Truth about greenhouse gases... worth a read

I am a strong supporter of a clean environment. We need to be vigilant to keep our land, air, and waters free of real pollution, particulates, heavy metals, and pathogens, but carbon dioxide (CO2 ) is not one of these pollutants. Carbon is the stuff of life. Our bodies are made of carbon. A normal human exhales around 1 kg of CO2 (the simplest chemically stable molecule of carbon in the earth’s atmosphere) per day. Before the industrial period, the concentration of CO2 in the atmosphere was 270 ppm. At the present time, the concentration is about 390 ppm, 0.039 percent of all atmospheric molecules and less than 1 percent of that in our breath. About fifty million years ago, a brief moment in the long history of life on earth, geological evidence indicates, CO2 levels were several thousand ppm, much higher than now. And life flourished abundantly.

I agree with what the author states in the above paragraph. My understanding of the prehistoric record of the earth made me realise that claims that the earth had never been hotter, held more atmospheric CO2, all these high temperatures were breaking records and we were going to burn the earth to a crisp really pushed  all the wrong  buttons for me because those proffering these forecasts of imminent doom and destruction were disregarding the entire history of the earth which is held in geological records, set in stone so to speak.
