CO2 Is The Number to Watch When the trend for atmospheric CO2 trend begins to falter and fall, we can expect global average temperature to follow. Average carbon dioxide (CO₂) levels in the atmosphere worldwide from 1959 to 2024 (in parts per million) [Graph], National Oceanic and Atmospheric Administration, & ESRL, January 5, 2025

Figure 5.The central estimate of the forecast annual CO 2 increment for 2024-2025 in the context of the frequency distribution of the observed annual increment for each year in the Mauna Loa record The last four complete years plus the current year are shown on the first graph. The Global Monitoring Laboratory has measured carbon dioxide and other greenhouse gases for several decades at a globally distributed network of air sampling sites [Conway, 1994]
NASA SVS Concentration Increase of Atmospheric Carbon Dioxide (CO₂). Monthly mean atmospheric carbon dioxide (CO₂) concentrations reached a record high of 426.91 parts per million (ppm) in June 2024. The graphs show monthly mean carbon dioxide globally averaged over marine surface sites
Atmospheric CO2 levels accelerate upwards, smashing records National Observer. Monthly comparison of CO2 levels measured by NOAA & Scripps at Mauna Loa. Long-term trends in CO₂ concentrations can be measured at high-resolution using preserved air samples from ice cores.
