From the graph below, which shows carbon dioxide concentration in the atmosphere: Carbon dioxide concentration ppmv 360 350 340 330 320 310 1960 1970 = 320 1990 350 1970 Year 1980 1990 a. Define the exponential increase in carbon dioxide with time. b. If the toxic concentration of carbon dioxide is 1% volume, when (year) will the earth become uninhabitable if this rate of increase continues? (Ans. Year 2738) C. Gasoline use has increased from 1 tonne in 1880 to 1 Gtonne in 1990 and the increase has been exponential. Derive the equation describing this increase. d. If this increase continues and reserves in 1990 were 3000 Gtonne, when will the reserves be exhausted? Will we be poisoned or run out of fuel? (Ans. Year 2023)
