By how much have carbon dioxide emissions increased its atmospheric percentage over the past 250 years?

CO2 levels were about 260-280 ppm immediately before industrial emissions began and did not vary much from this level during the preceding 10,000 years.
The concentration of carbon dioxide (CO2) in Earth's atmosphere has reached 391 ppm (parts per million) as of October 2012.
((391-260)/391)*100 = 33.50
Thus there has been a 33.5% increase in the levels of CO2 in Earth's atmosphere over the past 250 years.

What has happened to global temperatures as atmospheric levels of carbon dioxide have increased?
They both have increased.
Why is the increase of atmospheric carbon dioxide less than the amount of carbon dioxide emissions produced by burning of fossil fuels?
Because trees consume carbon dioxide and produce oxygen.
What is composition of atmospheric air at sea level?
oxygen, nitrogen, hydrogen, carbon dioxide,moisture, carbon monoxide, dust .. less percentage of other gases.....
Carbon dioxide in atmospheric air amounts to about?
Carbondioxde in atmospheric air amount to about 0.04%.
How does urban sprawl increase carbon dioxide emissions?
Urban sprawl creates and increases carbon dioxide emissions via more vehicles on the roads. More people means more transportation needed. More vehicles on the road creates more carbon dioxide emissions.
How has human activity affected atmospheric chemistry?
The burning of fossil fuels has dramatically increased the percentage of carbon dioxide in the atmosphere
Why do environmentalists believe that carbon dioxide emissions have increased?
At this time we are seeing rapid industrialization in China and India; conservation measures in the western world have not come close to offsetting the increased emissions from developing economies. Carbon dioxide emissions have increased.
What has happened to global temperatures as atmospheric levels of carbon dioxide have increased?
They both have increased.
What percentage of carbon dioxide emissions in the US are due to buildings?
12%
What atmospheric element has increased in the atmosphere since the beginning of the Industrial Revolution?
Carbon Dioxide
Why is the increase of atmospheric carbon dioxide less than the amount of carbon dioxide emissions produced by burning of fossil fuels?
Because trees consume carbon dioxide and produce oxygen.
What is a hypothesis and what are some examples?
Increased levels of atmospheric carbon dioxide might cause global warming.
Is ozone depletion an activity that is responsible for the largest percentage of human-made carbon dioxide emissions?
Actually the questions must be the other way round that is the largest percentage of human-made carbon dioxide emissions responsible for ozone depletion. But still carbon dioxide is not the only reason for the ozone depletion. Various other factors such as freons, CFC's etc are responsible for ozone depletion.
What are the global problems of clearing forests and increased gas emissions from factories and motor vehicles?
The main global problems of clearing forests and increased gas emissions are global warming and acid rain. The clearing of forests means additional carbon dioxide in the atmosphere, causing global warming. Increased gas emissions also contribute to global warming and acid rain.
What do you inhale when breathing?
Oxygen gas (when we exhale, we breathe out 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 might decrease global atmospheric carbon dioxide?
There is no known way that humans can economically remove carbon dioxide from the atmosphere; all we can really do is reduce our emissions of carbon dioxide and slow down the rate at which atmospheric carbon dioxide levels are increasing. The surface waters of the ocean do absorb some carbon dioxide from the atmosphere as atmospheric carbon dioxide level increase, but there is little interchange betwen the warm upper ocean and the deep layers. However over a period of several thousand years, there is sufficient interchange to absorb large volumes of carbon dioxide, allowing the atmospheric concentration to return more or less to normal. Afforestation. Planting trees will remove carbon dioxide from the atmosphere.
