Climate Change in Global Cities

Scientific studies have found it to be unequivocal that human activities are causing climate change. Global warming is a result of processes in the atmosphere and oceans, for which the governing equations are relatively well known. Hence, by conducting climate simulations using supercomputers and cutting-edge prediction models, the magnitude of future warming can be quantitatively predicted with a certain degree of error. Such predictions are fundamentally important for many fields, including the future design of food-energy-water processes and political decisions. Predictions show that the future impact of global warming will differ in each city. This chapter introduces how predictions are conducted, limits to the use of data, and differences among cities in the impacts of global warming.
