本文综述了与极端天气事件和自然灾害相关的地球物理和气候趋势、其对城市地区的影响以及城市扩张造成的持续环境改变的影响。它讨论了城市设计、技术发展和社会行为如何能够减轻或加剧城市地区气候引起的灾害。压力-从导致城市洪水的过多降雨到导致空气污染的城市极端气温-需要更多地关注了解、模拟和预测城市地区灾害的变化。它的结论是，涉及不同的技术数据分析和系统建模是更适合于实际的决策比纯粹的简化的方法。然而，要成功地确定特大城市的未来环境，就需要在健全的科学成就基础上，与了解社会情况的决策者共同采取行动。
This paper is a review of geophysical and climatic trends associated with extreme weather events and natural hazards, their implications for urban areas and the effects of continued environmental modification due to urban expansion. It discusses how urban design, technological development and societal behaviour can either ameliorate or worsen climate-induced hazards in urban areas. Pressures - ranging from excessive rainfall causing urban flooding to urban temperature extremes driving air pollution - require more attention to understand, model and predict changes in hazards in urban areas. It concludes that involving different techniques for data analysis and system modelling is more appropriate for practical decision-making than a purely reductionist approach. Successfully determining the future environment of megacities will, however, require joint action with societally informed decision makers, grounded in sound scientific achievements.
