Global warming is the rising of average temperature of the Earth’s atmosphere due to greenhouse gases. Greenhouse gases are gases that trap heat in the atmosphere. The greenhouse effect consists of gases such as carbon dioxide, methane, nitrous oxide, and water vapor insulating the Earth’s surface and helping it maintain warm temperatures. However since there is so much carbon dioxide filling the air the Earth atmosphere absorbs almost all of the suns emission. When the sun heats the earth the atmosphere is supposed to radiate most of the heat but instead it takes all the warmth and uses it to power the Earth causing a buildup of green house gases. This has been taught to everyone, but is it true or a hoax? Some scientists argue that global warming is nothing to worry about and that it is just a myth. Nevertheless there are other scientists who say the world will enter a vast drought because of the rising temperatures. Global warming affects natural and geographical and historical boundaries. “The rising temperatures cause ice sheets to shrink more and more every year and because of that the sea level rises,” reported CNN. This also makes animals such as the polar bear and penguins become endangered because their habitat is melting. Droughts and heat waves also can be an effect to the rising of global temperatures. New diseases are spread from country to country due to deforestation. Economic situations play a part in this issue because of the coat for power plants and wind turbines. This charge can make the poorest people never be able to escape a life of poverty. The rising sea level could be enough to flood low lying cities such as New York City and Shangia, China.
