“…This result has also been confirmed in many regional climate change studies 41,42 . The results of the correlation analysis also show that vegetation cover, air humidity, and distance from water bodies can significantly regulate surface temperature, which is similar to the findings of many studies on urban thermal environments [43][44][45][46] . Therefore, managers need to pay more attention to the protection of the ecological functions of wetlands and rice paddies and implement ecological restoration projects under the concept of the community of life of mountains, water, fields, lakes, grass and people.…”

the Dongting Lake area (china) is a climate change-sensitive and ecologically fragile area and plays a crucial role in the regulation of the regional climate. in recent decades, rapid social and economic development has led to increased land use/land cover (LULc) changes in the Dongting Lake area, which affect the surface energy balance and hydrological processes. Its contemporary variability under climate change remains highly uncertain. therefore, we retrieved the Land surface temperature (LSt) from the Landsat 7 data and explored its relationship with the LULC types. The results showed that LST is significantly affected by surface type. LST varied significantly across LULC types, with higher LSTs in built-up land, reed beach land, forest land, and paddy fields than in water bodies, mud beaches, marshlands, and riparian forests. Water bodies play an important regulatory role in reducing LSt and mitigating thermal effects on the ground. The winter LST in the study area increased by approximately 3.5 °C, which may be related to the decrease in the area of Dongting Lake water bodies, water fields and reed flats after the Three Gorges Reservoir was impounded. Compared with the relationship between the nDVi, DeM, and distance from the water body, the negative correlation between the nDMi and LST was stronger and more stable and had the greatest effect on LST. These insights improve the understanding of the land change consequences on the temporal dynamics of LSt. Land surface temperature (LST) is a reflection of the energy flow in the interactions between the land surface and atmosphere and between the land surface and biosphere. The change in LST is an intuitive regional climate response to global climate change and has important research significance in agriculture, hydrology, ecology, environment, climate, and biogeochemistry1 1-6. LULC is the interface between the atmosphere and biosphere for material and energy exchange and has a clear influence on LST. Currently, a wide consensus has been reached on the influence of LULC change on regional climate through various processes, such as water and heat flux between land and air 7 , surface wind speed, and boundary layer turbulence8 8,9. Exploring the mechanism of interaction between LULC change and local climate has become a popular research topic 10-12. LULC change directly causes changes in the physical characteristics of the land surface, which affects a variety of factors that determine regional climate, such as radiation, heat, and water vapor exchange 13-15. LULC change also alters the composition of surface attachments such as vegetation type and vegetation density 16,17. In addition, LULC change has associated effects such as demographic changes and changes in regional chemical composition 18,19. This relationship has led to changes in terrestrial carbon stocks and their fluxes 20-22 , resulting in a variety of outcomes, including changes in atmospheric greenhouse gas levels 23-25. Therefore, the relationship between LST and LUC change should be investigated...

“…Thus, this study revealed that during the early 2000s, the rate of change of areal averaged temperature over entire urban centers was greater than the 1990s, with the mean, minimum, and maximum increased by 0.7, 1.3, and 0.3 o C, respectively. In East India, Partha et al (2019) documented that an increase in areal-averaged temperatures was associated with LULC changes of urbanization, and with spatio-temporal variation, up to half of the warming due to LULC change in urban centers. Similarly, over four urban centers in Southwest Ethiopia, LULCC could possibly be attributed to the areal-averaged observed minimum, maximum, and mean temperature change with the order of 0.32, 0.41, and 0.32 o C/decade, respectively (Tables 3, 6; Figure 7; Supplementary Figures 2-4).…”

Long-term urban land use land cover change (LULCC) dynamics and climate change trends in Southwest Ethiopia's four urban centers were examined for 60 years. Remote sensing, aerial photos, and Landsat, temperature, and rainfall data were analyzed from a climate change perspective over the Jimma, Bedelle, Bonga, and Sokorru urban centers of southwest Ethiopia from 1953 to 2018. Based on geospatial analysis and maximum likelihood supervised image classification techniques to classify LULCC categories, the Mann-Kendall test was applied to perform trend analyses on temperature and rainfall. The LULCC analysis revealed that built-up areas over the urban centers had shown an increasing trend, with the highest increment by 2,360 hectares over Jimma, while vegetation, wetland, and cropland declined due to conversion of plain lands to built-up areas and other similar zones. The pronounced decline of vegetation coverage was 1,427, 185,116, and 32 hectares in Jimma, Bedelle, Bonga, and Sokorru, respectively. Mann-Kendall test results showed a significant sign of intra-seasonal and inter-annual variability of rainfall while the summer and annual rainfall patterns remained less variable compared to other seasons. This study's findings revealed that when the mean between the two climatic normals of 1953–86 is compared with 1987–2018, the temperature has significantly increased in the latter three decades. The rapid expansion of built-up areas coupled with a sharp decline of green space or vegetation and agricultural/croplands could lead to gradual changes in LULCC classes, which have contributed to the changing of the local climate, especially the surface temperature and rainfall over the urban centers of southwest Ethiopia. Therefore, we recommend that the local urban administrations emphasize sustainable urban development by integrating urban planning policies with land use to protect the environment by adopting local municipal adaptation and national climate change strategies. Restoration of the local environment and creation of climate-smart cities could be critical to the resilience of urban dwellers and ecosystems to the changing climate by enhancing grass-root climate services. To that end, we recommend further advanced research to understand how urban LULC-related changes and other factors contribute to local and regional climates, as urban areas of Southwest Ethiopia are undergoing a rapid transformation of their rural surroundings.

Global warming will have an impact on nature in many ways, including rising sea levels and an increasing spread of infectious diseases. Land surface temperature is one of the many indicators that can be used to measure climate change on both a local and global scale. This study aims to analyze the change in land surface temperatures on New Guinea Island using a cubic spline method, autoregressive model, and multivariate regression. New Guinea Island was divided into 5 regions each consisting of 9 subregions. The data of each subregion was obtained from the National Aeronautics and Space Administration moderate resolution imaging spectroradiometer database from 2000 to 2019. The average change in temperature was +0.012°C per decade. However, the changes differed by region; significantly decreasing in the northwest at -0.107°C per decade (95% CI: -0.207, -0.007), significantly increasing in the south at 0.201°C per decade (95% CI: 0.069, 0.333), and remaining stable in the centralnorth, southeast and northeast.
