The World Meteorological Organization confirmed last year's Earth energy imbalance reached unprecedented levels, marking a critical escalation in climate change impacts. Satellite and ground monitoring revealed the planet absorbed significantly more solar radiation than it emitted, with oceans acting as the primary heat sink, storing approximately 91 per cent of the excess energy. This imbalance, more than doubling since 2000, underscores the accelerating pace of global warming. Ocean heat in 2025 set a new observational record, surpassing 2024's high, indicating heat is penetrating deeper layers. 11 zettajoules of heat were added annually since 2005, equivalent to 18 times humanity's total yearly energy consumption, with the 2025 surge alone roughly 39 times that figure.

This stored heat, likely locked in for centuries, poses long-term risks to marine ecosystems and global weather patterns. While the WMO noted stable funding despite initial concerns, the report emphasizes the urgent need for climate action to mitigate escalating economic costs across sectors like insurance, agriculture, and infrastructure. The findings signal a profound shift in the planetary energy budget with far-reaching implications for global markets and business resilience.
