Climate Change: Global Warming Introduction The sea is slowly rising, the plants are gradually dying, and the planet’s ecosystem is steadily failing. Global warming is a world-wide issue. The world is slowly increasing temperature, and life is greatly affected by this change. Although a slight change of temperature does not affect humans directly, other life on earth such as micro organisms are affected and eventually, a whole food web may collapse. Cities may be covered in water and millions could be homeless. Many people do not realise this and although they may not notice, they are contributing to the death of our planet. In this investigation, I will study further into global warming and what effect it will have on us. The Cause of Global Warming There is no single cause to global warming. Many factors put together cause the warming of the earth. However, there is a major contributor to global warming, carbon dioxide. Carbon dioxide is released from a wide range of causes, natural or by humans. The earth is like a large spherical greenhouse. The sun warms up our atmosphere and it absorbs the heat and radiates the energy to the surface of the earth and this is how earth can maintain a steady temperature throughout day and night. The atmosphere is composed of numerous gases. They consist of mainly, water vapour, carbon dioxide, methane and ozone. However there are more gases which are not as common as the others, such as nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and chlorofluorocarbons. Together, these gases cause the greenhouse effect. The Greenhouse Effect When the sun’s rays reflects from earth, the greenhouse gases in the atmosphere absorb some of the energy and radiates it back to earth therefore causing the surface of earth to increase in temperature. The modern ages and our ways of pollution have brought many more
