The Core Finding: A Six-Decade Heat Deficit
The WMO's 2025 State of Climate Report introduces the concept of Earth's energy imbalance — a heat surplus built over 60 years that will continue to warm the planet even if emissions stopped today.
Key Numbers from the Report
CO2 is 50% above pre-industrial levels — its highest in 2 million years. The last decade was the hottest on record. Global emissions hit a new peak in 2025 even as renewables overtook coal in electricity generation.
Ocean Heat: The Long Memory of Climate Change
Oceans absorb most of the Earth's heat surplus. Warmer seas intensify tropical storms and melt ice, reducing Earth's ability to reflect solar radiation — creating a self-reinforcing feedback loop.
Melting Ice and the Albedo Effect
As ice melts, dark ocean water replaces reflective ice surfaces. This lowers Earth's albedo — the fraction of sunlight reflected back to space — and accelerates the energy imbalance the report warns about.
What This Means for Policy
Mitigation and adaptation must run in parallel. Emissions cuts prevent future warming; adaptation spending addresses warming that is already locked in. Both require stable, long-term policy frameworks insulated from short-term politics.
India's Specific Exposure
India Meteorological Department data shows rising sea surface temperatures in the Bay of Bengal and Arabian Sea, affecting monsoon variability and cyclone intensity — direct consequences of the ocean heat accumulation the WMO report describes.
