State of the Global Climate 2025
- WMO State of Climate report confirms 2015-2025 hottest 11 years on record
- Earth’s energy imbalance is highest in sixty five-year record
- The ocean has been absorbing about eighteen times the annual human energy use each year for the past two decades
- Extreme weather impacts millions and costs billions
- World Meteorological Day: observing today to protect tomorrow
WMO’s State of the Global Climate report 2025 confirms that 2015-2025 are the hottest 11-years on record, and that 2025 was the second or third hottest year on record, at about 1.43 °C above the 1850-1900 average. Extreme events around the world, including intense heat, heavy rainfall and tropical cyclones, caused disruption and devastation and highlighted the vulnerability of our inter-connected economies and societies.
The ocean continues to warm and absorb carbon dioxide. It has been absorbing the equivalent of about eighteen times the annual human energy use each year for the past two decades. Annual sea ice extent in the Arctic was at or near a record low, Antarctic sea ice extent was the third lowest on record, and glacier melt continued unabated, according to the report.
For the first time, the report includes the Earth’s energy imbalance as one of the key climate indicators.
