Cities are vulnerable to the compounding effects of both climate change and urbanization. Here we show that urbanization alone has led to an overall 60% enhancement in warming in Indian cities, with eastern Tier-II cities leading the way. Such a difference in the urban contribution to warming over cities across India calls for a differential approach to combat urban warming effectively. This study looks at nighttime land surface temperature in Indian cities to see how much they have warmed. It finds that urbanization has driven 60% additional warming in cities, with medium-sized cities influencing the most.

Deploying carbon dioxide removal options at the urban scale could not only make a substantial contribution to the global mitigation of climate change but could also have large potential mitigation and adaptation co-benefits. However, upscaling at the global scale is constrained by numerous uncertainties, economic barriers and governance issues.

Animal pathogenic fungi, including human pathogenic fungi, cause millions of deaths annually. We know that these organisms can be found in our urban greenspaces where we enter in contact with them, yet the contribution of socioeconomic development in shaping the distribution of soil-borne animal pathogens from local to global scales remains virtually unknown. Here we used information from a global survey including 56 cities and a high-resolution local survey within Shanghai and found that socioeconomic factors were crucial in predicting the community composition and diversity of soil-borne pathogens. Our results were consistent after accounting for the effects of climate and soil properties. Trichosporon was identified as a universal indicator species for population density at both the global and local scales. Gross domestic product per capita and number of hospital beds were also critical predictors of a limited proportion of Trichosporon in Shanghai. Our study highlights the influence of human activities in shaping the pathogenic microbiome of cities with potential implications for human health, suggesting that poorer and more populated cities are expected to harbor larger proportions of soil-borne animal and human pathogens. Pathogenic fungi, such as Candida, cause millions of human deaths each year. This study found that the soil in urban greenspaces is one source and that socioeconomic factors, such as wealth and medical infrastructure, can predict the diversity and composition of these pathogens in city park soil.

The idea that ‘context matters’ has become a cliché in many scenarios, but it doesn’t make it less true in urban settings: the neighborhood you live in, the way you move through the city, the places you visit, all of these change the way we experience urban life. But context is not only about spaces; it also means people and how we interact with each other. A long commute could be just as lonely whether you are in an empty bus or surrounded by others in rush hour with everyone wearing earphones. This month’s issue puts the spotlight on both parts of the urban experience to paint a more complex picture.

Here, with the aim of supporting the path to achieving net-zero emissions in cities, we assess the existing literature on carbon dioxide removal (CDR) at the urban scale, seeking to quantify the potential negative emissions contribution of cities globally. Urban CDR options considered here include the storage of carbon in urban vegetation, soils and buildings, and the capture of CO2 from indoor environments via decentralized direct air capture. Our estimates of carbon storage and capture potentials indicate that deploying CDR options at the urban scale could make a substantial contribution to global mitigation of climate change, alongside supporting the upscaling of climate action from local to regional and national scale. The associated human and environmental well-being effects strengthen the case for cities as carbon sinks. Any upscale of the reviewed technologies is nevertheless constrained by several uncertainties, economic barriers and governance issues that pose substantial challenges to their implementation. From these, we identify key research gaps and recommendations for future research centered around the need for additional field deployments, consideration of the particularities of different urban geographies and socioeconomic contexts, and the establishment of robust cross-sectoral carbon accounting methodologies. Focusing on the carbon storage potential of urban vegetation, soils and buildings, this Article assesses the literature on carbon dioxide removal at the urban scale. With the prospect of making cities into carbon sinks, the authors identify research gaps and recommendations related to governance, economic barriers and implementation.
