Temperature Trend Analysis and Investigation on a Case of Variability Climate

Climate change is now evident on a global scale. In some regions, the phenomenon especially amplified, generating different consequences for man and environment. Sicily one of Mediterranean biggest in terms area, where climatic variations produce significant effects. this study, temperature trends monthly time scales are examined frame 1925–2015. The cluster analysis technique (Ward’s method) was used to homogenize series. results show four statistically clusters, confirming presence variability region. non-parametric Mann–Kendall test determine trends. estimator Sen’s slope quantify variation showed A worrying unexpected increase temperatures found during winter period. This scenario presented three highlighting mutation season, attributable changes progress rather than territorial factors. If maintain an increasing monotone character, coming decades there will be, many areas Sicily, constant loss fertile soil agricultural sector advancement phenomena such as drought desertification, which island already predisposed. All have serious socio-economic repercussions. Considering that large part region’s economy based sector, these repercussions be followed by environmental implications negatively affect ecological sustainability
