In recent years, there has been an increasing number of weather disasters, clearly illustrating the threat of a changing global climate and its consequences to global health.The impacts of climate change are not equal across the world and factors such as socioeconomic conditions and geography play a large role in determining vulnerability to climate-change-related effects. Areas with high population densities, such as cities, have a range of socioeconomic conditions and climate weaknesses that make them susceptible to climate-related harm. This paper outlines the ways that cities can address these challenges and the actions they can take.
