The City not only defines itself as a generator of cultural, social, economic and ecological processes, but also as a seismograph of global developments. Climate change and its impacts, present new challenges for cities, which in Hamburg have guided a re-evaluation of necessary activities in this regard. In 2011, as "European Green Capital", Hamburg will be designated Climate Capital of Europe. The Seismograph City exhibition gives a fascinating view of the current status of the architectural and urban planning development of this Hanseatic city, in dialogue other cities and countries worldwide.
