This negatively impacts many aspects of society, including organised sport. As the world’s most watched sporting event, the FIFA World Cup commands particular attention around the threat of extreme heat. The 2022 tournament in Qatar was moved from summer to winter in response to this threat, and now attention turns to the 2026 tournament in North America with extreme heat risk across many of the 16 host locations. We examine this risk by modelling wet bulb globe temperature (WBGT) – a widely used measure of heat stress – for the host locations using hourly meteorological data for the period 2003–2022. Our results show that 14 out of 16 host locations exceed WBGTs of 28 °C, with four (nine) exceeding this threshold more than half the time during afternoons across the mean (hottest year) of the 20 year record. This threshold is important as the level beyond which some football governing bodies recommend match delay or postponement. A climatically sound argument is therefore presented to reschedule kick-off times outside the hottest afternoon hours for the host locations with highest heat risk at which no indoor air conditioned environment exists – primarily Miami and Monterrey, but also Philadelphia, Kansas City, Boston and New York. This study highlights the need to carefully assess heat risk ahead of major sporting events to help inform any potential interventions needed in the scheduling of matches and competitions in a warming climate.</p></div>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":"69 4","pages":"753 - 763"},"PeriodicalIF":3.0,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00484-025-02852-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143035749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To mitigate the challenges posed by heat stress, genetic strategies aimed at reducing feather coverage have gained prominence in hot climate areas. Among these approaches, the naked neck (Na) and frizzle (F) genes have emerged as particularly noteworthy. The Na and F genes play a pivotal role in facilitating heat dissipation and temperature regulation. By decreasing feather insulation, these genes enable efficient heat dissipation through exposed areas of the chickens’ bodies. This reduction in feather coverage leads to elevated body surface temperature, which, in turn, enhances the capacity for heat loss and contributes to overall body temperature reduction. A substantial body of literature underscores the well-established positive impacts of the naked neck and frizzle genes on growth and egg-laying performance. As a result, these genes hold significant potential for integration into broiler and layer production systems, especially in regions characterized by high tropical temperatures. In the context of broiler farming under challenging heat conditions, the Na and F genes have demonstrated favorable effects on crucial parameters such as feed conversion ratio, body weight gain, disease resistance, and carcass attributes. Likewise, layers exposed to elevated temperatures exhibit enhanced egg production, eggshell quality, fertility, hatchability, and resistance to diseases when these genes are incorporated. Given that the prevalence of the naked neck and frizzle genes is primarily observed in indigenous chicken populations, it becomes imperative to prioritize measures for their conservation due to their exceptional performance in heat-stressed environments. To unlock the full genetic potential of exotic poultry reared in hot and humid conditions, the integration of the Na and F genes is a strongly recommended strategy.</p></div>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":"69 4","pages":"709 - 724"},"PeriodicalIF":3.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143035746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most previous studies have examined the health effects of individual pollutants, which often overlook the combined impacts of multiple pollutants. The traditional composite indicator air quality index (AQI) only focuses on the major pollutants, whereas the health risk-based air quality index (HAQI) could offer a more comprehensive evaluation of the health effects of various pollutants on populations. Currently, research on HAQI to evaluate the influence of multiple air pollutants on life expectancy losses is limited. In this study, we employed HAQIto estimate years of life lost (YLL) caused by exposure to air pollution for total deaths and sub-groups by sex, age, and cause-specific disease in Ningbo from 2014 to 2018. Results reveal that significant improvement in air quality during the study period. Based on the AQI-classified air quality risk category, the HAQI estimated a more severe level, which suggests that the commonly used AQI significantly underestimates the hazards of multiple air pollutants. The YLL attributable to exposure above threshold concentrations of the Chinese Ambient Air Quality Standards (CAAQS) 24-hour Grade II standards was 1.375 years (95% CI, 1.044–1.707) per death based on the HAQI, while the YLL estimated using AQI was 1.047 years (95% CI, 0.809–1.286) per death. Females and elderly people over 65 years were vulnerable subgroups, with YLL of 1.232 and 1.480 years per death, respectively.
