Article Abstract
Anthropogenic climate change is driving summer heat toward more humid conditions, accompanied by more frequent day-night compound heat extremes (high temperatures during both day and night). As the fast-warming and aging continent, Europe faces escalating heat-related health risks. Here, we projected future heat-related mortality in Europe using a distributed lag nonlinear model that incorporates humid heat and compound heat extremes, strengthened by a health risk-based definition of extreme heat and a scenario matrix integrating time-varying adaptation trajectories. Under 2010-2019 adaptation baselines, future heat-related mortality is projected to increase annually by 103.7-135.1 deaths per million people by 2100 across various population-climate scenarios for every degree of global warming, with Western and Eastern Europe suffering the most. If global warming exceeds 2 °C, climate change will dominate (84.0-96.8%) projected increase in heat-related mortality. Across all socioeconomic pathways, even a 50% reduction in heat-related relative risk through physiological adaptation will be insufficient to offset the climate change-driven escalation of future heat-related mortality.

Heat-Health Action Plans (HHAPs) are essential public health interventions to reduce heat-related mortality and morbidity, yet how heat-related health risks have changed following their implementation remains scarce. This study aimed to examine the temporal changes in heat-related mortality in relation to the implementation of the HHAPs across five major cities of Australia, including Melbourne, Sydney, Brisbane, Adelaide, and Perth. Daily mortality and temperature data from 1999-2019 were analysed using distributed lag non-linear models to compare the heat-related mortality attributable fractions (AF%) between pre- and post-HHAP periods.

Background: Although climate change poses increasing risks to child health, particularly through temperature extremes, epidemiological evidence on its impact on child mortality is still limited. This study investigated the short-term effects of ambient temperatures (heat and cold) on under-five mortality in Brazil.
Methods: We conducted a space-time-stratified case-crossover study across 5570 Brazilian municipalities from 2000 to 2019, using data from the Brazilian Mortality Information System and from the Brazilian Daily Weather Gridded Data (BR-DWGD).

Background: The rise in hot nights over recent decades and projections of further increases due to climate change underscores the critical need to understand their impact. This knowledge is essential for shaping public health strategies and guiding adaptation efforts. Despite their significance, research on the implications of hot nights remains limited.

Infants are at a higher risk of heat-related morbidity and mortality compared to children and adults. However, it remains unclear whether this vulnerability stems from immature thermoregulatory mechanisms or simply from their dependence on caregivers. This narrative review examines current literature on infant thermoregulation during heat exposure and explores how unique physiological characteristics may influence vulnerability.

Purpose Of Review: Heat Health Warning Systems (HHWS) reduce heat-related morbidity and mortality. We reviewed scientific studies on HHWS that use meteorological variables, local climate-epidemiological evidence, personalization, and built environment factors to determine heat stress thresholds. We identified key factors to enhance their precision and effectiveness.
