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, according to new data from the European Copernicus climate service and the Met Office.
However, the last three years have been the warmest ever recorded, bringing the planet closer to breaching international climate targets. Even with the La Niña effect, 2025 was significantly warmer than temperatures observed a decade ago, primarily due to ongoing carbon emissions from human activities.
Scientists express concerns that without a significant reduction in emissions, further temperature records and extreme weather events are inevitable. 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, remarked Dr. Samantha Burgess, the deputy director of Copernicus.
The global average temperature in 2025 was more than 1.4C above pre-industrial levels, indicating a troubling trajectory as humanity continues to emit greenhouse gases at unsustainable rates.
Last year was marked not only by elevated temperatures but also by extreme weather events, such as the destructive California wildfires in January and Hurricane Melissa in October, both linked to the effects of climate change. The persistent warmth observed into 2025 suggests that the planet is already vulnerable to significant warming even in less favorable climate conditions.
The implications of climate change are pronounced, with many regions experiencing unprecedented heatwaves and storms, raising alarms about the future. Experts advocate for urgent interventions to cut emissions and develop resilience strategies to adapt to the changing global landscape.
