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.

- Carbon Dioxide. Carbon dioxide (CO2), which comes mainly from burning fossils fuels, is one of the top three greenhouse gases. Though not as high on the GWP scale as methane, CO2 accounts for the majority of greenhouse gas emissions in the United States -- 85 percent, noted Koerner.Vehicles are the biggest contributor.ethane, which comes from natural gas, landfills and cow flatulence, is one of the top three greenhouse gases, according to the Popular Science website. Methane has a Global Warming Potential (GWP) rating of 21.

Greenhouse gas A greenhouse gas (sometimes abbreviated 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.Without greenhouse gases, the average temperature of Earth's surface would be about 15 °C (27 °F) colder than the present average of 14 °C (57 °F).he main sources of greenhouse gases due to human activity are: 1  burning of fossil fuels and deforestation leading to higher carbon dioxide concentrations in the air. 2  Land use change (mainly deforestation in the tropics) account for up to one third of total anthropogenic CO 2 emissions.

Natural and anthropogenic variations in methane sources during the past two millennia Methane is an important greenhouse gas that is emitted from multiple natural and anthropogenic sources. Atmospheric methane concentrations have varied on a number of timescales in the past, but what has caused these variations is not always well understood.ethane is an important greenhouse gas that is emitted from multiple natural and anthropogenic sources.

- By. Tweet. Berry Gordy founded the Tamla label today (January 12, 1959), with an $800 loan from his family. Berry Gordy got the bug to be in the music industry around 1953, when he founded his first business, the 3-D Record Mart – House of Jazz. The business failed, so Berry Gordy got a job supporting himself and his 19-year-old wife, by working at the Ford Lincoln-Mercury plant.

- Of 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.hese 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.

Does a Hybrid Emit More Greenhouse Gases Than an Internal Combustion Engine? Carbon dioxide from the burning of fossil fuels for both energy (coal) and vehicles (gasoline) makes up the majority of anthropogenic greenhouse gas emissions. The overall effect of greenhouse gas accumulation is to increase global average temperatures.

- Scientists say that because carbon dioxide is a greenhouse gas, it is this increase that has caused average global temperatures to rise. So the question is whether this increase in atmospheric carbon dioxide and the resultant temperature rise are caused by human activities, and are therefore anthropogenic.

Effects of increased greenhouse gas emissions The main increased greenhouse gas emissions is global warming. Carbon dioxide, methane, nitrous oxide and fluorinated gases all help trap heat in the Earth's atmosphere as a part of the greenhouse effect. The Earth's natural greenhouse effect makes life as we know it possible.

What is the difference between natural and anthropogenic sources of greenhouse gases? This in turn adds a little more to the greenhouse effect and therefore to global warming, providing an example of positive feedback. So, the essential difference is that anthropogenic sources increase the atmospheric concentration of greenhouse gases and create an enhanced greenhouse effect.he burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases Carbon Dioxide (CO2).Methane released from cat … tle rearing as well as other agricultural practices.Carbon dioxide released from cement manufacturing.

- More of this gas equals more warming. The atmospheric gases primarily responsible for the greenhouse effect are known as greenhouse gases and include water vapor, carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O). The most prevalent greenhouse gas is CO 2. Some atmospheric CO 2 is natural.

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 Behind the struggle to address global warming and climate change lies the increase in greenhouse gases in our atmosphere. 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.he greenhouse effect, in turn, is one of the leading causes of global warming. The most significant greenhouse gases are water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O), according to the Environmental Protection Agency (EPA).

Dairy production has a considerable effect on climate change due to emissions of greenhouse gases such as methane, nitrous oxide, and carbon dioxide. In the US, the greatest sources of these emissions in milk production include feed production, enteric fermentation and manure management.mpacts. Dairy cows add substantial amounts of greenhouse gases to the atmosphere. In some places they contribute to the conversion of natural habitat to agricultural land due to the increasing demand for feed crops such as corn, alfalfa and soy.
