Global warming may be broadly defined as an increase in temperature of the Earth’s surface including land and water coupled with its atmosphere. Average temperatures around the world have increased by 0.75°C (1.4°F) over the last 100 years but 66 percent increase has witnessed since 1975 . The predominant causal factor presently is accumulation of greenhouse gases in the atmosphere produced by human activities .However, the natural greenhouse effect makes it possible for humans and many other life forms to exist by balancing the Earth’s temperature at a safe level  but, since the Industrial Revolution the greenhouse effect has resulted in increase of Earth’s average temperature by almost 1°C thereby causing global warming .

The predominant cause of Global warming is on account of release of carbon dioxide (CO2), other air pollutants and greenhouse gases into the atmosphere on account of human activities where sunlight is absorbed by them along with solar radiation that have bounced off the earth’s surface. In fact these radiations should have reflected back into space but these pollutants trap the heat resulting into hotter planet. This phenomenon is known as greenhouse effect which causes global warming. A symbolic diagram of global warming is shown in Figure 1.

Global warming is an emerging global issue world over and need to be effectively addressed technologically, economically, socially and politically in an integrated manner with all sincerity and commitment. An approach to reduce generation of green house gases needs to be linked with economic benefits in order to attain sustainability. Adequate research needs to be undertaken world over in respect of all the relevant parameters and should be made public to create awareness.
