No it will be incomprehensible because mixed with other messages ... but I can divide towards a new ...

I put what title? Who wants to be the "creator" of the subject? : Cheesy:

So I would like to create a subject on: "Climate: natural variability vs anthropogenic influence?" :)

Rather "The fable of anthropogenic warming and the fight against CO2" I answered you elsewhere. http://econologie.com/forums/catastroph ... ml#p379090

Well the calculation is quite simple and that's good I updated this page yesterday: https://www.econologie.com/emissions-co ... el-ou-gpl/

We have the following mass reports:

One liter of gasoline that weighs 0,74 kg emits 2,3 kg of CO2 and 1 kg of water
A liter of diesel (or diesel or fuel oil) that weighs 0,85 kg rejects 2,6 kg of CO2 and 1,15 kg of water

Gasoline: 2,28 / 0,74 = 3,08 kg CO2 / kg of gasoline (we find the value: 3,09)
Diesel: 2,67 / 0,85 = 3,14 kg CO2 / kg diesel (we find the value: 3,16)
LPG: 1,66 / 0,55 = 3,02 kg CO2 / kg LPG (we find the value: 3,02)


We can therefore leave on a reasonable basis by a factor of 3!

Each kg of oil burned has therefore "enriched" the atmosphere with 3 kg of CO2 ... and 1,35 kg of water! **

Suppose that 85% of the oil consumed has been burned (hey yes, think about roads, plastics, solvents ...), knowing the mass of all the oil that has already been burned * CO2 additions are easily obtained by just oil with a factor of 0.85 * 3 = 2,6

It will be enough to know the mass of the atmosphere to have the ppm. Do the same reasoning for the other fossil fuels gas and coal ... and we will have an idea of ​​the GigaTonnes of CO2 that we put in the air!

* I let you look for this value.

** all "specialists" claim that fossil water does not contribute to warming, however water is the 1st greenhouse gas. Okay, the contribution of fossils is low compared to that of natural evaporation, but I am convinced that the influence of fossil water is not negligible: not only does it take up O2, as does CO2, from the atmosphere but it will increase the greenhouse effect and natural evaporation also ... at least locally (city blocks)!


Note: the emission ratio of coal, assumed to be pure carbon, is CO2 / C = (12 + 16 * 2) / 12 = 3,7 kg ... It is "only" 3.7 / 3 = 1.22 or 22% more than oil!

1 ppm of CO2 corresponds to 2.12 Gt of CO2 (source IPCC and Gilbert Masters)
Between December 2018 and December 2019, the CO2 concentration increased from 409.07ppm to 411.76 ppm, or 2.69 ppm.

This makes 5,7 Gt of CO2 in the atmosphere more in 2019, for 40 Gt emitted.

34 Gt in the oceans and captured by vegetation and 5,7 in the atmosphere.
The decline in ocean pH is 0,0017 ± 0,0003 units per year (2004 data).

If we didn't have as much water in the oceans, the planet would have been charred for a long time. The PH has already gone from 8,25 to 8,14.

you must have planted yourself there ... since we emit around 35 Gt of CO2 per year, that half remains in the atmosphere, and that it increases by 2 ppm per year, that makes rather 8 Gt CO2 for 1 ppm with a ladle (or else you took the figure in Gt C, gigabyte of carbon, and no CO2).
