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

Most scientists agree that humans are the main cause of our current global warming movement. We can see by this small bit of information, that we too are contributing to the massive storms that cause much havoc in our

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).

9 of the 10 hottest years ever recorded by NASA occurred in the 2000’s. (“Global”) Global warming, or climate change, is caused when Carbon dioxide, greenhouse gasses and other air pollutants collect in the atmosphere and absorb the solar radiation and sunlight that have already bounced off earth’s surface. This radiation should normally escape into space, but the gasses and pollutants don’t allow it to escape the atmosphere. The pollutants trap the heat causing the planet’s temperature to rise.

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.

B. Thesis: The causes of global warming and climate change are because of increased emissions of greenhouse gases, and the effects of this are rising temperatures and more severe natural disasters. II. Body A. Counter Claim: Most scientist and people believe that humans are the cause of global warming because of the emissions that they put into the air, but there is a small percentage of people who think that global warming is not caused by emissions at all.

Global warming is all about adverse climate change caused by the trapping of greenhouse gases in the earth's atmosphere that affects biodiversity and poses a serious health hazard. Scientists have found strong evidence that human activities have caused most of the warming since the mid-1900 (“global warming”). Humans are responsible for

Global warming and climate change is a polarizing and controversial issue that many people have strong opinions about. There is a strong debate in our society about the threat level posed by global warming and climate change. In reality, global warming and climate change is a real and valid threat to society because of higher temperatures, changing landscapes and wildlife habitat, rising seas, economic impact, increased risk of storms, droughts, and floods, and much more! The human population are at the most critical moment in history; because Earth is at its worst condition. (ever)

According to, (http://www.nytimes.com/ by Justin Gills), “As of October 2015, the Earth had warmed by about 1.7 degrees Fahrenheit since the year 1880, when it is recorded at a global scale”. The number seems to be low, but as an average over the surface of an entire planet, it is actually high. This explains why much of the world’s land ice at the North pole is starting to melt and the oceans are rising at an accelerating pace. The future generations are indeed in a big trouble if this phenomenon is to happen in a long run. In a longer term, if the emission of greenhouse gases are to be worsen, the risks are profound that Scientists fear climate effects so severe that could cause to extinction of plants and animals, and melt the polar ice caps, causing the seas to rise high enough to flood most of the world’s coastal

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

Humans today pollute the air all the time by driving cars, using electricity, flying on planes, and from factories. In the last ten years alone, CO2 emissions have risen 42%. Carbon Dioxide is a big problem because it traps heat into the Earth’s atmosphere (“Climate Change Indicators”). It all goes back to the greenhouse effect. The

Arguably the most significant thing humans have done to cause climate change is the drastic increase in CO2. As a result of human activities, carbon dioxide, methane, nitrous oxide, and the halocarbons (a group of gases containing fluorine, chlorine, and bromine) build up in the atmosphere over time, as well as the natural sources of CO2, like vegetation. The concentration ofCO2 has went from 280 to more than 380 parts per million in just two hundred years. Still currently rising, the burning of fossil fuels by humans will continue to cause global warming and climate

Global warming also referred to as climate change is the gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants in the air today. There are two causes of global warming, human influences and also natural causes. Global warming is increasing day by day because of all the natural causes going on. A greenhouse is a glass building that contains plants in it that needed to be protected from cold weather. These greenhouses attract heat from many things like the
