Half of the world population and three-quarters of all large cities are located on the coast. 634 million people are at risk from rising water levels. How will our world landscapes change as a result? From New York City to Shanghai, Sydney to Rio de Janeiro—coastal cities have become the nexuses for today's global economy, yet face a confounding duality in which they are also the most threatened by climate change. MIT is addressing these challenges of coastal cities at the 2014 MIT Sustainability Summit. The conference will defy traditional notions of urban development to ask how coastal cities can sustain themselves and continue to grow as the climate changes and their local environments deteriorate.

Register now to learn what the future holds for these cities, what complex problems and exciting solutions exist and what they mean to you and the work you do, and how you can help overcome them to build sustainable coastal cities.
