The organisation has successfully securitised climate change since 2008, prioritising it on the policy agenda. This securitisation has been established through speech acts defining climate change as a threat. This thesis examines the security narratives invoked in European Parliamentary debates from 2005 to 2011, focusing on the different security framings of climate change as a threat, and how these have changed over time. It argues that before the securitisation of climate change, the European Parliament framed climate change predominantly through ‘low politics’ security narratives like cooperative, environmental, and human security framings. Remarkably, this did not change after the securitisation of climate change, while it was expected that ‘high politics’ security narratives like global and national security would be more dominant. Ultimately, this thesis shows that when addressing climate change, the European Parliament frames the issue as a threat primarily through ‘low politics’ narratives, both in the three years before and the three years after the successful securitisation of climate change.Show less
