Global greenhouse gas levels hit new heights in 2025: report
Global atmospheric concentrations of heat-trapping greenhouse gases reached unprecedented highs in 2025, according to a report released by the World Meteorological Organization (WMO), driven by continued fossil fuel combustion and industrial activity. Carbon dioxide (CO₂) levels in the atmosphere hit a record high of 426.8 parts per million (ppm) — meaning there are now 1.5 times as much CO₂ in…
In 2025, the World Meteorological Organization (WMO) reported that global atmospheric concentrations of heat-trapping greenhouse gases reached record-breaking levels, according to a recent report. The primary culprit was carbon dioxide (CO₂), which surged to an astonishing 426.8 parts per million (ppm), marking a 50% increase since the Industrial Revolution of 1750.
Methane and nitrous oxide, two other potent greenhouse gases, also hit new highs. However, there was a minor glimmer of hope regarding CO₂ levels. The annual increase in CO₂ slowed to 2.8 parts per million in 2025, a significant drop from 3.5 parts per million in the previous year. This slowdown was attributed to the revival of land-based carbon sinks and a decline in wildfire activity following the strong El Niño events of 2023 and 2024. The Korea Meteorological Administration's data further revealed a more severe trend.
