According with the Intergovernmental Panel of Climate Change, the ongoing Climate Change has been caused by our own Technological Civilization. Its high rate of progress is due to the increase in the concentration of CO2, in the stratosphere, as a result of the large-scale use of fossil fuels, as well as the misuse of soils and massive deforestation. This work describes the evolution of Climate Change both globally and locally. In order to study the progress of this phenomenon in Panama, temporary minimum temperature series (30 years of data) were studied, corresponding to four meteorological stations located in the Azuero Peninsula. The stations whose data were analyzed are those of Pedasi, Tonosi, Chepo and Divisa. The analysis of the temporary temperature series of those stations shows a tendency of sustained increase of this meteorological variable.
