The amount of carbon stored in dry wood is approximately 50% by weight.

They calculated the amount of carbon stored above ground and in the roots.

Therefore, the amount of carbon on Earth is effectively constant.

Also keep in mind that the greenhouse effect isn't dependent only on the amount of carbon.

This is roughly the amount of carbon already stored in the atmosphere today.

The good news is that not all fuels store the same amount of ancient carbon.

Large amounts of carbon are exchanged each year between the ocean and the atmosphere.

He also demonstrated the amounts of carbon and nitrogen in natural water.

Forest fires can add significant amounts of carbon into the air.

The higher the amount of carbon present in the iron, the harder and stronger it is.
