This tendency is also reflected in the composition of the IPCC; where representation from developing countries has improved, much of it is focused on WGII, which publishes regional chapters on impacts and adaptation (83). Science that is conducted in developing countries, which contribute the least to GHG emissions but are the most vulnerable to climate change impacts, often has a different focus than in developed countries, which tend to focus more on large-scale positivist understandings of the physical system and the economics of mitigation (87). Many authors from developing countries who participated in WGIII's AR5 did so through coauthorship relationships and “institutional pathways” that are based in the developed world (88). This might be responsible for the “strong harmonization of views [in AR5 WGIII], compared with the diversity one finds across the social sciences of climate change more broadly” (88, p. 98). The forgoing considerations give rise to the question, how should the IPCC engage with the realities of unequal global development and the vast differences between rich and poor nations.
