Concept explainers
Climate scientists have become increasingly concerned that rising levels of carbon dioxide in the atmosphere (produced by the burning fuels) will affect the global climate in harmful ways such as increased temperatures, rising sea levels, and coastal flooding. The graph at right shows the concentration of carbon dioxide in the atmosphere from the mid-1800s to the present time. Study the graph and answer the questions that follow.
Atmospheric Carbon Dioxide
(a) What were the carbon dioxide concentrations in 1950 and 2000? How much did the carbon dioxide concentration increase during these 50 years?
(b) What was the average yearly increase between 1950 and 2000?
(c) Beginning from the carbon dioxide concentration in 2010 (390ppm), and assuming the average yearly increase you calculated in part b, what will the carbon dioxide concentration be in 2050?
