After the warmest year ever recorded, global carbon dioxide (CO₂) concentrations in 2024 reached their highest level in history, the World Meteorological Organization (WMO) said Wednesday.

According to the WMO’s annual Greenhouse Gas Bulletin, CO₂ levels saw their steepest-ever increase, rising by about 3.5 parts per million (ppm) between 2023 and 2024. It marks the sharpest jump since 1957, when modern CO₂ measurements began.

The report noted that the growth rate of CO₂ has tripled since the 1960s, accelerating from an average annual increase of 0.8 ppm to 2.4 ppm during 2011–2020. For comparison, WMO’s Global Atmosphere Watch stations recorded an average CO₂ concentration of 377.1 ppm in 2004 and 423.9 ppm in 2024, showing the rapid accumulation over two decades.
