The Climate Security Nexus
The progression of climate change impacts in the age of the Anthropocene will have dire consequences for our planet; yet, will it also bring about greater violence and conflict? The linking of climate change to violent conflict or the climate-security nexus (C-S nexus) was popularized in 2003 with the release of two security strategies from the Pentagon and the European Council. This idea gained momentum when, in 2007, the Nobel committee awarded the Nobel Peace Prize to Al Gore and the Intergovernmental Panel on Climate Change (IPCC) for their work at raising the world’s awareness of anthropogenic climate change. Scientists contributing to this dialogue took reference to the literature and theories of the environmental security debate, and much scholarship has ensued since. Although most empirical work has found no causal link between climate change and violent conflict, several quantitative studies have shown otherwise. A large majority of literature, however, focuses on the conditionalities of climate change on broader elements of human security and finds the proposed relationships to be neo-Malthusian and environmentally deterministic. The strength of this critique has resulted in wide disagreement of the validity of the C-S nexus—from those who recognize it as an important way to promote climate change mitigation to those that warn that such discourses serve an agenda for greater hegemony and militarized control of the Global South. These arguments, as well as their potential for policy response, are highlighted in this article through a body of literature that explains both how and why the C-S nexus is being discussed and the consequences to this and other securitization debates.
