I assume by historical you mean paleontological/geological records? Otherwise that statement is not correct. We are at 560 ppm CO2eq right now or 420+ ppm CO2. The last time CO2 alone was this high was about 14 million yrs ago. Over the last million years CO2 has alternated between highs of around 280 during interglacials and lows of 180 during the glacials. We were presently trending into a glacial period although it was not expected to be as severe as the last one due to our present alignment of the Milankovitch cycles. The temperature change during these transitions was around 1.5C per 2000 yrs. Plants arent CO2 limited.until you can verify the difference don't do anything. The historical record shows that there was more CO2 a long time ago. Temperatures were higher, a long time ago. Oh and CO2 levels were lower a long time ago and temperatures were lower a long time ago. And we had nothing to do with any of them a long time ago. And those higher temperatures a long time ago were higher than the UN's panic threshold. CO2 is a trace gas. As far as they can tell, an increase in CO2 improves plant growth which means we eat better and cheaper. The burning of hydrocarbons has resulted in you living longer and better and warmer in the winter and cooler in the summer. It has meant that you can show your kids around Niagara Falls one week and go skiing in Lake Placid the next. The so called cures for global warming involve giving up on all of the above. Are you sure that is what you want? Remember, you haven't determined that they will even work. You are trusting the same people who said Covid came from a Chinese bat market to not be lying to you. That to me is about as valid as following the lead of Jimmy Jones
The rest of what you said has nothing to do with AGW directly
