“…EHF (a measure of heatwaves and their intensity) was developed by [66] in the Australian Bureau of Meteorology, and recently augmented by [42,67]. The sequential steps for calculating the EHF are described in detail in these aforementioned studies along with other recent studies [11,68]. Total number of days that contribute to the annual HW events as identified by HWN.…”

Heatwave (HW) number (HWN), frequency (HWF), duration (HWD), magnitude (HWM), and amplitude (HWA) are key aspects for interpreting and understanding HW characteristics worldwide. Most previous HW studies over the Kingdom of Saudi Arabia (KSA) focused only on the temperature extremes, so this study aims to assess the decadal changes, anomalies, and spatiotemporal variations in the five HW aspects over KSA during the last four decades (1982–2021) using the ClimPACT2 software. Daily gridded (0.25° × 0.25°) maximum (TX) and minimum (TN) temperatures from the ECMWF-ERA5 reanalysis dataset were used to compute these heat wave (HW) aspects. The HW aspects were derived in ClimPACT2 using the Excess Heat Factor (EHF), the 90th percentile of TX (TX90), and the 90th percentile of TN (TN90), all based on the reference climate period of 1982–2011. The results showed that the decadal sum and anomaly of the five HW aspects increased gradually during the last four decades (1982–2021). The three indices showed that the maximum decadal sum of HWN (42 events), HWF (255 days), and HWD (145 days) occurred in the last decade. Additionally, the last decade has the maximum decadal sum of HWM (175–463 °C) and HWA (189–471 °C) as derived from TX90 and TN90, which is confirmed by EHF, with ranges of 7–58 and 15–185 °C2, respectively. Finally, the periods 2015–2021 and 1984–1986 recorded the highest and lowest values of annual HW aspects, respectively, across the study period.

“…This is evidenced by an increased risk of heatstroke on the same day by 30.5% when the temperature threshold in Chongqing, China (34 °C) is exceeded by 1 °C, which is almost similar to that in Japan (Akihiko et al, 2014). Other successful examples of mitigation actions that policymakers can promote include developing cooling centres, building cool roofs, providing free access to public pools, creating effective communication strategies with the public, designing effective urban planning, and ensuring adequate food and water security (Broadbent et al, 2020;Çulpan et al, 2022;Hondula et al, 2015). Furthermore, constructing sufficient healthcare facilities and infrastructure, such as beds, power supply, and water and sanitation systems (Li et al, 2015), and preparing adequate human resources is compulsory to ensure sustainability and efficient healthcare.…”

Heatwaves adversely affect human morbidity and mortality, especially in vulnerable groups, and ultimately strain the healthcare system. Prior studies have investigated the impact of heatwaves on healthcare services were conducted in developed countries, which are far superior in terms of financial budget and sophisticated healthcare system compared to developing countries. As a result, the impact of heatwaves on healthcare services in developing countries remains uncertain and inadequately comprehended. Therefore, this systematic review aims to address this gap specifically investigating the impact of heatwaves on healthcare services in developing countries. The study protocol was registered with PROSPERO (CRD42022365471). Primarily, extensive peer-reviewed research was conducted through the Web of Science (WoS), PubMed, and Scopus databases with adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines to collect and characterise key findings from the selected articles related to healthcare systems between January 2002 and April 2023. Subsequently, a thorough quality assessment was conducted using the Navigation Guide checklist. Based on the results, nineteen eligible studies were identified from the search process. Accordingly, it was found that heatwaves significantly increased the rate of Emergency Ambulance Dispatch (EAD), Emergency Department Visits (EDV), hospital admission, and outpatient department visits. Among the identified vulnerable groups severely affected by heatwave events were older people, children, males, outdoor workers, single, and those living in rural areas. Furthermore, various medical conditions were commonly associated with heat-related illnesses that required immediate healthcare services, such as kidney disease, mental disorder, infectious disease, cardiovascular disease, respiratory disease, heatstroke, perinatal, endocrine, nutritional, metabolic and skin problems. For evaluation of Risk of Bias (RoB), approximately 67% of the studies exhibited a 'definitely low' RoB, high quality of evidence (4+), and sufficient strength of evidence on the positive association between heatwave and their impacts on healthcare services. Overall, the duration and intensity of heatwaves showed a direct proportional relationship with the healthcare burden in developing countries. Therefore, policymakers and stakeholders must implement effective preparative planning and preventative efforts to ensure sustainability and efficient delivery of healthcare services, especially by allocating sufficient resources towards improving basic infrastructures and healthcare services.

“…According to the +3.0 • C projection in the sixth evaluation report of Istanbul, via the Intergovernmental Panel on Climate Change (IPCC), temperatures were determined to be above 35 • C for approximately 20 days longer [33]. In the summer months of 2004-2017, 30 heat waves were recorded in Istanbul, and 4281 deaths were detected due to this [34]. In the summer months of 2015-2016-2017 in Istanbul, 419 people lost their lives in 3 extreme heat waves covering a total of 14 days [35].…”

In recent years, a growing body of research has investigated the factors influencing land surface temperature (LST) in different cities, employing diverse methodologies. Our study aims to be one of the few to examine the socio-environmental variables (SV) of LST with a holistic approach, especially in primate cities in developing countries, which are particularly vulnerable to the impacts of climate change. In this context, the study preliminarily identifies the SV of LST while investigating the most vulnerable areas related to extreme LST at the neighborhood level. The combined 11 variables are analyzed using spatial modeling methods (GWR and MGWR). The MGWR model outperforms the GWR model with an adjusted R2 of 0.96. The results showed that: (1) the 65+ population is negatively associated with LST in 95% of neighborhoods; the socioeconomic index–LST relationship is negative in 65% of neighborhoods. (2) In 90% of the neighborhoods where the relationship between LST and the built environment ratio is positive, the socioeconomic level decreases while household size increases in 98% of the neighborhoods. (3) In 62% of the neighborhoods where the relationship between the 65+ population and LST is negative, the relationship between the socioeconomic level and LST is negative. This study aids decision-makers and planners in managing urban resources to reduce extreme LST exposure region by region and recommending multiscale policies to control determinant influences on LST.
