Carbon dioxide levels in the atmosphere in 1910 were around 290 ppm (parts per million). One hundred years later levels are now approaching 400 ppm. This is an increase of 38%.
See a simple graph at the link below.
That depends on how you measure, where you are and what data you use.
The most common method of stating this is to use the 1900 data in Antarctic through glacial samples. This is 278 ppm
The current source is through multiple data points worldwide, which is about 380 ppm
This represents a change in our atmosphere of 0.011% in terms of total concentrations.
Using Greenland data from 1900 glacial sample to present Greenland sample we see no change in CO2 levels.
If we use specific sites, such a Manua Loa we can not go back as far as 1900, but we have seen changes much higher then the 0.011% of our first sample.
In terms of total greenhouse gases, CO2 makes up about 20% of our greenhouse gases. Man produces about 6% of all CO2. Water Vapor makes up the remaining 80% and there are some trace gases that make up the variances.
The level of carbon dioxide has been rising since the beginning of the Industrial Revolution in the early 1800s. Within the last 100 years (since about the time of World War 1) the rate of this rise has been increasing.
Carbon dioxide levels have risen from around 280 ppm (parts per million) to over 400 ppm.
This is largely caused by the burning of fossil fuels (coal, oil and natural gas), which burning releases carbon dioxide that has been underground for more than 300 million years, when the fossil fuels formed.
Carbon dioxide levels have increased from around 280 ppm to over 400 ppm.

Ground level carbon dioxide is a pollutant. It reaches to atmosphere by westerly's.
Carbon dioxide is decreased.
Trees and plants inhale carbon dioxide and let out oxygen thus increasing the oxygen level and not the carbon dioxide level.
If the level of carbon dioxide increases, the repiratory centers are signaled to increase the rate and depth of breathing. This will result in the return of normal CO2 (carbon dioxide) and slows the breathing rate.
Carbon dioxide (CO2) is a gas that mixes very easily, so there are no regional variations. So the carbon dioxide level in Bangladesh is the same as it is all round the world.The carbon dioxide levels for 2012 are 392 ppm (parts per million).
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.

The pure and dry carbon dioxide gas has no pH level.
Low level of carbon- dioxide and more level of oxygen.

The relationship between the rise of ocean temperatures and the rise in the level of atmospheric carbon dioxide is that when there is a rise in atmospheric carbon dioxide the warmer the temperature of the ocean is
