Greenhouse Gas Levels Hit New Record Highs in 2025
The UN weather agency said rising emissions are locking in longer-term warming as carbon dioxide, methane and nitrous oxide all reached new highs.
- The United Nations announced Tuesday that concentrations of carbon dioxide, methane, and nitrous oxide reached unprecedented record highs in 2025, locking in climate impacts that will persist for centuries.
- Compared to pre-industrial levels, the three main greenhouse gases reached 153%, 267%, and 126% respectively, while CO2 accounts for about 66% of the warming effect and methane contributes about 16%.
- The World Meteorological Organization's 22nd annual Greenhouse Gas Bulletin, released ahead of the COP31 UN climate summit in Antalya, Turkey, warns that sulfur hexafluoride has been rising steadily over the past three decades.
- WMO deputy secretary-general Ko Barrett said, "Greenhouse gases are trapping an unprecedented amount of heat in the atmosphere, providing energy for more extreme weather and associated risks," noting the past 11 years have been the warmest on record.
- Driven by fossil fuel burning and a powerful El Niño, concentrations will likely increase by 2.8 ppm in 2026, WMO senior scientific officer Oksana Tarasova warned.
