Ok greenhouse gases are 1-2% of the atmosphere. Let’s go with 2% & 95% of that is water vapor with another 1.38% being a gas other then water vapor. So (95 + 1.38 = 96.38) then (100 - 96.38 = 3.62), so 3.62% of that greenhouse gas is CO2 per annum. Humans contribute only 3.4% of the annual CO2 greenhouse gas submission. So what have we done to bring it back to frightening levels? It’s not at Cambrian (Trilobite Park) levels, is not even at Jurassic Park levels! It’s not even as warm as Roman times, medieval times & we’re still coming out of the “Little Ice Age” !
Heck technically we are still in a Ice Age - the Quaternary! “ Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets associated with Milankovitch cycles and the associated climate and environmental changes that occurred”. No geologist that I am aware of has said here’s the physical evidence we have left the Quaternary.
Cyclic growth and decay of continental ice sheets are the key words . They’ve decayed and the best way to place your bets is - THEY’RE COMING BACK! So its been said before “Winter is Coming!”
You analysis is sloppy and flawed. I would be cautious drawing too many conclusions from it. Human contribution to “greenhouse warming” cannot be dismissed out of hand, as you appear to be attempting to do. Nor should we become hysterical and panicky because of dubious trends based on doctored data.
