Abstract Heatwaves pose significant threats to socioeconomic and environmental systems, with their intensity frequency expected increase due climate change. Despite critical impacts, future heatwaves in Brazil remain underexplored, especially from a human-perceived perspective, which is crucial for assessing potential public health impacts. Here, we propose method assess using the humidex ( H )—a index that combines temperature relative humidity indicate heat - alongside traditional temperature-based measures. Using bias-corrected simulations 10 CMIP6 models under SSP2-4.5 SSP5-8.5 scenarios, quantified projected changes across Brazil. The results will become more severe prolonged, greater scenario by end of century, particularly North, Northeast, Central regions. magnitude rise faster than ones, underscoring need health-focused assessments. strongly agree on increased heatwaves, potentially tripling population exposure most Brazilian states, Southeast experiencing its larger population.

Under climate change, China faces intensifying compound extreme events with serious socio-economic ramifications, yet their future variations remain poorly understood. Here, we estimate historical hotspots and changes of two typical events, i.e., sequential heatwave precipitation (SHP) concurrent drought (CDH) across China, leveraging a bivariate bias correction method to adjust projections from global models. Results show substantial increases in frequency, duration, magnitude for both the durations projected double nationwide. The are more evident under higher emission scenarios, could be largely underestimated if neglecting variable dependence during process. will escalate exposure China's major urban clusters, among which Guangdong-Hong Kong-Macao face highest risk. Our findings underscore necessity carbon controls, call adaptive measures mitigate threats induced by rising hazards changing climate.

ABSTRACT The concurrent occurrences of drought and extreme heat events, such as heatwaves, present substantial threats to human health ecosystems. This study delves into a thorough examination the collective impacts events in Southeast Asia (SEA) over past 83 years (1941–2023). Two primary definitions guided investigation: Compound Drought Heatwave Events (CDHW) Hot Droughts (CHD). Wet‐Bulb Globe Temperature (WBGT) was employed define heatwaves hot while Standardised Precipitation Evapotranspiration Index (SPEI) used for definition. In addition, explored impact linear detrending on copula fitting, assessing its effects. findings consistently revealed strong positive correlation between CDHW. On other hand, CHD exhibited varied patterns across regions. Furthermore, highlighted that had lower sensitivity CDHW compared CHD. analysis uncovered significant regional disparities joint return period ranking compound stemming from diverse approaches. Particularly non‐continental SEA, notably some regions like Sumatra Island, noteworthy distinction emerged, indicating limited applicability scenarios with stringent concurrence events. These insights provide valuable assistance research community, aiding discernment distinctions heat‐event assessment.

ABSTRACT In September 2024, the Yangtze River basin experienced a supremely extreme heatwave that broke historical records from at least 1961 and could have severe impact on outdoor health of school children. This paper provides timely analysis characteristics in its exposure to population aged 14 years below, causes led occurrence, as well future projections. regional average days reached 7.57 days, daily maximum temperature ( T max ) 31.53°C, both which are much higher than climatology exceed records. resulted high under, with provinces Sichuan, Chongqing, Hunan, Jiangxi exposed more 100 million person‐days. The expansion South Asian High (SAH) Western Pacific Subtropical (WPSH) may directly contributed this heatwave. CMIP6 projections show frequency heatwaves similar 2024 will increase future.

Human-induced landscape modifications and climate change are forcing wildlife into closer contact with humans as the availability of natural habitats decreases. Although importance anthropogenic structures for conservation species is widely recognized, negative narratives surrounding bats may impede efforts in human-dominated landscapes. We conducted a global systematic literature review to summarize research pertaining analyze impacts occupancy these on humans. extracted data from 735 publications included 8 that provided total 29 quantitative estimates meta-analyses assessing consequences roost selection by habitats. Additionally, information all was used summaries. Research focused Northern Hemisphere, despite highest diversity bat occurring near equator. Of 13 identified use structures, disturbance (caused by, e.g., visitation, renovations, artificial lighting) most frequently reported. Effects presence were primarily associated pathogens or other microorganisms zoonotic interest. Buildings roost, buildings differed across biogeographic realms. varied realms Nearctic Palearctic had incidence impacts. Few studies compared roosts roosts, but our broadly differences effects versus behavior, temperature, health occupancy. found not currently areas where bat-human interactions likely intensify growing rate urbanization. many roosting documented mentioned, did measure few them roosts.

Abstract Ensuring crop yield stability is crucial for food security in Africa, where agriculture faces increasing demand amid considerable vulnerabilities. Remote sensing and reanalyzed data products offer the potential capturing growth dynamics understanding their drivers. However, impacts of cropland masks on relative anomalies (RYA) contributions variables across Africa crops remain unclear. This study explores explanatory power air land surface temperatures (AT LST), precipitation, evapotranspiration, soil moisture maize, millet, sorghum RYA 2001–2020 under seven with distinct configurations temporal, type, water supply systems. Results indicate that (a) North was particularly affected by variation West strongly impacted Central East were highly influenced mean AT total South mainly high LST, precipitation variation. (b) Interactions between LST improved multiple stepwise regression model from 67% to 73%, while random forest considering complex variable interactions reached 83%. (c) Variables less choice masks. Mask broader coverage compensated limitations temporally static masks, type identification enhanced when using year‐specific crop‐specific maps. Future research should integrate process‐based models better understand mechanisms behind diverse drivers at regional scale Africa.
