Carbon dioxide mole fractions in the atmosphere have gone up by approximately 35 percent since the 1900s, rising from 280 parts per million by volume to 387 parts per million in 2009. Before the Industrial Revolution began in the mid-1700s, the concentration of carbon dioxide was about 280 ppm. Since then, the burning of fossil fuels and other human-related activities have increased the amount of CO 2 in the atmosphere by more than 40 percent.
