Human settlements need to be prepared for climate change impacts like extreme heat and flooding. Urban planners and architects must consider climate extremes, economic growth, and livability to create resilient cities. Public awareness and environmental justice are driving the discussion on urban climate change ethics. By using a data-driven design approach, communities can balance environmental justice, climate needs, and economic development. Proper design and planning can help cities manage vulnerabilities and become more resilient to climate extremes. Urban designers and planners need to adopt a holistic approach to urban climate science to guide development strategies and environmental regulations in an interconnected world.
