Global Warming: The Science And The Controversy

587 Words3 Pages

Did you know that every day 38.2 billion tons of carbon dioxide is released into the earth’s atmosphere and the United States is the second biggest polluter in the world (Carbon Dioxide Emissions Rise to 2.4 Million Pounds per Second)? Global warming is the heating up of the earth’s average temperature causing the climate to be warmer too. EPA stands for the Environmental Protection Agency, who preserves the environment. EPA believes that the temperatures will continue to increase. Global warming is a very controversial topic some people believe that it is human’s fault and others believe that it is caused naturally (Global Warming: The Science and the Controversy). Humans are speeding up the process of global warming since it would have happened …show more content…

Power plants create electricity for people, but they cause forty percent of carbon dioxide that is discharged from the United States (Global Warming: The Science and the Controversy). Power Plant's work by turning water into steam, and since steam particles are further apart from each other than water it causes the turbine generators to move which creates power. Once the steam has been used to create power it has to go somewhere and so the power plant releases a cloud of steam that contains carbon dioxide in it. Automobiles burn gas and then the exhaust lets out carbon dioxide. Automobiles cause thirty three percent of carbon dioxide emissions. Airplanes cause three and a half percent of global warming. Deforestation is the clearing of trees by a forest fire or by the cutting of the trees. Deforestation is twenty five percent of the global carbon dioxide. One thing that power plants, automobiles, airplanes, and deforestation all have in common is carbon dioxide. Carbon dioxide is a greenhouse gas, meaning it cannot escape the earth's atmosphere and the more that humans use it the warmer the earth will get (Global Warming: The Science and the Controversy). Some people believe that global warming is caused soli by people because they release a profusion amount of carbon dioxide into the

Why Global Warming Skeptics Are Wrong

390 Words | 2 Pages

Although global warming is a big issue, it has not received the attention it deserves. Despite the recent attention drawn to Antarctica, global warming has not raised as much concern as it should. Members in society don’t believe in global warming and can’t see the negative effects resulting from it. William D. Nordhaus, author of the journal Why the Global Warming Skeptics Are Wrong, addressed these arguments against the claims of global warming and provided support as to why global warming is in fact an issue. Although some may not see, temperature trends clearly show the drastic increase in temperature over recent years (Nordhaus 2012).

“In the United States, the burning of fossil fuels to make electricity is the largest source of heat-trapping pollution, producing about two billion tons of CO2 every year. Coal-burning power plants are by far the biggest polluters. The country’s second-largest source of carbon pollution is the transportation sector, which generates about 1.7 billion tons of CO2 emissions a year.”

When these greenhouse gases are emitted into the atmosphere, it can thin this layer and cause the Sun’s ultraviolet light to become stronger and warmer. Therefore heating the Earth. The burning of coal releases carbon into the air that would otherwise be compact under the ground. Coal is combustion-able fossil fuel because it was formed from the remains of vegetation that grew as long as 400 million years ago. It is made up of minerals, carbon and water.

In 2015, greenhouse gas emissions from transportation accounted for 27 percent of total U.S.A. greenhouse gas emissions, making it the second largest contributor of U.S. greenhouse gas emissions (The United States Environmental Protection Agency, 2017). Emissions are the byproducts of engine combustion and the evaporation of motor vehicle fuel. These emissions are released into the air by vehicles as long as they are driving on the road. These emissions are one of the causes of global warming. The greenhouse gases trap the heat into the earth’s atmosphere leading to a rise in temperature.

Burning fossil fuels is one of the main culprits that causes climate change because it releases gases into the atmosphere that trap in heat and create the greenhouse effect. According to Klaus S. Lackner, the director of the Center for Negative Carbon Emissions and a professor in School of Sustainable Engineering at Arizona State University,”Dumping carbon dioxide and other greenhouses gases into the air raises their concentrations in the atmosphere and causes gradual warming.” This gradual warming is causing many horrific effects

Industries generate greenhouse gases during their production process. The emissions from the industries can be divided into direct emissions and indirect emissions. Direct emissions are those which are cause during the production process and indirect emissions are those which are caused by the burning of fossil fuel to generate electricity. These emissions together increase the amount of greenhouse gases in the atmosphere thereby increasing global warming.

Climate Change And Synthesis Essay

Human activities contribute to climate change by causing changes in Earth`s atmosphere in the amounts of greenhouse gases. Since the start of the industrial era (about 1750) the overall effect of human activities on climate has been a warming influence. The United States is the second biggest contributor of CO2 in our environment, however it is home to only 4.4 percent of the total population. In the event that everybody on the planet lived the way individuals do in the U.S., it would take four Earths to give enough assets to everybody. In many ways over time the effect that humans have on the climate is very bad and very dangerous.

With deforestation being one of these roles because when we chop down these trees and plants of where animals habitats our it also releases a lot of carbon dioxide into the air. And if you didn’t know forests are major carbon storage centers, when deforestation happens all the carbon dioxide that is stored in these forests; is released back into the atmosphere. Deforestation not only contributes to changes in the climate, it also causes localized changes in the weather. Trees transpire, or release water into the atmosphere, during photosynthesis. This water replenishes clouds and maintains rainfall.
