Fake controversies have influenced policy making on health and environmental issues for decades, resulting in major implementation setbacks worldwide. As a case study, in this paper we examine fake controversies produced by a small group of active Brazilian researchers that have seriously impacted environmental conservation, particularly in issues related to deforestation and climate change. Based on the literature, we develop a typology of strategies deployed in fake controversies, which include manufacturing uncertainty, misusing scientific credentials, and disregarding scientific literature. Afterwards, we examine the influence of this group of contrarians at the National Congress. We then analyze the fake controversies promoted by these contrarians and argue that, to properly understand them, we need to consider a strategy so far overlooked in the literature: the manufacture of "pseudo-facts", namely, affirmations at odds with the established literature but that strives to appear as scientific facts. Unlike other contexts, in which contrarians have mainly sought to cast doubt on consensual issues by arguing that there are still considerable uncertainties surrounding them, in Brazil pseudo-facts on deforestation have been produced and published outside the peer-reviewed literature. We conclude the study with recommendations on how to oppose fake scientific controversies that threaten environmental conservation in general. [ABSTRACT FROM AUTHOR]

This article is an enquiry into Brazil's evolving responses to global climate change norms. Following an overview of the evolution of international normative frameworks of climate change governance, I examine the relationship between some of these international norms and domestic environmental politics in Brazil. Internationally, the analysis focuses on the North/South political debate about climate change and its role in shaping understandings about the impact and responses to global warming. Domestically, I explore the evolving relationship between state and private actors in the decision-making process. I argue that Brazil's official position on climate change negotiations is currently influenced by a nationalist/developmental approach based on the particular worldview of the dominant faction within the foreign ministry and backed up by private groups, powerful sectors in the military establishment, key ministries, and the presidency. Yet, this worldview has been increasingly undermined/permeated by other state and nonstate actors, who are more closely aligned with the environmental concerns of international stakeholders. The ensuing domestic conflict has important implications for the legitimacy and coherence of the Brazilian position in international climate change negotiations. [ABSTRACT FROM AUTHOR]
