CO2 provides approximately .03% of the earth's atmosphere. If you consider that the earth's atmosphere contains approximately 4.2 billion cubic kilometers - which is the "effective mass" of the atmosphere, or the mass of the entire atmosphere if measured at sea level pressure - then:
4.2 billion x .03 % = 1,260,000 cubic kilometers of CO2.
The other constant used in this equation is the "Karman Limit" of 100 miles as the upper boundary for earth's atmosphere.

Why are temeratures of earth and moon so different?
Because the moon has an incredibly small atmosphere, if it has any that is. The earth has a very big atmosphere compared to the moon. Thanks to all the CO2 in the atmosphere of earth, we are able to retain a really large amount of heat, unlike the incredible lack of any gas on the moon.
What Is a state of the atmosphere at any given time and place?
Weather.
Why is the surface temperature on Venus so much higher than that on earth?
Venus' atmosphere consists mainly of Co2 (Carbon dioxide), while Earth's atmosphere is Co2 and oxygen. Co2 is much denser than oxygen, so it holds more heat from the sunlight. This trapping of heat by gases is known as the "greenhouse effect", and while we are experiencing a small amount of it on Earth, Venus has a higher concentration of Co2, making the effect MUCH more severe. The effect is also more severe because Venus is closer to the sun.
Why does not moon have atmosphere?
Actually the Moon has a very faint atmosphere.The big difference between Earth and Moon is the respective sizes, and masses. The Moon has much less gravitational attraction; as a result, any molecules in an atmosphere can easily escape into outer space, in a relatively short time. The atmosphere "boils away", so to speak.
What is the relationship between the moon surface gravity lack of atmosphere and temperature range?
The Moon's gravity causes the lack of atmosphere (any possible atmosphere evaporates out into space in a fairly short time); and the lack of atmosphere causes the extreme temperatures.
How is carbon in any form given out in the atmosphere?
It enters our atmosphere through dead animals, tress and any decaying or burning item that lived. It is believed by some that the change in our atmosphere of concentrations of CO@ may be as high as 0.007%. Some feel this number is wildly high.Oceans provide the largest sink for absorbing this CO2 from our air. Forests provide the largest generator for CO2. Man produces roughly 6% of all CO2 in our atmosphere.
Is too much co2 bad for the atmosphere?
co2 creates a green house effect that warms up the Earth by trapping in heat. Yes this green house effect has increased the earths temperature little bit in the past million years or so, but in our lifetime we wont see any dramatic changes.

Why was Hawaii chosen as a site to measure carbon dioxide levels in the atmosphere?
- carbon dioxide is a green house gas - determinations of carbon dioxide in the atmosphere are important for the study of climate changes, especially for the evolution of temperatures - determinations of carbon dioxide in the atmosphere are also important for the study of seas/oceans acidity (and of course for marine biology) because CO2 is easily absorbed in water
Why is the atmosphere of Venus more friendly to planets than humans?
The atmosphere of Venus could be thought of as being more friendly to plants than to humans, but such high levels of CO2 trap so much heat that the runaway greenhouse effect would burn any Earth plants to cinders in short order.
What large region of the atmosphere where the air has similar?
what the lower atmosphere is like at any given place and time
Why is the burning of fossil fuels so harmful to the environment?
Because it adds carbon dioxide (CO2) to the earth's atmosphere without removing any. And the amount of CO2 in the atmosphere is highly influential on earth's climate as scientists have learned when studying earlier episodes of warming and cooling over the past 650,000 years. Our planet has a very ingenious and natural system of controlling CO2: its called the Carbon Cycle. In the Carbon Cycle natural elements like vegetation, soil and oceans not only releases lots of CO2 into the atmosphere, they also re-capture it from the atmosphere thereby creating a balance. These natural elements are called Carbon Sinks. The problem is that we humans, by burning fossil fuels such as oil, natural gas and coal, only add CO2 to the atmosphere, we do not remove any. While the natural Carbon Cycle is able to capture some of man-made CO2 (about 40% at present), it cannot capture all and the remaining 60% stays in the earth's atmosphere. This natural capacity to remove man-made CO2 is also negatively affected by deforestation as the trees and plants removed by humans will no longer be able to capture both natural- as man-made CO2, thereby further increasing the total amount of CO2 in the atmosphere. Another related and direct environmental problem is the acidification of our oceans. Oceans are an important carbon sink and as they store more man-made CO2, their water becomes more acid which in turn will have consequences for sea-life and the food-chain.

Why oxygen and carbon dioxide are not the most abundant gases in the atmosphere?
Oxygen readily combines with many other elements, carbon (CO2), hydrogen (water), iron (rust), etc. So absent photosynthetic life we would not expect there to be much oxygen in any atmosphere. CO2, on the other hand, ought to be fairly high, and it most probably was early in earth's history. However, living organisms began pulling the CO2 out of the atmosphere, cracking it, and releasing the O2. The carbon taken up by these marine organisms was incorporated into their shells and exoskeletons. When they died they sank to the sea floor, forming vast chalk and limestone deposits over hundreds of millions of years. Much of the early earth atmospheric CO2 ended up in limestone deposits. This left nitrogen as the most predominant gas.
Why is limestone cooled in a dry argon atmosphere after being heated?
Limestone, when heated produces calcium oxide (CaO) and carbon dioxide (CO2). CaO is highly reactive and will combine with CO2 from the atmosphere to reverse the above process. It will also react with any water vapour in the atmosphere to form calcium hydroxide (CaOH). These reactions can be prevented by allowing the CaO to cool in an inert environment such as that provided by argon.

Is there any atmosphere around mars?
Yes. Its atmosphere is much less dense than the Earth's, but still present.
