Global warming is the rise in the average temperature of the Earth's atmosphere. Recent decades have seen very high average global surface temperature. This global warming causes the climate to change. Climate change is predicted to have overwhelming effects on the environment and on socioeconomic and related sectors, including water resources, agriculture, human health and coastal zones. The global temperatures are likely to rise about 6 0 C, if not checked. The cause of global warming is mostly by human interferences like deforestation and increase in the emission of green house gases. CO 2 is a major contributor to the green house effect and global warming. 91% of CO 2 emission enters the atmosphere by burning of fossil fuels (for eg. natural gas, coal, oil and gasoline), gas flaring and cement production. The poles are affected most by the elevated earth's temperature resulting the glaciers, polar ice to melt and sea level to rise. Studies show that the summers in the arctic region may be ice-free by 2040. The climate change is a great threat to human life causing the intensity and frequency of floods, storms, cyclones, droughts to rise. This temperature enhancement will increase the rate of extinction for many habitats and species and it would become difficult for life to sustain on earth. Developing new energy polices and initiatives can help save the planet and health of our earth's inhabitants today.
