In May 2013, carbon dioxide levels reached 400 ppm (parts per million). This is 0.04%.
There are seasonal changes in levels each year. Highest in May (after the northern winter, when plants are dormant) and lowest in October.

Scientists suggest our target should be 350 ppm (parts per million) or less.
A:CO2 varies slightly in a yearly cycle, and is also increasing steadily due to anthropogenic (man-made) emissions.Carbon dioxide is a well-mixed gas. This means that it doesn't matter where it is measured, it will show the same value because (on average) it is evenly distributed throughout the globe.
A:In 2011 Carbon dioxide is present in the earth's atmosphere at about 385 parts per million by volume or 582 parts per million by mass. It is usually stated in ppm to reduce decimal and "0" confusion. This would be the same as 0.000 385 (by volume) and 0.000 582 (by mass ) as decimal fractions and 0.0385% (by volume) and 0.0582% (by mass)According to the Wikipedia's math this is 3.0×1015 kg (3 000 gigatonnes) of the earth's 5.14×1018 kg (5 140 gigatonnes) total atmosphere.
A:This may not sound like much, but it has a powerful greenhouse effect. Considering it would be under 300 ppm without human emissions, this is a considerable upset in the balance of this greenhouse gas, and scientists anticipate earth's climate will continue adjusting to the current level for centuries yet to come. The length of time required for adjustment is known as "climate sensitivity."There are also several free iPhone climate applications such as CliMate Mobile were you can view weekly CO2 data from NOAA reporting stations. This data goes back to 1880 in detail, and more granularly (less precise) many millions of years.

Historic levels are taken from glacial samples drilled in Antarctica. They show levels varied between 200 and 280 with regular intervals of about 100K years. The most recent glacial samples show levels around 280 ppm.
What else can I help you with?
How can we easily detext fixed air today?
Fixed air, historically referred to as carbon dioxide (CO2), can be easily detected today using several methods. Commonly, gas sensors or infrared spectroscopy are employed to measure CO2 concentrations in the air. Additionally, chemical indicators that change color in the presence of CO2 can provide a simple visual detection method. These tools are widely used in various applications, from environmental monitoring to industrial processes.
What happens when liquid co2 is exposed to air?
When liquid CO2 is exposed to air, it quickly evaporates and turns into gaseous CO2. This process is known as sublimation. The gaseous CO2 will mix with the air in its surroundings.
How do you figure ppm of CO2 in the air?
To calculate the parts per million (ppm) of CO2 in the air, you would measure the concentration of CO2 in the air using a CO2 sensor or monitor, and then divide that by the total volume of the air sample. This would give you the ppm of CO2 in the air sample. Common methods include using infrared gas analyzers or chemical absorbents.
How can we easily detect fixed air today?
Fixed air, historically referred to as carbon dioxide (CO2), can be easily detected today using various methods. One common technique is using infrared gas analyzers, which measure the absorption of infrared light by CO2 molecules. Additionally, simple chemical indicators, such as limewater, can be used where the solution turns cloudy in the presence of CO2. Portable electronic sensors and handheld gas detectors also provide quick and accurate readings of CO2 levels in various environments.
How is co2 in the air useful to plants?
The plants use CO2 from air for photosynthesis. The air entering into its leaves through stomata comes in contact with photosynthetic cells and diffuse CO2 for assimilation to form carbohydrates.
What CO2 level is acceptable in normal breathing?
In normal breathing, the acceptable level of carbon dioxide (CO2) in the air is typically around 0.04% (400 parts per million). In human physiology, the concentration of CO2 in exhaled air is much higher, usually around 4-5%. While elevated CO2 levels in the environment can indicate poor air quality, concentrations below 1% are generally considered safe for normal breathing.
How does air pollution affect the ecosytem?
Air pollution has adverse effects on the ecosystem. # If the level of CO2 rises in the atmosphere, it causes greenhouse effect. As a result, global warming is a threat we all face today. # CFCs which are air pollutants can damage the ozone layer. # Rainfall is affected due to air pollution
What is the function of a CO2 sensor and how does it contribute to monitoring air quality?
A CO2 sensor measures the level of carbon dioxide in the air. It helps monitor air quality by detecting high levels of CO2, which can indicate poor ventilation or the presence of pollutants. This information can be used to adjust ventilation systems and improve indoor air quality.
Why is the CO2 level high in the atmosphere?
The CO2 level is high in the atmosphere primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release large amounts of carbon dioxide into the air, leading to an increase in atmospheric CO2 levels.
What happens to the carbon dioxide level during hyperventilation in fresh air?
CO2 drops during Hyperventillation

How does C02 travel around the world?
CO2 is in the air and as the air moves so does the CO2 in it.
Is CO2 denser than air?
Yes, carbon dioxide (CO2) is denser than air.
Does air conditioners have co2 in it?
Air conditioners do not contain CO2 as a refrigerant. Typically, air conditioners use refrigerants such as hydrofluorocarbons (HFCs) or hydrochlorofluorocarbons (HCFCs) which are not the same as carbon dioxide (CO2). CO2 is not commonly used in air conditioning systems due to its properties.
Why is it a problem for carbon dioxde to be released in to the atmosphere?
It really is not a problem. Currently CO2 levels are at a global level of 0.037%. Nature produces the vast bulk of this CO2 and life would stop on the planet if level dropped to 200 PPM. If you look at the Vostok webiste (where we get our old climate data from) one of the complaints that science experts have is the level of CO2 is too low! Only 280 PPM. Without CO2 the planet would be extremely cold and quite dead. Our oceans, which collect most of the CO2 from or atmosphere, do an awesome job of pulling the CO2 out of the air!
What can be done to stop CO2 getting into the air?
the first and fore most is to stop cutting trees, as when we give out carbon dioxide {CO2} the trees take co2. but when trees will not be there , co2 will be in the air.
