Due to the industrialization, transportation and job opportunities excess and adequacy of education and health services, the majority ofthe population of the Marmara Region is located in the Catalca-Kocaeli peninsula.But in recent years, population growth and urbanization have warming effect onclimate in the research area.The main objective of this study is to examine the trend analysis of annual mean temperature from 1970 to 2011. Trend becomes the most commonly used technique to detect temperature variability in regional and local basis. In this study Mann-Kendall Rank Correlation Test was applied to annual mean temperature data fromstations located in Catalca-Kocaeli Peninsula to determine the existence and significance of trends, and the years in which changes in the trends started. In order to discuss the trends of annual mean temperature, the annual Mann-Kendallstatistics of temperature are illustrated in graphics with MATLAB software.
