Global Warming

Global warming refers to an average increase in the Earth's temperature, 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 impacts on plants, wildlife and humans. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities. Coal-burning power and Automobiles are the largest source for pollution. There are several distinct causes of global warming. The first cause is the Greenhouse gases. Scientists are sure about the greenhouse effect; they know that the gases make the Earth warmer by trapping energy in the atmosphere. Another cause is Carbon Dioxide from transportation. Cars, Airplanes and ships Emit CO2 which pollutes the ozone atmosphere. In addition, the increase of global temperature affects on the Sea levels that it rises up. Furthermore, melting ice affects on the amount of the sea.
