The United States endured $101.4 billion in weather and climate disaster losses through June 2025, according to new data from Climate Central. Fourteen (14) separate billion-dollar events were recorded, resulting in 174 deaths. This puts 2025 on track to be one of the most expensive years for natural catastrophe losses in recent history, intensifying pressure on the insurance industry to adapt to the growing risks of extreme weather.
The $101.4 billion in losses recorded in the first half of 2025 far exceeds the average pace of billion-dollar disasters in previous years. Since 1980, the US has experienced 417 weather and climate events with losses exceeding $1 billion each (CPI-adjusted to 2025 dollars), for a cumulative total of more than $3.1 trillion in damages and 17,092 deaths. The frequency and cost of these events have accelerated, with the last decade (2016–2025) standing out as particularly severe compared to earlier periods.
For insurers, the surge in billion-dollar disasters means a higher volume of claims and greater exposure to catastrophic losses. The report notes that both insured and uninsured direct losses are included in the $101.4 billion figure, covering property damage, business interruption, and infrastructure impacts. However, the Climate Central estimates do not account for environmental degradation, health costs, or supply chain disruptions, suggesting that the true economic toll is even higher.
The insurance sector must also contend with increased risk as development continues in vulnerable areas such as coasts, floodplains, and the wildland-urban interface. Inadequate building codes and insufficient mitigation measures further heighten vulnerability, making it more difficult for insurers to accurately price risk and maintain coverage availability.
The 2010–2019 decade was already far costlier than previous decades, and the trend has continued into the 2020s. Climate Central’s analysis underscores that the rising number and cost of billion-dollar disasters are driven by a combination of increased exposure (more assets at risk), vulnerability (how much damage a hazard causes), and changes in the frequency and intensity of extreme weather events. Notably, the report highlights the growing risk of drought, longer wildfire seasons in western states, and more frequent extreme rainfall in the east.
The billion-dollar disaster dataset, now managed by Climate Central after a transition from NOAA’s National Centers for Environmental Information (NCEI), is built on a peer-reviewed methodology. The analysis draws from more than a dozen public and private sources, including FEMA, the USDA, the National Interagency Fire Center, and insurance industry data. The methodology has been refined to address potential biases, but the current approach is still believed to underestimate average losses by 10–15%. As a result, the reported figures should be considered conservative.
Several additional potential billion-dollar events from 2025 - including severe storms and flooding in the Southeast, Central Texas, and the North Central US - are still under review. If confirmed, these could push the year’s total even higher, further challenging insurers, policymakers, and communities to manage the escalating risks.
As the insurance industry grapples with the mounting costs and complexity of extreme weather, robust data and transparent reporting remain critical for risk assessment, pricing, and resilience planning. Climate Central’s stewardship of the billion-dollar disaster database provides a vital resource for understanding and managing the nation’s evolving climate risks. The report emphasizes that disaster impacts result from a combination of increased risk and climate variability, and that effective mitigation and adaptation strategies will be essential for the insurance sector and society at large.
