In its most common sense, the term climate change is explained as ‘the changes on climate as caused by human activities’ (ERM 2007, p.1). Usually, climate change is reflected in ‘the alteration of the composition of the global atmosphere’ (ERM 2007, p.1). There are several factors that are related to climate change. In a study developed by the Intergovernmental Panel on Climate Change (2007) it is made clear that the relationship between climate and specific events has not fully explored. For this reason, when trying to evaluate climate change it is necessary to refer to appropriate parameters (Intergovernmental Panel on Climate Change 2007, p.718). In any case, evaluating climate changes can be a challenging task since climate conditions are not standardized (Intergovernmental Panel of Climate Change 2007, p.718).
