Disaggregated growth rates for three scenarios are given in the following table: For each scenario, Predict CO_2-induced global equilibrium temperature increase in 70 years, if the initial C02 concentration is 356 ppm, the initial emission rate is 6.0 Gt/Cyr, and the initial atmospheric carbon content is 750 GtC. If those growth rates continue, in what year would CO_2 concentrations be equal to double the initial 356 ppm
