Climate Change Knowledge on Wikipedia: A Cross-Language Comparative Analysis

A comparative assessment was conducted focusing on article quality, citation indices, article popularity trends over a defined period, and author engagement across various climate-related topics and Wikipedia language editions. To identify the most frequently cited climate change articles, over 1 billion wikilinks between articles extracted from Wikimedia dumps were analyzed. The initial findings reveal significant variations in the availability and depth of climate change information, reflecting disparities in knowledge dissemination, editorial engagement, and public interest among diverse linguistic communities of Wikipedia. The study was presented at Wikimania 2025: https://wikimania.wikimedia.org/wiki/2025:Wikimania
