Copernicus: 2025 Poised To Be Among The Three Warmest Years On Record

Copernicus reports that 2025 is on course to be among the three warmest years recorded, currently tied with 2023 as the second-hottest behind 2024. November's global average temperature reached 14.02°C, or 1.54°C above pre-industrial levels — surpassing the 1.5°C Paris threshold. Scientists warn the mean for 2023–2025 is likely to exceed 1.5°C for the first time over any three-year period, underscoring urgent need for emissions reduction.

The EU's Copernicus Climate Change Service said on Tuesday that 2025 remains on track to become one of the three warmest years ever recorded.

In its monthly update, Copernicus reports that 2025 is currently tied with 2023 as the second-warmest year on record, trailing only 2024. November was the third-warmest November globally, with a mean temperature of 14.02°C and exceptionally high readings in regions such as the Arctic Ocean.

That month’s temperatures averaged 1.54°C above pre-industrial levels — slightly above the 1.5°C threshold referenced in the Paris Agreement. While researchers do not expect 2025 by itself to remain above that limit for the full year, the mean temperature across 2023–2025 is likely to exceed 1.5°C, which would be the first time any three-year span has done so.

“These milestones are not abstract,” said Samantha Burgess, Copernicus' strategic lead for climate. “They reflect the accelerating pace of climate change and the only way to mitigate future rising temperatures is to rapidly reduce greenhouse gas emissions.”

Regionally, Europe experienced its fifth-warmest November on record, with an average temperature of 5.74°C. Eastern Europe, the Balkans and Turkey saw unusually warm conditions, while Scandinavia and parts of southern Germany were comparatively cool. Only three previous European autumns have matched the warmth of this one.

Experts say these short-term records underline growing climate risks — from Arctic ice loss to heightened extremes of heat and precipitation — and reinforce calls for faster emissions cuts and stronger climate adaptation measures.
