Executive Summary
Record global heat in 2025 is driving higher cooling demand, stressing power systems, and pushing extreme heat exposure toward midcentury doubling
- 2025 ranked among the hottest years on record, with the past three years averaging above 1.5 C for the first time
- Copernicus said current emissions put the world on track to exceed the Paris 1.5 C limit permanently by the end of the decade
- Heat waves, drought and wildfires are straining electricity generation, transmission and fuel supply chains
- The World Meteorological Organization said climate extremes are reshaping global power demand and energy system risk
- Oxford researchers projected 3.79 billion people could face extreme heat by 2050 under 2 C warming
- The study found cooling demand rises sharply in tropical and equatorial regions while colder countries also face more hot days
- Open climate datasets and monitoring are being used to guide adaptation planning and building-sector resilience
Quick Facts
- What: Record heat is raising cooling demand and grid risk
- Where: Globally with major impacts in tropical and polar regions
- Why: Rising greenhouse gases and warming are intensifying extremes
- Who: Climate agencies researchers and energy system planners
- When: In 2025 with risks growing toward 2050
