Global Warming
...ourselves on the natural environment. The world--the climate and all living things-- is a closed system; what we do has consequences that eventually will come back to affect us." - UNEP
Climate change is one of the most ardently debated topics on globe at present. The frequency and intensity of extreme climactic change such as changing composition of earth atmosphere, unprecedented melting of glaciers and rise in the level of sea, increasing numbers of hurricanes and other anomalous events have forced scientists, researchers, and policymakers to believe that the earth is going through major climatic change. Experts argue that the changes in the global temperature are becoming excessive and wayward enough that something other than natural causes is driving them. Many researchers assert that human activities such as deforestation and the emission of greenhouse gases such as carbon dioxide and chlorofluorocarbons (CFCs) into the atmosphere are to blame for the present and predictably for the future changes in the earth's climate.
Experts believe that the condition of the atmosphere has worsened to such a level that the implementation of suggested protocols would only lower insignificant amount of green house gases from the atmosphere.
Greenhouse Effect
The greenhouse effect is a natural component of the Earth's geophysical balance necessary for the existence of the biological sphere of Earth. It is the rise in temperature that the Earth experiences because of gases like water vapor, carbon dioxide, nitrous oxide, methane and others in the atmosphere that traps energy from the sun. Because of how they warm up the Earth, these gases are referred to as greenhouse gases. Without these gases, heat would escape back into space and Earth's average temperature would be about 60ºF colder. In other words, without a natural greenhouse effect, the temperature of the...
