I don’t need to do my own research because scientists who DO do the research HAVE done the research and the verdict is now overwhelming and unequivocal.
And regarding your question about my point, it was that it is well understood why temperature changes always preceded CO2 changes until the last couple of centuries and why it is the other way around now. Indeed, all it takes is putting on one’s thinking cap.
So what was YOUR point in calling out the ice core data?

John do your own research into the data. I have done it for over 20 years. Your turn. If you just want to believe what people tell you about scientific data, that's your business.
The link you provided does not say anything different than I said. Your point?

There's nothing new about the fires, except now they are often the result of arson, bad forest and water management, or bad electrical equipment.

For the ice cores, in every case, temperature change leads the change in the CO2 concentration on the scale of hundreds of years, not the other way around (according to 9 peer-reviewed and published studies looking at the smaller time scales where those changes occur. You can see this in the data plotted to the screen in the video for some of the changes. The ice core data does indicate that its been more than 800 000 years since the CO2 concentration was higher than 300 ppm.
