"This thought-provoking book explores how the global ecological crisis profoundly challenges conventional meanings of environmental security and raises important questions about how states and other institutions now face the future. Simon Dalby provides unique insights into the traditional search for security in terms of using firepower to dominate states and environments, and how this is now endangering people across the globe. Whereas earlier concerns about nuclear firepower focused on the security dilemmas it posed, Dalby offers a new perspective into the existential threats to civilization presented by the combustion of fossil fuels. Propounding that the constraint of firepower in both senses is now key to a flourishing human future, the book calls for international relations scholars to rethink many of the central premises in the field and formulate new policies that focus on the necessity of ecological flourishing to provide meaningful security in a climate disrupted world.Visionary and inspiring, Rethinking Environmental Security will be a critical read for scholars and students of international relations, climate change, environmental governance and regulation, and political geography and geopolitics. Its novel ideas will also be beneficial for policy makers and practitioners in these fields."--Back cover

Climate change and the responses to it reveal starkly different assumptions about borders, security and the ethical communities for whom politicians and activists speak. Starting with the contrasting perspectives of international activist Greta Thunberg and United States President Donald Trump on climate change this essay highlights the diverse political assumptions implicit in debates about contemporary globalization. Rapidly rising greenhouse gas emissions and increasingly severe climate change impacts and accelerating extinctions are the new context for scholarly work in the Anthropocene. Incorporating insights from earth system sciences and the emerging perspectives of planetary politics suggests a novel contextualization for contemporary social science which now needs to take non-stationarity and mobility as the appropriate context for investigating contemporary transformations. The challenge for social scientists and borders scholars is to think through how to link politics, ethics and bordering practices in ways that facilitate sustainability, while taking seriously the urgency of dealing with the rapidly changing material context that globalization has wrought.
