Summary
Oceans hit record temperatures for a third consecutive year in 2025, while the Greenland Ice Sheet lost about 129 gigatons of ice, according to the State of the Climate report released Monday.
The report ties the worsening extremes to continued fossil-fuel burning, which pushed greenhouse gases to record highs and drove more dangerous heat, flooding, drought and wildfire conditions.
Marine heatwaves covered 87% of the oceans last year, cloudiness fell to the second-lowest level since 1980, and some northern forests and tundra emitted more carbon dioxide than they absorbed.
Europe’s average temperature has risen about 3.6 degrees Fahrenheit since the 1960s, with extreme highs up as much as 18 degrees, while this summer’s drought and wildfires there have already caused more than $3 billion in damage.
The findings add pressure on governments after last year’s International Court of Justice opinion said countries could face liability for cross-border climate harm they knowingly cause or fail to prevent.
