This study explores Trump's narrative on climate change and exposes how official discourses had an impact on the policy level change under the Trump administration. Firstly, this study shows that the Trump administration in its three-plus years proved to be the worst denier of climate scientific projections and deregulated almost all the domestic climate control laws and withdrew from the Paris agreement. Secondly, this study highlights the role of discourses in manufacturing favorable consent from the public to make national security decisions more legitimate. Moreover, the US is the second-largest and number-one historic carbon polluter in the world. President Trump ended the ‘war on coal’ and transformed the US energy generation towards fossil fuels such as coal, oil, and natural gas. In addition, such implementations by one of the biggest industrialized states in the world had disrupted the efforts of the international community to limit the potential threat to humanity and ecosystems.
