Rising temperatures across several parts of the world are creating fresh challenges for critical infrastructure, including AI data centres. As countries such as India and several parts of Europe experience intense heatwaves with temperatures crossing 40°C, technology companies are being forced to rethink how they keep their data centres running efficiently.
Data centres, which power cloud computing, artificial intelligence and online services, already generate massive amounts of heat because they house thousands of high-performance servers. During extreme weather, cooling systems have to work much harder to maintain safe operating temperatures, leading to higher electricity consumption and increased operational costs. If cooling systems fail, servers can overheat, potentially causing service disruptions and equipment damage.
According to a study by First Street, nearly 79% of the world’s data centre capacity is exposed to significant climate-related risks, including extreme heat, floods, wildfires and other natural hazards. Such events can interrupt operations, disrupt online services and result in costly repairs and maintenance.
At the same time, the global data centre industry continues to expand rapidly. Around 64% of new data centre capacity is now being developed outside traditional data centre hubs as companies look for locations with better infrastructure and lower climate risks. Countries such as Brazil are emerging as major destinations for new data centre investments.
To cope with rising temperatures, technology companies are redesigning cooling systems and adopting more efficient thermal management solutions. However, cooling already accounts for nearly 40% of a data centre’s electricity consumption under normal conditions. During heatwaves, energy demand rises even further, increasing the risk of power shortages and blackouts.
To minimise climate-related disruptions, companies are carefully selecting locations that are less vulnerable to extreme weather, building backup infrastructure to improve reliability and deploying real-time monitoring systems that continuously track temperatures, power usage and equipment performance.
As AI adoption accelerates worldwide, ensuring that data centres remain resilient against climate change is becoming a critical priority for the technology industry.
