Climate change continues to present challenges in both urbanism, technological innovation, and smart design. The role of global smart cities and AI is crucial in addressing this issue. This nexus empowers city planners and policymakers to leverage data-driven insights for sustainable development, enhancing our resilience against environmental impacts while improving the quality of urban life. Urban architecture, migration, microplastics, environmental changes, and air pollution are among the significant contributors to climate change, and effective solutions through international collaboration have become increasingly important. Finding solutions for climate change through smart urbanization, AI, and mapping, among other technologies, is necessary to implement effective change for a greener, sustainable future. Nexus of AI, Climatology, and Urbanism for Smart Cities explores the impact of intelligent technologies on the environment and urban development. The intersections of climatology, AI, and urbanism for smart city development are examined with strong emphasis on effective solutions for new climate policies, architectural design, engineering sustainability, and green transportation. This book covers topics such as assistive technology, smart governance, and water management, and is a useful resource for computer engineers, climatologists, environmental scientists, urban designers, business owners, policymakers, researchers, and academicians.
