UN Reports Record High Greenhouse Gas Levels in 2025 Ahead of COP31 Summit
Greenhouse gas concentrations reached record highs in 2025, with carbon dioxide at 426.8 ppm, methane and nitrous oxide also hitting unprecedented levels, according to the UN's World Meteorological Organization. These increases contribute to long-term climate warming and more extreme weather events. The report highlights that the rise reflects accumulated atmospheric gases rather than annual emissions. The WMO warned that the upcoming El Niño could further elevate greenhouse gas levels, intensifying climate impacts ahead of the COP31 summit in Turkey.
