Indian authorities have issued an urgent warning as a severe heatwave grips the capital, Delhi, with temperatures expected to exceed 45 degrees Celsius. This meteorological event is not merely a climate anomaly; it represents a strategic vulnerability in India's critical infrastructure and military readiness. Concurrently, the United Kingdom is set to conduct an emergency review of its heat resilience framework, a move that underscores the growing recognition of extreme weather as a threat vector.
For too long, Western defence establishments have focused on conventional state actors, neglecting the asymmetric power of climate-driven disruption. The India Meteorological Department's advisory, coupled with the UK's defensive pivot, signals a new axis of vulnerability. Hostile state actors could exploit such environmental stressors to strain national grid capacities, degrade logistical supply chains, and create windows of opportunity for cyber or kinetic operations.
India's ability to maintain operational tempo during heatwaves is a critical metric of its strategic pivot towards resilience. The UK review, meanwhile, must extend beyond civilian comfort to military installations and NATO readiness. As I have repeatedly cautioned in closed briefings, thermobaric threats are not limited to munitions; they manifest in degraded human performance, data centre failures, and contested air superiority due to reduced lift capacity.
This is not a drill. The chessboard is heating up, and the next move may not come from a rival capital but from the sky itself.
