Still rising, but currently around 390 PPM. This changes slightly with seasons and locally, but is substantially the same all over the world over time. There are also several free iPhone climate applications such as CliMate Mobile were you can view weekly CO2 data from NOAA reporting stations or going back almost as far as want such as detailed data from 1880 to the present or millions of years.

What is the normal CO2 level for a middle aged male?
The normal range of CO2 for adults is 35-45 mm Hg. This is a measurement of the amount of carbon dioxide (CO2) in our blood. This measurement, along with the levels of oxygen, hydrogen, and bicarbonate allow the determination of one's respiratory status. CO2 is increased in conditions such as asthma, bronchitis, pneumonia, emphysema, and with the use of depressents such as alcohol and other medications. CO2 is decreased in conditions such as hyperventilation, hypoxia, and at times with fever and pain.

How do CaO and CO2 react?
CaO + CO2 ==> CaCO3
What is the current level of CO2 in atmosphere and since when it is above the Upper safe limit?
The current level of CO2 in the atmosphere is around 414 parts per million (ppm). It has been above the upper safe limit of 350 ppm since the late 1980s. Continuing to exceed this limit contributes to global warming and climate change.
Does the presence of CO2 in a solution raise or lower the pH level?
The presence of CO2 in a solution lowers the pH level.
Does the level of CO2 in the atmosphere rise or fall over time?
The level of CO2 in the atmosphere has been rising over time.
Does the level of CO2 rise or fall in a room?
The level of CO2 typically rises in a room as people exhale carbon dioxide.
What is current level of GDP in US?
14.58 trillion USD at 2008 prices.
Does the increase or decrease of CO2 affect the pH level?
Yes, the increase of CO2 can decrease the pH level of a solution, leading to acidification.

How does the brain control breathing?
there's a part of this brain called the respiratory system and if i am not mistaken it is located in a part of the brain called pons and the medulla oblongata. the brain controls the rate of breathing by monitoring the level of carbon dioxide in the blood. CO2 by the way is the main stimulus for breathing. without it, you just stop breathing at all (so CO2 is not at all that bad). anyway, when CO2 levels in the blood is high a condition known as respiratory acidosis develops. as a compensatory mechanism the brain causes us to hyperventilate to get rid of that extra CO2. when the CO2 level is low on the other hand, respiratory alkalosis develops. as a result the brain will cause us to hypoventilate which allows for the accumulation of CO2 in the blood. CO2 is maintained at a normal range which is 35 - 45 mmHg.
How does the global climate respond when the level of CO2 rises or falls?
When the level of CO2 rises in the atmosphere, the global climate tends to warm up due to the greenhouse effect. This is because CO2 traps heat from the sun, leading to higher temperatures. Conversely, when the level of CO2 falls, the global climate may cool down as there is less heat trapped in the atmosphere.
Which gas stimulates us to breathe?
breathing is controlled by the level of co2 in the blood, (not due to the fact that there may be low amounts of o2), there are chemoreceptors that measure the pH level of the blood, remember that co2 can be transported in the blood as carbonic acid, thus this acid lowers the pH. if a low pH is detected, it sends nerve impulses to our brain, that stimulates us to breathe in an effort to get rid of the co2.
Why are scientists concerned about current levels of CO2?
Because CO2 levels are rising and are currently over 390 PPM, and 350 was considered to be the relatively safe number we should not exceed. I think one has to use the most modern and accurate data possible from a variety of sources none of which supports that in 1880 that CO2 was 440 ppm.With rising CO2, it could someday cause a tipping point that would cause runaway temperature rise.
