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. |

The Paris Agreement sets the target to limit increases in mean global temperature to well below 2¡ãC, preferably to 1.5¡ãC, compared with preindustrial levels. Carbon neutrality is the preferred route to reach this target.1 This requires primarily a reduction of CO2 emissions to the atmosphere but also an increase of carbon sinks or negative emissions (absorption of atmospheric CO2). The ocean is the largest active carbon pool on Earth, acting as the key regulator to global climate change, and thus has great potential for carbon negative emission.
