Summary: The study on heat islands in Ahvaz, Iran, from 1995 to 2016, showed significant changes in land use and a worsening urban heat island phenomenon. Results indicated that areas with bare land and residential development were the hottest in Ahvaz, while a reduction in green space led to an intensification of the UHI.

Summary: This study assessed the cooling effects of small greenspaces (SGs) and building-shaded spaces (BSs) in urban areas, finding that SGs had a greater impact on reducing heat compared to BSs, especially in blocks with larger greenspace. Additionally, SGs provided the greatest microclimatic benefits in the largest blocks, highlighting the importance of block size in determining cooling degrees.

Summary: This study investigates the spatiotemporal characteristics of the urban-rural near-surface air temperature difference in Beijing, known as the canopy layer urban heat island (UHI). By using simulations and sensitivity analyses, the study quantifies the relative impacts of surface properties and anthropogenic heat emissions on the temporal variation of Beijing's UHI. The results show that while anthropogenic heat emissions dominate the nocturnal UHI in winter, the model underestimates the effects of local heat sources in summer, indicating the need for higher-resolution anthropogenic heat emission data.

Summary: Urban heat island effect can be triggered by climate change and rapid urbanization, leading to higher temperatures in urban areas compared to rural areas. The study in Kolkata municipality explored land use changes, land surface temperature analysis, and correlations between various factors like LST, LULC, NDVI, and NDBI. Proper planning is needed to address future urban expansion and environmental degradation for better livelihoods and protection of the environment.

Summary: In recent decades, large-scale urbanisation has led to a significant urban heat island (UHI) effect in Athens, with temperature rise of up to 4 degrees Celsius on average and even reaching 8-9 degrees Celsius at times. High-resolution WRF simulations were used to study the spatiotemporal variability of the UHI phenomenon, and different meteorological conditions, including an extreme heat wave, were investigated.

Summary: This research uses three dynamically downscaled regional climate models (RCM1 - RCM3) and two representative concentration pathways (RCP4.5 and 8.5) to project future climate change-induced urban heat island (UHI) trends (2022-2099). The findings reveal that the Bangkok metropolitan area is highly likely to experience warmer temperatures in the future, contributing to higher land surface temperature and UHI intensity.

Summary: With rapid urbanization, the urban heat island (UHI) effect is becoming more pronounced. This study focuses on identifying and evaluating the temporal-spatial variations and driving factors of UHI in Changchun city, Jilin province, in Northeast China. By utilizing satellite images and ancillary data, this study analyzes the variations of UHI effect over time and space, as well as its relation with urban development. The findings reveal the temporal variations of UHI based on air temperature and the spatial variations of UHI based on land surface temperature. The study emphasizes the importance of urban land planning for mitigating UHI effect and promoting sustainable urban development.

Summary: Due to urbanization, irregular urban topography negatively affects urban climate and leads to the formation of urban heat islands. This study used remote sensing methods and satellite/terrain data to analyze the spatial and temporal distribution of potential urban heat islands in Diyarbakir province, Turkey. The results show that the area with potential heat islands has increased over the years, and the areas with the highest potential are located near the city center and in topographically hollow areas.

Summary: This article presents the first country-wide study of the Surface Urban Heat Island (SUHI) in Romania, focusing on cities with a population of over 30,000 people. The study uses MODIS Land Surface Temperature (LST) data to examine the relationship between air temperature and LST, temporal variations in LST in urban areas, and the intensity of the SUHI across the country. The results indicate that there are significant differences between night-time and day-time conditions, and seasonal biases are observed. The findings show that city size, climate type, and land use-land cover conditions contribute to the magnitude of the SUHI in Romania.

Summary: This study examines the impact and mechanism of the Winter Clean Heating Plan for Northern China on air pollution reduction. The research finds that the policy has effectively reduced air pollution emissions in the northern region by 17.3% since its implementation. Economic and urban development factors also play a role in reducing air pollution. The results indicate that the policy has a more significant positive influence on air pollution control in Northwest China's cities and non-provincial capital cities.
