Global average CO2 concentrations jumped by a record 3.5 parts per million in 2024, reaching 423.9 ppm, according to the World Meteorological Organization. This marks the largest annual increase since measurements began in 1957. The surge is attributed to fossil fuel emissions, wildfires, and reduced carbon uptake by lands and oceans.
