Americans Are Moving Into Fire-Prone Regions Despite Escalating Climate Risks
Rising migration toward wildfire-prone and heat-stressed areas is intensifying climate-related risks for communities across the United States.
Americans Are Flocking to Fire-Prone and Heat-Stressed Regions
Over the past decade, a surprising demographic shift has taken place: Americans are leaving many regions afflicted by hurricanes and heatwaves and migrating toward areas with a greater risk of wildfires and higher average temperatures. According to one of the largest and most comprehensive studies on U.S. migration and natural disasters, published in Frontiers in Human Dynamics, this shift is alarming for public health and safety: The very places Americans are choosing to settle are those projected to experience worsening wildfire seasons and rising heat, fueled by climate change.
Key Findings from Migration Studies
- Top migration destinations: Cities and suburbs in the Pacific Northwest; parts of the Southwest such as Arizona, Colorado, Nevada, Utah; Texas; Florida; and a broad stretch of the Southeast (including Nashville, Atlanta, and Washington, D.C.).
- Areas losing population: The Midwest, Great Plains, and regions along the Mississippi River, many of which have been hit hardest by hurricanes or frequent, intense heatwaves.
This population movement is deeply concerning, as it places more people in harm’s way, particularly with respect to wildfire risk and extreme heat—two hazards projected to intensify as the climate continues to warm.
Escalating Wildfire and Heat Risks: A Climate Perspective
Wildfires across North America and globally are worsening due to a combination of rising temperatures, prolonged droughts, shifting land use patterns, and increasing human presence in fire-prone regions.
Boreal Forests: A Case Study in Rapid Fire Escalation
- More than 60% of all fire-related tree cover loss since 2001 has occurred in boreal forests.
- Fire-related tree loss in boreal zones has increased by about 160,100 hectares annually over the last 24 years.
- Examples include record-breaking wildfires in Russia (5.4 million hectares lost in 2021) and Canada (nearly 7.8 million hectares in 2023, sixfold the annual average for 2001–2022).
These trends are largely attributed to climate change, with northern latitudes warming faster than the global average and contributing to longer, drier fire seasons.
Fire Trends in Temperate and Subtropical Forests
- Temperate forests—including regions of the eastern United States, western Europe, and eastern Asia—are experiencing a fire increase of about 23,300 hectares per year.
- Subtropical regions (southeastern US, Australia, Mediterranean) have seen relatively stable fire rates, but still face considerable risks due to drought and heatwaves.
Heatwaves and land-use changes, such as increased urbanization and abandonment of former agricultural lands, compound these risks. For instance, the Mediterranean experienced its worst fire year since 2001 in Spain in 2022 due to prolonged drought and record-breaking heat.
Why Are People Moving Into More Dangerous Regions?
Despite the obvious and growing risks, many Americans continue to relocate to areas with elevated wildfire and heat threats. The reasons for this phenomenon are multifaceted and complex:
- Lifestyle preferences: Favorable climate, scenic landscapes, and outdoor recreation opportunities often attract new residents despite risks.
- Economic factors: Housing affordability and job availability, particularly in expanding urban and suburban centers, can outweigh environmental concerns.
- Lack of risk visibility: Real estate listings, like those on Zillow, rarely highlight heat or wildfire danger. Only recently have platforms like Redfin introduced risk scores for property listings.
- Novelty of risks: Many Americans still perceive wildfires as a primarily western problem, not recognizing risks in areas like the Northwest, Southwest, Appalachia, and parts of Florida.
What others are reading
Human Settlement Patterns Worsen Fire Risk
The expansion of residential and commercial developments into so-called wildland-urban interfaces (WUIs)—zones where built environments intermingle with forests and grasslands—significantly increases the likelihood, severity, and impacts of wildfires.
- Natural lands are rapidly converted to WUIs, increasing ignition risk, property damage, and loss of life.
- In 2022, wildfires in the U.S. burned nearly 1 million hectares of forest and caused approximately $3.3 billion in damages.
- Large fires, such as California’s Mosquito Fire, have devastated wildland-urban zones.
As more people move into zones with intersecting environmental and climate hazards, the complexity and cost of managing disaster risk escalates.
Forest Management and Megafire Risks
Recent research has revealed that forest management practices, particularly on private, industrial lands, further increase wildfire risk. Managed forests tend to have dense stands, regularly spaced trees, and uninterrupted layers of vegetation—all conditions that favor megafires.
- The odds of high-severity wildfire are 1.5 times higher on industrial private land than on publicly managed forests.
- Dense, continuous vegetation connects the understory to the canopy, allowing fires to spread more rapidly.
- Thinning practices that reduce density are recommended to make forests more resilient to wildfire.
Implications for Urban Planning and Policy
The convergence of migration trends, climate change, and wildfire risk presents new challenges for city planners, policymakers, and citizens. According to the UVM study, urban planners must seriously consider discouraging new development in zones where fire risk is highest or where firefighting is particularly challenging.
- Risk-aware planning: Cities and counties should integrate wildfire and climate risk assessments into zoning and development decisions.
- Fire prevention strategies: Community preparedness, controlled burning, and forest thinning can help reduce the potential for catastrophic fires.
- Public awareness campaigns: Education efforts can inform residents about local risks, preparedness, and mitigation measures.
- Policy reforms: Building codes, land management regulations, and insurance frameworks may need strengthening to reduce vulnerability.
With the growing economic toll—multi-billion-dollar disasters and mounting recovery costs—these policy shifts are becoming more urgent.
How Climate Change Amplifies Fire and Heat Hazards
Wildfire and heat risk are no longer isolated problems; they are systemic issues affecting multiple regions of the U.S. and beyond:
- Extreme weather—including droughts, prolonged heatwaves, and intense storms—is becoming more frequent and severe as global temperatures rise.
- Prolonged droughts and high temperatures create prime conditions for ignition and rapid fire spread.
- Vegetation growth in abandoned or mismanaged lands increases fuel for fires.
- Land-use changes, such as expansion of flammable plantations and continuous underbrush, heighten regional risks.,
Notably, the increase in heat and fire risk can result in a “tipping point” effect—where the hazards of living in a high-risk zone begin to outweigh perceived benefits, as has occurred in many hurricane-prone areas.
Challenges for Public Health and Safety
The trend of migration into hazard-prone regions carries significant implications for public health, safety, and long-term sustainability:
- Greater population exposure leads to increased injuries, fatalities, and displacement.
- Property losses rise sharply, driving up insurance costs and hindering economic stability.
- Healthcare systems face strain from smoke inhalation, heat stress, and related emergencies.
- Vulnerable groups—such as children, seniors, and lower-income households—are disproportionately affected.
Mitigation and Adaptation: Pathways Forward
To address the mounting risks, communities and governments must adopt a multifaceted approach, combining immediate mitigation with long-term adaptation.
Mitigation Strategies
- Forest thinning and controlled burns to reduce fuel loads.
- Improved land management practices, especially in wildland-urban interfaces.
- Development of community evacuation plans and emergency response systems.
- Investment in resilient infrastructure and building codes.
Adaptation Approaches
- Strategic retreat and incentivized relocation out of the highest-risk zones.
- Publicly accessible hazard mapping tools and transparent risk disclosure in home sales and rentals.
- Community education, collaboration, and inclusion in decision-making processes.
