Basically, carbon sinks are holding tanks for carbon or carbon compounds, like carbon dioxide (CO2). One of the largest reservoirs of carbon is the Earthâs hard rock crust. Over the eons sedimentary rocks were formed that contain loads of carbon compounds, including the hydrocarbons that we now use as fossil fuels.
A carbon sink is anything that absorbs more carbon that it releases, whilst a carbon source is anything that releases more carbon than is absorb.Forests, soils, oceans and the atmosphere all store carbon and this carbon moves between them in a continuous cycle.This constant movement of carbon means that forests act as sources or sinks at different times. Not all stores of carbon are naturally cursed with such fluctuations however.In the context of climate change, the most important carbon stores are fossil fuel deposits as they have the unique benefit of being buried deep inside the earth, naturally separated from the carbon cycling in the atmosphere.ecause of this increase in atmospheric carbon, a lot of emphasis and hope has been put into the ability of trees, other plants and the soil to temporarily sink the carbon that fossil fuel burning releases into the atmosphere.
