How much has co2 increased in the atmosphere in the past 150 years?
Almost doubled (from .2 to almost .4)
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 caused the proportion of oxygen in the atmosphere to increase?
Plants started to grow on the earth, plants breath in carbon dioxide (which is why it decreased so much) and they breath out oxygen. That is why the percentage of oxygen has increased so much.
Is the current oxygen content of the atmosphere lower or higher or about the same as is was millions of years ago?
About the same. About a half billion years ago it was significantly higher, and more than a billion years ago it was lower, much lower. Before 1.5 or 2 billion years ago there was no free oxygen in the atmosphere, before 3 billion years ago there wasn't any.
What would happen if the carbon dioxide in the atmosphere decreased?
The atmosphere would become much smaller and the earth would become much colder during winter and also at night.
