> They don’t know that the average level of CO2 over the last 250 million years is 1200 ppm
That's kind of what I gathered in my research. There is an incredible lack of understanding by the average person just how many things that we've been taught to believe in school are completely false, and science is no exception. Furthermore, scientists have to relay on funds to conduct research, which again gets reflect through the political/globalist agenda. Our ice cores probably only go back some 5,000 years or less. Research uniformitarianism vs catastrophism if you want to learn more.
