How have humans changed the atmosphere of the plants in the past 200 years?
They have increased the levels of the greenhouse gases.(Apex)
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.

How has the amount of CO2 in the atmosphere changed over the past few years?
The amount of CO2 in the atmosphere has been increasing steadily over the past few years. This increase is primarily due to human activities, such as burning fossil fuels and deforestation, which release large amounts of CO2 into the atmosphere. The rising levels of CO2 contribute to global warming and climate change.
