Climate-related conditions such as low snowpack, wildfire smoke, drought, and flooding are becoming more common across Colorado and the Western United States. While these events may appear temporary, they are influencing housing markets, insurance costs, and broader economic behavior.
Ryan C. Lewis, associate professor of finance at the Leeds School of Business, studies how climate risks affect housing, insurance, and investment decisions. His research highlights both immediate disruptions and longer-term shifts tied to these risks.
Immediate and Long-Term Economic Effects
Climate events affect local economies through two primary channels. First, there are direct impacts. Disasters disrupt business activity, damage infrastructure and housing, and slow or halt operations. For example, drought conditions can limit agricultural output and increase water costs, while low-snow winters reduce ski activity.
Second, longer-term effects can persist even after the initial event ends. Research on wildfires shows that areas exposed to smoke, even without direct damage, experience lasting behavioral changes. People reduce outdoor activity, and over time, firms are more likely to exit while investment declines. Expectations about future conditions appear to influence these patterns.
Housing Markets and Climate Risk
Housing markets show some signs of incorporating climate risk, although measuring these effects remains complex. Climate risks often affect large regions and involve uncertainty, making direct comparisons between properties difficult.
Sea level rise offers a clearer example. Research comparing similar homes with different long-term exposure found that properties facing higher future risk sold at a discount. That discount increased over time, particularly after 2012 when public awareness of climate risk grew.
Other risks, such as wildfire and drought, are harder to isolate. Wildfire exposure can vary significantly between properties, and homes near wildland areas often differ from those in urban settings in other ways. While pricing effects may be emerging, they are more difficult to quantify.
Rising Insurance Costs and Market Behavior
Insurance costs have increased, with climate risk identified as a major contributing factor alongside inflation and improved risk assessment. Higher disaster risk is contributing to upward pressure on premiums.
These rising costs influence housing markets in two ways. First, higher insurance premiums increase the total cost of homeownership, which can reduce buyers’ willingness to pay. Second, increased premiums appear to shift buyer behavior.
Research on flood insurance subsidies found that when subsidies were removed and premiums increased, property values declined more for homes exposed to future risk rather than just current risk. This suggests that higher insurance costs prompt buyers to consider long-term exposure more closely.
Broader Consumer and Market Adjustments
Climate risks also affect broader consumer behavior. As certain locations experience more frequent disruptions, such as reduced snowfall or increased smoke, they may become less attractive and more expensive to maintain.
Over time, individuals and markets adapt. People may relocate, adjust travel patterns, or invest in infrastructure. For instance, changes in ski conditions could influence travel or migration patterns toward areas with more consistent snowfall.
Adaptation also occurs at a smaller scale. The widespread adoption of air conditioning has reduced heat-related mortality, demonstrating how infrastructure investments can mitigate some risks.
Tools and Uncertainty in Risk Assessment
Consumers and market participants now have access to tools that provide projections for flood, fire, and heat risks at specific locations. These tools offer both current and future risk estimates.
However, uncertainty remains a key factor. Many models present a wide range of possible outcomes. For example, projections for snowpack in Colorado may show stable averages, but individual models can vary significantly, with some predicting declines and others increases. Understanding this range of outcomes is important for decision-making.
Potential Changes in Risk Markets
Market structures related to climate risks may continue to evolve. In the United States, systems for trading resources such as water remain relatively inflexible due to regulatory constraints.
More flexible markets for water, insurance, and other climate-related risks could improve resource allocation. For example, increased demand for artificial snow could lead to changes in how water is accessed and distributed.
Climate-related insurance markets may also expand to address risks tied to water and other exposures. While these markets require careful design, they could help manage short-term disruptions and support longer-term planning.
