 The First Assessment Report on Climate Change and Cities (ARC3)was launched by the Urban Climate Change Research Network (UCCRN) in November 2008 at a major workshop in New York City, with the goal of building the scientific basis for city action on climate change. Eventually more than 100 lead and contributing authors from over 50 cities around the world contributed to the report, including experts from cities in both the developing and developed world, representing a wide range of disciplines. The book focuses on how to use climate science and socio-economic research to map a city’s vulnerability to climate hazards, and how cities can enhance their adaptive and mitigative capacity to deal with climate change over different timescales.Editors:
