GLOBAL WARMING AND GREENHOUSE EFFECT

Abstract: Global warming is the alleged worldwide increase in the average atmospheric temperature of Earth’s near-surface air and oceans since the mid 20th century and its projected continuation. The historical perspective increase since the middle of the 20th century has been caused by increasing concentrations of greenhouse gases (heat trapping gases) because they produce the greenhouse effect (i.e. these gases absorb the heat energy and tend to prevent infrared heat radiation from escaping into space from the earth, thus causing the Greenhouse Effect). The principal greenhouse gases are carbondioxide, methane and nitrous oxide. Others are halocarbons, ozone and water vapour. The effect of global warming (both positive and negative) on the environment causes of global warming (natural and anthropogenic) and what is being done by the people, and the governments to stop global warming were also examined. In conclusion, “a more aggressive approach to global warming should be adopted as it is undeniable and urgent ” according to the words of one time 200
