There was 0.028%, now there is 0.04%, that rise is manmade. The simplest explanation is that although the oceans are warming and would be outgassing CO2, but looking at the ice core, an ocean warming of 1C can only produce about 5 or at most 10ppm rise. IOW earth would have gone from 0.028% CO2 to 0.029% CO2. Instead of that situation, the oceans are now ingassing net.
The very rough ratio 3.5% (you 3.4% above) comes from comparing man's production of CO2 in a year (about 30Gt) to the natural production of CO2 from oceans and decaying plant matter in a year, about 800 or 900 Gt. The natural flux is poorly measured.
But the natural flux goes in both directions. Mainly the greening of the northern hemisphere each spring and summer pulls lots of CO2. The oceans absorb the rest. So the (roughly( 850 is two directions. Manmade, 30 Gt is all output.

apparently you have different scientific figures than the rest?
[[but looking at the ice core, an ocean warming of 1C can only produce about 5 or at most 10ppm rise.]]
Warmign happens FIRST, then CO2 rises- them ore warming, the greater the rise- We’ve had this discussion many times and you never explain how wamrign can happen first, then decades later CO2 rises?
[[The natural flux is poorly measured.]]
Odd- but yet you are certain man is the cause for the rise
[[So the (roughly( 850 is two directions. Manmade, 30 Gt is all output]]
Big deal=- again- warming happens first, THEN CO2 rises- so CO2 can not be causing wamring- and secondly, man’s contribution of CO2 amoutns to just 0.00137% of the atmosphere- (man’s contribution of CO2 to the total atmospheric CO2 level of 0.04% is just 3.4% which eaquals just 0.00137% of the total atmosphere 3.4% of 0.04% = 0.00137%. You can keep touting ‘tons’ all youl ike, but the FACT remains that man is only contribution CO2 I nthe amount of just 0.00137% of the atmosphere
“’Scientists note that geologically speaking, the Earth is currently in a ‘CO2 famine’ and that the geologic record reveals that ice ages have occurred when CO2 was at 2000 ppm to as high as 8000 ppm. In addition, peer-reviewed studies have documented that there have been temperatures similar to the present day on Earth when carbon dioxide was up to twenty times higher than today’s levels’”
[[Manmade, 30 Gt is all output.]]
That’s funny because article after article I read states something along the lines of
“Oceans face higher acidity levels as more man-made CO2 gets absorbed”
(The site goes on to declare man is pumping out record amounts of CO2- and blames wamrign on CO2 rises, yet IGNORES the fact that temps have remained flat for nearly 2 decades now DESPITE ‘record man made CO2’ being pumped into atmosphere
Weird!
