Climate change is caused by the greenhouse effect, where certain gases, known as greenhouse gases (GHG) trapped radiation from the sun. Scientists have known about the greenhouse effect since 1824 when J. Fourier calculated that the Earth would be much colder if it had no atmosphere. This greenhouse effect is what keeps the Earth's climate livable. Without it the Earth's surface should be an average of 60°F colder, it the Earth's surface would be an average of 60°F colder.
Some GHG such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone, occur naturally, while other results from human activities. Very powerful GHG that are not naturally occurring include hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. Human activities have an upset natural balance of GHG which is resulting in a rapid change to the global temperature. This will affect rainfall, to the global temperature. This will affect rainfall, temperatures, extremist of weather and sea level rise.

Water on the earth is being recycled continuously in a process known as hydro logic cycle. The hydro logic cycle begins with the evaporation of water from the surface of the ocean. As moist air is lifted, it cools and water vapour condenses to from clouds.Moisture is transported around the globe until it returns to the surface as precipitation. Once the water reaches the ground, one of two process may occur; (i) some of the water may evaporate. back into the atmosphere or (ii) the water may penetrate the surfaces and become grounding water. Groundwater either seeps its way into the oceans, rivers and streams or is released back into the atmosphere through transpiration of plants. Groundwater is the major source of water for many cities. But as the population increases and the need for water also increases , the ground water level in some areas is getting dangerously low. Added to this problem is an increasing amount of population that seeps into groundwater. In the future with growing anthropocentric activities and more toxic wastes the hydro logic cycle we depend on become dangerously imbalanced.
