<h3>What is the amount of carbon dioxide in the atmosphere?</h3>
Only 0.04% of the atmosphere is made up of carbon dioxide, and water vapor levels can range from 0% to 4%. However, while being the main greenhouse gas in our atmosphere, water vapor possesses “windows” that let some infrared light pass through without being absorbed.
