Question

Quizplus · Accepted Answer

All of the statements are correct. Increasing carbon dioxide in the atmosphere contributes to global warming because carbon dioxide is a greenhouse gas that traps heat in the atmosphere. When burning a 100-year-old pine tree in one hour, we put back into the atmosphere the amount of carbon dioxide that the pine tree took 100 years to incorporate because the carbon in the tree was originally taken from the atmosphere through photosynthesis. Today, we burn a lot more than our ancestors because we have a much larger population and we use more energy. Under normal circumstances, extra carbon dioxide stimulates photosynthesis because plants use carbon dioxide to make food.
