Scientists measure the concentration of carbon dioxide in ice cores from the Arctic and Antarctic and use these measurements to estimate historic atmospheric emissions (Lewis 2015). These reconstructions and recent observed data show that the pre-industrialization atmospheric carbon dioxide concentration ranged between 200 and 300ppm while post-industrialization concentrations have steadily increased from approximately 300ppm to 400ppm. As mentioned earlier, scientific research shows that human activity is a major factor in this rapid increase in atmospheric carbon
