Many scientists have described the anthropogenic climate changes as one of the most pervasive threat of our time that will form this and future generations. Despite that is the climate change is still controversial and missing from the American security agenda. The purpose of this study is to empirically analyse the American environmental discourse under the administration of Donald Trump and the omission of climate changes in the security agenda. To be able to explain the absence of the climate changes in the American security agenda, the environmental discourse will be analysed and the theoretical framework of Copenhagen’s school of securitization will be used to define the current description of the environment, the climate threats, and the global warming. By using a qualitative text analysis, consisting of a discourse analysis, lectures, debates, and documents from the Trump administration are examined, to be able to understand how the discourse is constructed and thus how the omission of the climate changes from the security agenda can be understood by using the securitization theory. The study indicates that the approach taken by the Trump administration on the American environmental discourse is produced can prevent the climate changes, the global warming, and the environment to be securitized, which in its turn can contribute to understanding of why it has not been brought up in the American security agenda. In the analysis it can be concluded that the Trump administration have moved towards a morepoliticized discourse, but also towards a depoliticized discourse.

Master's Thesis Kristýna Čermáková Abstract This master's thesis explores the topic of the securitization of migration in the Czech Republic and the gender dimension of the discourse on migration. After a theoretical exploration of the migratory process and the specificities of its female face, a discourse analysis of the Czech media will present the main epistemological core of the work. The primary research question attempts to identify the ways in which the Czech media contributes to the shifting perception of migration as belonging to the sphere of politics, even presenting migration as a threat to security. The thesis is divided into four chapters. The first chapter provides a theoretical insight into migration studies, the motives to migrate and the phenomenon of forced migration. Despite the general assumption of mainstream academics that migrants are mainly men, the second chapter shows that women's experiences with migration differ greatly from those of men. Based on the Copenhagen stream of thought, the discourse analysis of the Czech media carried out in the third chapter points to the construction of perceptions about migration within Czech society. The absence of gender in the public discourse on migration is further analyzed in the last chapter. The missing gender dimension proved to be...
