United Nations reports greenhouse gas levels reached new record highs in 2025
The United Nations World Meteorological Organisation announced Tuesday that global greenhouse gas concentrations hit unprecedented records in 2025.
Carbon dioxide and methane rise
Concentrations of carbon dioxide reached 426.8 parts per million while methane levels stood at 1,948 parts per billion. Nitrous oxide also climbed to 339.1 parts per billion according to the agency data. These three gases trapped an unprecedented amount of heat within the atmosphere.
Long-term climate impacts expected
The rise in these gases will lock in temperature increases that persist for centuries. Carbon dioxide remains in the air for decades and even centuries after emission. This trend follows eleven consecutive years of being the warmest on record.
Bulletin released before summit
The 22nd annual Greenhouse Gas Bulletin was published ahead of the COP31 climate summit in Antalya. The upcoming event runs from November 9 to 20 in Turkey. Officials warn that burning more fossil fuels continues to drive these concentration levels higher.
