Global temperatures in 2025 did not quite reach the heights of 2024, thanks to the cooling influence of the natural La Niña weather pattern in the Pacific, new data from the European Copernicus climate service and the Met Office shows.

But the last three years were the world's warmest ever recorded, bringing the planet closer to breaching international climate targets.

Despite natural cooling from La Niña, 2025 was still much warmer than temperatures even a decade ago, as humanity's carbon emissions continue to heat the planet.

That will inevitably lead to further temperature records – and worsening weather extremes – unless emissions are sharply reduced, scientists warn.

"If we go twenty years into the future and we look back at this period of the mid-2020s, we will see these years as relatively cool," said Dr Samantha Burgess, deputy director of Copernicus.
