The World’s Most Influential Climate Scientists Revealed

AI Insight

Carbon Brief has created a ranking called the Cosmos 500 that identifies the most highly cited climate scientists based on their database of over 1.8 million climate change publications. The citation score is calculated by counting how many times each author's publications are referenced by other works within the Cosmos database. This ranking provides a measure of which researchers have had the greatest influence on climate change literature within this specific collection.


This ranking helps identify the most influential voices in climate science and can guide policymakers, journalists, and the public toward authoritative sources of climate information. It provides a data-driven approach to understanding which researchers have shaped the direction of climate change research.

Carbon Brief’s Project Cosmos is the largest known database of climate change research, featuring more than 1.8m individual publications.

Every publication has a list of authors – the experts who carried out fieldwork, analysed data and drafted the document itself.

Hundreds of thousands of experts are listed as authors in these studies, books and reports.

Each publication also has a list of references – the other academic works on which the authors drew to develop their research.

Carbon Brief has calculated a citation score for each expert, by counting how many times their publications are referenced by others within the Cosmos database.

The Cosmos 500 ranking shows the most highly cited academics in Carbon Brief’s database, based on their citation score.

(This ranking only counts references from within Carbon Brief’s Cosmos database. This is distinct from the citation count given by, for example, Google Scholar, which counts all references the publication has ever received.)
