Decadal variability in δ18O over the East Asian monsoon region response to solar activity over the last millennium

Science China Press
Peer-Reviewed Publication

Precipitation δ¹⁸O provides important insights into the decadal variability of the East Asian monsoon. Using both isotope-enabled climate simulations and reconstructions, this study found a quasi-11-year cycle in precipitation δ¹⁸O (δ¹⁸O_p) across the monsoon region. The cycle was driven by enhanced solar activity, which strengthens the Walker circulation and increases moisture transport from the equatorial Pacific. The results have suggested that the quasi-11-year δ18O_p cycle primarily reflects shifts in moisture sources driven by solar activity. The findings were recently published in SCIENCE CHINA Earth Sciences.

Well-publicized polar geoengineering ideas will not help and could harm, warn experts

Frontiers
Peer-Reviewed Publication

Five well-publicized polar geoengineering ideas are highly unlikely to help the polar regions and could harm ecosystems, communities, international relations, and our chances of reaching net zero by 2050.

Taiwan study analyzes attributes of resilience after major earthquakes

Seismological Society of America
Peer-Reviewed Publication

Resilience is a term often discussed in the face of a natural disaster such as a major earthquake, but the attributes of resilience and how they interact are rarely analyzed, researchers say in a new study published in the Bulletin of the Seismological Society of America.

Researchers discover massive geo-hydrogen source to the west of the Mussau Trench

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Researchers from the Institute of Oceanology of the Chinese Academy of Sciences and their collaborators discovered and analyzed a large pipe swarm—a cluster of cylindrical geological structures—with remnants of hydrogen hydrothermal activity on the east Caroline Plate, west of the Mussau Trench.
