5. Determine the annual and cumulative emissions for CO2 for following scenario for 2010 to 2100: population growth varies linearly from 1.5%/ yr to 0 over 70 years (then remains at zero), world economic growth is 1.5%/yr, change in energy intensity of the economy is (1.5)%/yr, and the average energy source composition (the fraction of each source) changes linearly from 2010 to 2100 according to Table 1. In the year 2010 , anthropogenic emissions of carbon due to energy use are 9.3GtC/yr. Table 1. Energy Mixtures
