Climate change is a concerning topic, as it is impossible to deny its damaging effects on the planet. Different policy responses have been offered regarding climate change adaptation, and these have brought forward issues related to climate justice. As this topic is still not very well known in Brazil, this paper aims to raise awareness on climate justice concepts and related issues. This is a literature review which analyses climate justice theories and their relation with the concept of climate change adaptation in order to offer a new point-of-view on the topic. This paper has come to the conclusion that the concept of climate change has been created due to the increased importance of climate justice. Its origins lie in climate change activism, which seeks to help the most affected communities. That was when the fight for sharing the burden of climate change emerged, giving rise to the concepts of mitigation and climate adaptation. Thus, the most affected populations should receive assistance in the form of climate change impact adaptation, financed by the countries which are responsible for most greenhouse effect gas emissions, in name of climate justice.

We present a thorough analysis of the scientific production in climate change and adaptation in Brazil. We conducted a bibliometric and bibliographic review to reveal and discuss how climate change research has been carried out. We compared a broader climate change research dataset with a more specific climate adaptation research dataset, to understand the main differences and convergence points, and how science conducted from a mitigation and adaptation perspective demonstrates potential to confront the climate change challenges and drivers in Brazil. Four main clusters of investigation within climate change were detected: (1) impacts on forest and plant development, (2) land use and ecology, (3) adaptation/governance, and (4) climate/atmospheric studies. Only about 5% of the total studies on climate change address adaptation, for which three main clusters of research were identified: (1) adaptation actions and policies; (2) urban environment, vulnerability, and health and (3) food and coastal impacts. Although there are strong research trends in climate change for the Amazon Forest, there was less evidence of studies concerning climate adaptation for this and other Brazilian biomes, smaller cities, rural and traditional communities, and poorer regions. Our results shed a light on the more commonly chosen research topics, their strongest points and potential gaps and trends. This can contribute to the scientific communication and implementation of climate actions in Brazil, and a better understanding of the climate science knowledge from the perspective of a middle-income country.
