Abstract

Understanding future temperature patterns is central to global climate research and national adaptation planning. This study examines projected global maximum temperatures for the late twenty-first century 2081-2100, focusing on the months of June and December, two periods representing opposite seasons across hemispheres. Using gridded climate projections from the WorldClim CMIP6 dataset, the analysis applies geographic information system (GIS) techniques within QGIS to visualise and interpret spatial differences in projected warming. The dataset was derived from the SSP5-8.5 scenario, a high-emissions pathway associated with strong warming, using the ACCESS-CM2 global climate model at a spatial resolution of 10 minutes. The five maps constructed from the GeoTIFF files reveal distinct seasonal patterns, with June showing extreme heat across the Northern Hemisphere especially Africa, Asia, and parts of North America while December displays widespread warming in the Southern Hemisphere and persistent heat in the tropics. The study provides a detailed continental comparison, emphasising regional variations in both magnitude and distribution of heat. Africa emerges as the region of most persistent high temperatures across seasons. A special focus is placed on Ghana, which is located in one of the global hotspots of projected warming. Projections suggest Ghana may experience maximum temperatures exceeding 32°C in both months, with some areas approaching or surpassing 41°C, posing significant risks for agriculture, water resources, energy systems, and public health. This study underscores the importance of spatial climate analysis and provides a foundation for climate resilience planning in vulnerable regions such as Ghana.

Simulation of flooding in Keta municipal district

Image
https://doi.org/10.13140/RG.2.2.26871.89762 The maps above illustrate the spatial extent of simulated flooding in the Keta, Abutiakope, Dzelukope, Tegbi, and Woe areas along the coast of the Volta Region, Ghana. The simulation employs a raster-based modelling technique to visualise progressive sea-level rise scenarios at 1 m, 2 m, and 3 m elevations above current sea level. This approach provides a visual representation of the potential impacts of coastal inundation due to climate-induced sea-level rise (SLR). Analysis of the Maps Map 1 serves as the baseline, showing the existing land cover and settlement pattern without sea-level rise. It highlights the dense coastal settlements and infrastructure in low-lying zones, which are inherently vulnerable to inundation. Map 2 (Sea Level +1 m) demonstrates the initial stage of flooding, where a 1 m rise leads to noticeable encroachment of seawater inland, particularly around the lagoonal systems and coastal fringes. The inundation is concent...
