One of the things that scientists rely on to accurately predict climate change is the amount of carbon sequestered underground. Carbon dioxide in the air leads to increased global warming, exacerbating climate change. When plants have a lot of access to carbon dioxide, they photosynthesize more. Scientists have assumed for a long time that this led to a high concentration of carbon sequestered under the ground. As plants took in this carbon dioxide, they transformed it into compounds and organic structures such as roots and leaves, which would add to the amount of carbon stored underground.
