Introduction to Global warming
Global warming refers to the increase of average world temperatures, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impact on plants, wild life and humans. Greenhouse gases keep our planet warm. They exist naturally in the atmosphere, heating it by trapping energy that has originally come from the Sun. This process is called the greenhouse effect. The greenhouse effect is important. Without the greenhouse effect, the Earth would not be warm enough for humans to live and the Earth would be as cold as the surface of the Moon, about -18°C. But if the greenhouse effect becomes stronger, it will make the Earth warmer than usual. Even a little extra warming may cause problems for mankind, plants, and animals. End state all living things will be affected.
This adjustment in the global climate would have catastrophic results, including drought, coastal flooding and increase in species extinction. And, scientists have discovered a hole in the ozone layer. The ozone layer is the only protection for life on Earth against deadly ultraviolet radiation from the sun. Once the ozone layer is completely destroyed, all life on earth will cease to exist, killed by deadly radiation. The following listed are some of the catastrophe that have occurred due to global warming.
Problems faced by the world today
Droughts – The United States suffered from heat wave and drought in 1988, its worst for 50 years. It was not proven that it was the result of greenhouse effect, but it is something that we could expect in the future if the problem is not solved by then.
Floods - sea levels are already rising at a rate of 1 to 2mm each year due to the melting of the polar ice caps. The predicted rise by 2050 is between 20 and 50cm. This will lead to increased flooding in coastal areas and settlement that live near rivers such as Bangladesh and the Nile Delta,...
