Understanding projected changes in climate extremes at local and regional scales is critical for reducing society’svulnerability to such extremes, as it helps to devise informed adaptation strategies and contributes to informed decision-making processes. In this paper, we analyse projected changes in climate extremes across regions in Tanzania usingoutputs of high-resolution regional climate models from the Coordinated Regional Climate Downscaling Experimentprogram (CORDEX-Africa). The indices analysed here are those recommended by the Expert Team on Climate ChangeDetection and Indices (ETCCDI) to characterise climate extremes over different regions. The results revealed thatTanzania would experience an increased number of warm days and nights during the present, mid, and end centuriesunder the RCP4.5 emission scenarios The number of consecutive wet days (CWDs) and consecutive dry days (CDDs) arelikely to increase across regions. Areas along coastal regions would experience increased intensity and frequency ofextreme rainfall events in the present, mid, and end centuries under the RCP4.5 emission scenario. These increases inextreme climate events are likely to pose significant damage to property, destruction of infrastructure, and othersocioeconomic livelihoods for people in many regions of Tanzania. It is therefore recommended that appropriate policiesare put in place to help different sectors and communities at large adapt the impacts of extreme climatic events.

In recent years, extreme climatic events such as heavy rainfall and droughts are common and have contributed to the loss of lives, damage of properties, destruction of the environment and socio-economic livelihood of people predominantly in many developing countries. Characterizing these events to understand their temporal and spatial evolution is of great considerable benefit to different sectors; for instance, energy, agriculture, health and water resource sectors. In this study, we use the outputs of regional climate models to characterize the temporal and spatial evolution of extreme climatic events over Tanzania. Results reveal that all regions across Tanzania are projected to experience a statistically significant increased frequency of extreme climatic events related to temperatures. However, the frequency of extreme climatic events related to rainfall is projected to increase at a non-significant level across most regions. The presented increase in extreme climatic events is likely to pose significant damage to the agriculture sector,
