Carbon Brief publishes separate rankings based on its Project Cosmos database, which it describes as the largest known dataset for climate-change research citation analysis. The outlet presents (1) a list of the most highly cited “institutions” involved in climate research, (2) a list of the most highly cited climate scientists, and (3) a list of the most highly cited climate publications. The rankings are derived from citation data contained in Cosmos, and are used by Carbon Brief to identify leading entities across different categories of climate scholarship. In each case, the focus is on citation prominence within the database, which Carbon Brief frames as a way to highlight influential contributors, organizations, and papers in the field. The posts link each ranking to the corresponding Cosmos category—institutions, researchers, and publications—offering readers a comparative view of which parts of the climate research community attract the most citations. The outlets do not describe the rankings as measuring impact beyond citations, but rather as an analysis of highly cited records in the Cosmos database.
