Abstract Cities worldwide are increasingly committing to achieving net-zero carbon emissions in the coming decades. Most cities not yet aware of drastic changes built environment required reduce GHG emissions, and many cases neutrality targets will require atmospheric removal outside or within city boundaries offset remaining emissions. Since particularly affected by increasing temperatures (e.g. due urban heat island effect), direct regulation radiation through surface albedo management has also been suggested alleviate these exacerbated impacts. With aim supporting path carbon-neutral cities, this paper assesses existing literature on Carbon Dioxide Removal (CDR) at scale, seeking quantify potential negative contribution globally. Our estimates indicate that deploying CDR options scale could make a significant global mitigation climate change, alongside upscaling action from local regional national scale. The associated human environmental well-being effects strengthen case for as sinks. upscale reviewed technologies is nevertheless constrained numerous uncertainties, economic barriers governance issues pose substantial drawbacks their implementation scope, suggesting future research agenda.

Abstract Urban populations face heightened extreme heat risks attributed to urban islands and high population densities. Although previous studies have examined global exposure heatwaves, the influence of urbanization-induced warming is still not quantified. Here, leveraging satellite-derived near-surface air temperature data, we assess impacts on in 1028 cities worldwide. Additionally, investigate its role shaping disparities between North South cities. Our findings reveal that urbanization-amplified compound heatwaves exacerbate risk more than 90% cities, this amplification stronger urbanization areas. Moreover, our analysis highlights potential for overestimating if overlooked. The inequality higher will be narrowed real scenarios due intense We emphasize pivotal heatwave intensification assessments call inclusion future vulnerability evaluations heat.

Significant urbanization resulted in increasing surface urban heat island (SUHI) that caused negative impacts on ecological environment, and residential comfort. Accurately monitoring the spatiotemporal variations understanding controls of SUHI were essential to propose effective mitigation measurements. However, grades across global cities remained unknown, which cloud greatly support for mitigations. Additionally, quantitative evaluating factor weights different indicators worldwide further investigations. Therefore, this paper proposed grading based agglomerative hierarchical clustering, quantified an interoperable machine learning named TabNet. There three major findings. (1) Global grouped into five grades, including SUCI (surface cool island), insignificant, low-value, medium-value, high-value indicating significant differences among grades. showed climate-based variations, wherein arid climate was dominated by grade at daytime but nighttime.
