Climate risk is underpriced in US municipal bonds, creating vulnerabilities as insurers retreat and adaptation planning remains disconnected from finance. This Review reveals a climate-debt doom loop and proposes governance reforms and disclosure standards to strengthen municipal resilience.
Urban digital twins rely on static sensors and miss dynamic human and socioeconomic dimensions. Integrating anonymized mobile crowd data provides real-time, context-rich insights that improve accuracy, responsiveness and citizen co-creation.
Climate change is making walking in cities more difficult. This Review examines the connection between climate change and walkability, focusing on thermal comfort in complex urban environments.
Text has traditionally been used as a qualitative resource in urban research, but new tools enable large-scale quantitative analysis. This Review explores the opportunities and challenges of using text data to generate insights into cities.
Cities affect biological evolution, but traditionally researchers focus on the biophysical influence of urban environments. Instead, this Review explores how the social processes of religion, politics and war drive wildlife evolution by shaping urban conditions.
Forests help to sustain cities and all who live in them. This Review considers barriers to sustaining resilient forests and suggests paths for overcoming them.
Using five infrastructure sectors (transportation, energy, health, utilities and governance), this Review pays attention to the mechanisms through which smart dimensions of cities operate in terms of how information flows from the device to the decision.
This Review explains the advances in complexity science for smart cities, showing how the logic of this field can be applied to increasingly complex features of cities.
This Review makes the case for enhancing indoor air quality through indoor CO2 capture and describes how technological advances in materials and chemistry enabled these improvements. New constructions or retrofitting buildings would allow these advances to be implemented to improve CO2 capture.
Local governments have formed city networks to face the climate emergency by bridging borders and geopolitical differences since at least the 1990s. This Review shows what has been achieved in these three decades, and indicates the importance of improving the inclusiveness, recognition and reach of these city networks going forward.
This text defines vertical segregation and its importance for urban studies and for cities more generally. It brings some case studies from Athens and other cities in the world to illustrate how this type of segregation appears.
This article critically reviews the literature on the politics and government of cities, from classical contributions to contemporary debates in sociology, political science, development studies and other social sciences.
Humanity is increasingly urban, but urban living is not new, and past examples showcase striking variation. This Review synthesizes methodological and other advances in archeology to illustrate how compellingly the past can inform current urban science and understanding.
