The New Climate Calculus: 1.5°C = Paris Agreement, Cities, Local Government, Science and Champions (PLSC2)

Abstract

The 2015 Paris Agreement is an important step forward in developing a shared and equitable global climate change response that has the possibility of limiting global temperature increase to 1.5°C above pre-industrial levels. Its long-term success, however, depends on the extent to which the goals and aspirations of the agreement (and accompanying decision text) are implemented. Cities offer a global scale opportunity to ‘bend the climate curve’ through ambitious mitigation and transformative adaptation actions. This is an opportunity that can only be realised if local governments help create a shared vision of low-carbon and climate resilient cities that improve health and well-being, provide ways to meet basic needs, create jobs, ensure environmental sustainability, foster economic opportunities and promote equity. The successful implementation of this vision requires a new type of city science that integrates natural and social sciences with grounded practice, and does not shy away from savvy politicking and passionate activism. It will also depend on champions at all levels, working across institutional boundaries to sustain action and increase momentum over time.
