Global Warming Global warming is the increase of world’s average temperature‚ mainly in the sector of atmosphere‚ seas and the land on Earth. here are three serious factor‚ namely the crack on the lower part of atmosphere‚ pollution on Earth an so many green houses. The first factor is on the atmosphere. Recent years‚ many researches show that atmosphere has some kind of crack because of the heat from sun’s emission. The layer of atmosphere seems can not take the heat anymore. The crack gets larger

Pollution - Environmental pollution is any discharge of material or energy into water‚ land‚ or air that causes or may cause acute (short-term) or chronic (long-term) detriment to the Earth ’s ecological balance or that lowers the quality of life. Pollutants may cause primary damage‚ with direct identifiable impact on the environment‚ or secondary damage in the form of minor perturbations in the delicate balance of the biological food web that are detectable only over long time periods. Until relatively

expressing concerns about changes in the overall climate of the earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate‚ a problem that is referred to as "global warming." This paper will attempt to explore this very issue‚ its causes‚ dangerous and somehow deadly effects and how we could deal with this global crisis. Global warming has become perhaps the most complicated issue facing world leaders. Warnings from the scientific community are becoming

The most important problem faced by the modern world today is environmental pollution. Unless and until effective measures are adopted to prevent this grave problem‚ it is going to affect life on earth. Man has exploited the natural resources in order to meet the demands of the ever-increasing population and also to meet the requirements of industries. As the demand for basic things like food‚ water‚ clothes and shelter increased; man exploited natural resources like minerals‚ forests‚ water and

Meaning of Global Warning A gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide‚ CFCs‚ and other pollutants. Climate change is any substantial change in Earth’s climate that lasts for an extended period of time. Global warming refers to climate change that causes an increase in the average temperature of the lower atmosphere. Global warming can have many different causes‚ but it is most

Global Warming A common topic known worldwide as controversial and challenging is global warming. Many people do not know the cause and effect between man-made activities‚ practices‚ and behaviors that have contributed significantly to global warming.

1) What is global warming? (History) Definition: Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. Common sense:Glaciers are melting‚ sea levels are rising‚ cloud forests are drying‚ and wildlife is scrambling to keep pace. It’s becoming clear that humans have caused most of the past century’s warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases‚ their levels are higher now than
