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 ice dome melted, sea levels would rise to very high levels as result the world would have to completely redraw every map of the world. Miami, Florida would be underwater, as well has many other coastal cities around the world. People living in these cities would have to move, and some countries just don’t have enough land to support more people way from the coasts. And that’s not all. This rise in sea level may even cause ocean water to enter groundwater causing water contamination. Another fact to consider the devastating hurricanes that hits American every year causing a lot of Disasters and death. For example, Hurricane Katrina was the deadliest and most destructive Atlantic hurricane of the 2005 Atlantic hurricane season. It was the costliest natural disaster, as well as one of the five deadliest hurricanes, in the history of the United States. Hurricane Isaac was the final tropical cyclone of the 2006 Atlantic hurricane season. Isaac originated in a tropical wave that entered the Atlantic Ocean on September 18.
An associated area of disturbed weather eventually organized sufficiently to be declared a tropical depression on September 27, while located 930 mi (1,500 km) southeast of Bermuda. Hurricane Irene was a large and very destructive tropical cyclone, which affected much of the Caribbean and East Coast of the United States during the 2011 Atlantic hurricane season. Irene is currently ranked as the fifth costliest hurricane in United States history. The effects didn’t stop only at the hurricanes but it effect people around the earth with diseases too for example: 1,272,000 people around the world that died of Malaria between 2002 and 2003, all because of a couple deformed insects carrying the disease, or that “the snows of Kilimanjaro” will have disappeared in 10 years, according to Dr. Lonnie Thompson. Finally, people all around the world wants to live in save healthy world with now diseases and hurricanes. So, there is so much the community of human beings can do to help their planet and get it back to normal. Simply by reducing energy for example – use energy efficient light bulbs, recycle, and take shorter showers. The last main world to consider are save energy to save the world.
