Global temperatures reached unprecedented highs in 2025, marking the third-hottest year on record, as climate experts warn that 2026 could continue the alarming trend of accelerating global warming.
Data from the EU Copernicus Climate Change Service and Berkeley Earth show that the past 11 years have been the warmest ever recorded, with 2024 and 2023 taking the first and second spots, respectively.
Global Temperatures Exceed 1.5°C Threshold
For the first time, average global temperatures have exceeded 1.5°C above pre-industrial levels for three consecutive years, raising concerns about the world’s ability to meet Paris Agreement climate targets. Copernicus officials noted that this milestone reflects the urgent need for accelerated greenhouse gas emissions reductions.
Berkeley Earth highlighted that the 2023–2025 warming spike was unusually extreme, indicating a potential acceleration of global climate change. In 2025, global temperatures averaged 1.47°C above pre-industrial levels, compared to 1.6°C in 2024.
Record Heat Affects Millions Globally
Around 770 million people experienced record-high annual temperatures in 2025. No region recorded a record-cold year. The Antarctic experienced its warmest year on record, while the Arctic recorded its second-hottest year, Copernicus data shows.
Scientists warn that these extreme temperatures not only threaten ecosystems but also exacerbate climate-related disasters such as wildfires, heatwaves, droughts, and glacial melting.
2026 Likely to Set New Climate Records
Looking ahead, climate experts caution that 2026 could become another record-breaking year, particularly if an El Niño event develops. Berkeley Earth predicts that 2026 is most likely to rank as the fourth warmest year since 1850.
Global Emissions Remain a Concern
Despite international climate agreements, global efforts to curb carbon emissions remain inconsistent. Emissions in the United States increased in 2025, while Europe’s pace of reductions slowed, adding further pressure on achieving global climate targets.
Experts say that the continued rise in global temperatures highlights the critical importance of renewable energy adoption, climate policy enforcement, and sustainable development worldwide.
