Almost doubled (from .2 to almost .4)
Carbon dioxide levels in the atmosphere have increased by approximately 40% since the start of the Industrial Revolution about 150 years ago. This increase is primarily due to the burning of fossil fuels for energy and deforestation, leading to higher concentrations of CO2 in the atmosphere, contributing to global warming and climate change.
Acid rain has increased in the past 200 years due to human activities such as burning fossil fuels, industrial processes, and transportation emitting sulfur dioxide and nitrogen oxides into the atmosphere. These pollutants combine with water vapor in the air to form sulfuric acid and nitric acid, leading to acid rain.
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.
Humans have significantly altered the Earth's atmosphere in the past 200 years by increasing the concentration of greenhouse gases, primarily carbon dioxide, through activities like burning fossil fuels and deforestation. This has led to global warming and climate change, impacting weather patterns, sea levels, and ecosystems worldwide.
Due to the phenomenon known as global warming, the surface temperature of the earth is increasing every year. It is warming in some areas more than others and over the last century, the temperature has increased an average of 13 degrees.

By 38 percent
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.
