According to the UN's Intergovernmental Panel of Climate Change (IPCC), the earth's climate is already changing. The objective of the paper is to analyze how the average yearly sea temperature has evolved at two different geographical spots along the coast of Norway during the period 1936-2003. The statistical analysis is related to the concept and properties of stationary time series. Augmented Dickey-Fuller and non parametric Phillips-Perron tests are applied in the uncovering of the data generation process behind the sea temperature.
