摘要

As the world’s population has tripled(3x)since 1950,with another 50%increase expected by 2100,global annual carbon dioxide emissions growth rate has quadrupled(4x)since 1950 and global energy demand has quintupled(5x),all in the same time period.This discontinuous combination can be called a“3-4-5 Triad”and the sudden acceleration in all three arenas is too stressful on the environment and the damaging effects will be felt globally for centuries to come unless drastic action is taken.More importantly,the energy demand at 5x is outstripping the other two.This clearly means that as the population explodes at 3x,the emerging middle class wants almost twice as much as their usual share as fossil-fueled generators spread around the globe and modern conveniences become more and more desirable.However,such energy demand at 5x is an artificial human need that is predicted by RMI.org to result in four to five billion new window-mounted air conditioners by 2050 that will add even more to the global warming caused by increasing atmospheric carbon.By an examination of paleoclimatology for the past 420,000 years,it is demonstrable that reducing the concentration of this single most prolific heat-trapping gas by geoengineering back to pre-industrial levels of less than 300 ppm can actually give humankind a collective control over the world’s rapidly rising average global temperature and once more,a temperate climate to live in.
