Information integrity on extreme weather events
In September 2025, UNESCO, the UN Secretariat, and the Government of Brazil announced the first group of proposals selected under the Global Fund for Information Integrity on Climate Change, after receiving 447 proposals from nearly 100 countries.
Among the selected projects was Advancing Information Integrity on Extreme Weather and Climate-related events in Wikipedia and Wikidata, which became part of the Global Initiative for Information Integrity on Climate Change.
This initiative was a regional collaboration in South America between Wikimedia Brasil and the Working Group on Climate Justice and Wikimedia Projects composed by Wikimedia affiliate organizations from Argentina, Bolivia, Chile, Colombia, Peru and Uruguay. While regionally rooted, the project had global impact and design, leveraging Wikipedia's worldwide reach.
This selection marked a key milestone in the global fight against climate disinformation, identified as one of the main barriers to science-based climate action, ahead of COP30, which was held in Brazil in November 2025.
Objectives
[edit]The project aimed to strengthen information integrity on climate change across Wikimedia platforms by:
- Developing a multilingual Wikidata model of extreme weather and climate-related events.
- Analyzing disinformation patterns in Wikipedia articles across English, Spanish, and Portuguese to identify common tactics and vulnerabilities in climate-related content.
- Ensuring information interoperability through technical and legal standards (linked open data, open licenses) to enable research sharing and global learning processes that adapt to evolving disinformation tactics.
