| On the cover: The rising in the popularity of big data, artificial intelligence, and simulation technologies has opened up new opportunities for the development of our society. The close integration of real and artificial societies has become a trend, bringing in novel concepts such as parallel society and metaverse. The artificial society system describes, predicts, and guides the real society system, in a closed-loop, iterative, and spiral-rising way, forming a new mode of social operation driven by Data-AI-Simulation techniques. In the future, with the further development of interdisciplinary cooperation and the continuous advancement of technologies, living in metaverse is within reach. |

Records of methane emissions and mitigation solutions
During the past decades, public attention regarding global warming has mainly focused on CO2 reduction; however, CH4, another important greenhouse gas, has a global warming potential that is 84 times higher than that of CO2 on 20-year basis. The annual atmospheric amount of CH4 in 2020 reached its highest level since systematic monitoring began in 1983 (Figure 1A). To date, despite Covid-19 shutdowns, methane has contributed approximately 30% to global warming. Recently, a series of timely appeals, such as "The Global Methane Pledge" signed at the United Nations Climate Change Conference (COP26) and the ¡°Global Methane Assessment¡± from the United Nations Environment Program, have called on global methane reduction and mitigation.
