2025 is the third-warmest year on record

The year 2025 was the third-warmest year on record, with the global temperature being 1.47 degrees Celsius higher than the pre-industrial level.

This is just a bit cooler than 2023 and 2024, which were the hottest years ever recorded.

The average temperature over the past three years was 1.51 degrees Celsius, which is higher than the 1.5-degree limit set by the 2015 Paris Agreement.

The main reason for this warming is the increase in greenhouse gases, but other factors like reduced CO2 absorption by natural sinks, less cooling from aerosols, and high ocean temperatures also played a role.

Additionally, the El Niño and La Niña weather patterns contributed to the warming.

The ocean has absorbed most of the extra heat, causing sea surface temperatures to rise as well.
