Global Warming

Introduction

"We must no longer think of human progress as a matter of imposing 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.
