Powerful critiques of the epistemic community framework have emerged from the field of science and technology studies. These analyses note that support for a shared perception of environmental problems may be the result of diverse social and political influences, for example, shared disciplinary orientations, economic interests, political ideologies or discursive framings. This chapter builds on and extends these observations through an ethnographic study of Brazilian scientists and policy makers engaged with international climate science and politics. Brazilian climate‐related affairs have been directed by a few key persons affiliated with the Brazilian Ministry of Science and Technology and the Brazilian Ministry of External Relations. Brazilian climate scientists and policy makers may be united in their tendency to bring an interpretive framework shaped by experiences of bias and shared memories of colonialism to bear on climate science and politics.
