Over the past 50 years, atmospheric carbon dioxide concentrations have increased from approximately 320 parts per million (ppm) in 1958 to approx. 400 ppm (parts per million) or 0.04% in 2013.
See the link below for a detailed figure (Figure 1, the one most to the right) based on 7 different global measuring locations.
Also included is a link to an informative video on CO2 increase over the past 800,000 years to today, from the Mauna Loa, Hawaii atmospheric monitoring station.

What has happened to global temperatures as atmospheric levels of carbon dioxide have increased?
They both have increased.
True or false does atmospheric carbon dioxide concentrations meaured at Mauna Loa the lowest during the summer?
true
Why are atmospheric concentrations of carbon dioxide are expected to increASE doing the future?
Idk why don't you just google it dummy
What atmospheric element has increased in the atmosphere since the beginning of the Industrial Revolution?
Carbon Dioxide
Is it true that increased levels of atmospheric carbon dioxide are largely due to the increased amount of aerobic respiration by plants and animals?
No. This is part of the carbon cycle, which is a closed system and does not increase or reduce the atmospheric concentration of carbon dioxide. The only way to increase the level of atmospheric carbon dioxide is to bring carbon from outside that system. Volcanic eruptions can add a relatively small amount, but the main source of new carbon is from burning fossil fuels, such as coal, oil and natural gas.
What is a hypothesis and what are some examples?
Increased levels of atmospheric carbon dioxide might cause global warming.
What gas is 20 times better at collecting heat than carbon dioxide?
Methane blocks heat radiation twenty times more effectively per molecule than does carbon dioxide. Fortunately, atmospheric methane concentrations are very much lower than carbon dioxide.
How has human activity affected atmospheric chemistry?
The burning of fossil fuels has dramatically increased the percentage of carbon dioxide in the atmosphere
What Large amounts of atmospheric carbon dioxide are absorbed by what?
The ocean absorbs large amounts of atmospheric carbon dioxide, and is acidified thereby.
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.
What is the relationship between the rise of ocean temperatures and the rise in the level of atmospheric carbon dioxide?
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
What is an increase in the atmospheric levels of carbon dioxide is the biggest contributor?
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.
