In the late 2000s climate action became a defining feature of the international political agenda. Evidence of global warming and accelerating greenhouse gas emissions created a new sense of urgency and, despite consensus on the need for action, the growing failure of international climate policy engendered new political space for social movements. By 2007 a ‘climate justice’ movement was surfacing and developing a strong critique of existing official climate policies and engaging in new forms of direct action to assert the need for reduced extraction and burning of fossil fuels. Climate Action Upsurge offers an insight into this important period in climate movement politics, drawing on the perspectives of activists who were directly engaged in the mobilisation process. Through the interpretation of these perspectives the book illustrates important lessons for the climate movement today. In developing its examination of the climate action upsurge, the book focuses on individual activists involved in direct action ‘Climate Camps’ in Australia, while drawing comparisons and highlighting links with climate campaigns in other locales. The book should be of interest to scholars and researchers in climate change, environmental sociology, politics, policy and activism.
