A bibliographic review on anthropogenic climate change and drought

Abstract

The Nanjing University of Information Science and Technology reviewed 7561 publications, identifying 1271 relevant works published between 2014 and 2022 based on data from the Web of Science database. The PRISMA 2020 technique, with appropriate inclusion and exclusion criteria to minimize errors, revealed significant annual increases in publishing volume during this period. The United States and China ranked first and second in terms of publication volume and citations, while the Peoples of China and the United States ranked first in terms of publication quality. Inequalities in network density and linkages were found, with the Chinese Academy of Sciences receiving the most citations and degrees. The document co-citation analysis network was developed to increase understanding of the frequency and amplitude of bursts of different publications in distinct clusters. Seneviratne SI in Cluster 1, (2014) had the most citations (18) and the highest strength (4.81). CiteSpace’s analytical technology identifies high-frequency keywords, explores co-occurrence patterns, and highlights emerging concepts, shedding light on cutting-edge research dynamics and the impact of new ideas from policies or public events. In this review, bursts of new concepts highlight rapid growth in the field. Seneviratne SI (2014) and Seager R with Zhang Q (2015) were top contributors in citations and references. Notably, knowledge gaps exist in anthropogenic climate dynamics, environmental factors, drought risk mitigation, and attribution. Future scholars should focus on these and comparable issues, while Chinese and American authors should prioritize article quality above publication numbers.
