La climatologie est morte!; vive la climatologie!; reflexiones sobre el cambio climático

Abstract

This paper wants to emphasize upon the need of an agreed definition of climate, which furtherly can be used to define the climatic change, an expression which is based on the previous concept of climate. Different definitions have been compiled, beginnig with the classic greek one, where climate denotes a high natural variability, which should also correspond to the derivative concept of climatic change. If the natural variability of climate is not clear, climatic change will suffer the same disease.
