2.7 CO2 emissions add up every year
A series of rapidly rising CO2 impulse spikes from increasing yearly CO2 emissions add together into a very large accumulating effect
Human’s use of Fossil Fuels since the 1850’s through to 2021 has, in effect, been producing a yearly CO2 impulse spike each and every year. Every year the amount of CO2 emissions has been increasing, so the size of each yearly impulse spike has been effectively increasing. Every one of these yearly CO2 impulse spikes since the 1850’s is, in effect, being accumulated into long lasting and very large concentration of CO2.
The accumulating concentration of CO2 has a time-delayed effect on Average Earth Temperature which is already starting to grow, and because this thermal energy is being stored in the oceans and building momentum, once it starts, it is going to be HARD TO STOP !
Chart B shows the concentration of CO2 that humans have been putting into the Earth’s Atmosphere, and it provides an estimate of what would happen if humans completely stopped putting CO2 into the atmosphere from the following date:
2015 – this shows the CO2 will not fall below 325 ppm for over 500 years, and we passed this point 6 years ago.
2030 – this shows the CO2 will not fall below 340 ppm for over 500 years, and that is just 9 years from now.
2050 - this shows the CO2 will not fall below 375 ppm for over 500 years, and that is 29 years from now.
Right now, the Earth’s CO2 concentration level is 417 ppm, and it is certain that it will become progressively higher every single year because of CO2 emissions in past years.
Now Stop! Take a break for 5 minutes and just THINK VERY CLEARLY ABOUT WHAT THIS MEANS, AND DEEPLY UNDERSTAND WHY RAPID EMISSION REDUCTIONS ARE SO CRITICAL.
Decay of atmospheric CO2 perturbations:
(A) Instantaneous injection or extraction of CO2 with initial conditions at equilibrium. Response to an impulse spike in CO2
(B) Fossil fuel emissions terminate at the end of 2015, 2030, or 2050 and land use emissions terminate after 2015 in all three cases, i.e., thereafter there is no net deforestation.
