U.S. Climate Disasters Have Cost Nearly $1 Trillion This Decade

The U.S. is on track to record nearly $1 trillion in climate disaster losses this decade alone. Just six years into the 2020s, the cost of climate-driven natural disasters like tropical cyclones and droughts has already approached the total seen over the entire 2010s.

This visualization, created in partnership with Inigo, shows how the financial impact of climate events has escalated since 1980.

The Rising Cost of Climate-Related Natural Disasters

In the 1980s, the first decade with strong records of billion-dollar disasters, costs amounted to $227 billion in total. At that time, droughts made up over half of the costs.

Time Period	Tropical Cyclone Cost	Severe Storm Cost	Wildfire Cost	Drought Cost	Other Cost	Decade Total
1980s	$48B	$13B	-	$122B	$44B	$227B
1990s	$130B	$43B	$14B	$28B	$131B	$347B
2000s	$451B	$73B	$21B	$70B	$28B	$643B
2010s	$554B	$207B	$73B	$100B	$95B	$1T
2020s	$412B	$252B	$106B	$65B	$66B	$901B

Source: Climate Central. Costs adjusted for inflation. Data for the 2020s is as of March 2026, with the mid-March Hawaii flooding and February Northeast winter storm still being assessed. Costs by climate event may not sum to the decade total due to rounding.

With each passing decade, the inflation-adjusted cost of natural disasters has increased significantly. The 2000s saw the biggest jump, with costs rising by 85% compared to the 1990s. Tropical cyclones also accounted for over two-thirds of costs, with Hurricane Katrina alone costing $208 billion.

Ever since, tropical cyclones have accounted for the bulk of losses. In the 2010s, total losses reached $1 trillion. And, in the 2020s, costs have nearly reached this same milestone despite there still being more than three years left in the decade.

Hurricane Ian in September 2022 has been the most costly disaster of the decade so far, causing $123 billion in damage. In fact, Ian ranks as one of the most powerful U.S. hurricanes since 1900.

Wildfires have also been a significant contributor to costs, amounting to over $100 billion in losses so far in the 2020s.

The Frequency of Climate-Driven Natural Disasters

On top of rising costs, climate disasters are also becoming more frequent. While there were just 33 billion-dollar disasters in the 1980s, that number has steadily climbed.

So far, the 2020s have set a record with 143 billion-dollar natural disasters that were climate driven.

What It Means for Assessing Climate Risk

As climate events become more frequent and costly, past losses are an increasingly irrelevant predictor of risk for companies and insurers.

Moving forward, insurers can take actions to manage their risk:

Watch total exposure: Understand how multiple events can hit at once rather than looking at single risks in isolation.
Look forward: Rely less on past losses and more on what future climate risk could look like.
Build flexible coverage: Use retention, structures, and limits that can absorb uncertainty.
Reward resilience: Focus on how well a business is prepared rather than only where it’s located.
Be clear about risk appetite: Clearly define where you will—and won’t—take on risk.

Climate losses are outpacing traditional underwriting cycles, putting pressure on how quickly risk is priced and transferred.
