Concentration of CO, in the Atmosphere Levels of carbon dioxide (CO) in the atmosphere are rising rapidly, far above any levels ever before recorded Levels were around 27 parts per million in 1800, before the Industrial Age, and had never, in the hundreds of thousands of years before that, gone above 300 ppm, Levels are now over 400 ppm. The table below shows the rapid rise of CO, concentrations over the 55 years from 1960-2015 also available in CarbonDioxide. We can use this information to predict CO, levels in different years Year CO 1960 316.91 1965 320.04 1970 325.68 1975 331.11 1980 338.75 1985 346.12 1990 354.39 1995 360.82 2000 369.55 2005 379.80 2010 389.90 2015 400.83 (e) What is the intercept of the line? Round your answer to one decimal place The intercept is -2571 Does it make sense in context? No (g) Find the residual for 2010.
