Climate Change - Carbon Sinks
are natural systems that suck up and store
from the atmosphere.
The main natural carbon sinks are
plants, the ocean and
grab carbon dioxide from the atmosphere to use in
; some of this carbon is transferred to soil as plants die and decompose.
are a major carbon storage system for carbon dioxide.
Marine life also takes up the gas for photosynthesis, while some carbon dioxide simply dissolves in the seawater.
35 billion tonnes
of CO2 are produced each year by human activities.
Currently, natural processes are absorbing about 50% of that.
The figure of 33.4 billion metric tonnes of carbon dioxide is for 2010.
The remaining carbon dioxide is building up in the atmosphere.
