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. Keywords: World’s population; atmospheric carbon; heat-trapping gas; paleoclimatology. 1. INTRODUCTION The surprising rate of growth for our accelerating carbon dioxide emissions globally is dramatically shown in Fig. 1 from a slide used in a 2019 slide presentation by this author (www.tinyurl.com/ValoneClimateSlideshow). Worldwide energy consumption reached a record 37 billion tons of CO2 (for a single year’s total emission) at the end of 2018, with the U.S, India, and China leading the increase. Note that only ten years before, the carbon dioxide annual emission rate was less than 30 gigatons. The total carbon emission growth rate in 2017 was only 1.7 percent while carbon growth for 2018 shown in Fig. 1 increased 2.7 percent (Fig. 1), thus proving an accelerating trend that has no foreseeable “peak” in the growth rate or the actual magnitude of carbon dioxide annual emissions in the near future. As for China, coal accounts for about 60 percent of China’s total energy consumption. [1] A major new paleoclimatology study also shows that current global warming has reversed the past 6,500 years of global cooling. [2] An increase in the chemical index of alteration and a kaolinite content up to 50 % of the clay fraction indicate an influx of terrestrial input shortly after the PETM onset and during the recovery, likely due to an intensified hydrological cycle. The volcanically derived minerals zeolite and smectite comprise up to 36 % and 90 % of the bulk and clay mineralogy respectively. [3-4] Global annual carbon dioxide emissions 1959-2018 as shown in Fig. 1 started a new exponential surge upwards in 2017. [5] Fossil fuel carbon emissions are now steadily increasing annually in several major countries in the world, which translates to the rate of growth having an upward slope, without a predictable peak, of either rate or magnitude, in the foreseeable future. Recent climate reports suggest
