In his article Madrigal (2008) says that 60% of the changes in the West's water cycle are linked to the atmospheric greenhouse gases. He describes a research conducted which found that the increases in winter air temperature reduce the amount of snow which falls in the mountains. In return, the snow packs that acted as water storage provide less water as they melt in the spring. Furthermore, human activity can lead to the global warming too. Burning of fossil fuels are blamed for the melting of glaciers and leaving less drinkable water and less water for crop irrigation.
Population growth requires more fresh water for the basic needs of food production.
