WHAT THE EVIDENCE SAYS
A bibliometric review of the literature cited across IPCC working groups found increasing representation of countries, institutions and journals between assessment cycles, alongside persistent dominance by developed-country research.
WHY IT MATTERS / OUR READ
Evidence systems have their own geographic filters; whose studies enter syntheses is worth watching alongside the conclusions themselves.
CAVEATS / UNCERTAINTY
Bibliometrics alone cannot demonstrate that particular findings or policy recommendations were biased.
