UCCRN Assessment Reports on Climate Change and Cities (ARC3 Series)

The Urban Climate Change Research Network (UCCRN) is a global consortium of individuals and institutions dedicated to the analysis of climate change mitigation and adaptation from an urban perspective. Based at Columbia University’s Earth Institute, the Network is designed to enhance cutting-edge scientific, economic and planning-related research and to promote knowledge-sharing among researchers, decision-makers, and stakeholders about all aspects of climate change and cities. UCCRN aims to institutionalize a sustained, state-of-the-knowledge assessment process of climate change science tailored for urban needs, drawing on the experience of cities across the world as they act to adapt to and mitigate the impacts of climate change.

The ARC3 report series represents an effort by over 400 authors from cities in developed and developing countries around the world. The reports are the first-ever global, interdisciplinary, cross-regional, science-based assessments to address climate risks, adaptation, mitigation, and policy mechanisms relevant to cities. The Second Assessment Report (ARC3.2), to be published in 2017, presents downscaled climate projections and catalogues urban disasters and risks, along with the effects on human health in cities. ARC3.2 gives concrete solutions for cities in regard to mitigation and adaptation; urban planning and design; equity and environmental justice; economics, finance, and the private sector; critical urban physical and social sectors such as energy, water, transportation, housing and informal settlements, and solid waste management; and governing carbon and climate in cities. Other key topics include ecosystems and biodiversity, and urban coastal zones.
