Flood risk has worsened since 2020, with significant financial impacts from numerous disasters in the U.S. Severe weather patterns are rendering traditional flood risk projections unreliable. Research indicates a 67% increase in homes facing high flood risk over the next 30 years. A study predicts that by 2100, nearly 1.9 billion people globally will face increased flood exposure. There is a notable underestimation of risk among property owners, with many unaware of their vulnerability to flooding due to changing climate factors.
The flood risk landscape has dramatically worsened since 2020 with Hurricane Helene headlining 27 disasters in the U.S. in 2024, costing $1 billion or more each.
Research indicates 67% more American homes than previously estimated face high flood risk over the next 30 years due to changing weather patterns.
By 2100, flood exposure could threaten 1.9 billion people globally, with human migration accounting for 77% of the increased risk.
14.6 million properties face substantial flood risk, nearly 70% more than FEMA's classification of 8.7 million high-risk properties, with many property owners unaware.
