In Depth – Carbon (Met Office)

Carbon Cycle Carbon (chemical element C) is one of the most abundant elements in the universe. All known life forms are carbon-based and it amounts to about 18% of a human body. Carbon dioxide (CO2) and methane (CH4) make up about 0.04% of our atmosphere by volume. However, alongside water vapour, nitrous oxide and ozone…
