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%.

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).
What is the carbon footprint of the average American?
The carbon footprint of the average American is around 16 tons of carbon dioxide per year.
Does the amount of carbon dioxide in the atmosphere go up every year?
Yes, the amount of carbon dioxide in the atmosphere has been increasing annually due to human activities such as burning fossil fuels and deforestation. This increase in carbon dioxide is a significant driver of global climate change.
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).
How common is carbon dioxide in the air?
Levels of carbon dioxide in the air reached 400 ppm (parts per million) or 0.04% this year (2013). This is the highest level in the past 500,000 years.
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 carbon is released each year from burning fossil fuels, and where does it go?
Approximately 36 billion metric tons of carbon dioxide are released each year from burning fossil fuels. This carbon dioxide is released into the atmosphere, where it contributes to the greenhouse effect and climate change.
How much carbon is released into the atmosphere each year by fossil fuel's?
Approximately 36 billion metric tons of carbon dioxide are released into the atmosphere each year from burning fossil fuels. This significant amount of carbon dioxide is a leading contributor to the greenhouse effect and global warming.
Carbon dioxide is produced by one person?
Answer:On average, world wide it is about 4 tonnes per person per year. The USA is top of the list at 20 tonnes per capita per year.See link for data on all countries
How much carbon is released each year from burning fossil fuels?
Approximately 36 billion metric tons of carbon dioxide are released each year from burning fossil fuels.
Why does the carbon dioxide level fluctuate during a single year?
The carbon dioxide level fluctuates during a single year due to seasonal changes in plant growth and decay, which affect the amount of carbon dioxide absorbed and released into the atmosphere.
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 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 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.
What is the carbon footprint of the average American?
The carbon footprint of the average American is around 16 tons of carbon dioxide per year.
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.
