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.
The carbon sink in the land biosphere has grown during the past 30 years, taking up much of the carbon dioxide produced by human activities.The first signs of this growth levelling off have been spotted in Amazon forests. See Letter p.344.ut all has not been well with this picture. Those concerned with the constraints on vegetation growth caused by limiting resources (such as nutrients, water, heat or light) have warned against the idea that the land carbon sink will continue unchecked in the future.
