shown that better nutrition increases overall resistance to new infections, and better sanitation reduces how much and how often people are exposed to new pathogens. And in today’s interconnected world, the disease problems of any society will eventually spread to every society.
For more than 10,000 years, human behaviors have shaped the evolutionary trajectories of infectious diseases. Knowing this, people can reshape these trajectories for the better.Ron Barrett, Professor of Anthropology, Macalester College
