AB  - Non-communicable diseases (NCDs) are a substantial public health concern globally, with environmental factors being dominant contributors. Greenspace, a critical part of our living environment, offers multiple health benefits. However, the impact of greenspace on global NCD burdens remains unclear, hindering the development of effective policies for NCD intervention and greening improvement. Here, we analyzed greenspace-NCD associations across 204 countries/territories during 2000–2021 via mixed-effects regression and estimated preventable NCD-related disease and economic burdens using the comparative-risk-assessment framework. We observed that greater greenspace was linked to fewer NCD-related deaths and disability-adjusted life years (DALYs). Maintaining peak greenspace levels during 2000–2021 could potentially have prevented 1.66 (95% uncertainty interval, 1.32–1.98) million NCD-related deaths and 37.68 (31.27–43.27) million DALYs globally, saving nearly 10 billion US$. These findings reveal greenspace's potential to alleviate global NCD burden, urging policy makers and practitioners to incorporate greening initiatives into NCD management.

AB  - The years 2023 and 2024 were characterized by unprecedented warming across the globe, underscoring the urgency of climate action. Robust science advice for decision makers on subjects as complex as climate change requires deep cross- and interdisciplinary understanding. However, navigating the ever-expanding and diverse peer-reviewed literature on climate change is enormously challenging for individual researchers. We elicited expert input through an online questionnaire (188 respondents from 45 countries) and prioritized 10 key advances in climate-change research with high policy relevance. The insights span a wide range of areas, from changes in methane and aerosol emissions to the factors shaping citizens’ acceptance of climate policies. This synthesis and communications effort forms the basis for a science-policy report distributed to party delegations ahead of the 29th session of the Conference of the Parties (COP29) to inform their positions and arguments on critical issues, including heat-adaptation planning, comprehensive mitigation strategies, and strengthened governance in energy-transition minerals value chains.

AB  - The under-5 child mortality rate remains disproportionately high in low- and middle-income countries (LMICs). Children are particularly vulnerable to high temperatures, and climate change is expected to increase child mortality, yet few studies have investigated the relationship between ambient temperature and child mortality in LMICs. Here, using a sibling-matched case-control design, we examined the association between monthly ambient temperature and under-5 child mortality across 59 LMICs. We found that child mortality increased by 5.2%–10.3% under moderate to extreme temperature (32.0°C –34.9°C), compared to the reference temperature (25.0°C). Our estimates indicate high temperatures contributed to an estimated 5.7 deaths per 1,000 children in LMICs during 2000–2020. This number would increase by nearly 1.5, 2.9, and 3.2 times under the strict-, medium-, and high-emissions scenarios in 2090s, respectively. This study offers insight into the child mortality burden attributable to climate warming across historical and future periods in LMICs, emphasizing the vulnerabilities and inequalities of children in developing nations amid climate warming.

AB  - Short-term exposure to ground-level ozone in cities is associated with increased mortality and is expected to worsen with climate and emission changes. However, no study has yet comprehensively assessed future ozone-related acute mortality across diverse geographic areas, various climate scenarios, and using CMIP6 multi-model ensembles, limiting our knowledge on future changes in global ozone-related acute mortality and our ability to design targeted health policies. Here, we combine CMIP6 simulations and epidemiological data from 406 cities in 20 countries or regions. We find that ozone-related deaths in 406 cities will increase by 45 to 6,200 deaths/year between 2010 and 2014 and between 2050 and 2054, with attributable fractions increasing in all climate scenarios (from 0.17% to 0.22% total deaths), except the single scenario consistent with the Paris Climate Agreement (declines from 0.17% to 0.15% total deaths). These findings stress the need for more stringent air quality regulations, as current standards in many countries are inadequate.

AB  - Black carbon (BC) aerosols play an important role in climate systems. Estimating BC's radiative effect requires knowledge of its mixing state and light absorption enhancement resulting from coatings by other materials. Observational studies have reported much lower light absorption enhancement factors (Eabs) than expected from laboratory studies and model estimates. This has led to an intensive debate on the true magnitude of BC's climate impact. We find that the observed, apparently small Eabs cannot reflect the overall effect of BC coatings, as it does not include the persisting absorption enhancement by extremely low-volatility (eLV) organics that remain on the BC particles after passing through thermodenuders. Our observations show that eLV organics are extensively present in BC coatings, with a mass fraction of-5%-100%. Accounting for these eLV coatings, the observation estimates of Eabs increase substantially to up to 1.8-2.0. Our results highlight a strong radiative warming effect from atmospheric BC.

AB  - Childhood anemia constitutes a global public health problem, especially in low- and middle-income countries (LMICs). However, it remains unknown whether global warming has an impact on childhood anemia. Here, we examined the association between annual temperatures and childhood anemia prevalence in sub-Saharan Africa and then projected childhood anemia burden attributable to climate change. Each 1°C increment in annual temperature was associated with increased odds of childhood anemia (odd ratio = 1.138, 95% confidence interval: 1.134-1.142). Compared with the baseline period (1985-2014), the attributable childhood anemia cases would increase by 7,597 per 100,000 person-years under a high-emission scenario in the 2090s, which would be almost 2-fold and over 3-fold more than those projected in moderate- and low-emission scenarios. Our results reveal the vulnerabilities and inequalities of children for the excess burden of anemia due to climate warming and highlight the importance of climate mitigation and adaptation strategies in LMICs.
