This study finds that high levels of air pollution in India, including in rural regions, are significantly associated with respiratory illness in young children, a significant source of childhood morbidity and mortality. 

Global climate overshoot scenarios rely heavily on land-based carbon dioxide removal (CDR), but the IPCC’s optimistic technical and economic potentials overlook the unquantified “feasible” potential shaped by socio-cultural, environmental, and institutional factors. This article proposes research frameworks to quantify this feasible potential, urging caution in using techno-economic CDR assessments for policymaking.

Climate change adaptation is urgent, yet understanding which strategies effectively reduce risks across varied climate conditions remains limited. By analyzing climate variability features and community responses—illustrated through an African case study—this review offers insights and methods to engage communities and inform policymakers for more effective adaptation support.

An overshoot of the 1.5°C target seems inevitable, prompting urgent calls for comprehensive, interdisciplinary, and globally coordinated solar geoengineering research. Drawing lessons from the CGIAR agricultural network, this article proposes a global network of climate action centers to ensure reliable and legitimate research, guiding policymakers and donors in addressing this critical need.

Steel production is a major global carbon emitter, yet its role in meeting climate targets remains underexplored. Our analysis shows deep emission cuts are achievable through rapid mitigation, demand reduction, and carbon capture, offering vital guidance for policymakers and stakeholders in decarbonization planning.

Recent advances in nanotechnology have generated concerns regarding nanoparticles' prevalence, dispersion, destiny, and environmental migration. Nanoparticles originate from diverse sources, such as their extensive utilization in various engineering practices, biomedical uses, consumer products, and food and drug delivery systems. Nanoparticles and nanoscale materials are increasingly found in multiple environmental media, often released as waste or by-products from engineered processes.

Since 2016, there have been significant developments in agrivoltaic farming and the role of solar energy harvesting. The use of agrivoltaic farming applications differs between various countries due to challenges such as technical and economic ones. A short description of various solar panels has been presented. It discussed plant parameters for agrivoltaic system use, an especially possible role of light saturation point. Technical parameters for optimization of agrivoltaics—how various heights, spacing, impact of density the shading under the panels.

The 2025 winners of the RELX Environmental Challenge, which supports innovative solutions to advance SDG 6 Clean water and sanitation, have been announced.
