Greenhouse gas levels reached new record high in 2025

Carbon dioxide concentrations in the atmosphere reached a record high in 2025, according to reports by UPI, The Times of India, and other outlets citing the World Meteorological Organization. UPI reported that global carbon dioxide levels reached 153 per cent of pre-industrialization levels, reaching an average global concentration of 426.8 parts per million. [1][2][3][4][5][6]

The United Nations climate agency revealed the figures in its annual Greenhouse Gas Bulletin. UPI reported that the 2025 concentration represents a 0.68 per cent increase from 423.9 parts per million in 2024. The Geneva-based World Meteorological Organization has monitored carbon dioxide levels since 2004, when the concentration measured 377.5 parts per million, marking a 13.06 per cent rise over that period.

As FTMQ News reported earlier, major emitters continue to struggle with climate action despite global commitments. Analysis published earlier in October showed that international efforts are falling short of targets set under the 2016 Paris Agreement. [9]

The long lifetime of carbon dioxide in the atmosphere commits the planet to continued warming, according to reports by The Times of India and NewsCord. NewsCord added that the World Meteorological Organization warned climate impacts will persist for centuries. [2][6]
