Urban agglomerations have recently become the main habitat for humans on the planet Earth, and the trend towards life in cities and its peripheral regions is continuing. Change in climate, higher frequency of extreme weather events, environmental pollution, population growth, the increase in water demand, and the decrease in biodiversity have profound effects on the habitat conditions in cities and consequently on human well-being.

On the other hand, the growing cities themselves modify and sometimes amplify many of the processes mentioned above. The concentration in population, pollution, energy and resource usage offers the chance for effective adaptation and mitigation measures.

The session invites contributions covering the topics outlined above of urban systems and the climate, particularly:

• Numerical models of urban agglomerations of different complexity
• studies on interactions between climate change effects and urban agglomeration
• effects of urbanisation on the earth system
• climate change and human health in an urban context
• air and light pollution in urban systems
• urban water fluxes and urban metabolism under changing climatic conditions
• urban air pollution
• climate change adaptation and mitigation strategies in an urban environment
