An analysis of 97 global markets found that chronic stress from heat and drought threatens more than half of all data centers worldwide

Flooding, extreme winds, wildfires, and other hazards threaten 79% of global data center capacity, exposing operators to service disruptions, higher downtime, and elevated insurance and repair expenses, according to a new report by First Street, a climate risk analytics firm.
The study, reported by CNBC, examined 97 global data center markets. Chronic climate pressures — including extreme heat and drought — affect more than half of data center markets globally, undermining energy efficiency and pushing up operating costs. Reporting from E&E News pegged that share at 54%, and the First Street report drew a pointed conclusion: "scale is being built where operating conditions are hardest, not where they're easiest."
Geographically, Asia-Pacific bears the heaviest burden, with acute risk touching 89% of its data center capacity — well above the 50% figure for the Americas and 46% for Europe, the Middle East, and Africa. The study identified Northern Virginia, Johor in Malaysia, and Marseille, France as standout examples of high-exposure markets, while Nordic countries ranked at the opposite end of the risk spectrum.
First Street CEO Matthew Eby argued that conventional risk assessment tools have not kept pace with a changing climate. "Most underwriting for real assets still uses historical data, but the climate is no longer behaving the way the historical record would predict," he said in a statement. "As heat, drought, and water stress increase, outdated models simply don't offer a complete view of risk anymore."
Jeremy Porter, First Street's chief economist, singled out government flood modeling as a particular vulnerability, arguing those tools are anchored to past precipitation data that ignores how a warmer atmosphere retains more moisture and generates more intense rainfall events. Porter cautioned that hardening a structure against extreme weather addresses only part of the problem; the grid connections, access roads, and surrounding community infrastructure feeding into a facility can become failure points that render even a well-fortified data center inoperable.
The findings arrive as data centers are drawing growing scrutiny from state legislators over their electricity and water consumption. XDI, a separate climate risk research firm, reviewed plans for around 2,600 data centers under development globally and determined that over 150 are slated for high-risk sites — with North America accounting for more than 70 of them, Bloomberg reported. Because a data center's operational lifespan commonly stretches two to three decades, the locations chosen today will shape financial exposure well into mid-century.
