Why have carbon dioxide levels in the earth fallen?
Carbon dioxide levels have not fallen. They have been gradually increasing for the past 250 years when man began burning fossil fuels and cutting down trees. Since 1980 CO2 levels have increased more rapidly than ever before.
How do scientist discover information about the earth's past?
using lots and lots of testing to prove facts about the earth's past.
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 are the levels of carbon dioxide from past to present?
During the past 500,000 years, levels of carbon dioxide in the atmosphere never rose above 300 ppm (parts per million) or 0.03%. Since the Industrial Revolution, 200 years ago, when we began burning coal, levels have risen to their present (2013) levels of 400 ppm (parts per million) or 0.04%.
What does the word archaelogoist mean?
