urban climate and adaptation tools

The immediate threat climate change poses to our common future requires that we fully reconsider the ways in which humankind interacts with the environment. Cities and their development should be considered one of the most relevant issues considering that within the next few decades most of Earth's population will live inside city boundaries. The recent IPCC Special Report focused on the politics and mitigation strategies by which warming could be kept to within 1.5 °C. The most important chapter considered the actions, enforced by the Covenant of Majors, seeking to secure both population and production in the event that mitigation policies fail to be applied. The word that summarizes this approach is 'resilience'--the capability of a system to recover from strain. To build more resilient cities, knowledge must be shared by numerous intersecting disciplines and policy makers via networks such as C40. It is vital to advance our knowledge of the following topics: urban climate, the interaction between climate and meteorology in the urban structure, the possibility to apply climate services (recently, the WMO urban guide) to create auto-regenerative solutions in the city structure, and the capability to transform projects from the paper to the city itself. This Special Issue aims to investigate the state of the art connections between the various disciplines involved in urban transformation and to understand if a common language already exists.
