Abstract: The main objective of research was to examine temperature trends and household’s perceptions on temperature characteristic changes. Maximum and minimum temperature data records for 31 years were used in the study. The sources of the data were gridded meteorological satellite data of 250 grid cell points and 400 households from Kolla Temben district. Meteorological data was accessed from the TAMSAT satellite. The data were analyzed in monthly and annual bases to investigate the variability and trends of temperature for the past 31 years. The study revealed that temperature has increased rapidly with more extreme events. Minimum and maximum temperature was increased at 0.0348 and .0848 degree Celsius per year respectively for three decades. The temperature increase pace of the district for past 31 years was much greater than the average global surface temperature speed in the past hundred years (1905-2005, 0.74 degree Celsius). Most of households were found perceiving that temperature has increased more rapidly in the past three decades. The 31-year temperature trend analysis confirms that some areas may face unpredictable and very odd climate feedbacks in the near future. Reversing temperature increases could take hundreds of years as some of the GHG atmospheric life time is very long and; the atmosphere has already absorbed enough GHG to sustain the existing trends for decades. Vulnerable societies should be addressed by evidence based adaptation policy direction as climate is unstoppable. Mitigation through adaptation is the most appropriate way to achieve two goals at a time; adapting the existing changes and fighting for the possible future temperature changes. More area specific researches should scrutinize the possible temperature changes and potential impacts as climate change peril the planet unevenly.
