Prior to humans, it was volcanoes. But humans currently emit over 100 times as much as volcanoes do on an annual average basis, and this is partially because volcanic activity has been low in the recent past.
It also matters how we view the issue. If we view man's contributions in total verses natures contributions in total, nature produces 94% of the total CO2 produced. Some of man's 6% would belong to nature had we not burned the wood or ate the growth before it decayed.
What else can I help you with?
What percentage of carbon dioxide is in mars atmosphere?
About 95.3% of Mars' atmosphere is composed of carbon dioxide.
Which Planets have atmosphere mostly carbon dioxide?
Venus and Mars haveatmospheres mostly consisting ofcarbon dioxide.
Carbon in the atmosphere is most often found as which of the following compounds?
List the compounds so I can answer your question. I would imagine Carbon Dioxide and Carbon Monoxide would be the first 2.
What planet has a thick carbon dioxide atmosphere?
Venus has a thick carbon dioxide atmosphere, making up about 96.5% of its atmosphere. This high concentration of carbon dioxide contributes to the intense greenhouse effect on the planet, resulting in surface temperatures hot enough to melt lead.
How is the balance mainted between the volume of carbon dioxide and oxygen in atmosphere?
The balance of oxygen and carbon dioxide is maintained in the atmosphere by the oxygen released by plant during photosynthesis and carbon dioxide released by human ,animal's etc in the atmosphere
Which country is the world largest emitter of carbon dioxide in the atmosphere?
China is the world's largest emitter of carbon dioxide in the atmosphere, followed by the United States and India.
What nation is the largest emitter of carbon dioxide?
What nation is the largest emitter of carbon dioxide?
What is one of earths largest carbon sinks?
One of Earth's largest carbon sinks is the ocean. The ocean absorbs a significant amount of carbon dioxide from the atmosphere, storing it in marine plants, animals, and sediments. This helps regulate the amount of carbon dioxide in the atmosphere and mitigate the impacts of climate change.
Does carbon dioxide sink or rise in the atmosphere?
Carbon dioxide rises in the atmosphere.
What is the source of carbon dioxide for water plants?
Carbon dioxide in the oceans primarily comes from the atmosphere. Some of the carbon dioxide from the air dissolves into the ocean water. However, smaller amounts can come from respiration of sea animals and other miscellaneous sources. The atmosphere is by far the largest source of carbon dioxide in ocean water, though.
Plants depend on the atmosphere for the largest source of?
Plants depend on the atmosphere for the largest source of carbon dioxide, which they use during photosynthesis to produce sugars and oxygen.
What molecule carries most of the carbon in the atmosphere?
Carbon dioxide (CO2) is the molecule that carries most of the carbon in the atmosphere.
Does Soils emit carbon dioxide into the atmosphere?
Yes, I think soil can emit carbon dioxide into the atmosphere.
The process of decay releases carbon dioxide into the atmosphere?
The process of decay releases carbon dioxide into the atmosphere
How could cutting down trees lead to the build up of carbon dioxide in the atmosphere?
Trees absorb carbon dioxide from the atmosphere during photosynthesis. When trees are cut down and not replaced, this carbon dioxide is no longer absorbed, leading to an increase in its levels in the atmosphere. Additionally, when trees are burnt or decompose, the stored carbon is released back into the atmosphere as carbon dioxide.
Carbon is stored in the atmosphere in the form of what molecule?
Carbon is stored in the atmosphere primarily as carbon dioxide (CO2) molecule.
What the from of carbon in the atmosphere?
Most of the carbon in the atmosphere is in the form of carbon dioxide, (CO2) gas.
