Sources of Greenhouse Gas Emissions Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.

- What are the sources of carbon dioxide? Carbon Dioxide (or CO2) is created naturally by animals' breathing (respiration) and by the decay of plant and animal matter. These processes are natural sources of carbon dioxide in the atmosphere and account for about 38% of all CO2 emissions (Figure 1).

Main sources of carbon dioxide emissions 42.84 percent of all naturally produced carbon dioxide emissions come from ocean-atmosphere exchange. Other important natural sources include plant and animal respiration (28.56%) as well as soil respiration and decomposition (28.56%). A minor amount is also created by volcanic eruptions (0.03%).7 percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil. The remainder results from the clearing of forests and other land use changes (9%), as well as some industrial processes such as cement manufacturing (4%).

1. the suns rays reach the earths surface without any proble Greenhouse Gases. We noted earlier that water vapor (H2O) and carbon dioxide (CO2) are two of the major greenhouse gases. Both of these molecules are present on Earth naturally, their amounts having evolved to steady levels as a total effect of plant and animal life.There are several other gases that contribute to the greenhouse effect.f all the greenhouse gases, carbon dioxide is present at the highest concentration by far. Based on 1990 concentrations, carbon dioxide is said to be responsible for almost 60% of the total greenhouse effect when efficiency and concentration are considered.

Greenhouse Effect Many greenhouse gases occur naturally in the environment, such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Others such as hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) are created and emitted solely through human activities.

Greenhouse Gas Emissions: Causes & Sources A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere.

Introduction As the shortwave energy (that in the visible and ultraviolet portion of the spectra) heats the surface, longer-wave (infrared) energy (heat) is reradiated to the atmosphere. Greenhouse gases absorb this energy, thereby allowing less heat to escape back to space, and 'trapping' it in the lower atmosphere. Many greenhouse gases occur naturally in the atmosphere, such as carbon dioxide, methane, water vapor, and nitrous oxide, while others are synthetic. Those that are man-made include the chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs) and Perfluorocarbons (PFCs), as well as sulfur hexafluoride (SF6).

Carbon dioxide in Earth's atmosphere Another large natural source of CO2 includes the oceans. Carbon dioxide is also released by the burning of fossil fuels (coal, oil and gas) for power and electricity, and the production of cement. These are anthropogenic or man-made sources of carbon dioxide. Although man-made emissions of CO2 are significant, they are much smaller than natural emissions.

What is a Greenhouse Gas? The presence of four major greenhouse gases, namely water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) in the Earth's atmosphere keeps the average temperature of 15º C (59º F), whereas without the greenhouse effect the average temperature would be a frosty -18º C (0º F). greenhouse gas (often abbreviated as GHG) is a gas that both absorbs and emits radiation in the infrared range, commonly called thermal radiation or heat.

Where Greenhouse Gases Come From In the United States, greenhouse gas emissions come primarily from the burning of fossil fuels in energy use. Carbon Dioxide. Carbon Dioxide is the main greenhouse gas. In 2013, 82% of human-caused greenhouse gas emissions were carbon dioxide emissions, resulting from the burning of fossil fuels, solid waste, trees, wood, and other chemical reactions. Methane and Other Gases.

Greenhouse gas Greenhouse effect schematic showing energy flows between space, the atmosphere, and Earth's surface. Energy influx and emittance are expressed in watts per square meter (W/m2). A greenhouse gas (abbrev. GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.

Agriculture and Livestock Remain Major Sources of Greenhouse Gas Emissions In 2010, global greenhouse gas emissions from the agricultural sector totaled 4.7 billion tons of carbon dioxide (CO₂) equivalent, up 13 percent over 1990. Agriculture is the third largest contributor to global emissions by sector, following the burning of fossil fuels for power and heat, and transportation.

1. the suns rays reach the earths surface without any proble The primary anthropogenic sources are combustion of fossil fuel, and the decomposition of organic materials associated with wetlands, rice paddies, and livestock manure. Nitrous oxide also occurs in low concentrations relative to carbon dioxide, but it is 230 times more efficient as a greenhouse gas. These factors combine to make it a 6% contributor to total the greenhouse effect. The primary anthropogenic sources are fossil fuel combustion, fertilizers, and deforestation. The only major greenhouse gases that are not naturally occurring are the chlorofluorocarbons. They come solely from anthropogenic sources such as the production and/or use of foams, aerosols, refrigerants, and solvents. They are present at an extremely low concentration in the atmosphere, however they are 15,000 times more efficient as a greenhouse gas relative to carbon dioxide.

- The 'blanket' here is a collection of atmospheric gases called 'greenhouse gases' based on the idea that the gases also 'trap' heat like the glass walls of a greenhouse do. These gases, mainly water vapor (), carbon dioxide (), methane (), and nitrous oxide (), all act as effective global insulators. These gases (water vapor, carbon dioxide, methane, ozone, and nitrous oxide) are referred to as greenhouse gases.. 2  Albedo has an important influence on the earth's temperature.
