The oceans contain 37,400 billion tons (GT) of suspended carbon, land biomass has 2000-3000 GT. The atmosphere contains 720 billion tons of CO2 and humans contribute 40 billion tons per year. The oceans, land and atmosphere exchange CO2 continuously so the additional load by humans is small, on an annual basis.
Over the past century humans have, however, raised atmospheric CO2 levels from 290 ppm to nearly 400 ppm. At the present rate we will pass 500 ppm before 2050, an increase of nearly 60%.

∙ 13y agoThe air around you is made up of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide with respect to volume. The composition of what you exhale has 4-5% CO2. Since we can't count the same CO2 twice we will ignore the inhaled amount, as it is still present in the exhaled figure. So our equation should look like this.
CO2 exhaled = (Volume of breath) x (breaths taken per hour) x (hours per day) x (days per year) x (population of planet) x (percent of breath that is CO2)
Alright, let assign some values to these:
- Volume of Breath = about 500cc
- breaths per hour = 960
- hours per day = 24
- days per year = 365
- population of planet = 6,775,235,741
- percent of breath that is CO2 = 5
co2 exhaled =1.42442556 × 10^18 or 142442556000000cc
OR
142442556000000 Litres
OR
142442556000 cubic metres
But really I suppose that means nothing unless put into perspective. If contained into Olympic sized Swimming Pools, it would take
56 977 022 to hold it all. Might seem like alot, but really it's not if you consider the size of what it is to be compared to.

On average humans breathe out about 0.85kg of CO2 each day, or 310kg/year.

How much automotive exhaust is produced by cars each year?
Vehicle exhaust is mostly carbon dioxide, with a little water, carbon monoxide, hydrocarbons, and nitrogen oxides. This answer deals with the carbon dioxide content only.Sixteen percent (16%) of human carbon dioxide greenhouse gas emissions comes from road transport (cars, trucks and buses). Cars are responsible for about half of this (8%).Humans are responsible for around 35 billion tonnes of carbon dioxide emissions every year.Car emissions, 8% of that total, is around 2.8 billion tonnes of carbon dioxide (2,800,000,000).
How much carbon dioxide does a bus emit?
A small bus can emit 270 grams of carbon dioxide per kilometre. (Australian figures). This might be the equivalent of about 21 tonnes of Carbon dioxide (CO2) a year for a bus driving 60,000 km (36,000 miles).
What did Charles David Keeling discover by measuring carbon dioxide in the atmosphere?
Charles David Keeling discovered that: - the concentration of carbon dioxide in atmosphere has an important seasonal variation - after 1960 he discovered that the concentration of carbon dioxide in atmosphere increase year after year, caused very probable by anthropogenic activities
Does trees absorb carbon monoxide?
Carbon Monoxide: is a colorless, odorless, tastless gas that when inhaled is toxic to humans. Carbon Monoxide: is a byproduct of a rich mixture fire, Burning wood, Gas fires, etc. Your answer is No! Trees use Carbon Dioxide which is what you release when you exhale. So-Live long.
Do forest fires release carbon dioxide?
The amount of carbon dioxide emitted each year varies according to the amount of forest burnt. However, there is no net increase in atmospheric carbon dioxide from forest fires, as long as the forests are allowed to recover and regrow.AnswerVery little, compared to human emissions. It's hard to say exactly... It is 25.687%, approximately, it is 25.7%it is 25.687%
What gas is produced when coal is burned?
Carbon dioxide (CO2)!It produces sulfuric oxides. (This was written by a 12 year old.)

How much Co2 do the trees in the Amazon rainforest make a year?
Amazon rainforest trees don't make carbon dioxide, they take it in. The Amazon rainforest absorbs 1.5 billion tons of carbon dioxide from the atmosphere every year.
How much carbon dioxide does a bus emit?

How does the process of photosynthesis affect carbon dioxide concentrations in the atmosphere during a typical year?
Photosynthesis uses carbon dioxide as a raw material where carbon dioxide is fixed into organic molecules. This process lowers the level of carbon dioxide in the atmosphere. The seasonal fluctuation of carbon dioxide levels during a year may be caused by increased photosynthesis during spring and summer.
How much carbon dioxide is the US releasing into the atmosphere every year?
According to Wikipedia's List of countries by carbon dioxide emissions the US emits 5,838,381,000 metric tonnes annually, which is 19.91% of the global total (Figures from 2007).
How much co2 does a tree absorb per year?
Almost half the mass of a tree is carbon, taken from the atmosphere in the form of carbon dioxide. A tree only takes in carbon when it is growing, and the amount that a tree grows in a year varies from tree to tree. Old trees are bigger and grow more than young trees in a year, usually.

How much Co2 does running a TV produce?
A flat panel television does not produce any carbon dioxide during normal operation. The carbon footprint of operating an LCD TV is estimated at 215 kg per year on average.
How much carbon dioxide is produced in average by an industry each year?
The answer varies widely. The fossil fuel industry is ultimately responsible for 30 billion tons of CO2 emissions per year. It would be more, but a bit of it is captured and sequestered. Then therevis overlap, as some of the oil and gas produced by the petroleum industry might be used for maintenance and development of geothermal energy supplies.
How much CO2 is lost to space every year?
Very little. Carbon dioxide is ingested by plants, which require it. When we eat the plants, some of the carbon is exhaled as CO2. The Earth is essentially a closed system; the carbon that is here on Earth will remain here on Earth. Carbon dioxide is a natural part of our atmosphere, and is present in only trace amounts.
Does trees absorb carbon monoxide?
