13. Suppose the current estimate for the [CO2 ], i.e., the answer to Question 7(a), corresponds to storage of 775 GtC in Earth’s atmosphere. (1 GtC is a GigaTon of C.) If the intention of the geoengineered sequestration of CO2 is to completely offset the effect of the 2x[CO2 ] climate scenario, what should be VeLaMiCarb’s target for C removal over the time frame dictated by your answer for Question 8 above? Explain. [3 marks]
