What does carbon dioxide have to do with humans? Carbon dioxide acts as a simple asphyxiant; in other words, as CO2 levels in a closed room rise, carbon dioxidereplaces the oxygen your body needs. When your body can't get oxygen, it slows down and does not function properly. Because c...
Plants use carbon dioxide to produce carbohydrates (sugars and starches) in the process known as photosynthesis. (In photosynthesis, plants make use of light to break down chemical compounds and produce energy.) Since humans and all other animals depend on plants for their food, photosynthesis is...
Humanshave disturbed the biological carbon cycle for many centuries by modifyingland use, and moreover with the recentindustrial-scale miningof fossil carbon (coal,petroleumand gas extraction, andcementmanufacture) from the geosphere.Carbon dioxidein the atmosphere had increased nearly 52% over pre-ind...

To find a time period where carbon dioxide levels were this high, we need to trace back all the way to the Pliocene Epoch, at least 2.2 million years ago! Research has shown that CO2 levels were around 400 ppm. That is before the earliest humans (Homo habilis) ...
Carbon dioxide in the atmosphere has reached levels never experienced by humans. SEE: The Top Cartoons on Climate Change and Global Warming For the first time in the past 800,000 years, the concentration of carbon dioxide in the atmosphere is over 415 parts per million...
