Abstract : This research thesis investigates the impact of climate change on the Arabian Peninsula and Saudi Arabia, particularly the changes in future temperature and extremes in the form of heat waves, droughts, and heavy rainfall. The study uses state-of-the-art regional climate model (RegCM4) simulations to compute future changes for two time slices in the 21st century which are 2036-2065 and 2071-2100 with respect to the reference period 1976-2005. Results show that the central parts of the Arabian Peninsula are likely to get hotter in the future, with projected temperature changes ranging from 1.0-1.5°C under RCP4.5, and 2.0-2.5°C under the RCP8.5 scenario in the mid-century to 4-4.5°C under RCP4.5 and about 4.5-5.5°C under RCP8.5 by the end of the century. The study also examines climate indices for selected cities in Saudi Arabia and finds that warm days and warm nights are expected to increase more than 50% over most parts of the Arabian Peninsula, while the number of cold days and cold nights decrease. Additionally, the study finds that the annual precipitation cycle is expected to change, with an increase in precipitation during the dry season and a decrease during the wet season. The projections for precipitation extreme indices are not consistent among the three global climate models used in the study. Overall, the study highlights the need for careful interpretation of precipitation projections for policy purposes as well as for climate change impact and adaptation related studies. In conclusion, the study provides valuable insights into the potential impacts of climate change on the Arabian Peninsula and Saudi Arabia. The findings highlight the need for urgent action to mitigate the effects of climate change and to implement effective adaptation strategies to minimize the risks to human life and infrastructure in the region.
