Quadratically increasing CO2 emission will increase CO2 concentration cubically and also the Earth’s temperature

This is to demonstrate that as CO2 emissions (inflow, gigatons/year) increase quadratically (2nd order), the CO2 concentration (or atmospheric CO2 in gigatons, gt) will increase cubically (3rd order). Therefore, it can be logically concluded that Earth’s temperature will increase non-linearly (much faster) as there is a relationship between atmospheric CO2 and temperature. I used the relationship between speed and distance as an analogy.
◼
  • If CO2 emission is constant, then CO2 concentration will increase linearly over time.
  • ◼
  • If CO2 emission increase linearly, then CO2 concentration will increase quadratically over time.
  • ◼
  • If CO2 emission increase quadratically, then CO2 concentration will increase cubically (3rd order).
  • Analogy : {speed (meter/second) vs. distance (meter)} and {CO2 emission (gt/year) vs. CO2 concentration (gt)}
