Cooling the planet by urban restructuring

There is a wide scientific consensus about the current and seemingly invariably on-going climate change, the global warming. Moreover, it is becoming evident that even quite novel technological innovations (like CCS utilising biomimicry) and equivalent rapid measures cannot turn the trend until next ten or twenty years. The debate is now more and more turning to the mitigation of its probably serious consequences on the urban development and the whole human culture. The increased number and magnitude of heat waves, storms, flooding, sea level rise etc. are followed by loss of economic values as well as degradation of production power. All this might give reasons to new types of migratory movements, maybe even territorial fights for vital resources (like clean water and air, food and certain materials needed in the industrial processes). If this dystopia is going to happen, it calls for restructuring and reorganisation of the whole urban system. We should assess different roadmaps and scenarios.
We need tools capable for assessing the urban eco-efficiency and especially the carbon footprint on local and global levels both linked with the systemic behaviour and dynamics of urban development. This could pave the way to global cooling.
