Shi Yusheng’s research team of the CAS Aerospace Information Innovation Institute has quantified the impact of global fire carbon emissions on atmospheric carbon dioxide concentration. The research results show that the annual average impact of global fire carbon emissions on atmospheric carbon dioxide concentration can reach 2.4 ppm, indicating that fire is one of the key factors in the increase in the concentration of carbon dioxide in the global atmosphere has a significant impact on global warming and climate change.

Africa is the region with the highest biomass burning emissions in the world, resulting in the highest carbon dioxide concentration in summer, an increase of 7.9 to 13.0 parts per million. The study provides a new approach and method for quantifying the impact of fire carbon emissions on changes in atmospheric carbon dioxide concentration, and provides a scientific basis for the control of biomass combustion.
