Global warming may be defined as the phenomenon of a gradual increase in the mean temperature of earth and ocean. It is a result of the concentration of greenhouse gases and carbon dioxide on the earth's atmosphere. Human action over the past century has speeded the process global warming. The unprecedented scientific and industrial advancement we made over the last century has nature as its casualty. Global warming is a real threat facing earth and its very existence. Global warming effects certain climatic changes affecting the balance of our nature and raising questions about its sustainability. Climatic changes happen as result of natural processes or it can be forced by human action. Naturally occurring gases like carbon dioxide, carbon monoxide, methane, nitrous oxide and ozone show green house properties and cause the warming the earth's temperature but it is a natural process and is controlled. But rapid industrialisation and thoughtless less use of resources released very high levels of the greenhouse gases to the atmosphere. Certain gases like hydrofluorocarbons, perfluorocarbons are released as result of increased industrial activity and combustion of solid waste, .fossil fuels and coal. It has resulted in a phenomenon called greenhouse effect, which results in trapping the sunlight that enters the earth and not allowing them to escape the atmosphere thereby increasing the temperature. This phenomenon will have disastrous effects on the ecological balance and different natural cycles, like the water cycle. It can even result in melting the polar ice cap and flooding the coastal areas of the world and also habitat destruction and thereby extinction of animal and plant species. It is also sure to have a lot of other consequences that can even question the future of earth as the only living planet. It is high time the people initiated some action against the thoughtless and unsustainable development projects. Although time is fast running out there is hope and the situation can be brought under control by reducing the release of such greenhouse gases and rapid re-forrestation. If these measures are initiated immediately and executed properly things could well be brought under control. Creating awareness among people and alerting them against the ill-effects of global warming can help avoid disaster. But, what has to be done immediately is to effect law and restrictions by the governments of the countries, especially the more developed ones, to control the release of these gases.
