C02 Levels in the atmosphere

The new way humanity must look at C02

We are a 730 species living in a 1230 world


As set forth in Chapter 7 of “This Spaceship Earth” we must stop looking at levels of emissions and instead focus on resident CO2 in the atmosphere. Carbon remains in the atmosphere for decades and centuries. Before the Industrial Age the amount of resident CO2 was 730 Gigatonnes. This remained constant until the 20th century when it crossed 800 around WWII and then 830 in 1970. We have since added 400 Gigatonnes to the atmosphere.




In the last 45 years the amount of resident CO2 has increased 400 GT to 1230. It is during this time period that we have experienced warming and climate change.


The new TSE crew conscious goal is to reduce the total amount of resident CO2 to 800 in 45 years or less. As shown in the the book, the Paris Accord -IF all countries fulfilled their agreements – would add another 600 GT by 2050. A true path to disaster.


So the new goal for humanity is to get back to 800 GT of resident CO2 in the atmosphere ASAP!
