The Intergovernmental Panel on Climate Change (IPCC) periodically reviews the current state of scientific knowledge on climate change. Some analysts have argued that although it has become more inclusive over time, the IPCC is still not inclusive enough. In particular, they accuse the IPCC of neglecting expertise from developing countries.

This map shows that most authors and contributors to the sixth IPCC report are coming from high-income countries in North America and Europe, and some middle-income countries like China, India and Brazil. Few researchers from Africa, South-East Asia, Central America and the Middle East are contributing to the IPCC, although climate change severely affects these regions.
