Global Warming - Paper 15

Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. The earth is getting warmer. The changes are small, so far, but they are expected to grow and speed up. Within the next fifty to one hundred years, the earth may be hotter than it has been in the past million years. As oceans warm and glaciers melt, land and cities along coasts may be flooded. Heat and drought may cause forests to die and food crops to fail. Global warming will affect weather everywhere, plants and animals everywhere, people everywhere; humans are warming the earth's atmosphere by burning fuels, cutting down forest, and by taking part in other activities that release certain heat trapping gases into the air.

One major cause of global warming is the use of fossil fuels. Fossil fuels like coal, oil, and natural gas that were formed from the remains of plant material deposited during the earth's carboniferous period. We have known for only a few thousand years that coal, oil, and natural gas can be burned to provide energy. It was not until the mid-1800s, however, that we began to burn very large quantities of these fossil fuels. The worldwide consumption of fossil fuel has increased dramaticall Today, global warming is an undeniable fact, which proves that our planet and its climate are in trouble. Global warming affects all areas of our life: politics, economics and a social sphere. The study of global warming involves many sciences in order to examine the causes of global warming and try to find possible solutions to reduce the impact of our civilization on the planet. An interdisciplinary research in this field is important, because global warming is caused by many factors and has an impact on different spheres of our life. For instance, climate science is aimed to investigate the changes caused by global warming. Geology examines the impact of human activities (drilling) on climate. Economic science helps to understand economic...
