roughly 11% of CO2 in the atmosphere is contributable to humans' use of fossil fuel. The largest contributor to atmospheric CO2 is biomass degradation from rotting vegetation in rain forests and jungles. CO2 in the atmosphere amounts to only a fraction of 0.1% of the atmosphere, which is primarily Nitrogen (~79%) and Oxygen (~21%).

World's carbon dioxide emission from the use of the fossil fuel 2002?

The worlds carbon dioxide emissions from the use of fossil fuels has decreased since 2002. The United States has had the largest decrease in carbon dioxide emissions.

Why is the increase of atmospheric carbon dioxide less than the amount of carbon dioxide emissions produced by burning of fossil fuels?

Because trees consume carbon dioxide and produce oxygen.

What causes changes in the atmosphere?

emissions from human activity, eg, carbon dioxide from burning fossil fuels.

What percentage of global greenhouse gas emissions come from the US?

In 2009 the US emitted 5420 million tonnes of fossil fuels carbon dioxide. This was 17.8% of the world's total.

Which sector has the highest CO2 emissions from fossil fuel combustions?

Coal has more carbon dioxide emissions than either oil or natural gas.

When humans burn fossil fuels which will increase?

Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change.

What is the thermal equation for coal?

You think probably to capture and storage of carbon dioxide emissions from coal and other fossil fuels.

What advantages does solar energy have over fossil fuels?

Solar energy emits no carbon dioxide emissions. It is free and renewable.

What are the waste products formed from burning fuel?

Burning fossil fuels like gasoline has emissions of carbon dioxide and water.

How is a nuclear power station different to a fossil fuelled power station?

Nuclear power produces clean electricity without any carbon dioxide emissions.Fossil fuel (coal, oil and natural gas) power produces electricity with carbon dioxide emissions which are causing global warming and climate change.

How do biofuels lower carbon emissions?

The steady increase in carbon dioxide concentrations in the atmosphere come from our use of fossil fuels. If we were able to stop using fossil fuels, the amount of carbon dioxide in the atmosphere would stop rising. Biofuels are a partial answer, because by using biofuels you are reducing our use of fossil fuels.

What percentage of Earth's carbon dioxide is produced by burning fossil fuel?

Roughly 0.4% of all carbon dioxide in our atmosphere is blamed on all mankind's contributions. Most of that is through the burning of fossil fuels.

Which fossil fuel can be made to burn cleaner and reduce carbon dioxide emissions if it is combined with purified oxygen?

I dont know :P

Do hybrid cars emit carbon dioxide?

Yes. if they are whole or even partly driven using fossil fuel then they create emissions

What causes global warming apart from vehicle emissions?

Yes, global warming is caused by carbon dioxide emissions from vehicles, but also by deforestation and the burning of fossil fuels (coal, oil and natural gas) in industry, and the generation of electricity, which all releases carbon dioxide.

Which source is better hydroelectricity or natural gas?

Hydroelectricity is better because it releases no carbon dioxide emissions to cause global warming. Natural gas is the cleanest of the fossil fuels (coal, oil and natural gas), but it is still responsible for carbon dioxide (CO2) emissions.

What are the past benefits of fossil fuels?

Fossil fuels (coal, oil and natural gas) were a very valuable source in past, before we realised the effects of their carbon dioxide emissions.

Is carbon dioxide released by fossil fuel formation?

No, formation of fossil fuels (coal, oil and natural gas) removes carbon dioxide from the atmosphere.Burning of fossil fuels releases carbon dioxide.

What is an important source of carbon dioxide emissions that contributes to the greenhouse effect?

Burning fossil fuels like coal, oil and natural gas.

What do Carbon Emissions cause?

Carbon dioxide emissions, from humans burning fossil fuels like coal, oil and natural gas, are building up greenhouse gases in the atmosphere and causing global warming. This is leading to climate change.

How can the environment balance itself against global warming?

The environment balances itself through the carbon cycle, which recycles all the natural carbon from the atmosphere and some of the fossil fuel carbon dioxide. However, it is not able to remove all the emissions from fossil fuels (coal, oil and natural gas), which is why global warming is happening.

Why is the percentage of carbon dioxide in the air so low when so much is given off through burning fossil fuels?

Don't concentrate on how carbon dioxide competes with other gases such as Nitrogen, Oxygen, and Argon in the total percentages but rather the change in the percentage of carbon dioxide in the air over time. It is generally agreed that carbon dioxide levels are higher now than ever before due to fossil fuels.

What causes carbon dioxide?

fossil fuels and breathing causes carbon dioxide :)

What emissions come from fossil fuel power stations?

The burning of fossil fuels in power stations (coal, oil and natural gas) for the generation of electricity, releases carbon dioxide (CO2).

What causes greenhouse emissions?

There are many causes for greenhouse gas emissions, but most are carbon neutral, that is, they release carbon dioxide which was recently removed from the atmosphere, and so make no contribution to global warming. The main ones are:The oceans. Primary source of carbon dioxide, but they consume as much as, or more than, they produce, so, in net terms, no emissions.Dead trees and plants. When plants die, they rot, releasing their stored carbon to form carbon dioxide. But, combined with LIVING trees and plants, no net emissions.Insects, through respiration.Domesticated animals, through respiration (mainly talking about carbon dioxide here, but animals also release methane).Wild animals (not including insects), through respiration.Humans, through respirationIndustrial, non-fossil-fuel carbon dioxide emissions.The causes of emissions that cause global warming are:Burning of fossil fuels (coal, oil and natural gas) in internal combustion engines (all kinds of transport)Burning of fossil fuels to generate electricity.Burning of fossil fuels in industry.Burning of fossil fuels domestically, for heating and cooking.Methane from ruminant animals and also from poor farming practices.Volcanoes.
