Feng et al. use a Bayesian inverse method to interpret global-scale atmospheric CO2 data from the NASA Orbiting Carbon Observatory. They find that the global annual mean atmospheric CO2 growth rate in 2023 was one of the highest since records began in 1958. Their analysis suggest that ongoing environmental degradation of the Amazon is now playing a substantial role in increasing the global atmospheric CO2 growth rate. This findings emphasize how important continues measurements and regularly reporting of regional CO2 fluxes are to better understand changes in the CO2 cycle and be able deliver frequent actionable information for policy makers.
