They measure it from bubbles of gas trapped in Antarctic ice.
Primarily by the scientific examination of Ice Core Samples taken thousands of feet Deep from thousands of Sites around Earth.
It is an interesting process really. When ice freezes, it has very tiny atmospheric gas bubbles trapped in the ice. There is a place in the Antarctic, known as Lake Vostok, that we are able to take and drill down very deep and get very clean samples of what the air was like. These samples will tell us what the atmosphere was like at a given time, by how far down the sample was taken from. From these cores, we are able to get actual gas bubbles of atmosphere from up to 650,000 years ago.

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.
What are large amounts of atmospheric carbon dioxide absorbed by?
The ocean absorbs large amounts of atmospheric carbon dioxide, and is acidified thereby.
Which increase in atmospheric carbon dioxide contributes to global climate change?
Any increase in atmospheric carbon dioxide contributes to global climate change.
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to What?
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.
What is the dominate atmospheric gas on mars?
carbon dioxide.
Where was atmospheric carbon dioxide first collected on a consistent basis?
Scientists and meteorologists only started serious atmospheric studies around 150 yeas ago.
Why do some scientists theorize that global warming not be the result of increases in atmospheric carbon dioxide?
Many scientists hypothesize that deforestation intensifies global warming trends.
Are greenhouse gases just a theory?
Greenhouse gases do exist and are not just a theory. Scientists have known for hundreds of years that some atmospheric gases (water vapour, carbon dioxide, methane and others) absorb heat rising from the surface of the earth.
What do scientists think is causing the earth's atmospheric temperature rise?
Scientists think that human burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity (which releases carbon dioxide (CO2)), is causing the atmospheric temperature rise.
What has the author A M Campbell written?

Campbell has written: 'Emission inventory of atmospheric sulphur dioxide and nitrogen dioxide pollutants within the Province of Manitoba for 1981 and 1982' -- subject(s): Atmospheric nitrogen dioxide, Atmospheric sulphur dioxide, Environmental aspects of Atmospheric nitrogen dioxide, Environmental aspects of Atmospheric sulphur dioxide, Environmental aspects of Factory and trade waste, Environmental chemistry, Factory and trade waste
What Large amounts of atmospheric carbon dioxide are absorbed by what?
The ocean absorbs large amounts of atmospheric carbon dioxide, and is acidified thereby.
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
