Climate change means a change in climate due to an alteration of the global atmosphere that is directly or indirectly attributable to human action and which is added to the natural climatic variability observed in comparable periods of time.

Climate change is caused by various human activities that favor the concentration of greenhouse gases in the atmosphere. There are 4 gases responsible for an increase in the greenhouse effect:
carbon dioxide
methane
nitric oxide
fluorinated gases

The increased concentration of greenhouse gases in the atmosphere leads to an increase in the global average temperature, which in turn triggers a number of other consequences. Climate change above all causes the alteration of entire ecosystems, threatening the survival of plant and animal species. Furthermore, climate change leads to a greater intensity and frequency of extreme weather events: increasingly devastating hurricanes and typhoons, concentrated precipitations in a short time that lead to floods and landslides, prolonged periods of drought and so on.
