US Edition2025 was the world's third-warmest year on record, EU scientists say
The 2023-25 period is the first to exceed 1.5°C above pre-industrial levels, with record polar warmth, extreme weather, and wildfire emissions reported by Copernicus.
- Last year, the Copernicus Climate Change Service and the European Centre for Medium-Range Weather Forecasts reported 2025 was the planet's third-warmest year, with an average temperature of 14.97 degrees Celsius.
- Scientists say the spike was driven by greenhouse gases from fossil fuels and weakened natural carbon sinks, while high sea-surface temperatures linked to El Nino and aerosol changes amplified warming.
- Copernicus data show sea ice at both poles hit record lows, the Antarctic had its warmest annual temperature, and Berkeley Earth calculated 770 million people faced record heat, including 450 million in China.
- Scientists caution the economic and health costs will grow as rising global temperatures intensify extreme weather, causing billions in damage despite the $120 billion adaptation pledge at last year's United Nations climate summit for vulnerable nations.
- Scientists predict 2026 may match 2025's heat, with Copernicus finding 2023-25 exceeded 1.5C, and Laurence Rouil said `The atmosphere is sending us a message, and we must listen`.

The year 2025 was the third warmest year on record, according to researchers from the EU's Copernicus climate change monitoring program and the American non-profit research organization Berkeley Earth.
Global Warming Surge: 2025 Among the Hottest Years | Science-Environment
In 2025, average global temperatures remained significantly high, marking it among the planet's three warmest years on record. The persistent warming trend confirmed concerns over exceeding the 1.5 degrees Celsius threshold, which is critical in determining severe climate impacts. Extreme weather events continue to intensify as a result.
The Earth recorded its third warmest year on record in 2025. This continues a period of unprecedented heat, and experts do not expect any changes this year, according to researchers from the EU's climate monitoring program Copernicus and the California-based nonprofit research organization Berkeley Earth.
