The 96% Natural CO2 is good CO2, the 4% human made is bad CO2 you see, it will bring the world to a catastrophic tipping point and cause global warming um... climate change uh... climate disruption, yeah that's it. That sounds scary enough.

Nothing I learned about thermodynamics explains delayed warming.
Heat does not accumulate in an open system where excess heat energy can radiate into space every night, it will merely find a new equilibrium very quickly.

The 200 Gt of natural CO2 produced per year (mainly fall and winter) is also absorbed for the most part in spring and summer. In the case of the 8Gt or so (4% of 200) that man produces, almost all of it stays. But nature obviously does not know or care about the difference, it is all CO2

What happens is that nature tries to bring the current 400ppm back down to maybe 300ppm which would be short term equilibrium. To do that, nature absorbs a bunch into the ocean. At that point some is sequestered there (precipitates into some form and falls to the bottom). So in a net calculation, the increased CO2 in the atmosphere is all manmade and would be even higher without the ocean absorption.

If man were not around CO2 would have risen naturally due to warming after the Little Ice and prior warming (e.g. Medieval Warm Period) with a lag. But that would amount to a small increase, 5-10 ppm maybe, not the 120 ppm we have seen and not the 2-3 ppm rise per year we measure.

Thank you BitWielder1 for this post

I took thermodynamics at Rutgers in 1976, I don't think the laws have changed since...So, I just use my hashtag #AlGoreBullWarming on everything!
