Earth in Danger
Nobody can negate that a lot of phenomena has been changed in our world recently while wondering the reason of these changes. One of the main reason for a lot of change in our life is the rapped raise on temperature which is called global warming. Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980 according to Wikipedia. Most scientists agree that Global Warming is real, with a few exceptions. Warming of the climate system is unequivocal, and scientists are more than 90% certain that it is primarily caused by increasing concentrations of greenhouse gases produced by human activities such as the burning of fossil fuels and deforestation These findings are recognized by the national science academies of all major industrialized nations. Now there is main question how did we get these greenhouse effect? ; This is how it works: the sun radiates heat to warm the surface of the Earth. Some of the heat bounces off the surface of the Earth, while the rest is kept inside the Earth’s atmosphere. The Greenhouse Affect happens when certain gases, such as carbon dioxide, prevent the sun’s energy from escaping Earth’s atmosphere, which causes the temperature to rise. And here is the scary fact- the U.S.A. emits more greenhouse gas pollution than South America, Africa, the Middle East, Australia, and Asia combined. As the result of rapped increase of the earth temperature it melts the ice in the polar icecaps. Many people think that this doesn’t seem like it would affect The United States, because the only thing everybody heard that Antarctica slowly shrinking is that the cute waddle polar bears will have no home. But this does in fact have an impact on people all over the world. For example, if Greenland’s...
