An important issue affecting the world today is climate change due to the increase in the amount of greenhouse gases that is released into the atmosphere. Greenhouse gases are gases that accumulate in the atmosphere due to human activity and the earth's natural biological and chemical processes. The four major greenhouse gases are carbon dioxide , methane, nitrous oxide, and fluorinated gases (U.S. Environmental Protection Agency, 2011). The main contributing factor to climate change is the abundance of carbon dioxide in the atmosphere. Due to the burning of fossil fuels, solid waste, trees, and other chemical reactions carbon dioxide is absorbed into the atmosphere enhancing the greenhouse effect.…
Greenhouse Gases: Carbon dioxide (CO2) is a greenhouse gas in the atmosphere that may raise average temperatures on Earth. The burning of fossil fuels could be responsible for the increased levels of carbon dioxide. If current trends continue, future concentrations of atmospheric carbon dioxide in parts per million (ppm) could reach the levels shown in the accompanying table. The CO2 concentration in the year 2000 was greater than it had been at any time in the previous 160,000 years.…
Glaciers are melting, sea levels are rising, forests are drying and wildlife is suffering, these are all results of the apparent rise in global temperatures and it has become more obvious that humans over centuries are releasing harmful heat-trapping gases into the atmosphere known as greenhouse gases. The greenhouse effect causes the increase in global temperature as the gases which are released into the atmosphere allow light to be entered, but prevents heat from escaping.…
Greenhouse gases are keeping the Earth’s surface and low layers of the atmosphere warmer and the upper layers are to be colder because of the gases. 10-20% of the Earth’s natural greenhouse effect is due to carbon dioxide, methane and other gases like nitrogen and oxygen for example.…
Since the time of the Industrial Revolution, human activities have polluted the air with large amounts of greenhouses gasses. These gasses are thick covering the Earth in the atmosphere creating and trapping more heat on Earth’s surface; this is known as the greenhouse effect. While the greenhouse effect is needed to support life on Earth, a continuous buildup of these gasses becomes harmful. Greenhouses gasses come from burning fossil fuels, deforestation, industrial processes, and some agriculture practices. When the carbon dioxide is released by these activities it is trapped in the lower part of the troposphere heating the surface of the Earth thus creating global warming. The most significant greenhouse gas is carbon dioxide; it can cause the most substantial increase in temperature.…
Several greenhouse gases occur naturally in the atmosphere, while others result from human activities that add to the levels of most of these naturally occurring gases. Naturally occurring greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone.[ Carbon dioxide is released into the atmosphere when solid waste, fossil fuels such as oil, natural gas, and coal, and wood and wood products…
Greenhouse gases are responsible for trapping heat in our atmosphere. The increase in greenhouse gasses caused by human activity are a primary cause of global warming.…
Global warming causes a gradual increase in the average temperature of the Earth’s atmosphere and its ocean. Likewise, the increase of carbon dioxide and other greenhouse gases are believed to be the major concern and a source of permanent climate change in the past 50 years. Let’s look at the cause; there is an obstruction of gases around…
Global warming refers to an increase in global temperatures that happens at a gradual scale and has been attributed to the greenhouse gasses produced by industries through the release of chlorofluorocarbons, carbon dioxide and many other air pollutants (Haldar). The gasses trap heat energy from the sun causing the gradual increase in temperatures. Global warming has had negative impacts on many ecosystems around the world among them droughts, unpredictable weather patterns, sea level rises and retreating of the major ice sheets due to melting. Global warming has had an effect even on the arctic tundra. Most researchers agree that human activity is the most responsible for causing global warming.…
2. Carbon dioxide is considered the main greenhouse gas because its widely abundant and contributes the most to the greenhouse effect. Even though it can be less potent, it is six times more prominent than other gases. An increase in water vapor can cause a positive feedback effect by creating a loop of increased water into the air by an increase of evaporation through an increase of temperature. A negative feedback effect loop sees an increase in clouds that shade or cool the earth. This could slow the warming by reflecting back more solar radiation into space.…
Greenhouse gases are natural occurring gases that hold in some of the heat energy that comes from the sun and bounce off of the earths’ surface; it’s not that these gases are bad in nature, we actually depend on them to keep the climate of our earth at a sustainable temperature, with that being said though, they are only positive for our atmosphere in moderation. In nature the gases such as CO2, Nitrous Oxide and…
Every year, almost 7 billion tons of carbon dioxide is released into the atmosphere by human activity (“How do we contribute individually to global warming.” Global Warming: 2006. Web.12 Oct. 2011). That is the equivalent of 107,700,000 jet airplanes being in the air at once! This harrowing figure is the main cause of global warming, and has been increasing for the last 50 years. Global warming is caused by the increase of greenhouse gases, carbon dioxide and methane primarily, in the earth 's upper atmosphere directly caused by human burning of fossil fuels, industrial, farming, and deforestation activities. Global warming is defined as an increase in the average temperature of the earth 's atmosphere (especially a sustained increase that causes climatic changes). Many people believe in these statements, but there are many people around the world that refuse to believe that human contributions are the main cause of global warming, saying that the increase is part of the natural climatic change of earth.…
Since the beginning of Industrial Revolution, concentrations of carbon dioxide, methane, and nitrous oxide have all risen dramatically because of human activities. Fossil fuel combustion, land-use change, increasingly intensive agriculture, and an expanding global human population are the primary causes for these increases. Other greenhouse gases found in our planet's atmosphere include water vapor and ozone. Carbon dioxide is released into the atmosphere by the burning of solid waste, wood and wood products, and fossil fuels (oil, natural gas, and coal).…

Pollution is the main cause of global warming. It is defined as: the release of chemicals and particulates into the atmosphere. Some examples are Carbon monoxide, Sulfur dioxide, Chlorofluorocarbon, and Nitrogen oxide produced by big industries and car emissions. When there is an overabundance of pollution in the air the sun’s rays get trapped on earth because of something called the Ozone layer. The Ozone layer is the part of the Earth’s atmosphere which contains relatively high concentrations of Ozone (O3). This causes the ozone to be…
