The World Meteorological Organization (WMO) has revealed that atmospheric carbon dioxide (CO2) levels surged by a record-breaking amount in 2024, reaching an alarming global average of 423.9 parts per million (ppm). This marks the highest level since systematic observations began in 1957, underscoring the world’s accelerating march toward dangerous climate thresholds. The WMO’s latest Greenhouse Gas Bulletin attributes this unprecedented rise to continued human-induced emissions, intensified wildfires, and a troubling decline in the efficiency of natural carbon sinks such as forests and oceans.
According to the report, CO2 concentrations grew by 3.5 ppm from 2023 to 2024—three times faster than the average annual growth rate seen in the 1960s. “The heat trapped by CO2 and other greenhou
