Ethiopian summer temperature from the global circulation model output data and its outlooks

Background: Agriculture is the most susceptible sector to climate change related hazards in Ethiopia. Any minor change in temperature from the normal conditions imposes a severe challenge on the agricultural dependent people of Ethiopia. This research work, entitled ‘Ethiopian Summer Temperature from the Global Circulation Model Output Data and its Outlooks’ has been conducted to fill such knowledge gaps of the target population. The objective of the research was to analyze summer temperature from the global circulation model output data and its outlooks with the change of global climate. To attain this specific objective, global circulation model output data were used. These data were analyzed by using Xcon, Matlab and Grid Analysis and Display System computer software programs. Results: The results revealed that the mean temperature has shown a general increasing trend (0.548 °C) since 1971–2010. The best performed models having similar trends to the historical observed temperature data analysis predicted that the future summer mean temperature has been predicted to increase by 0.59 °C (model bccr) and 0.743 °C (model cccma) from 2015 to 2054. Conclusion: It is therefore recommended that the legislative bodies and development planners should design strategies and plans by taking into account impacts of increasing temperature on rural livelihoods. Moreover, adverse impacts of climate change and adaptation strategies should be a crosscutting issue.
