1. The phenomenon whereby the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface.
2. A similar retention of solar radiation, as by another planet or in a solar panel.

heating of the atmosphere resulting from the absorption by certain gases of solar energy that has been captured and reradiated by the earth's surface.

Greenhous gas
Carbon dioxide is the greenhouse gas of most immediate concern, because it is the most concentrated in the atmosphere and because it can persist for over 100 years in the atmosphere once emitted. On a per molecule basis, other gases can trap even more heat than carbon dioxide. The overall measure of a gas’s ability to contribute to global warming is called the Global Warming Potential (GWP) which measures the combination of the gas’s ability to trap solar radiation as heat and the length of time it persists in the atmosphere. The GWP of a gas is calculated relative to carbon dioxide's GWP. As the right hand column of the table shows, most other greenhouse gases have far greater GWPs than carbon dioxide. Human combustion of fossil fuels for energy is the primary source of atmospheric greenhouse gases. More recently, the production of the extremely high-GWP man-made gases has been growing at a much faster rate than carbon dioxide emissions. To understand how fossil fuel

Sustainability: Carbon Dioxide Emission Essay

back into space; some atmospheric gases (carbon dioxide, and other gases) Hold some of the escaping energy and retaining heat like the glass barrier of a greenhouse; these gases are therefore known as greenhouse gases; the greenhouse effect is the increase in temperature on earth as certain gases in the atmosphere hold energy. The greenhouse effect is a part of the natural processes; however, burning fossil fuel and deforestation also produce carbon dioxide into the atmosphere and therefore increases…

Carbon Dioxide and Sulfur Dioxide Emissions Essay

World in Danger Humans have been inventing tings throughout history. Recently these inventions needed the burning of fossil fuels to power them. Burning the fuel releases carbon dioxide into the air, warming the Earth’s surface. The global warming is weakening plants and animals all over the Earth. World leaders should sign a binding agreement to lessen the effects of global warming because it may save the world from devastation. Signing a binding agreement may help the environment, but countries…

Environment: Carbon Dioxide and Greenhouse Gas Emissions Essay

global average temperatures would respond uniformly to increases of carbon dioxide and other greenhouse gas emissions. But the NASA study showed global temperatures are more sensitive to changes in aerosols and ozone in the atmosphere. This higher sensitivity could mean a larger and faster temperature response, according to the study. The study's findings could have “a really profound impact” on the amount of greenhouse gas emissions reductions needed for countries to meet an international goal of…

Essay on Greenhouse Effect Killing Our Earth

Greenhouse effect killing our earth!? Since the industrial revolution, humans produce into the atmosphere ， highly endothermic carbon dioxide and other greenhouse gases increased year by year, also increases the greenhouse effect of the atmosphere, has caused a series of serious problems such as global warming, caused countries around the world attention. In addition to carbon dioxide, an important role for the greenhouse effect gases as well as methane, ozone, chlorofluorocarbons and water vapor and the…

Temperature Changes In Artic Glaciers

although some Artic glaciers have lost mass, there is no real evidence that Artic glaciers have diminished faster because of carbon dioxide emissions (Krajick, 2001). Furthermore, a study conducted over the course of 35 years used NASA satelites to track temperature changes in the South Pole and compared the temperature changes to the corresponding carbon dioxide emissions. The…

Taxation: Tax and Greenhouse Gas Emissions Essay

Carbon Tax Rates Carbon taxation options Broadly speaking, the various carbon tax options that have been evaluated or suggested in Australia can be divided into: small carbon levies without revenue recycling, which involve hypothecation of revenue, and no reduction in taxes; and large carbon tax options with revenue recycling. These typically aim at stabilising emissions using a carbon tax with the revenue being handed back with a reduction in INCOME TAXES, PAYROLL TAXES or other indirect…

world’s emission of carbon dioxide. In addition, Americas own approximately 30 percent of the world’s vehicles, drive farther each year than the international average and burn more fuel per mile. Freeman also states that according to the report, GM, the number one U.S. automaker, produced as much carbon dioxide in 2004 as American Electric Power Co., the nation’s largest operator of coal-fired power plants, and all the automakers resisted government restrictions on carbon dioxide emissions because…

CO2 Affecting The Ocean

the effects in the ocean. CO2 is also known as carbon dioxide. PH is the measurement of acidity levels, the scale goes from 1 to 14. CO2 is produced in multiple ways that we use in everyday life, including: transportation, electricity, etc.. CO2 is also known as carbon dioxide, which is a greenhouse gas. The amount of emissions of carbon dioxide has risen. The ocean is becoming more acidic from the carbon dioxide emissions. Due to carbon dioxide emissions, ocean acidification is taking place. The ocean…

Global Warming Research Paper

becoming more serious. This essay will discuss the causes and effects of global warming. One of the main causes of global warming is carbon dioxide emissions. My point is about the way people pollute the environment. All human activities in real life such as using cars, burning fuel result in increasing carbon dioxide emissions. Because carbon dioxide emissions comes from the burning of gasoline in internal-combustion engines of cars and it also comes from the burning of fossil fuel such as oil…
