  1. Factually incorrect and literally tens of thousands of scientific papers have been published that prove your statement false. I am however intrigued, could you please cite your qualifications and published work. Thanks.

  2. Children in high schools conduct this experiment every day of the week. It is sad our education system failed you. As an experiment that can be done in the home or the classroom, fill one soft drink bottle with CO2 (perhaps from a soda machine) and filling a second bottle with ambient air. “If you expose them both to a heat lamp, the CO2 bottle will warm up much more than the bottle with just ambient air,”. check the bottle temperatures with a no-touch infrared thermometer. You’ll also want to make sure that you use the same style of bottle for each, and that both bottles receive the same amount of light from the lamp
